BEYOND

Tuesday's cold front doesn't pack a cold punch. We'd settle for a "less hot" punch, but the front actually lifts back north and temperatures remain toasty through the work week. Expect 90s to linger. The extended nature of the heat is concerning. With overnight minimum heat indices remaining in the mid-70s, rooms/buildings with no A/C will be very difficult to keep cool. Heat's impacts grow over the course of consecutive days.

Pattern recognition suggests that the area may be subjected to overnight MCS passages as the nocturnal LLJ feeds humidity and instability into the area. Should this materialize once or twice, severe weather is possible (especially winds), but temperature forecasts are subject to bust as remnant cloud cover or cold pools have been known to throw a cooling wrench into summer plans.

AVIATION /12Z TAFS THROUGH 12Z SUNDAY/

Issued at 552 AM CDT Sat Jun 27 2026

A mix of MVFR/IFR/LIFR conditions across the area with the TAF terminals staying mostly MVFR/IFR. Have removed mention of potential LIFR conditions due to it simply staying away from the terminal, with LIFR conditions staying closer to KPMV southward along the Missouri River and KJYR and KBVN westward. We'll see gradual improvement through the day, with cigs likely improving to VFR this afternoon (70% chance). Around 01-02Z, though, expect KOFK and KOMA to see low clouds return with high likelihood (80% chance) of cigs lowering back down to IFR at KOFK by 04Z, and a good chance (60%) at KOMA as well. KLNK will likely be spared from the return of low clouds tonight.
