Back-to-back storm systems will lead to heavy rain in Southeastern New England Friday into Saturday. Localized street and stream flooding is likely. Some of the heaviest rain will likely be in Southern RI and SE MA, where 3-4″ of rain is possible. The rain, combined with temps in the 50s and rapid snow melt, will lead to localized street flooding, and some streams may rise, too. The timing of the heaviest rain is Friday night into Saturday morning.
Expect clouds and milder temperatures on Thursday. It will be good to get gradual melting before the rain arrives. Highs will be in the 40s to near 50 throughout Southeastern New England. It will be coolest near the bay and ocean. Thursday night looks damp and mild, with drizzle, mist, and showers possible. It will get rainy on Friday, especially late in the day and at night. 2-4″ of rain is likely in RI and SE MA by midday Saturday. The temperature will spike into the 50s, and possibly reach 60° in spots! Expect strong southerly wind gusts on Friday, that may reach 35-45 mph.
We’ll be watching for cold air to move in quickly as the storm departs Saturday afternoon. The temperature will fall through the 40s and 30s into the 20s by Saturday night. It may not be a flash-freeze, but any remaining slush or puddles will freeze Saturday night.
The weather looks quiet and cold Sunday through at least early Tuesday. A storm system may develop near the New England coast bringing snow, mix and rain to Southeastern New England. At this point, the track looks like it may be close enough for a mix of snow and rain in most of RI and SE MA. The best chance of a plowable snow is inland. It’s a long way down the road, and I’ll keep you updated.
