October has been a very dry month with barely over a ½ inch of rain so far in Boston. It is destined to be one of the top ten driest Octobers on record. However, with a few light showers around this morning and a more widespread and heavier event Halloween night we will close out the month on the wet side.
Today we start off with chilly temperatures once again with a few light showers and or some steady light rain through northeast Massachusetts. At mid morning the mercury was hovering in the upper 30s to low 40s making for a chilly rain. A mid level disturbance is sliding through the area this morning and is responsible for the unsettled conditions. The light precipitation will come to an end from west to east later this morning. Skies will remain mostly cloudy for a good portion of the day with some late day breaks developing before the sun sets. Highs in the low 50s with a west wind 10 mph or less.
High pressure remains in control at the surface Wednesday night and then begins to move offshore Thursday. Mainly partly cloudy skies tonight, not as chilly with lows in the upper 30s to the low 40s. Winds near calm.
Thursday, as the high moves eastward and well offshore a vigorous storm system will be taking shape through the central portion of the country with precipitation falling from the Great Lakes all the way to the Gulf coast. This storm will be a major player for us Thursday night and Friday and will be centered just north of the Great Lakes Friday then sweeping into eastern Canada over the weekend. It will bring milder air up the coast, showers with periods of heavy rain and lots of wind Thursday night into Friday, followed by blustery and mostly cloudy conditions to start the weekend. A few showers may linger into Saturday as an upper level low remains in the area.
Although Thursday may start out with periods of sunshine it will cloud up quickly and there is a chance of a few showers in the afternoon. Conditions worsen overnight as steadier and heavier rain overspreads the area. Winds will also ramp up as they gust to around 30 mph from the southwest. Milder, highs in the low 60s, overnight lows near steady in the upper 50s.
Friday, rain tapers to showers by late in the day and it will be unseasonably mild. Highs in the upper 60s to low 70s for the first day of November. Gusty southwest winds that could approach 45 mph in the afternoon. A few showers at night, cooler as lows fall into the mid 40s to about 50 degrees.
It remains mild on Saturday, highs rebounding to the low 60s, with plenty of clouds around and a chance of a passing shower. Lows overnight in the 40s.
After a sharp cold front moves through the area it will leave Sunday with gusty winds, much cooler temperatures and partly cloudy skies. Highs only in the upper 40s to low 50s.
