Another week has arrived but just like last week, we’re starting off with a messy storm. Unlike last week, this one should go over to rain in most spots, and the rain could be quite heavy as we get into Monday night and early Tuesday.
The storm system that brought all the severe weather to the Deep South and the Southeast over the past few days will move into the Appalachians today while a secondary low pressure area starts to take shape off the Mid-Atlantic coastline. This secondary low will quickly become the dominant storm as it intensifies while moving north-northeastward, passing south and east of Cape Cod on Tuesday. This will be mainly a rain storm from Boston southward, but a wintry mix of snow, sleet, freezing rain, and rain is likely north and west of Boston for a while on Monday. Eventually, warmer air moves in by early Tuesday morning, changing everything over to plain rain. The rain may be heavy early Tuesday, and as a result, Flood Watches have been posted for parts of Southern New England. Some areas could see 2-3 inches of rain, possibly even more than that. In addition, we’re looking at strong winds with this storm, especially close to the coastline. High Wind Warnings are up, with some gusts of 50-60 mph or more possible, especially across Cape Cod.

Once this system moves by, things dry out a bit on Wednesday, but another cold front brings in more showers on Thursday. After that, high pressure builds in for the end of the week and the weekend, with more seasonable (read: colder) conditions settling in.

Monday: Cloudy and breezy with some occasional rain or snow showers, drizzle, and maybe a little sleet, all becoming a steadier rain (light snow well north and west of Boston) by late in the day. High 31-38.
Monday night: Windy with any remaining wintry mix becoming rain across the region. Rain may be heavy at times, mainly across eastern Massachusetts, and especially south of Boston and across Cape Cod. Temperatures slowly rise overnight.
Tuesday: Rain tapers off to showers and winds gradually diminish across the region. High 34-41 north and west of Boston, 42-49 south and east, with some spots across Cape Cod possibly breaking into the 50s.
Tuesday night: Showers gradually ending from west to east. Low 30-37.
Wednesday: Morning clouds give way to partly to mostly sunny skies by afternoon. High 40-47.
Thursday:Mostly cloudy and becoming breezy with scattered showers, mainly early in the day. High 44-51.
Friday: A mix of sun and clouds, breezy, chance for a few snow showers. High 34-41.
Saturday: Partly sunny. High 32-39.
Sunday: Partly to mostly sunny. High 31-38.
