Increasing southwesterly flow has allowed a return to temperatures in the 70s with some increase in near surface (950 mb and lower per 12Z KILX sounding). Further increase in moisture will await the arrival of a cold front and a narrow swath of increased isentropic lift and lower CPDs to bring some potential for isolated to scattered showers (maybe a storm) Thursday. Greatest lift seems to exist during the afternoon, which would coincide with peak heating (although clouds may hamper that to some extent). Toned down likely pops in NW to higher chance for now.

The passage of the front will bring a push of CAA, essentially cutting off 10 degrees or so from the high temps we have enjoyed over the past several days. This is still above normal for the end of Oct. Sfc high pressure will build across the Great Lakes, keeping the warm and moist conditions just to our south through the upcoming weekend. Depending on the final resting place of the stationary front and fluctuations in its location, some chance for showers does remain in this period. By no means is there expected to be a washout and Halloween activities appear to be mostly dry.

Models are in agreement on an upper low moving to the Pacific NW shores by 18Z Sat. From here differences increase as a series on northern and southern stream waves either eject from this upper low or move into the SW US. GFS remains the most aggressive with a deeper upper low over OK by 6Z Wed, vs the EC/GEM that have a similar location but much weaker. Suffice to say, plenty of moisture will push north with this system but the timing of specific impacts to our area remain in doubt at this point.

Aviation

Issued at 1228 AM EDT Thu Oct 29 2026

A cold front is arriving from the west, currently slicing NE to SW across Iowa. Clouds will seep in during these early-morning hours which may have negative consequences to any redevelopment of showers (non-zero chance of thunder) this afternoon. High resolution ensemble guidance is in good agreement on at least isoalted showers along the cold front as it moves through KSBN and KFWA, yet not enough confidence to move beyond a PROB30. The inherited PROB30 MVFR conditions cannot completely ruled out at KSBN, and there are isolated MVFR observations upstream.

Wind quickly weakens beyond the front with high pressure moving in working quickly to dissipate cloud cover.
