Forecast discussion: A low pressure system just passing off eastern Long Island brought a little snowfall on Tuesday. We began to see some flurries just after the morning commute. We then saw light snow, with occasional bursts of moderate snow. However, around Rhode Island, about a coating to an inch fell. As the low passes into the Gulf of Maine, northern Rhode Island will see light snow reduce to flurries. Another inch or two will be added to the snowfall. The Winter Weather Advisory in effect for Rhode Island will end at 10 p.m.
High pressure moving into northern Arkansas will push low towards the northeast. We will see mostly sunny skies for Sunday, with temperatures actually going above freezing for the first time in several days. As we move into Wednesday night, winds will begin to turn to the southwest. This will allow for warmer air to move into Southern New England. We will actually push 40 degrees on Thursday.
By Thursday evening, a low pressure system now over eastern British Colombia will move into the Central U.S. It will begin to pick up some upper level dynamics, and move over New England Friday night. We will see scattered showers by early Friday evening, with the precipitation ending during the overnight hours. We will see a brief period of dry weather until a second low begins to race toward the Northeast. More showers will arrive by late Saturday afternoon. Showers and periods of rain will occur on Sunday, and temperatures will actually reach the lower 50’s. So, any snow and ice on the sidewalks and ground should melt and be washed away.
All the rainfall will end by Monday morning, as high pressure from central Canada moves quickly towards New England. However, colder air will be behind the cold front that will pass through the area. We should see temperatures in the middle 40’s before falling through the day. By Christmas Eve, it will feel like Christmas, but it will not look like Christmas. Right now, we would go into Christmas Day without a White Christmas.
