DISCUSSION

Issued at 240 AM CDT Tue May 26 2026

A west to east oriented boundary is moving northward through the Quad State as weak upper level low pressure lifts northward with light showers approaching from the south. Increasing cloud coverage will limit fog potential and increased moisture will keep lows in the mid-60s for the morning. Heading into the morning, shower coverage will become widespread. A few thunderstorms are possible, mainly in the afternoon. Sounding profiles continue to show high precipitable water values, while a total lack of shear negates the meager instability, keeping lightning and locally heavy rain the only hazards.

The upper low slowly drifts eastward tonight through Wednesday keeping showers and a Wednesday afternoon thunderstorm or two in the forecast. A Great Lakes system Wednesday night pushes a trailing cold front into the Quad State and pushes the lingering boundary back south. QPF is highly concentrated in the today/tonight timeframe with a tenth to a half inch in the north and around an inch in the Southern Pennyrile, with lighter amounts Wednesday. A marginal ERO covers the Quad State today but it will take training and stalled out thunderstorms/heavy rain to get any localized nuisance flooding.

A negatively tilted ridge stretching from Manitoba to the Southeastern U.S. midweek stalls out a Central Plains disturbance. High pressure drops south into the Midwest, introducing northeasterly winds and dry conditions in the Evansville Tri-State Thursday. Further intrusion from the Midwestern high is becoming more prominent in model ensembles, cutting off late week precipitation to mostly just Southeast Missouri which may be caught up in a NW-SE oriented area of showers on the west flank of the ridge. Half an inch of rain is forecast in the Ozark Foothills with dry conditions in the northeastern half of the Quad State. Over the weekend, the Midwestern high becomes entrenched over the area and should keep conditions dry into early next week.

High temperatures amidst plenty of showers today will likely remain in the upper 70s to near 80. As the boundary pushes north, lower 80s for highs becomes more common midweek, dropping back to the 70s as northeasterly winds arrive for end of week/weekend. Lows in the mid-60s through midweek with elevated moisture lower to near 60 for end of week/weekend as drier air moves in.

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/

Issued at 1127 PM CDT Mon May 25 2026

An initial band of MVFR ceilings with isolated to scattered showers is working into the region from the southwest and is forecast to begin impacting TAF sites by 7-8z or so with earlier arrival at SEMO/WKY terminals southwest of the TAF sites. Another surge in lower level moisture and lift works in from the southeast a little later and should result in more widespread rain and rain showers. Degraded flight conditions with low MVFR to IFR conditions with restrictions to both ceiling and visibility are anticipated for several hours from the late overnight through the mid morning hours Tuesday. A gradual decrease in precip should follow by the afternoon although scattered showers look to remain in the picture much of the day with prevailing MVFR ceilings reasonably likely through 06z Wednesday.
