KEY MESSAGES
Updated at 732 PM EDT Wed May 13 2026
- Will see a few showers and possibly thunderstorms this afternoon and evening. Still low confidence on if any storms can become strong to severe mainly northeast TN into southwest VA, but if so damaging winds will be the primary threat.
- Big warm up for the weekend into early next week.
- Next significant chance for showers and storms expected to arrive by next Wednesday.
DISCUSSION
Issued at 220 PM EDT Wed May 13 2026
The cold front on our doorstep will sweep through this afternoon/early evening along with a few showers and possibly thunderstorms. Convective energy continues to look quite limited but given the significant shear and a brief uptick in DCAPE, if any stronger storms are able to develop there continues to be a marginal threat of damaging winds especially across portions of SW VA and NE TN.
Cooler and drier air will push in behind the front for Thursday and Thursday night. Lows Thursday night will be in the lower to mid 40s for most folks, but a few may see upper 30s.
Upper level ridging will build in Friday, setting the stage for a strong warm up. Temperatures by the weekend into early next week will be well above normal, and high temperatures will flirt with 90 across portions of the valley during the Sunday through Tuesday time frame. It looks mostly dry for Friday through early next week. Weak short wave energy does slide by to our north and this may bring a few showers or storms Saturday mainly northern areas, although models continue to trend drier for our area.
The next front is forecast to be approaching by the end of the period although timing is quite uncertain that far out. With the expected approach of the front, chances for showers and storms will increase a bit for Tuesday and more significantly for Wednesday.
AVIATION
