Rain will finish the weekend

After a dry start to the last weekend of November, it won’t finish that way as Low pressure moves up through the St. Lawrence Valley in Canada Sunday evening. Clouds will start the day, but light rain arrives for the afternoon and will likely become briefly heavy during the early evening hours before ending by Midnight. Highs will reach into the upper 40s Sunday. Monday will be a bright sunny, but colder day with highs near 40°! In fact, most of the week ahead will be cold and the weather looks to remain rather active. This sets us up for a wintry mix across southern New England Tuesday and Tuesday night.

Right now this looks to be a relatively quick moving event about 12-18 hours as there will not be any blocking set ups in the North Atlantic to slow it down. What is still be worked out is how close this will track to southern New England and a shift of really 50 miles will result in huge precipitation difference across RI. By Sunday evening I’ll start to get a good look at higher resolution model guidance in order to describe some greater details and timing of this event. A of right now (Saturday evening) it looks like the southern half of RI will stay all rain. Some wet snow will likely mix with the rain along the I-95 corridor. Slippery conditions may develop in the NW corner of the state and the further you go up into Worcester county of MA the more likely it’ll be for plowable snowfall amounts to occur.

The sun will return Wednesday afternoon and last through Friday, but it will remain cold.
