Big changes are coming this week…Monday will be cool and dry followed by a Tuesday through Friday stretch of much warmer weather.  We’re going to concentrate on Monday with this blog post, but you can get the full 7 Day Futurecast here;

A batch of cold air will be moving over New England through Monday.  You can actually make out the disturbance high above in the atmosphere by looking at the water vapor imagery (below).  This disturbance is called an upper-level low.  These features can linger over an area for days creating unsettled weather for a week at a time.  This upper-level low will be scooting out of here pretty quickly.

Monday will start out with lots of clouds in place (but also some sun).  There could be a stray shower or two for the morning commute, but in general, the AM commute will be dry.

An occasional shower is possible through the morning and through lunch time on Monday.  It’s going to be fairly chilly, too, as temperatures will only rise into the upper 40s by noon.

There could be a few peeks of sun from time-to-time Monday morning and into the afternoon, but this will only create more of an unsettled atmosphere.  Any warming from the sun will allow clouds to more readily billow up in the cold air above.

Showers are expected to become more widespread Monday afternoon.  In fact, the best chances for showers will be between 2 and 6PM.

At 3PM, scattered showers will be around.  They won’t last terribly long, but they could be briefly heavy.

If we get enough sunshine, it’s possible we could get a rumble of thunder Monday afternoon with maybe some small hail.

Rain showers will continue into the evening commute on Monday, and they could be fairly widespread as depicted by the computer model output below.

We certainly won’t see a big warm up Monday afternoon.  Temperatures will likely only hit the lwo 50s at best.

The chance for showers will quickly drop after sunset, as we lose any daytime heating.

That upper-level disturbance moves away from New England on Tuesday and warmer, brighter and drier weather will take over for the rest of the week!
