KEY MESSAGES

- Another cold front will cross the area on Friday and usher a colder and drier airmass into the region for the weekend. - A widespread frost is likely this weekend, and a freeze is also possible. The coldest temperatures will be in the deeper valleys.

LONG TERM

(Friday night through Wednesday) Issued at 355 AM EST THU NOV 5 2026

The main story for the first part of the extended period will be the cold weather that settles in behind the Friday cold front. A trough over the Great Lakes region will barrel down towards the Upper Ohio Valley and Mid-Atlantic states through the early part of the weekend. As the 500 mb trough moves east of the area, cold air will begin to work in for Saturday and following lows in the 30s to around 40, daytime highs are not expected to get out of the 50s. Cloud cover will gradually diminish as the upper level system moves off to the east, which will lead to low temperatures trending colder for Sunday. Strong ridge valley splits are expected for both Saturday and Sunday night as nighttime lows are expected to be in the 30s for ridge tops and the 20s for the more sheltered valley locations. A widespread frost and/or freeze appears likely for both nights.

High pressure will build across the Commonwealth through the early part of next week, leading to dry weather and near normal temperatures. Model solutions indicate a more active pattern developing around midweek. LREF and ECMWF indicate the potential for troughing developing across the eastern CONUS, while the GFS is more aggressive and brings a strong upper-level low into the Central Appalachians vicinity on Thursday. Given the model spread, there is still uncertainty with the location and evolution of these features. These will continue to be monitored for potential precipitation chances as we head into late next week.

AVIATION

(For the 06Z TAFS through 06Z Thursday night) ISSUED AT 115 AM EST THU NOV 5 2026

A mixture of mainly IFR and MVFR was reported at issuance time, with locally lower reductions reported along or near a cold front moving through the eastern counties. Gradual improvements to MVFR should occur behind the cold front with stratus or stratocu remaining for a while, particularly over more eastern locations. Patchy fog is also possible given the wet grounds, and this combination of fog and low stratus should keep mainly MVFR to IFR conditions in place overnight. Conditions will gradually improve to VFR as drier air moves in and skies clear throughout the day on Thursday as high pressure briefly noses into eastern KY. Valley fog may develop before the end of the period and could result in reductions to MVFR or lower.
