Forecast: After Mild Start, Week Could End With Light Snow

This article is more than 5 years old.

Enjoy the mild air the next couple of days because a big shift in temperatures is looming on the horizon. Highs this time of year should still be getting into the upper 50s to even around 60.

Today we will be in the upper 60s to near 70 and likely as warm if not a few degrees warmer tomorrow. Then the temperature begins to drop on Thursday as colder and drier air filters in. By Friday we lose a few more degrees with highs by then only in the lower 50s, but at least there will be a lot of sunshine.

Anytime we have snow in the forecast there starts to be all sorts of wild forecasts as to what might happen. On Friday night a low pressure area to our west will begin to transfer its energy to the coast and form a new storm.

This new low-pressure system will develop and have with it quite a bit of rain and even snow.

The big question becomes how close to the coast does this storm come and what is the timing of the system. Currently some rain is likely to fall Saturday and may end as a period of snow showers or light snow Saturday night and Sunday morning.

There is also an equal likelihood right now that the storm moves too far north and east before it develops so that we end up dry, windy and cold by Sunday morning after a short period of rain Halloween evening and night.

What is a sure bet is the cold and highs on Sunday will be more typical for early December, not the first of November. If you haven’t brought out the winter-weight coats and blankets, it’s time.

The forecast is going to change quite a bit over the next three days so check my updates on Twitter and look for a new forecast each day here.


Tuesday: Mostly sunny and mild with highs of 65 to 70.

Tuesday night: Partly cloudy and not so cold with lows in the 50s.

Wednesday: Lots of clouds with some breaks of sun. A few midday showers or thunderstorms between noon and 5 p.m. (earliest to the west; latest on Cape Cod). Highs of 65 to 72.

Thursday: Mostly sunny and cooler with highs in the mid 50s.

Friday: Partly sunny with highs of 50 to 55.

Saturday: A chance of rain. It will be very raw and chilly. Highs of 40 to 45.
