Sunday remains steamy ahead of a cool down next week
A strong cold front could bring fall air late next week
A few isolated showers and storms are possible into the evening as a cold front nears the region then stalls out overnight. A few of the showers may end up being quite heavy with localized downpours, however, the severe thunderstorm risk appears low. Lows tonight dip to the upper 60s with areas of valley fog.
High pressure relocates Sunday which pushes the front farther south over the Carolinas. This should limit the shower coverage for many areas. Depending on how strong the developing wedge is, many areas will see a subtle drop from where high temperatures were earlier in the weekend. Highs reach the upper 70s across the mountains, and low/mid 80s east of the Blue Ridge Parkway.
MONDAY & TUESDAY
The first part of the week will be very similar to the weekend with spotty showers and lingering clouds along with mostly cloudy skies By the middle of the week. A northeast wind will help develop a “wedge” of cooler air Monday and Tuesday with highs only in the mid 70s.
By Wednesday, a strong cold front will move into the region bringing a better chance of rain followed by much cooler, Canadian air. It looks like the front may offer our best chance of widespread rain which may be heavy at times along/west of the Blue Ridge Parkway. Models differ on the speed of the front, however, it appears much of Wednesday should be wet until much cooler, drier air moves in Thursday.
Rainfall models are suggesting areas along/west of the I-81 corridor have the best chance of topping 1″ of rain. Meanwhile, rain will weaken as it moves east with lighter amounts toward Lynchburg and Danville.
Behind the cold front, temperatures at night will slip to the upper 40s in the mountain valleys and 50s elsewhere. Afternoon highs will likely never make it out of the mid 70s.
We continue to watch an active tropical map of potential storm development. The latest outlook from the National Hurricane Center is below. The red areas are where development is likely in the next 2-5 days. The next name on the list would be Peter. There are only 6 names left on the regular list of 2021 names.
