UPDATE

Issued at 633 AM EDT WED JUN 11 2025

LONG TERM

(Thursday night through Tuesday) Issued at 312 AM EDT WED JUN 11 2025

While a zonal jet stream will remain active well north of the area into early next week, a weak upper low over the Texas Friday will gradually move northeast toward the Lower Ohio River Valley through the weekend, before slowly moving east toward the Mid- Atlantic region toward the middle to later part of next week.

Warm moist advection into the region will support PWs increasing to near or slightly above 2 inches by the weekend, with dew points rising into the upper 60s to lower 70s. The plentiful moisture and moderate to strong diurnal surface heating will support daily chance to likely PoPs for the region beginning Friday and extending through at least Tuesday of next week. While effective bulk shear values would suggest little chance of severe weather, the lack of strong steering flow will mean a higher potential for slow-moving storms capable of producing downpours capable of causing some localized high-water concerns in the typically flood-prone and poor drainage areas.

Temperatures will vary little from day-to-day through the period with muggy conditions in place and little to no change in the overall pattern, with generally mild muggy lows in the 60s with valley fog in the mornings, and highs generally in the 80s each day.

AVIATION

(For the 12Z TAFS through 12Z Thursday morning) ISSUED AT 730 AM EDT WED JUN 11 2025

Sub-VFR conditions will be possible at times until fog lifts and/or burns off, which should occur by 14z. Otherwise, VFR conditions are expected through the period under mostly clear skies, though valley fog will again be possible at the end of the period at KLOZ and KSME. Winds will remain light through the period.
