Forecast discussion: We are beginning to see any rain changeover to freezing rain or sleet west of Boston. There will be several more hours of precipitation, changing over to wet snow, before it begins to taper off in the pre-dawn hours Friday morning. There is the chance of a coating to an inch of wet snow in the southern parts of Metro Boston, while northwest of the city could see 1-2 inches. This will make for a messy and possibly slippery morning commute. A Freeze Warning is in effect for parts of eastern Massachusetts from 4 AM until 8 AM Friday morning. High pressure will bring sunny skies to us this afternoon, and bring near freezing temperatures tomorrow night. The next storm I am watching is from the precipitation that gave Denver a few inches of snow a few days ago. A low pressure system will form off the coast of North Carolina. Many of the computer models are coming in agreement of this low forming. The bad news is the models disagree on the speed and movement of the low. The American and European model keep the low much closer to the coast, making for a windy, rainy start Saturday afternoon, before changing over to wet snow late Saturday night. There is the chance that Providence would see 1-3 inches, with 2-5 inches north and west of the capital city. A new high pressure system will bring mostly sunny skies, and we will return to seasonable temperatures. On Thursday, there is the slight chance of seeing some showers from another coastal low, but my confidence in Thursday’s forecast is quite low.
