Light showers moved across the area during the pre dawn hours and are now moving offshore at mid morning. A cold front moves through today bringing another push of cold air behind it. Early cloudiness will give way to partly cloudy skies, breezy and cool conditions for Sunday. High temperatures in the mid 50s and west winds that may gust to near 20 mph this afternoon.
A ridge of high pressure begins to nudge into southern New England overnight. With clearing skies overnight we will see a good amount of radiational cooling sending temperatures into the mid to upper 20s inland to the low 30s on the coast. Breezy in the evening but winds quickly drop off to less than 10 mph overnight.
Another in a series of cold fronts approaches early Monday and moves through later in the day. This front will be moisture starved, as so many of them have been in recent weeks. Partly cloudy skies, becoming mostly cloudy for a time with the frontal passage. After a cold start to the day temperatures return to the 50s during the afternoon. Once again the winds will kick up and gust to near 25 mph from the southwest then west.
With colder air taking hold in the wake of the front expect temperatures to take a nosedive Monday night into the 20s just about everywhere, perhaps low 30s in and around the immediate Boston area, with fair skies. Northwest winds diminish to 5 mph or less.
A colder start on Tuesday morning and overall it will be a colder day than Monday. Despite a good amount of sunshine high temperatures only reach the upper 40s to 50 degrees. Light winds.
Tuesday night and Wednesday will see an increase in clouds as a weak cold front approaches with an area of disturbed weather. However, it appears we will remain dry as high pressure shifts offshore. With the high offshore we get into a return flow of milder south to southwest winds by Thursday. Lows Tuesday night and Wednesday night not so cold, generally in the 30s. Another chilly day follows Wednesday, with lots of clouds in place, highs in the upper 40s to low 50s.
Thursday looks dry with a fair amount of sunshine as high pressure remains offshore. Temperatures climb well into the 50s. However, a storm system in the central Plains will be tracking toward southeast Canada. Initially, the attendant warm front pushes through Friday, followed by a cold front by the weekend. At this time the consensus between many of the computer models is for a period of showers Friday into Friday night along with milder temperatures and gusty winds. Halloween evening should be dry as clouds increase overhead, but any precipitation looks to hold off until much later at night or Friday. A milder night Thursday night as well, with lows only near 50 degrees, then climbing into the 60s on Friday.
