The cold front has pushed through Virginia into North Carolina, as shown by Friday evening’s map from the Weather Prediction Center at left, and high pressure in Canada (the little blue “H” marks the center of it near the Great Lakes) is pushing in drier and somewhat cooler air for the weekend. I say “somewhat cooler” because this will not quite be “taste of fall” stuff that we had a little more than a week ago, but Sunday and Monday mornings could produce lots of 50s in the region, maybe even a few 40s in outlying areas, and highs will be 70s to low 80s Saturday, Sunday and Monday. Rain chances appear to be very low this weekend in Southwest Virginia, with drier air and the sinking air underneath the dome of high pressure discouraging convection. Next week will offer some gradually warming and moistening air, with chances of afternoon showers and storms returning by midweek. Longer term, some forecast models are hinting at an expansion of high pressure in the central and western U.S. bringing something of a late -summer hot period to much of the East, perhaps around Labor Day. Any kind of tropical system in the Gulf or western Atlantic not accounted for yet or a couple of cold fronts from the northwest could dampen that quite a bit.
