The stationary front that was south of the New England south coast all weekend has begun to lift northward as a warm front and was draped across southern New England at mid morning. To the north of the front we are dealing with fog, drizzle and spotty showers and to the south of the front much warmer and humid conditions are developing. The front will slowly lift through the Boston area and points north and west during midday and we are expected see pockets of sun, warm, humid and windy conditions this afternoon.
A cold front moves through later tonight, probably around midnight here in northeast Massachusetts and will be offshore by Tuesday morning. High pressure follows and gives the area another period of delightful weather mid to late week. An offshore storm may threaten us with rain and wind late week or next weekend but there are too many uncertainties this far out.
Today, the morning drizzle and fog lifts and there is a chance of a period of sun with still a chance of showers and possibly a thunderstorm this afternoon. It becomes warm and humid with highs reaching into the mid 70s. The light winds of this morning will scream out of the south during the mid and late afternoon hours, gusting to near 40 mph at times, possibly higher. Gusts that high will bring down small branches, possibly small trees and that could lead to a few power outages.
Tonight, with the approaching cold front we can expect showers and possibly a thunderstorm through the evening and early overnight hours. Some locally heavy downpours are possible. Partial clearing late. Lows falling into the 50s. Gusty southwest winds will shift to the west at 8 to 18 mph after midnight.
Tuesday, a return to early October weather with a mainly sunny day on tap. Highs into the mid and upper 60s. Northwest winds 5 to 15 mph.
Tuesday night, clear and much cooler. Lows in the upper 30s and low 40s inland to mid 40s along the coast. Winds drop off to near calm.
Wednesday, another mainly sunny day. Cooler, highs only in the low 60s, perhaps not getting out of the upper 50s along the coast. Northeast winds around 10 mph.
Wednesday night, becoming partly cloudy. Cool, lows in the low and mid 40s.
Thursday and Friday: Watching an offshore storm. Partly to mostly cloudy. Highs in the 60s. Overnight lows in the 40s. Rain is possible Friday if the storm tracks close enough, especially near the coast.
