Forecast: More Mild Air This Week Along With Some Periods Of Showers

The big story this weekend was the warmth that spread across much of the eastern half of the United States. Although this morning is cool and raw, warmer air is streaming north and will be here this afternoon and sticking around until Tuesday.

A front ushered in cooler ocean air yesterday, and the further north you were, the cooler it was outside. However, that same front is swinging back around and heading north this afternoon. This means we will flip the other side of the front and temperatures will become spring-like again.

When we have these transitions between cool and mild air, showers are common. I am expecting a period of showers overnight, but things should stay dry except for a bit of drizzle or a few raindrops during both the morning and evening commutes.

The radar image below shows how the radar will look around 11 p.m this evening. I circled the heaviest area of rain which will be to the west of Boston. The rain will likely continue on and off overnight.

Most areas should see a 1/4 to 3/4 of an inch of rain, and we should be happy for anything we get as we have experienced one of the driest years ever recorded in Boston.

Tomorrow will start cloudy, and there could be some wet roads for the early commute. However, it will then turn balmy with sunshine and breezy conditions. Highs will again reach near or exceed 60 degrees --- weather that is far more typical for mid-October or the later half of April, not 10 days before Christmas Eve.

Cooler, but not cold weather arrives the rest of the week with more rain possible on Thursday. It will much colder this coming weekend.
