Massachusetts can kiss its largely snowless winter goodbye this weekend, with most of the state expected to see at least 4 inches of the white stuff from a storm Saturday night into Sunday.

The precipitation is expected to start as snow Saturday night, before transitioning to rain, freezing rain, and sleet in parts of the state Sunday morning. The National Weather Service has issued a flood watch for southeastern Massachusetts, as 2 to 3 inches of rain are anticipated. Starting Sunday afternoon, temperatures will drop as Arctic air moves in, setting up conditions for a “flash freeze,” service meteorologists said.

Change over to a soaking rain Sunday across SE New England. Rainfall of 1-2", locally higher. FLOOD WATCH posted. Exiting late, surfaces remaining wet, looking at a FLASH FREEZE as Arctic air pushes in late Sunday into Monday.

[Flash Freeze Sunday Night into Monday Morning ] Temps plummeting beginning 1 pm Sunday. It'll be 20° colder by 1 am Monday & well below freezing w/ temps edging towards the single digits. Greatest concern along the Boston – Providence corridor and S&E for the Monday AM commute. pic.twitter.com/KH39TxGo1L — NWS Boston (@NWSBoston) January 19, 2019

All of Massachusetts, except for Cape Cod and the Islands, will be under a winter storm warning or watch for the duration of the storm.

A few minor tweaks but we're staying close to our snowfall projects from last night. DO NOT LET DOWN YOUR GUARD. We've become increasingly worried about ice and freezing rain. #wcvb pic.twitter.com/HDw0U6ocWN — Mike Wankum (@MetMikeWCVB) January 19, 2019
