.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.
