UPDATE

Issued at 130 AM EDT MON JUN 1 2026

No significant changes were made to the forecast with mainly just the inclusion of the latest obs and trends for the T/Td/Sky grids. Did also include the current radar and CAMs guidance for some small PoPs into dawn. These minor adjustments have been sent to the NDFD and web servers along with a freshening of the HWO, SAFS, and zones.

UPDATE Issued at 1200 AM EDT MON JUN 1 2026

Updates were made to hourly grids mainly to account for observation, satellite, radar, and high resolution model trends. This generally resulted in lower pops for much of the area outside of the VA border into the day on Monday.

UPDATE Issued at 805 PM EDT SUN MAY 31 2026

Convection near the TN border has waned to a few passing sprinkles fall from what is left. Several hours of dry weather should follow though some convection may tend to redevelop overnight. Hourly temperatures and pops were freshened up based on radar, satellite, and observation trends.

LONG TERM

(Tuesday through Sunday) Issued at 342 PM EDT SUN MAY 31 2026

Tuesday, as patchy fog mixes out, high pressure over the Upper Midwest strengthens as the trough axis from the upper low in the Northeast continues to drop heights across the area. Slightly cooler conditions are expected ranging from the mid to upper 70s. Conditions will generally be dry with mostly sunny skies across the area except the Big Sandy, where the retrograding low could produce isolated showers and thunderstorms in the far east during the afternoon. As high pressure settles southeast in to the area out of the northwest, height rises will occur, leading to clear skies, calm winds and dry weather starting Tuesday night. Valleys could decouple heading into the evening leading to valley temperatures dropping into the upper 40s; while ridge tops remain elevated in the low to mid 50s. Patchy fog may develop, mostly in river valleys, but not necessarily confined to them.

High pressure continues to build into the region Wednesday through Friday. Through these days, dry weather can be expected, under light winds and mostly sunny skies. With height rises, temperatures will warm through Friday. Upper 70s on Wednesday will warm into the low to mid 80s by Friday. Lows in the evening will also warm, from the low to mid 50s Wednesday night to the upper 50s to low 60s both Thursday and Friday night.

An upper level low will traverse the Northern Plains and Southern Canada starting Tuesday afternoon. By late Thursday this upper low will be over the Great Lakes, breaking the ridge of high pressure down. Gulf moisture will creep north around an area of high pressure through the lower Mississippi Valley, into the Mid-Mississippi Valley by Saturday afternoon. This will lead to showers and thunderstorm chances across much of the area Saturday afternoon, and again on Sunday. Temperatures look to range from the low to mid 80s.

AVIATION

(For the 06Z TAFS through 06Z Monday night) ISSUED AT 145 AM EDT MON JUN 1 2026

An approaching wave aloft and a boundary lingering across the region could result in isolated to scattered showers early this morning generally for locations south of a KJKL to KLOZ line - with some sprinkles possible for the rest of the area. This convective potential continues after dawn with a thunderstorm possible into early afternoon in the far southwest. Otherwise, areas of fog will develop in the valleys generally south of the Mtn Parkway through the morning commute, though this is not expected to affect any of the TAF sites. Winds will generally remain less than 10 kts through the period, outside of any thunderstorms.

JKL WATCHES/WARNINGS/ADVISORIES

None.
