Low pressure will move up from the south and intensify somewhat as a coastal low on Saturday. As mentioned in my post earlier this week, this would ordinarily be a snowstorm here, but the lack of cold air will make this a rainstorm.
Saturday will be rainy through most of the day, tapering late afternoon and ending early evening. High temperatures 46-48. It will be somewhat windy.
Things dry out for Sunday.
Sunday will be mostly sunny, windy and cooler. High temperatures 44-46. (Average highs now are 39.)
Forecast Update Saturday 11 PM
Sunday forecast looks to be cloudy in the morning with sun breaking out in the afternoon. Temperatures chill down for Monday (Highs in the 30s) with a brief warm up Tuesday (High near 50); Temperatures chill down again Wednesday night into the weekend.
The medium range models are showing some winter-like cold air moving in Wednesday night into Thursday and lasting into the weekend. This dip in the jet flow will primarily affect the eastern and northeastern sections of the US.
After another warmup, the overall weather pattern is expected to gradually change into a much colder pattern during the third and fourth week of January as a mass of colder air moves down from Canada into the central US.
