Final Call For 1-25-13


A light snow event is on the way for Friday. A clipper like system will be approaching the region and will be responsible for the light snow on Friday. This clipper will redevelop off the coast of Hatteras but instead of moving up the coast it will move more to the East North East and the coastal redevelopment will happen to late and to far in the Atlantic to have any additional effect on the snowfall.
Very cold air has been in place for the last couple days so whatever snow does fall will not have any problem sticking. With models generally printing out .1 to .25 across the region with the exception of parts of West VA and VA ..the general call is for 1-3 inches with lighter amounts to the north and heavier amounts in the area where guidance is printing out .25-.50 inch liquid equivalent.
The flow is just to fast and progressive to allow the two jet streams to phase together and so we are left with a lighter snowfall...

Where do we go from here? Guidance is suggesting temperatures will slowly moderate so that by the beginning of the week we will be looking at temperatures above normal with ridging occurring over the east as a trough will advance from the west central conus. This will result in a warm up with temperatures in the 40s to near 50 in the east and a low pressure forming in the southwest that will head up towards the Great Lakes into the Northeast dragging a cold front across the region and introducing our next chance for precipitation in the form of Rain . After this cold front goes by we will once again return to colder weather.
