The weekend is shaping up to be an unsettled one with a sizable amount of rain, wind and possible record warmth all in one.
On Friday morning, we find a cool, somewhat moist flow of air over southern New England. Temperatures earlier Friday morning were almost 40 near the water, down to the teens inland. This wide range of temperatures will even out later Friday and hit the upper 30s. There is a deck of clouds over the region today, but other than some patchy drizzle late, there won’t be any precipitation.
Friday night into Saturday, there’s a slight chance of incredibly light, almost unnoticeable freezing drizzle or snow. The only reason I even mention it is because the north and west of Boston may have slick walkways Saturday morning, so just give a quick check before you step out.
The bulk of Saturday is dry, cool and cloudy. We’ll have to wait until Sunday before a batch of heavy rain moves north. On Sunday, a large storm system is going to pass to the west. When storms move west of New England, they bring warm air north on their right side. On Sunday, temperatures will surge into the 50s south of the Massachusetts Turnpike and into the 40s north. On Sunday, the record high in Boston is 56, and there’s an outside chance we could tie it, but it’s more likely we fall short by a few degrees.
The map below shows how much above or below average the temperature will be on Sunday. Notice the all the warmth over our area and the cold in the Midwest. Temperatures in New England may be as much as 20 degrees above average.
The weather map for Sunday shows the heavy rain in place. The rain will begin early in the day and there will likely be some street flooding in poor drainage areas. Winds will also be noticeable, gusting over 30 miles per hour at times. Even the rumble of thunder isn’t out of the question as the storm system passes by Sunday afternoon.
Heavy Rain on Sunday
I am expecting a significant rain event. It’s a good thing we don’t have lots of snow piled up on the roofs around here or we’d be facing that type of issue. The map below is an average rainfall forecast from the models. It appears likely we will all receive around an inch, but 2 inches isn’t impossible in a heavier thunderstorm and a bit under can always happen.
Colder and drier weather returns to start the new work week, but the overall pattern is definitely more active, so expect a changeable forecast for the next couple of weeks.
