Wednesday March 24 2021 Forecast (7:27AM)

DAYS 1-5 (MARCH 24-28)

Our stretch of pleasant days is behind us and now it’s time for some of the unsettled weather that spring is also known for. One low pressure that has been hanging around the US Southeast Coast is lifting out to the northeast now and will add a little bit of its moisture and air flow to our atmosphere ahead of a warm front, which is parented by a stronger low pressure area heading east northeastward from the Great Lakes to the St. Lawrence Valley, passing well north of our area through Thursday. First, the southern low / warm front combo will increase the cloudiness today and lead to a period of rain later this evening. The weakness of the low and its progression will allow the warm front to make it through, and put us nicely into the warm sector behind it on Thursday. The cold front trailing from the St. Lawrence Valley low leads to another low pressure area that will be intensifying as it heads into the Great Lakes. This will keep us in the warm air into Friday morning when a cold front trailing from the Great Lakes low will come through – rain showers ahead of it, drying behind it during Friday, although that will still be a fairly mild day as, typically for our area, the colder air will wait until a secondary trough passes through to really get into the region Friday night. This sets up a cooler and breezy but dry day Saturday between that departing low (which also exits via the St. Lawrence Valley / Canadian Maritimes) and high pressure in the Great Lakes. This high will come eastward across the region allowing for a chilly Saturday night, which probably would end up even colder if not for increasing clouds ahead of the next low pressure area. This low will also travel through the Great Lakes and pass north of our area, but will be an occluding system and moving fairly quickly, likely to bring wet weather back for a short but notable visit during Sunday. Weekend or not, we do need rain.

TODAY: Patchy fog early morning. Partial sun then becoming cloudy. Highs 49-56, coolest coast. Wind SE 5-15 MPH.

TONIGHT: Mostly cloudy. Periods of rain mid evening through overnight. Lows 41-48. Wind SE up to 10 MPH shifting to SW.

THURSDAY: Lingering rain or drizzle with patchy fog possible early morning, otherwise cloudy to start then increasing sun southwest to northeast, but clouds may linger near the South Coast and Cape Cod. Highs 49-54 Islands / Cape Cod, 57-64 remainder of South Coast, 65-72 elsewhere. Wind SW 5-15 MPH, higher gusts.

THURSDAY NIGHT: Partly cloudy evening. Cloudy overnight with rain showers arriving. Lows 48-55. SW 5-15 MPH, higher gusts.

FRIDAY: Cloudy with areas of fog and rain showers likely until mid morning, then mostly to variably cloudy with a passing rain shower possible. Highs 48-55 Islands & Cape Cod, 56-63 remainder of South Coast and southeastern MA as well Cape Ann, 63-70 elsewhere. Wind S 10-20 MPH with gusts 25-35 MPH shifting to W.

FRIDAY NIGHT: Variably cloudy with a possible rain shower early, then clearing. Lows 38-45. Wind W 15-25 MPH with higher gusts, shifting to NW.

SATURDAY: Sun and passing clouds. Highs 53-60. Wind NW 10-20 MPH, diminishing.

SATURDAY NIGHT: Increasing high clouds. Lows 35-42. Wind variable up to 10 MPH.

SUNDAY: Cloudy. Rain likely midday-afternoon. Highs 46-53. Wind SE 10-20 MPH, higher gusts, shifting to W late.

DAYS 6-10 (MARCH 29 – APRIL 2)

Windy/colder possible rain or snow showers March 29 in the wake of intensifying but departing low pressure. High pressure moves in with fair weather for the last 2 days of March, starting chilly then moderating. Uncertainty to start April but a slower-moving frontal system may bring unsettled weather at some point during the first 2 days of the new month.

DAYS 11-15 (APRIL 3-7)

Confidence lowers this far out but high pressure should be in control with fair weather and a warming trend to start, followed by unsettled and cooling weather.

    1. Temperatures definitely overachieved today. I’ve been going above the models on my forecasts, and I still was about 5 degrees too cool today in most spots.

      With any sunshine tomorrow, I wouldn’t be surprised if we see lots places jump into the middle to perhaps upper 70s.

    2. Yeah that didn’t work out so good. Oh well. Not enough umph to the onshore flow & definitely thinner overcast than I expected up to this point in the day. That’ll change soon but the forecast damage is done. At least people got to enjoy milder air than what was expected. 🙂

  1. Meanwhile, halfway around the world it reached 111 in Kuwait City today. West winds of 20-30 mph all day long resulted in a sandstorm that dropped visibility below a mile at times. Dewpoints were only in the 30s.

    1. I spent a few springs and summers over my 25 year career in Qatar and UAE. The extreme heat and very dry air created living hell when the winds picked up. My first deployment to Qatar in 2003 we had several sandstorms the first couple of weeks. I couldn’t see the waves of F-16’s taking off while on the flight line but you could hear and feel them lifting off with afterburner. Temps exceeded 120 on the flight line with high winds would make the dust become caked to your lips and around your eyes. Brutal! Although, when the wind slacked to barely a breeze in the evening, it created the most incredible sunsets on earth. The wind would then pick up as a “sea breeze” overnight bringing extremely humid air off of the gulf. Then at 6 am it would switch back to a hot land breeze and start the whole thing over again. Now that place is true “ground hog day”! Your post reminds of those days and I will never forget my summer of 2003.

      1. Diamond …there really are no words that can express how grateful I am…we all are….for your service. I thought of cousins when I read the comment you are replying to. Their words mirrored yours. You are the very best part of our country.
