At the time of this blog post a cold front is crossing the Blue Ridge mountains on its way eastward. The boundary is being propelled by a large southward dip - a trough - in the jet stream. Winds over Mecklenburg county will swap around out of the west by midmorning today (Monday) as that front pushes through. No rain is expected since the air both ahead of and behind the boundary is fairly dry.
Temperatures which bottomed out in the upper 50s around the county early this morning will rise to the 70 degree mark this afternoon under sunny skies. Those westerly winds will pick up in intensity, gusting over 20 mph at times. They'll calm down after dark, combining with clear skies and dry air to allow the day's heat to quickly radiate away. As a result temperatures will sag into the low to mid-40s by dawn Tuesday.
Tomorrow will feature sunshine for the first part of the day, with a westerly breeze that won't be quite as gusty as today. Temperatures will top out in the low 60s Tuesday afternoon under cloudier skies as that upper level trough approaches the region. Tomorrow night will remain cloudy while temperatures drop into the upper 30s(!) by sunrise Wednesday. And a few numerical weather models hint at the chance of light showers late Tuesday afternoon into the overnight hours.
The cooler spell will hold on for the rest of the work week. This graphic looks a lot different than the heat across the nation during recent weeks, with frost and freeze warnings expected as far east as the Appalachian mountains.
However, longer range outlooks show a warmup by next week, with above average October temperatures returning. It's autumn, the time when winter's cold and summer's heat vie for supremacy!
