You'll need the umbrella this afternoon. The drizzle will lead to steadier and heavier rain this afternoon and evening. It looks as though we'll pick up about .5 inch of rain by the time the rain pushes out, overnight tonight. The bulk of the rain will fall from mid afternoon through mid evening.
Initially behind this system it remains mild but colder more seasonable air will move in just in time for the weekend, as a push of Canada air moves in. After a mild day tomorrow temperatures will be more December-like with highs in the upper 30s and lower 40s on Saturday and Sunday. The wind on Saturday will make it feel a bit colder and there could even be a few snow showers Saturday morning, as the colder air moves in. There could be a few coatings around the area! It will be the coldest weather this season so far, but certainly nothing unusual for this time of year.
The cold weather doesn't stick around long. After Sunday, the mild air returns. High pressure will set up off shore causing the jet stream to lift into Canada as another ridge builds across the east. This will cause temperatures to run above normal for all of next week including Christmas Eve and Day.
