Forecast discussion: Two low pressure systems over the eastern Great Lakes and southern Vermont did not bring any precipitation today, but it did help bring tropical air into Southern New England. In fact, T.F. Green Airport in Warwick reported we broke the all-time high temperature for December 22 by hitting 64 degrees, breaking the old record of 61 back in 1990.
We will see one more night of milder temperatures, before we see heavier rainfall. A third low pressure system over Tennessee will move towards the northeast during the overnight. We will see showers and light rain arrive during the overnight, and continue throughout Monday. Also, the cold front will pass through, and temperatures will drop throughout the daytime hours. Any showers will change over to snow showers around midnight, but end before the morning commute on Christmas Eve.
It will be colder on Christmas Day, as daytime highs stay well below freezing. Some milder air moves in for Thursday, but a quick clipper type system may give us some passing snow showers in the afternoon. A high pressure system will move in for our weekend, giving us mostly sunny skies for Friday and Saturday.
Sunday looks to be an interesting day to the models. A cold front will slowly make its way through the Great Lakes during the day, and we could see some snow showers by late Sunday night. For now, I am expecting increasing clouds starting Sunday afternoon, as the moisture works its way closer to Rhode Island.
