DAYS 1-5 (JANUARY 10-14)

A strong blocking pattern continues to keep our weather on the quiet side. This will not be changing during this 5 day period either as we see yet another storm system fail to organize while passing south of the region Tuesday, and another batch of energy fail to materialize into much as it goes by the region fairly unnoticeable by the middle of the week.

TODAY: Sun & some high clouds. Highs 35-42. Wind NW up to 10 MPH.

TONIGHT: Partly cloudy. Lows 17-24. Wind W under 10 MPH.

MONDAY: Variably cloudy. Highs 37-44. Wind SW up to 10 MPH.

MONDAY NIGHT: Variably cloudy. Lows 22-29. Wind SW under 10 MPH.

TUESDAY: Mostly cloudy. Highs 37-44. Wind W up to 10 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 23-30. Wind W up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 37-44. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Variably cloudy. Lows 25-32. Wind W up to 10 MPH.

THURSDAY: Variably cloudy. Highs 38-45. Wind SW 5-15 MPH.

DAYS 6-10 (JANUARY 15-19)

Blocking pattern continues. Activity in our area increases during this 5-day period, starting with a low pressure area tracking northwest of the region, a milder day with a risk of rain showers January 15 followed by a drier/colder start to the Dr. MLK Jr. weekend January 16-17 which may end with a rain/mix/snow threat on January 18 before fair weather returns again.

DAYS 11-15 (JANUARY 20-24)

Monitoring for a weakening of the blocking pattern and a somewhat more active storm track into the Northeast. A lot of uncertainties out this far.

DAYS 1-5 (JANUARY 9-13)

A quiet weekend as our ongoing blocking pattern shunts the storm track to the south, with one passing out to seas well south of the region today before high pressure builds in Sunday. While a few high & mid level clouds are around during the day from that storm passing well to the south, a northerly air flow will bring some ocean cloudiness into portions of southeastern MA today. Sunday’s sky will be cloud-free. The storm track will remain suppressed early next week although a little less so, so the next disturbance in the pipeline will have the chance to get a little bit closer to the region on Tuesday while another trough approaches from the west Tuesday into Wednesday. So far, this period looks more like a cloudier time versus having any significant precipitation, but I’ll keep an eye on it…

TODAY: Partly cloudy except mostly cloudy at times MA South Shore through Cape Cod. Highs 34-41. Wind N 5-15 MPH.

TONIGHT: Clearing. Lows 18-25. Wind N under 10 MPH.

SUNDAY: Sunny. Highs 35-42. Wind NW 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 20-27. Wind W up to 10 MPH.

MONDAY: Partly sunny. Highs 37-44. Wind SW up to 10 MPH.

MONDAY NIGHT: Increasing clouds. Lows 21-28. Wind variable under 10 MPH.

TUESDAY: Cloudy. Highs 35-42. Wind variable up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. Lows 27-34. Wind variable up to 10 MPH.

WEDNESDAY: Mostly cloudy. Highs 37-44. Wind variable 5-15 MPH.

DAYS 6-10 (JANUARY 14-18)

Another disturbance should scoot through from west to east at the same time temperatures moderate but only expecting a rain or snow shower threat for January 15 before a shot of colder air arrives for the MLK Jr Weekend. We may need to watch for a storm system before that weekend is over, but this is a longer range look with low confidence at this time.

DAYS 11-15 (JANUARY 19-23)

A weakening of the blocking pattern is possible. This should allow for another cold shot at some point and at least one precipitation potential.

C-19 Chat Post – January 9 2021

DAYS 1-5 (JANUARY 8-12)

Strong blocking continues, keeping it dry here while the storm track is forced to the south through at least the weekend. The next system may get closer by Tuesday but the evolution and track remain in question.

TODAY: Mostly sunny but some increasing high clouds later in the day. Highs 36-43. Wind variable up to 10 MPH.

TONIGHT: Variably cloudy. Lows 20-27. Wind variable up to 10 MPH.

SATURDAY: Filtered sun with high clouds to start, then brighter sunshine. Highs 34-41. Wind variable to N 5-15 MPH.

SATURDAY NIGHT: Clear. Lows 18-25. Wind N under 10 MPH.

SUNDAY: Sunny. Highs 35-42. Wind NW 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 20-27. Wind W up to 10 MPH.

MONDAY: Mostly sunny. Highs 37-44. Wind SW up to 10 MPH.

MONDAY NIGHT: Increasing clouds. Lows 21-28. Wind variable under 10 MPH.

TUESDAY: Cloudy. Highs 35-42. Wind variable up to 10 MPH.

DAYS 6-10 (JANUARY 13-17)

We will continue in a blocking pattern with active and changeable weather. We’re vulnerable to unsettled weather through January 15 followed by a shot of Arctic air to end the period. as a result of it, starting with a storm threat int he January 12-13 period, depending on how close low pressure from the southwest gets to our area, followed by what looks like a weaker system passing by around January 15 and a shot of arctic air potentially arriving at the end of the period.

DAYS 11-15 (JANUARY 18-22)

Blocking should continue but may weaken. I continue moderately confident of a colder than normal period here but less confident about any storm threats.

C-19 Chat Post – January 8 2021

DAYS 1-5 (JANUARY 7-11)

I’m not going to spend time over-analyzing our blocking pattern or trashing the over-hyped headlines flying around the net. Waste of time, actually. Today, I’ll do what I feel I do best, and that is focus on the weather pattern and its expected impact on the WHW forecast area. So let’s do that. 🙂 Blocking continues and will be on the strong side, forcing a storm to pass south of our area Friday night & Saturday, with us seeing no more than some high clouds from the northern side of its cloud canopy. This leaves us dry and seasonably chilly for the next 5 days with today probably the “mildest” and either Saturday or Sunday the “coldest”. See? That was easy…

TODAY: Partly cloudy. Highs 33-40. Wind variable 5-15 MPH.

TONIGHT: Clear. Lows 18-25. Wind variable up to 10 MPH.

FRIDAY: Mostly sunny but some increasing high clouds later in the day. Highs 36-43. Wind variable up to 10 MPH.

FRIDAY NIGHT: High overcast. Lows 20-27. Wind variable up to 10 MPH.

SATURDAY: Filtered sun with high clouds to start, then brighter sunshine. Highs 34-41. Wind variable to N 5-15 MPH.

SATURDAY NIGHT: Clear. Lows 18-25. Wind N under 10 MPH.

SUNDAY: Sunny. Highs 35-42. Wind NW 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 20-27. Wind W up to 10 MPH.

MONDAY: Mostly sunny. Highs 37-44. Wind SW up to 10 MPH.

DAYS 6-10 (JANUARY 12-16)

This 5-day period is where we will continue in a blocking pattern but likely see more active and changeable weather as a result of it, starting with a storm threat int he January 12-13 period, depending on how close low pressure from the southwest gets to our area, followed by what looks like a weaker system passing by around January 15 and a shot of arctic air potentially arriving at the end of the period.

DAYS 11-15 (JANUARY 17-21)

Blocking should continue. I’m moderately confident of a colder than normal 5-day period here but less confident about any storm threats, leaning drier initially.

C-19 Chat Post – January 7 2021

DAYS 1-5 (JANUARY 6-10)

We now are in a blocking pattern and have seen a stratospheric warming event disrupt the polar vortex which means a more volatile pattern for the Northern Hemisphere. What does that mean for us here in the northeastern US? Well, in the very short term, it doesn’t mean all that much different from what I’d been discussing, regarding getting rid of our offshore storm today, slowly, and seeing the next storm system miss to the south early in the weekend, leaving us with seasonably chilly and generally dry weather.

TODAY: Variably cloudy. Possible passing snow showers except snow or rain showers Cape Cod. Highs 35-42. Wind N-NW 5-15 MPH.

TONIGHT: Clearing. Lows 22-29. Wind NW 5-15 MPH.

THURSDAY: Sunny. Highs 33-40. Wind variable 5-15 MPH.

THURSDAY NIGHT: Clear. Lows 18-25. Wind variable up to 10 MPH.

FRIDAY: Mostly sunny but some increasing high clouds later in the day. Highs 36-43. Wind variable up to 10 MPH.

FRIDAY NIGHT: High overcast. Lows 20-27. Wind variable up to 10 MPH.

SATURDAY: Filtered sun with high clouds to start, then brighter sunshine. Highs 37-44. Wind variable to N 5-15 MPH.

SATURDAY NIGHT: Clear. Lows 18-25. Wind N under 10 MPH.

SUNDAY: Sunny. Highs 36-43. Wind NW 5-15 MPH.

DAYS 6-10 (JANUARY 11-15)

The blocking pattern will remain in place. Various guidance remains in disagreement about how the next storm threat(s) will play out but we need to keep an eye on one or potentially 2 systems (January 12-13 & 14-15). The disruption of the polar jet stream will make it difficult to gauge the evolution and timing of disturbances that have the potential to impact our region. Temperatures overall will not be that far from normal.

DAYS 11-15 (JANUARY 16-20)

Still lower confidence due to the upcoming instability of the large scale pattern. For now holding onto a continuation of and possible start of the breakdown of the blocking set-up but still a volatile pattern with the impacts from an unstable polar vortex. This probably leads to at least one storm threat and with colder air potentially more available, the winter storm threat would be there. Lots to monitor in the days ahead.

C-19 Chat Post – January 6 2021

DAYS 1-5 (JANUARY 5-9)

We continue to watch a blocking pattern establish itself with visible evidence in low pressure temporarily stuck off our eastern coastline, which will continue to through cloudiness and occasional rain & snow showers back into the region, especially eastern areas, through early Wednesday, before it heads out and high pressure takes its place later in the week with seasonably chilly, dry weather. The next storm system will very likely head out to sea south of New England, with our area only seeing some high cloudiness from it later Friday into Saturday. This is due to the block’s positioning and strength and the resulting storm track being forced well to the south. This particular block is also keeping the cold air on the “other side” of the pole, with parts of Asia & Europe much colder while North America is not so cold.

TODAY: Mostly cloudy. Rain/snow showers favoring NH Seacoast, eastern MA, and possibly RI. Highs 32-39. Wind N 5-15 MPH interior except 15-25 MPH eastern coastal areas.

TONIGHT: Mostly cloudy. A few snow showers lingering in eastern areas. Lows 25-32. Wind N 5-15 MPH.

WEDNESDAY: Mostly cloudy early morning with a lingering snow shower possible in eastern areas, then partly sunny. Highs 35-42. Wind N-NW 5-15 MPH.

WEDNESDAY NIGHT: Clearing. Lows 22-29. Wind NW 5-15 MPH.

THURSDAY: Sunny. Highs 33-40. Wind variable 5-15 MPH.

THURSDAY NIGHT: Clear. Lows 18-25. Wind variable up to 10 MPH.

FRIDAY: Mostly sunny but some increasing high clouds later in the day. Highs 36-43. Wind variable up to 10 MPH.

FRIDAY NIGHT: High overcast. Lows 20-27. Wind variable up to 10 MPH.

SATURDAY: Filtered sun with high clouds to start, then brighter sunshine. Highs 37-44. Wind variable to N 5-15 MPH.

DAYS 6-10 (JANUARY 10-14)

The blocking pattern will remain in place. The next storm threat is in the January 12-13 window and this one may get a little closer to the region than the one before it, so we’ll have to keep a close eye on it. Temperatures not too far from normal.

DAYS 11-15 (JANUARY 15-19)

With low to moderate confidence I look for a weak system to pass through with minor precipitation about January 15 and a break-down of the large scale blocking pattern, which for our area probably means dry, colder weather overall. Have to watch for any disturbances from the west that medium range guidance is not picking up on solidly this far in advance.

C-19 Chat Post – January 5 2021

DAYS 1-5 (JANUARY 4-8)

Low pressure southeast of New England will remain just far enough offshore to keep its main precipitation shield, which is over Cape Cod and parts of the South Shore of MA as mainly rain right now, out over the water, but will do a small cyclonic loop east of our region through early Wednesday, keeping lots of cloudiness and a few episodes of rain and snow showers going, mainly for the NH Seacoast region through eastern MA and possibly RI, while areas to the west see cloudiness but probably no precipitation other than a brief snow shower on Tuesday when the low is at its furthest west. The system finally pulls away during Wednesday allowing dry air to move in, which will then dominate through Friday as high pressure moves in and dominates. We will start to see some high cloudiness in the sky on Friday in advance of the next low pressure area we have to watch.

TODAY: Cloudy. Rain Cape Cod and southern South Shore of MA this morning. Isolated to scattered rain and snow showers elsewhere until midday. Highs 34-41. Wind NE to N 5-15 MPH except 10-20 MPH coast.

TONIGHT: Mostly cloudy. Snow showers possible, favoring the capes of MA. Lows 25-32. Wind N to NW 10-20 MPH, higher gusts.

TUESDAY: Mostly cloudy. Rain/snow showers favoring NH Seacoast, eastern MA, and possibly RI. Highs 32-39. Wind N 5-15 MPH interior except 15-25 MPH eastern coastal areas.

TUESDAY NIGHT: Mostly cloudy. A few snow showers lingering in eastern areas. Lows 25-32. Wind N 5-15 MPH.

WEDNESDAY: Mostly cloudy early morning with a lingering snow shower possible in eastern areas, then partly sunny. Highs 35-42. Wind N-NW 5-15 MPH.

WEDNESDAY NIGHT: Clearing. Lows 22-29. Wind NW 5-15 MPH.

THURSDAY: Sunny. Highs 33-40. Wind variable 5-15 MPH.

THURSDAY NIGHT: Clear. Lows 18-25. Wind variable up to 10 MPH.

FRIDAY: Mostly sunny but some increasing high clouds later in the day. Highs 36-43. Wind variable up to 10 MPH.

DAYS 6-10 (JANUARY 9-13)

Blocking pattern in place, may be strong enough to force the next storm system south of the region on January 9 but we’ll have to continue to keep an eye on it. High pressure builds in with fair and seasonably chilly weather January 10-11, then watching the next unsettled weather threat from low pressure heading this way from the southwest January 12-13.

DAYS 11-15 (JANUARY 14-18)

Unsettled weather threat briefly between late January 14 into January 15, but otherwise mainly dry and trending a little colder mid to late period. Large scale blocking pattern may begin to break down during this period.

C-19 Chat Post – January 4 2021

DAYS 1-5 (JANUARY 3-7)

Clouds will be dominant today from a combination of onshore air flow pushing lower level clouds in from the Atlantic, and clouds coming in above that ahead of our next storm system, the center of which will pass just southeast of New England Monday, then do a bit of a loop east of New England for a couple days after that keeping is on the unsettled side here, before high pressure moves in with fair weather for Thursday.

TODAY: Increasing clouds. Snow/mix interior, mix/rain coast, arriving late-day. Highs 35-42. Wind N up to 10 MPH.

TONIGHT: Cloudy. Periods of snow except mix/rain in coastal areas. Lows 30-37. Wind NE 5-15 MPH.

MONDAY: Cloudy. Rain (mostly coast) & snow (mostly interior) tapering off later in the day. Snow accumulation from up to a slushy coating coastal areas, coating to 2 inches I-95 belt and lower I-495 belt, 2-4 inches upper I-495 belt northwestward. Highs 32-39. Wind NE to N 10-20 MPH, higher gusts.

MONDAY NIGHT: Mostly cloudy. Snow showers possible. Lows 25-32. Wind N to NW 10-20 MPH, higher gusts.

TUESDAY THROUGH WEDNESDAY: Variably cloudy. Snow and/or rain showers possible. Temperatures generally 32-39. Wind N to NW 10-20 MPH, higher gusts.

WEDNESDAY NIGHT: Clearing. Lows 22-29. Wind NW 5-15 MPH.

THURSDAY: Sunny. Highs 33-40. Wind variable 5-15 MPH.

DAYS 6-10 (JANUARY 8-12)

A stronger blocking pattern is expected to force the next low pressure area in the pipeline south of New England between late January 8 and early January 10 but we’ll have to keep an eye on it anyway, just in case it ends up further north than expected. The next system may approach by the very end of the period and have a better chance at reaching this area.

DAYS 11-15 (JANUARY 13-17)

Expecting an unsettled start to this period, details dependent on the track of low pressure, and then a shift to seasonably cold and dry weather.
