What a great start to the work week with sunny skies and seasonally average temperatures in the mid to upper 40s. Changes lurk on the horizon but I think you're going to like them. Highs tomorrow and Wednesday should reach the 60 degree mark once again. It appears like it will be the 6th time we've reached that mark in January, though it will be close as some of the models only top out at 59... At least we don't have to worry about -60 degrees like Alaska!
Rain does appear to be likely by Wednesday afternoon or evening as a frontal system approaches the region, but as our 7 day shows, the better chance will be through the day on Thursday as the trailing cold front passes through. Rainfall totals appear like they will be light, with the HPC painting about a quarter to a half of an inch for the D.C. area. It appears that January will end up about 4.5 degrees warmer than normal for the month and about a half of an inch below normal as far as precipitation is concerned.
Biggest question marks in the forecast this week?
The main question appears to be for the weekend at this point, as the latest model set differs significantly on the outcome. Neither of them spell anything in the way of winter precipitation but they do have differing opinions on if the weekend will see rain.
