Steadier Rain Coming Thursday, Moderate Gusts Possible

For the fourth day in a row, we start off with cloudy skies and damp weather.

Temperatures are on the chilly side: 40s and 50s, a little bit above the climatological average for Oct. 30, but jacket weather nonetheless. High pressure in the Gulf of Maine has not helped to clean out the low level thermal inversion and clouds.

There’s even a little bit of a low-pressure system south of Nantucket Wednesday morning, a bit of remnant of that Sunday storm that sat there and lingered. Clouds will stay fairly thick in southern New England with a chance of heavy drizzle and then just plain rain showers by this afternoon.

High temperatures Wednesday will be in the 50s and 60s, with wind from the southeast gusting at 10 to 15 mph.

The biggest feature on the national weather map is an unusually strong high-pressure system from the north pole that moved into the Rockies. It is responsible for strong wind in California Wednesday, and also extremely cold weather and snow in much of the central part of the nation.

A weak low-pressure system is being fueled by moisture from the Gulf of Mexico coming up the Mississippi Valley in the south eastern United States.

That steadier rain will be arriving Thursday, but it’s still a tough call for how much rain trick-or-treaters will face. A lot of towns have already postponed trick-or-treating to the weekend, based on the possibility of downpours and strong wind.

Clouds with drizzle and fog will remain Wednesday night, with low temperature in the 50s, even rising into the 60s in spots.

Wind will increase from the south during the day Thursday with showers becoming steadier and heavier. Temperatures will be rising through the 60s much of southern New England, and at least to near 60 degrees north.

The warmest weather actually happens overnight Thursday with downpours and high humidity. Wind from the south may gust over 40 mph with temperatures holding in the 60s to low 70s, Record high temperatures are possible in the overnight time period.

Low pressure will pass north of New England early on Friday morning, with a powerful cold front moving across the region. We may have downpours within thunder around sunrise, winds possibly gusting over 50 mph and temperatures near 70 degrees. Rainfall of 1 to 3 inches possible.

By lunchtime, we have drier wind from the west, still gusting to near 50 mph with temperatures falling through the 60s, 50s, into the 40s for many of us by sunset Friday.

High pressure comes in Saturday with fair weather and temperatures in the 40s north, and 50s south.

An upper level low pressure system may bring clouds in on Sunday with a chance of some higher elevation mixed showers of rain and snow. Temperatures again in the 40s and 50s.

Monday looks seasonable and quiet. Election Day Tuesday may feature showers, temperatures likely in the 50s. At this point it does not look like a big storm, but much colder air will be working in the second half of next week- as seen here in our First Alert 10-Day Forecast.
