- Temperatures will average within a few degrees of normal over the next week.

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 18Z TAFS through 18Z Monday afternoon) ISSUED AT 137 PM EDT SUN MAY 31 2026

VFR conditions will prevail through 05Z this evening. A disturbance is expected to lead to increasing moisture from the south and west where convection/low clouds could move into, or develop, in areas near KSME and KLOZ. A late night PROB30 has been added to the TAFs of those two terminals. Winds through the period will be light and variable. Fog may develop overnight but should remain confined to the valleys due to elevated winds aloft, though there is an outside chance fog could cause a reduction at KSME and KLOZ between 06-12Z. Ceilings should gradually improve after 12Z.
