7:23AM

DAYS 1-5 (NOVEMBER 13-17)…
Dry air returns today but it won’t be a totally sunny day as another trough will approach from the northwest and provide some instability for cloudiness, and perhaps a rain shower this evening as it passes, introducing colder air for the weekend. The coldest day will be Saturday, along with plenty of wind. Sunday will be less windy and slightly less chilly, temperature-wise, but feel much less colder overall than Saturday due to the lack of wind in comparison. Fair weather and a warming trend will be well-underway as high pressure dominates both at the surface and aloft early next week.
TODAY: Sunshine most dominant this morning, clouds more dominant this afternoon. Highs 55-62. Wind W 15-25 MPH with higher gusts.
TONIGHT: Lots of clouds evening with a passing rain shower. Lows in the 30s. Wind W 10-20 MPH with higher gusts, shifting to NW.
SATURDAY: Partly cloudy. Isolated rain/snow showers possible. Gusty wind. Highs 45-52.
SUNDAY: Mostly sunny. Lows 26-33. Highs 45-52.
MONDAY: Sunny. Lows 20s interior, lower 30s coast and urban areas. Highs in the 50s.
TUESDAY: Sunny. Lows in the 30s. Highs 55-65.

DAYS 6-10 (NOVEMBER 18-22)…
Some cloudiness at times otherwise dry November 18-19 with temperatures above to much above normal. Rain showers possible as a cold front approaches November 20, and this may linger into November 21. Fair and colder November 22 as the front pushes away and high pressure moves in from Canada.

DAYS 11-15 (NOVEMBER 23-27)…
The overall pattern continues mild but temperatures during this period will likely be more variable due to some passing systems in the northern jet stream as the high pressure ridge weakens and allows a couple of fast-moving troughs to come through the northeastern US. Any precipitation events should be brief. Since Thanksgiving falls in this time period (November 26) I’ll try to work out timing and details as soon as possible.

7:22AM

DAYS 1-5 (NOVEMBER 12-16)…
A damp November chill will be evident today as we hold onto an overcast and then see more wet weather later in the day and this evening as another low pressure system impacts the region. Unlike its predecessor, this low will track north of southern New England and pull a warm front through today followed by a cold front later tonight. Behind this initial cold front the air will not actually be that cold, so Friday will end up being on the milder side, though a gusty wind will make it feel a little cooler than it is as it will turn out dry during the day. A second cold front from the northwest will bring a risk of rain showers in the evening just before colder air rushes in with its passage. This will set up a chilly and windy day Saturday with just an outside risk of a sprinkle of rain or light flurry of snow from passing clouds. Sunday ends up sunnier and less windy as high pressure builds more overhead. This bright weather will continue Monday but along with the start of a warming trend.
TODAY: Cloudy. Areas of light fog this morning. Rain showers arriving west to east this afternoon. Highs 48-55. Wind light variable mainly NE in the morning, S 5-15 MPH in the afternoon.
THURSDAY NIGHT: Cloudy with rain showers evening, ending west to east with breaking clouds overnight. Lows in the 40s. Wind S 10-20 MPH shifting to W with some higher gusts.
FRIDAY: Sunshine and passing clouds. Highs 55-62. Wind W 15-25 MPH
FRIDAY NIGHT: Lots of clouds evening with a passing rain shower. Lows in the 30s. Wind W 10-20 MPH with higher gusts, shifting to NW.
SATURDAY: Partly cloudy. Isolated rain/snow showers possible. Gusty wind. Highs 45-52.
SUNDAY: Mostly sunny. Lows 26-33. Highs 45-52.
MONDAY: Sunny. Lows 20s interior, lower 30s coast and urban areas. Highs in the 50s.

DAYS 6-10 (NOVEMBER 17-21)…
A stretch of mainly dry weather with temperatures rebounding to above to much above normal as high pressure dominates. Perhaps a risk of rain showers by late November 20 to early November 21 depending on the timing of a front.

DAYS 11-15 (NOVEMBER 22-26)…
The overall pattern continues mild but temperatures during this period will likely be more variable due to some passing systems in the northern jet stream as the high pressure ridges weakens and allows a couple of fast-moving troughs to come through the northeastern US. Any precipitation events should be brief.

7:27AM

DAYS 1-5 (NOVEMBER 11-15)…
Everything going about as expected with the coastal (or just off the coast) storm system making Veterans Day damp, chilly, and windy. This system was expected to under-produce in rainfall based on model forecasts, and is doing that, though a few bands of moderate to heavier rain are still possible this morning as this system intensifies and moves northeastward off the New England coast. Some minor to locally moderate coastal flooding is expected near high tide times today, with east-facing and north-facing coastlines most vulnerable. The storm exits in full tonight and clouds that start to clear out later in the day far inland will finally exit most of the coastline, though some lower cloudiness may linger in parts of southeastern MA, only to spread over more of the region as high and middle clouds increase from the west on Thursday ahead of a Great Lakes low pressure area pushing a front toward New England from the west. By later Thursday, an overcast will be dominant and some additional wet weather is likely. But this system will also be moving right along and drier air will sweep in behind its first cold front for Friday, along with a gusty wind but fairly mild air. The colder air lies behind a second front which will pass from northwest to southeast Friday evening, not without the risk of a rain shower and even a snow shower over areas further northwest of Boston if the cold air comes in quickly enough while any precipitation is still falling. On Saturday expect just enough instability around for passing clouds interrupting bright sun. A few of these clouds may even produce a passing sprinkle or snow flurry. By Sunday, a sunnier but chilly November day is expected.
TODAY: Overcast morning with periods of rain and drizzle along with areas of fog. Mainly cloudy afternoon with lingering sprinkles of rain, but enough breaking of clouds for possible sun in northwestern RI, central MA, and southwestern NH for a while. Highs 45-51. Wind NE to N 15-25 MPH with higher gusts, especially along the coast, gradually diminishing during the afternoon.
TONIGHT: Variably cloudy southeastern MA, partly cloudy elsewhere. Fog forming in some valleys. Lows 38-45. Wind N up to 10 MPH but still gusty near the coast very early, then becoming light variable.
THURSDAY: Some early sun possible otherwise mainly cloudy. Rain showers arrive west to east by late. Highs 48-55. Wind light variable in the morning, S 5-15 MPH in the afternoon.
THURSDAY NIGHT: Cloudy with rain showers evening, ending west to east with breaking clouds overnight. Lows in the 40s. Wind S 10-20 MPH shifting to W with some higher gusts.
FRIDAY: Sunshine and passing clouds. Highs 55-62. Wind W 15-25 MPH
FRIDAY NIGHT: Lots of clouds evening with a passing rain shower, perhaps mix/snow shower northwest of Boston. A quick temperature drop possible evening leading to overnight lows in the 30s. Wind W 10-20 MPH with higher gusts, shifting to NW.
SATURDAY: Partly cloudy. Isolated rain/snow showers possible. Gusty wind. Highs 45-52.
SUNDAY: Mostly sunny. Lows 26-33. Highs 45-52.

DAYS 6-10 (NOVEMBER 16-20)…
A stretch of mainly dry weather with temperatures rebounding to above to much above normal. Perhaps a risk of rain showers by the end of the period.

DAYS 11-15 (NOVEMBER 21-25)…
A mainly dry pattern continues and at least starts warmer than normal, though a passing system about the middle of the period may produce some unsettled weather and a shot of cold air may arrive late in the period.

7:28AM

DAYS 1-5 (NOVEMBER 10-14)…
Low pressure moves up from the southwest off the coast later today through Wednesday bringing some unsettled weather. Some areas may see some beneficial rain but a fair amount of that may actually miss just offshore or only clip parts of the region. It’ll be a radar-watching kind of system. This low will be slow to wander away Wednesday, making it a damp, windy, and chilly Veterans Day, though most of any rain will occur early in the day as it appears now. Another system from the west will throw more clouds into the region for Thursday and bring some additional wet weather. Friday and Saturday will be windy and cool but dry days, other than possibly an instability shower of rain or snow in a few areas Saturday.
TODAY: Mostly cloudy. Periods of rain developing during the afternoon mainly South Coast and Cape Cod. Highs in the 50s. Wind E to SE up to 10 MPH.
TONIGHT: Cloudy. Periods of rain. Areas of fog. Lows in the 40s. Wind E 5-15 MPH becoming gusty overnight and shifting to NE.
WEDNESDAY – VETERANS DAY: Cloudy. Periods of rain mainly early to mid morning. Temperatures holding in the 40s. Wind NE 10-20 MPH inland and 15-30 MPH coast with higher gusts, shifting to N.
THURSDAY: Cloudy. PM rain showers. Lows around 40. Highs around 50.
FRIDAY: Partly cloudy and windy. Lows in the 30s. Highs in the 50s.
SATURDAY: Partly sunny and windy. Isolated rain or snow showers. Lows in the 30s. Highs around 50.

DAYS 6-10 (NOVEMBER 15-19)…
Dry with a warming trend November 15-18. Possible wet weather about November 19.

DAYS 11-15 (NOVEMBER 20-24)…
Up and down temperatures as a few disturbances roll through producing some unsettled weather at times.

7:33AM

DAYS 1-5 (NOVEMBER 9-13)…
High pressure today – cool and bright. Low pressure approaches from the southwest Tuesday and sends clouds into the region but the rain may fail a little as it tries to move through late in the day and at night, with much of it staying off to the southeast. We’ll see if a heavier band or two get involved over parts of southeastern MA and RI. Low pressures lingers a little bit Wednesday, Veterans Day, and may result in clouds and some damp weather hanging on. Another system approaches from the west Thursday with more cloudiness and eventual rain showers, then look for this system to push a front through by Friday which will turn out to be a windy and cooler day with drier conditions returning.
TODAY: Mostly sunny. Highs around 60. Wind W to SW 5-15 MPH.
TONIGHT: Partly cloudy. Lows in the 40s. Wind light SW to SE.
TUESDAY: Mostly cloudy. Chance of rain mainly southern MA and RI later in the day. Highs in the 50s. Wind SE to E 5-15 MPH.

Mainly dry weather during the period with temperatures near to above normal.

DAYS 11-15 (NOVEMBER 19-23)…
Watch for 1 or 2 systems with unsettled weather threats. Temperatures near to above normal.

1:07PM

DAYS 1-5 (NOVEMBER 8-12)…
Skipping a detailed discussion and will elaborate in the comments section below later today. No significant changes anyway.
THIS AFTERNOON: Sunny. Highs 48-55, coolest interior higher elevations. Wind NW 10-20 MPH with higher gusts.

DAYS 6-10 (NOVEMBER 13-17)…
It looks like the system will be progressive enough to move away by Friday November 13 with windy/cool/dry weather, continuing into Saturday November 14, then fair and slightly milder weather by Sunday November 15. Mainly dry and milder November 16-17.

DAYS 11-15 (NOVEMBER 18-22)…
The general pattern will continue to favor an overall mild/dry regime but with a couple quick unsettled events and brief cooler shots, depending on timing of systems.

7:47AM

DAYS 1-5 (NOVEMBER 7-11)…
The weekend will see a cooling trend, though today will still be fairly mild compared to average, albeit with limited sun due to plentiful high and middle cloudiness moving up from the southwest as a low pressure waves forms and passes southeast of New England on the recently-passed front. High pressure pushes it all eastward tonight and Sunday, which turns out to be clear, crisp, and cool. High pressure slides offshore Monday and Tuesday at which time a warming trend will get underway, first with a sunny Monday then some increase in cloudiness Tuesday as a disturbance approaches from the southwest. This system may bring brief wet weather to parts of the region Tuesday night but should move along and give way to weak high pressure in time for decent weather for Wednesday, which is Veterans Day.
TODAY: Sun filtered by a high overcast and at times blocked by considerable middle cloudiness. Highs 60-65. Wind W 10-20 MPH with higher gusts.
TONIGHT: Partly cloudy evening. Clearing overnight. Lows 35-40 interior, 40-45 coast. Wind NW 5-15 MPH and gusty.
SUNDAY: Sunny. Highs 48-55, coolest interior higher elevations. Wind NW 10-20 MPH with higher gusts.
MONDAY: Sunny. Lows in the 30s. Highs in the 50s.
TUESDAY: Increasing clouds. Possible rain at night. Lows in the 40s. Highs in the 60s.
WEDNESDAY – VETERANS DAY: Partly sunny. Lows in the 50s. Highs in the 60s.

DAYS 6-10 (NOVEMBER 12-16)…
Low pressure system approaches from the west November 12 bringing clouds and eventually some rain. Conflicting information as to whether or not this system moves away November 13 or lingers for additional unsettled weather as it redevelops nearby, but leaning toward the lingering scenario now. Improving weather by November 14 though with possible wind and brief cold. Fair, chilly then moderating November 15-16 based on current timing.

DAYS 11-15 (NOVEMBER 17-21)…
The general pattern will continue to favor an overall mild/dry regime but with a couple quick unsettled events and brief cooler shots, depending on timing of systems.

7:17AM

DAYS 1-5 (NOVEMBER 6-10)…
Unseasonable warmth and humidity today ahead of a cold front along with a variety of clouds. Some record high temperature will likely fall today. Boston’s record high of 73 may be eclipsed by 1 or 2 degrees as I expect them to reach 74 or 75. Only a few isolated rain showers this evening mark the passage of the cold front as it moves west to east across southeastern New England, and only slowly settles off to the southeast on Saturday, which will be cooler and much less humid. But you’ll have to wait another day for a more seasonable November chill as the coolest air will not arrive until Sunday. By the start of next week, high pressure will have crested overhead Monday then moved offshore Tuesday with a new warm-up underway. Some moisture may increase during Tuesday bringing cloudiness and eventually some risk of wet weather by night, though the evolution and movement of that possible disturbance is still very much in question this far in advance.
TODAY: Variably cloudy including some sunshine. Highs 65-70 South Coast, 71-76 elsewhere. Humid. Wind SW 10-20 MPH with gusts as high as 30 MPH.
TONIGHT: Mostly cloudy. A passing evening rain shower possible. Lows 50-55. Lowering humidity. Wind SW 10-20 MPH with higher gusts, shifting to W.
SATURDAY: Limited sun at times morning with variable high and some middle clouds especially southeastern MA and RI, then trending sunnier afternoon. Highs 60-65. Wind W 10-20 MPH and gusty.
SATURDAY NIGHT: Partly cloudy evening. Clearing overnight. Lows 35-40 interior, 40-45 coast. Wind NW 5-15 MPH and gusty.
SUNDAY: Sunny. Highs 48-55, coolest interior higher elevations. Wind NW to N 5-15 MPH.
MONDAY: Sunny. Lows in the 30s. Highs in the 50s.
TUESDAY: Increasing clouds. Possible rain at night. Lows in the 40s. Highs in the 60s.

DAYS 6-10 (NOVEMBER 11-15)…
Fair weather returns November 11 with mild air. Unsettled weather possible with clouds returning November 12 and a chance of some wet weather November 13, possibly lingering into November 14 before fair weather returns late in the period with a possible brief shot of colder air.

DAYS 11-15 (NOVEMBER 16-20)…
The general pattern will continue to favor an overall mild/dry regime but with a couple quick unsettled events and brief cooler shots, depending on timing of systems.

7:19AM

DAYS 1-5 (NOVEMBER 5-9)…
High pressure slips offshore allowing a warmer southwest flow today and Friday, though some cloudiness will be around at times due to increasing moisture i the air as well as a weak disturbance passing through tonight and a cold front approaching later Friday. Either of these may produce brief rain showers but no widespread rain is expected. After the front passes Friday night, a cooling trend will take place this weekend with dry weather, though some cloudiness may linger for a time especially from the Boston area to Cape Cod on Saturday. By Sunday and Monday, high pressure will be building overhead again with more clear sky and great November weather, though not as warm as the recent and current stretch.
TODAY: Mostly to partly sunny. Highs upper 60s to middle 70s. Wind SW 5-15 MPH.
TONIGHT: Partly to mostly cloudy. Risk of passing light rain showers mainly south of Boston. Lows in the 50s. Wind SW 5-15 MPH.
FRIDAY: Mostly cloudy to partly sunny. Highs upper 60s to middle 70s. Wind SW 10-20 MPH and gusty.

7:25AM

DAYS 1-5 (NOVEMBER 3-7)…
A high pressure ridge will be the dominant feature in the eastern US including this area this week. Our only risk of brief rain showers will come from a passing disturbance Thursday night and cold front Friday night, otherwise the dry pattern goes on.

7:16AM

DAYS 1-5 (NOVEMBER 2-6)…
High pressure dominates with mainly dry weather and above normal temperatures which will vary a little with wind direction based on positioning of high pressure throughout the period. The only interruption may be from a small and weak disturbance that drifts through from the southwest late Thursday to early Friday with cloudiness and a risk of rain showers, and more cloudiness later Friday from an approaching cold front.

Some unsettled weather early in the period followed by a return to mostly dry weather. Temperatures near to above normal.

9:14AM

DAYS 1-5 (NOVEMBER 1-5)…
October is gone. November is here. The days of bluster and chill, right? Not always. We’ll have our share of that as the month goes on, but the month is going to start out with a stretch of dry and mild weather after a disturbance passes and brings a few rain showers today. The mild and dry weather that follows it will last a good deal of the coming week.
TODAY: Mostly cloudy with scattered rain showers through early afternoon, then breaking clouds later. Highs around 60. Wind SW 10-20 MPH with higher gusts.

THURSDAY: Sunny. Lows around 50. Highs around 70.

DAYS 6-10 (NOVEMBER 6-10)…
Low pressure passing to the north late Friday or early Saturday will drag a cold front through, likely with nothing but some cloudiness, and after an unseasonably warm Friday it may cool somewhat Saturday. High pressure dominates with fair weather and above normal temperatures November 8-10.

DAYS 11-15 (NOVEMBER 11-15)…
Watch for some cloudiness and perhaps a little wet weather early to mid period with timing uncertain. Return to dry weather late in the period when it may turn somewhat cooler.

Please post in the Contest section which can be found by going to the home page of the blog.

Give your best guess on total snowfall for the season for any or all of the following cities:
Boston MA
Worcester MA
Providence RI
Hartford CT (taken at Bradley, north of the city)

Bonus question: What date will the first 1 inch snowfall occur at Boston’s Logan Airport?

You do not need to guess all of the cities if you do not want to.

Deadline for guesses is 6PM Sunday November 15 and later that night a list will be compiled for each city as well as the bonus question.

This is for fun though you are allowed to put as much scientific thought into your guesses are you are capable of. Be nice! Good luck!

9:30AM

DAYS 1-5 (OCTOBER 31-NOVEMBER 4)…
A disturbance will move eastward across northern New England and southeastern Canada, passing north of southeastern New England early Sunday. This approach and passage of this system will bring some cloudiness later today into Sunday as warmer air moves in aloft and at the surface. It looks like any rain showers will be light and scattered. After that we enter a multi-day stretch of dry weather and above normal temperatures as high pressure dominates.
TODAY: Bright morning and midday sun. Filtered afternoon sun with increasing high clouds. Highs in the 50s. Wind S up to 10 MPH.
TONIGHT: Clouds gradually thicken. Trick-or-treat temperatures around 50. Overnight lows around 40. Wind SW 5-15 MPH.
SUNDAY: Mostly cloudy to partly sunny. A few passing light rain showers possible. Highs around 60. Wind SW 10-20 MPH with higher gusts.
MONDAY: Mostly sunny. Lows around 45. Highs around 60.
TUESDAY: Mostly sunny. Lows around 45. Highs around 65.
WEDNESDAY: Mostly sunny. Lows around 50. Highs around 70.

DAYS 6-10 (NOVEMBER 5-9)…
Mainly dry weather through the period. Temperatures much above normal November 5-6, cooling back to near to above normal November 7-9.

DAYS 11-15 (NOVEMBER 10-14)…
The overall pattern favors dry and mild weather but watch for quick-passing disturbances which may produce brief unsettled weather events and temperature changes one or 2 times.
