NWS 4am discussion. The high to our north will migrate eastward over the Northeast Sunday night as zonal flow aloft deteriorates and a shortwave trough digs into the Ohio Valley. Come Monday morning, surface low pressure will develop near the North Carolina coast, tracking north northeast throughout the day. The resultant weather locally will be precipitation breaking out overnight Sunday and lingering through much of the day on Monday. With the high to our northeast helping to supply chilly conditions, wintry precip concerns emerge for our Blue Ridge westward zones late Sunday night and into the day on Monday. Ensemble guidance continues to indicate the potential for accumulating snowfall across portions of northern and western Maryland, eastern West Virginia, and western Virginia. Will iron out the finer details in the coming days, but model consistency does bring confidence in at least a slight winter storm threat for accumulating snowfall in the areas noted above.
