NWS ALY LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
There is the potential for a major winter storm to impact our forecast area over the weekend. The period kicks off with low pressure over the Arklatex region quickly moving into the mid- Atlantic region and northeast. This first system looks like it could give us a quick 2 or 3 inches of snow Thursday night.
Behind the departing-for-the-Atlantic-Provinces system, high pressure centered over southern Canada will ridge in down the mid-Atlantic coast to provide a brief period of dry conditions Friday night before the more substantial system moves in.
This one is expected to develop as a wave off the Colorado Rockies, gaining strength on its way to Arkansas, then quickly tracking toward the Mid-Atlantic region. Today...the ECMWF and GFS models are both in very good agreement that this will be a high-impact event. Right now the focus is on Saturday night and Sunday.
The real cold arrives Sunday night, with lows ranging from around 10 degrees below zero to around 10 above.
