Forecast discussion: A high pressure ridge over the Atlantic brought us the clear skies during Wednesday morning. However, if you looked outside, you will notice mostly cloudy skies taking over the sky. A cold front over the Mid-Atlantic is going to bring widespread showers and isolated thunderstorms into New England by 6 p.m. Looking at the latest radar image, some heavier rainfall is coming down on a line from Torrington, CT down into Bridgeport.
The precipitation will last through the night, but the thunderstorms will dissipate before midnight. By Thursday morning, we will see some partial sunshine, but colder air behind the front will keep our high temperatures only in the lower 50’s. A weak disturbance behind the front may create some isolated showers after 8 p.m. tomorrow night. But, high pressure behind the disturbance will bring drier air to Southern New England by early Friday morning.
Unfortunately, an upper level low over eastern Canada will continue to bring colder air down into New England. Temperatures will remain below normal right through the weekend. However, high temperatures will slowly warm up, reaching the upper 50’s by Sunday.
As we head back to school on Monday, a low pressure system stalled over Maine will bring the risk of some isolated showers. The low will slowly move out to sea, but it will continue to give us the risk of isolated showers into Tuesday evening. We will return to seeing sunshine by next Wednesday, as a high pressure ridge tries to influence our weather. Temperatures will still be about 7-9 degrees below normal as we head to the end of April.
