KEY MESSAGES
- Active weather through the week will produce on average one half to one inch of rainfall in total, with the best rain chances, including heavier rain chances, occurring Tuesday and Friday.
- Weeklong temperatures will spend the majority of their time in the 60s at night and 70s during the day, though official high temperatures may reach toward or into the lower 80s briefly.
DISCUSSION
Issued at 224 AM CDT Mon May 25 2026
Cloud cover is spreading northward through the Quad State which should keep fog from becoming widespread. However, visibility drops are occurring and periods of very localized areas of denser fog are possible. Northern spots likely will reach their lows in the 50s before clouds move in, while areas to the southeast will hold in the lower 60s. A dry day is finally forecast today for most of the Quad State (a slight chance to chance in the southern Pennyrile being the exception) with light winds continuing as high pressure moves across the Midwest.
A boundary located to our southeast will slowly lift north and become more zonally oriented Tuesday through Wednesday. This will result in a band of showers lifting northward Monday night into Tuesday as moisture streams in on the warm side of the boundary. A few thunderstorms are possible during the day Tuesday though severe weather is not expected as shear continues to be trivial. A negatively tilted ridge builds from Alberta to the southeastern US midweek, stalling eastward progress of a Southern Plains system and keeping rain in the Quad State Wednesday as well. The front pushes back south as high pressure builds in the Great Lakes and a Rex block pattern develops. PoPs remain for the end of the week into the weekend, at least for now, though the heavier rain potential is south of the Quad State. Overall, QPF is down to half an inch to an inch which is starting to reduce its effectiveness at helping alleviate the drought though should keep drought conditions from worsening. It would take training of storms or moderate to heavy rain to even produce a bit of localized nuisance flooding.
Temperatures through the week will primarily be in the 70s during the day and 60s overnight. Once the boundary passes to our north, Wed-Thurs highs will more likely rise to the 80s with lows in the mid-60s. A return to 70s for highs is projected for the end of week and weekend as the boundary slips back south.

Conditions will deteriorate as showers push north through the region overnight into Tuesday morning. MVFR conditions are a good bet at all sites, and IFR ceilings are expected at KPAH.
Confidence in IFR or lower conditions elsewhere is low at this time.
