Woods Hill Weather

10:35PM

A cold front approaches Tuesday, which will be a mild to warm day (cooler South Coast due to wind off water). Rain showers will arrive from the west in the evening, making for a fairly wet night.

Front pushes offshore early Wednesday, which may begin with some showers, as low pressure forms on the front and intensifies while moving away. The balance of the day ends up windy and cooler with breaking clouds. Can’t rule out an additional shower due to some instability.

Thursday will be the brightest day of the week as high pressure moves in from the west, but low pressure to the east will still be close enough to cause a gusty breeze between itself and the approaching high pressure area. It will remain cool.

Late week will see the approach, passage, and departure of a low pressure area, the timing of which remains uncertain. For now, will go for an increase in clouds Friday, wet weather at night, lingering showers into Saturday, then variably cloudy conditions with some lingering threat of showers later Saturday and Sunday. There is conflicting information on whether or not it clears out by next Monday. Will split the difference for now.

This week starts with a very special day in this part of the world. Patriots Day, also the day of the Boston Marathon, is an important day in the Boston area. We have history and tradition. There will be a re-enactment of the battle that started the Revolutionary War in Lexington and Concord MA at dawn. It will be fair and chilly for that with temperatures in the upper 30s under a mostly clear, brightening sky, with light wind. There is, of course, The Boston Marathon, which takes on even more significance this year – one year after the bombing. The weather for this great race will be nearly perfect, cool to mild air, generally light wind, with a bit of a cooling sea breeze near the finish. And don’t forget about the Boston Red Sox, playing their annual late-morning start home game at Fenway Park. It will be a great day for April baseball.

How about the rest of the week? Here’s a quick summary.

A cold front approaches Tuesday, which will be a mild to warm day (cooler South Coast due to wind off water). Rain showers will arrive from the west in the evening, making for a fairly wet night.

Front pushes offshore early Wednesday, which may being with some showers, as low pressure forms on the front and intensifies while moving away. The balance of the day ends up windy and cooler with breaking clouds.

Thursday will likely be the brightest day of the week as high pressure moves in from the west, but low pressure to the east will still be close enough to cause a gusty breeze between itself and the approaching high. Cool air will dominate.

Late week will see the approach, passage, and departure of a low pressure area, the timing of which is uncertain. For now, will go for an increase in clouds Friday, wet weather at night, lingering showers into Saturday, then variably cloudy weather with some lingering threat of showers later Saturday and Sunday.

9:28AM

An east wind off the chilly ocean will make today less mild than yesterday over most of the region, but still a very nice Easter Sunday for those celebrating it, and if you are, I wish you a happy one! High pressure in control will bring plenty of bright sun.

This high holds Monday, which is Patriots Day, or Marathon Monday, and with a more southerly flow it will warm up, especially inland. The wind will be light enough to allow some ocean breezes in coastal areas, and already an onshore flow along the South Coast with the southerly wind, so these areas again will be cooler.

A southwest flow arrives Tuesday ahead of an approaching cold front. Though more clouds are expected, and eventually a shower threat, we’ll see all areas except the South Coast at least in the 60s, with some lower 70s not out of the question.

The front that approaches Tuesday will be slow to move through and will allow low pressure to form on it, keeping Wednesday unsettled and cooler. This low will then intensify and move away slowly, so that Thursday will be a fair but gusty and cool day. The squeeze play will be on Friday between that and another approaching low from the west. Questions arise as to how quickly this low will firstly move in, secondly hang around, and thirdly get the heck out of here. So the later Friday / Saturday forecast is low confidence, and when I put up The Week Ahead post later, we’ll probably add Sunday to the low confidence mix.

7:29AM

An onshore flow from the east will send lots of low clouds from the ocean into southeastern New England today, but an approaching and passing cold front will turn winds around to west by Saturday, with the front bringing only some cloudiness early. The remainder of the weekend which includes Easter Sunday and Patriots Day Monday will be fairly nice as high pressure dominates. Some clouds may start to increase later Monday ahead of the next weather system. This system may impact the region in the Tuesday/Wednesday time frame next week, but does not look too impressive at this time.

7:24AM

High pressure centered over the St. Lawrence Valley will slide eastward through the Canadian Maritime Provinces through Friday. An onshore flow (northeast to east) will dominate through Friday, relaxing later Friday. This will keep the weather fair but cool, though some scattered ocean clouds will visit coastal areas at times today and more so on Friday, starting to increase more later Friday. A pair of low pressure areas, one passing well southeast of New England, and a second  one passing north of the region, will bring some cloudiness into the region for Saturday though these systems will be fairly weak and not interactive with each other, so the chance for any precipitation on Saturday is minimal. High pressure will build across the region Sunday (Easter for many) and Monday (Patriots Day & Boston Marathon) with some great weather – seasonable to mild, coolest along the coast. A low pressure system will approach Tuesday and exit Wednesday with some unsettled weather at that time.

Forecast for southeastern New England…

9:46PM

The summer preview is over.  The warmth of Monday and Tuesday is about to be history. Monday was a generally nice day despite plentiful cloudiness, and Tuesday was mainly cloudy and showery, with heavier showers moving in toward the end of the day for most locations. The problem with both days were strong and gusty southwest to south winds, which resulted in scattered damage and power outages.

A cold front is moving west to east through the region this evening and moisture will continue to flow northward along it, continuing the rain for most areas into the overnight hours. But as cold air works in, we’ll see a mix/change to sleet/snow from west to east, making it just about into the Boston area before the precipitation exits before the line really makes it any further to the southeast. Areas along and west of I-95 may see a coating to locally 1 inch of snow (especially higher elevations). All of this will clear offshore by dawn on Wednesday, which will turn out bright, cool, and windy. High pressure building in will make for a cold Wednesday night / Thursday morning as winds drop off under a clear sky. Thursday will continue to be cool, though the sun will feel nice, since there will be less wind. High pressure will hang on Friday which will start sunny but it will start to lose grip later in the day when clouds begin to increase.

Looking ahead to the weekend, which includes Easter for many, and is a long weekend as well for some as Monday is Patriots Day or Marathon Monday, it looks like low pressure will pass through the region Saturday with some wet weather, and may be fast enough that we start to clear late. Sunday looks mostly fair but some gusty wind and areas of clouds may be a factor as low pressure intensifies while moving away and cold air aloft allows clouds to pop up. Monday should start sunny but end with increasing clouds as high pressure tries to hold off approaching low pressure. That area of low pressure will get closer Tuesday which should turn cloudy with eventual wet weather arriving.

Forecast for southeastern New England…

OVERNIGHT: Cloudy with rain then a mix/change to sleet/snow from west to east from around midnight to around 5AM from west of I-95 into the I-95 corridor, but precipitation ending before changing over in southeastern MA. Snow accumulation of a coating to locally 1 inch where a changeover occurs. Lows by morning upper 20s hilly areas of north central MA and south central NH, 30s elsewhere. Wind W 10-20 MPH with higher gusts.

WEDNESDAY: Clearing at dawn, then mostly sunny. Highs middle 40s to around 50. Wind NW 15-25 MPH with higher gusts.

WEDNESDAY NIGHT: Clear. Lows from the lower 20s inland valleys to middle 30s immediate coast and urban centers. Wind light N.

THURSDAY: Mostly sunny – few high clouds. Highs around 50. Wind light N to NE.

FRIDAY: Mostly sunny but more clouds late day. Low 35. High 53.

SATURDAY: Mostly cloudy with rain showers, ending late. Low 41. High 54.

SUNDAY: Mostly sunny morning, partly sunny afternoon. Low 40. High 59.

MONDAY: Partly sunny. Low 44. High 61.

TUESDAY: Cloudy. Afternoon rain showers. Low 48. High 55.

Some of you were nervous, weren’t you?  You saw clouds and showers around Sunday morning and you thought “it’s not going to warm up, it’s going to stay lousy”. Weather changes often, and these changes are often marked by unsettled conditions. This is what happened Sunday morning – clouds and showers ahead of and along an advancing warm front.  It took a while, especially in east coastal New England, but the front has finally pushed through the region and some clearing did work in from the west with most areas seeing some sunshine before its after-7PM setting. And now it’s time to look ahead…

This coming week, typical of April, will feature some good contrasts. It will start with a summer preview Monday as a very warm southwesterly flow dominates the region ahead of a cold front west of the region. There will be an exception though, and that is where the southwest wind is coming off the Atlantic waters, keeping the South Coast of New England and southeastern MA considerably cooler. In fact there will be quite a temperature contrast from those ocean-cooled areas to the warmest zones, inland valleys well west and north of Boston. There should be plenty of sun as well. Clouds will start to increase at night from west to east as a strong but slow moving cold front from the west begins to push toward the region. It will likely take all day Tuesday and into early Wednesday for this front to transverse the region. It will be a slow west-to-east process, starting mostly  Tuesday afternoon and ending Wednesday morning. Despite the summertime temperatures readings expected on Monday in parts of the region, much colder air lurking on the other side of the approaching front, once it gets in here, may result in some locations flipping to snow before ending. In fact the areas that are the warmest Monday will have the greatest chance of flipping to snow early Wednesday. Once that fanfare is done, look for a quieter but chilly mid week as high pressure builds in. Fair weather should last through most of Friday, but the next low pressure area approaching from the southwest may spread clouds into the region before the day is over. It is a little far ahead, obviously, but I expect that system to be progressive and move through rather quickly during the first part of the weekend, when unsettled weather is expected. Improving weather would then likely follow on Sunday, which is Easter for those who celebrate it.

Southeastern New England Forecast…

OVERNIGHT: Partly to mostly cloudy. Patchy fog late. Lows upper 40s to middle 50s. Wind SW 5-15 MPH.

MONDAY: Patchy fog early. Partly to mostly sunny. Highs ranging from the upper 50s immediate South Coast, Cape Cod, and Islands to the 70s most of interior eastern MA and southern NH, some lower 80s possible interior valleys well west and north of  Boston.  Wind SW 10-20 MPH gusting to around 30 MPH.

MONDAY NIGHT: Increasing clouds west to east. Lows in the 50s. Wind SW to S 10-20 MPH with higher gusts.

TUESDAY: Mostly cloudy. Numerous showers developing west to east midday on, may take a while to reach all eastern areas. Highs in the 60s except 50s South Coast. Wind S 15-25 MPH and gusty.

WEDNESDAY: Chance of rain and snow showers very early followed by clearing. Low 33. High 48.

THURSDAY: Mostly sunny. Low 32. High 52.

FRIDAY: Sunshine then increasing clouds late. Low 35. High 56.

SATURDAY: Cloudy with a chance of rain. Low 40. High 50.

SUNDAY: Clearing. Low 45. High 60.

7:44PM

Another day of fairly mild to warm temperatures on Friday – even warmer than I expected, with some locations hitting or exceeding 70, especially interior eastern MA to southern NH. A cold front has been working into the region from the northwest, but slowly, causing lots of clouds and some rain shower activity. This will continue through the night as a little wave of low pressure moves along the front, but also serves to pull it further to the south as it passes. This will allow somewhat cooler air to settle in through Saturday morning, along with lots of clouds, before drier air returns sunshine to the region and allows temperatures to warm up in the afternoon, except along the coast and over Cape Cod where it will be cooler due to the ocean’s influence. A warm front will cross the region eraly Sunday with some clouds and maybe a shower in parts of far northern MA and southern NH, otherwise sunshine will end up ruling Sunday along with slightly warmer air. This warm air will max out over the region Monday, with a late Spring / early Summer feel to the air thanks to a strong southwesterly flow ahead of an approaching cold front. The exceptions both Sunday and Monday will be the South Coast and Cape Cod where south to southwest winds come across somewhat cooler waters and modify the temperatures there. Once we get to the Tuesday-Thursday period of next week, a transition will take place as a cold front ambles west to east across the region Tuesday with wet weather developing as mild air hangs on. How quickly midweek clearing comes will be dependent on the speed of the front and the push of a new high pressure area from Canada, so Wednesday’s forecast is low confidence. Thursday should be dry but fairly chilly.

Southeastern New England Forecast…

TONIGHT: Mostly cloudy. Periods of rain showers. Lows in the 40s. Wind N 5-15 MPH.

SATURDAY: Lots of clouds to start out the day transitioning to lots of sun to finish it. Highs in the 60s, except 50s Cape Cod and falling into the 50s coastal areas afternoon. Wind N to variable up to 10 MPH with afternoon sea breezes likely.

SATURDAY NIGHT: Partly cloudy. Lows in the 40s. Wind light SE.

SUNDAY: Variably cloudy with a risk of a shower northern MA and southern NH in the morning, otherwise partly cloudy to mostly sunny. Highs in the 60s most locations, except upper 50s South Coast and Cape Cod and lower 70s interior valleys MA and southern NH. Wind S 10-15 MPH.

MONDAY: Mostly sunny to partly cloudy. Lows in the 50s. Highs upper 50s Cape Cod ranging to the lower 80s interior valleys of MA and southern NH.

TUESDAY: Mostly cloudy. Rain showers developing west to east, becoming numerous. Lows in the 50s. Highs in the 60s.

WEDNESDAY: Mostly cloudy to partly sunny. Lows in the 30s. Highs around 50.

THURSDAY: Mostly sunny. Lows upper 20s to lower 30s. Highs in the 40s.

FRIDAY: Increasing clouds. Lows in the 30s. Highs in the 50s.

7:07AM

A big diurnal today for many areas. What’s a diurnal? In weather we use it to label the change in temperature from morning low to afternoon high. Today, some places that dipped into the upper 20s this morning will rebound to the lower 60s this afternoon – about a 40 degree diurnal.

Nothing major to change in this forecast from the previous one, other than to keep it a little more cloudy on Friday as a cold front sags through the region and hangs up near the South Coast. Once low pressure rides along this with a shot of wet weather Friday night and early Saturday, the rest of the weekend will be dry. Still looks like clouds arrive later Sunday ahead of a warm front which leads in a warm/windy air mass for Monday. Transition back to cooler air toward the middle of next week will likely result in some wet weather. But it all starts off with a bright day today (until clouds arrive late) with a gusty wind developing as milder air arrives.

Southeastern New England Forecast…

TODAY: Sunny most of day, increasing high clouds late. Highs 60-65, 50s South Coast. Wind SW under 10 MPH early then increasing to 10-20 mph with higher gusts.

WEDNESDAY: Mostly cloudy to partly sunny. Low 35. High 55.

12:59AM

This is that time of year that the sun is really making a difference. We have a fresh cool air mass now over southeastern New England, and the temperatures will be at least 10 degrees cooler in most areas today than they were on Tuesday. But the strong April sunshine will make the air feel warmer than it is, especially since it will be a west wind and not a widespread ocean wind (a west wind does still come off the ocean for parts of the South Coast so it will be cooler there). Some fair weather clouds will pop up from late morning into afternoon as sun hearing the ground will send some bubbles of moisture into the cold air aloft.  The cooler northwest wind of today will shift around to the southwest and start to warm things up on Thursday, with sunshine dominating, though some high clouds may start to increase in the afternoon ahead of an approaching cold front. This front will be moving along initially and will pass through the region by early Friday morning, bringing clouds and a risk of a few rain showers. It should push just far enough to allow some partial clearing into at least areas north and west of Boston on Friday while clouds hang on to the southeast. Clouds will likely return to all areas Friday night and Saturday morning, with perhaps some wet weather, as a wave of low pressure slides along the front nearby. Then, high pressure should push in for drier weather later Saturday and Sunday. A warm front will push through the region late Sunday and open the door for a much warmer shot of air at the beginning of next week.  This should be accompanied by fair weather but gusty winds on Monday, but clouds and showers may arrive Tuesday as yet another cold front approaches from the west.
