    Heaviest Rain Expected Halloween Night

    Today (Tuesday): AM drizzle, then mostly cloudy with sprinkles. Highs in the 50s. Overnight Tuesday Night: Scattered showers. Lows in the 50s. Wednesday: Pockets of showers and light rain. Highs in the lower 60s. (Published Tuesday, Oct. 29, 2019)

    Though the barometer says high pressure, it doesn’t look that way in our weather.

    Sunday’s heavy rain and wind moved away but left behind low-level moisture and thermal inversion. With not too much wind again Tuesday, it’s going to be tough to scour out these low clouds.

    Tuesday morning starts off gray and chilly with spots of fog and drizzle. It’s definitely jacket weather, and a hat and gloves are probably helpful, too. There may be a few breaks of sunshine, including in eastern Massachusetts and Cape Cod, where the wind is still off the water a bit. It’s a rather unusual event to see drier air coming off the ocean, but it may happen.

    For most of us, we may stay gray with patches of drizzle, and little wind. High temperature will be in the 50s to low 60s. Well to our west, there’s another major snowstorm impacting the Rockies, that will move into the central Plains, possibly as a blizzard. And on the West Coast, high winds are fueling fires that continue to burn out of control in California.

    The only advisory in New England right now is for possible splash over with minor high tide flooding again in the middle of the day. The new moon is only about 224,000 miles away from earth, and lined up with the sun, is called a spring tide.

    Little change is expected Tuesday night as we anticipate patchy fog and drizzle, with mostly cloudy skies. Temps will be in the low in the 40s and 50s.

    Wednesday, there’s a chance we have bigger breaks in the cloud cover, but also the development of showers in the afternoon. High temperature will be in the 60s.

    The storm that’s causing the heavy snow in the middle of the nation is going to become a warmer storm for us, with rain becoming possibly heavy at times Thursday afternoon and overnight. The temperature will rise into the 60s for many of us, making for nice temperature to trick-or-treat, but there may be some heavy rain to go along.

    Wind will be increasing from the south, perhaps gusting 30 to 50 miles an hour Thursday night and early Friday morning. We have issued a First Alert for this wind and rain Thursday & Friday.

    A cold front passes Thursday night and early Friday, resulting in much drier weather. The dewpoint will be in the 60s, falling into the 30s during the day with the wind gusting 25 to 35 mph from the northwest. We will have partial sunshine with temperatures in the 60s early, falling to the 50s late.

    The weekend is looking good -- plenty of sunshine and seasonable. The only exception may be in the mountains, where we have some upslope clouds and possibly another coating of snow in the higher summits for our Saturday morning.

    Otherwise, the weekend looks mostly sunny with temperatures in the 40s and 50s by day, and 20s and 30s at night. It’s going to be some of the coldest weather so far this season, as seen here in our First Alert 10-Day Forecast.
