Well, it was nice while it lasted. 2 days with temps in the 70′s has some of us longing for the days of summer to return again..but that is just a dream. The cool feel of fall has returned and it will stick around for much of this week.
A beautiful morning across Eastern MA with sunshine and cool crisp temps in the 40′s. Clouds are streaming up the coast with a SW flow aloft with a broad trough in place across the Great Lakes. A vigorous shortwave will track from the Mid-Atlantic up the Hudson Valley this afternoon. Clouds will be spreading from west to east during the day and thicken along with approaching showers from the Mid-Atlantic. Showers should begin to develop in the mid-afternoon between 2-4. Temps will climb into the mid-upper 50′s before the showers arrive. Once the rain starts to fall, look for temps to quickly fall into the 40′s…making for a very cool raw autumn rain. It appears the heaviest of the rain will likely fall in Southeast MA where about a half inch or more of rain could fall. There will be lighter amounts NW of Boston. Showers will become more widespread during the evening hours. Showers will begin to wind down after midnight as an area of low pressure tracks off the coast and begins to pull away. Cold air will follow in behind departing showers with rain changing to snow showers in the NW higher terrain above 2,000 ft of the Green & White mountains where we could pick up a few inches of snow on the mountain tops.
Drying NW winds with building high pressure settles in for Columbus day with bright sunshine, and fair weather clouds with highs remaining in the 50′s I think we will see a brighter day across Northern New England, as high clouds will be streaming north into SNE during the afternoon. This will make for a more filtered appearance to the sky. The clouds are along with another low which will be moving up the coast along this stalled boundary off our coastline. Clouds will thicken Monday night, with the chance of showers reaching Southeast MA by dawn Tuesday morning. East winds with cloud damp conditions will likely keep temps in the 50′s with slightly brighter and warmer conditions in the North and West. Considerable clouds will likely persist through the midweek.
A cold front will sweep into New England Wednesday with the risk of a passing PM Shower. Temps will warm into the mid 60′s with SW winds ahead of the front. A very short-lived warm up. Cooler, dry air returns for Thursday with NW winds with temps in the 50′s and Lwr 60′s with brighter sunshine. Another weak frontal passage for Friday with building cool Canadian High pressure for Saturday with temps remaining in the 50′s.
