The classic pattern of sharp cold waves separated by big warm ups will hang tough through March. Near-term, the upcoming weekend will bring a massive reversal to our late-February warm spell.
The jet stream will again carve out a deep, cold Eastern U.S. trough, helping spawn new storm development just to our south Saturday. That system will drive northward along the Virginia coast, tugging much colder air eastward, and assuring us of a cold and rainy start to the weekend. There could even be some snow in the higher elevations from the far western Piedmont and across the Blue Ridge.
Cold weather will then carry us into the first few days of March.
