WINTER PLETHORA: Interesting weather upcoming for the next few days as temperatures continue to warm across the state. One disturbance will skim the state to the southeast with a little bit of snow flurry activity in the southeastern counties of the state. The big deal is the system on Friday into early on Saturday. We could see some wintry precipitation to start out during the morning hours, some of which could be in the form of some freezing drizzle or sleet. All but the southeastern counties could see rain, sleet or snow during the day with all rain in the southeast. This will changeover to all snow later Friday night into Saturday as the storm begins to lift out. This is where it gets a little tricky. The GFS is showing a deformation zone setting up in the colder air Friday night into Saturday morning across the eastern counties of the state. This would indicate that some of the precipitation could be substantial at that time. This would more than likely be in the form of snow or possibly a mix at that time. Some of the models have been indicating some accumulating snow with this portion of the storm as it departs. Current thinking is that there may be a swath of at least 2 inches of snow, but it’s still a bit early as to where that will be setting up. The WPC has the swath over the northern and central counties of the state, but this run of the GFS would indicate that it would be 40 or 50 miles farther to the southeast. We’ll have updates on this later today.

INTO NEXT WEEK: A few fairly dry clippers come through Sunday, Tuesday and next Thursday with slightly cooler air following. The best we can get from these systems would be a few flurries or light snow showers at best. Temperatures during this time look to remain near to slightly above seasonal levels even with the colder air following each system which will drop temps back down.

EXTENDED PERIOD: The beginning of the period will see temperatures begin to rise above seasonal levels from the 18th through the 20th. It looks to be fairly dry during the period with only a smattering of some rain and snow around the 22nd and 23rd with another system approaching from the west as the period ends.
