SHORT TERM /THROUGH TUESDAY/

Issued at 145 AM CDT Mon Oct 19 2026

Current Conditions and Synoptic Overview: Water vapor and upper air analysis highlights several key features across the country with upper level energy across the southwest, an upper low off the east coast and a ridge over the south central US. Surface winds were light out of the south across the area. The 00z KSGF sounding continued to measure a dry airmass in place with a PW value of 0.38in. Mostly clear skies and light winds have allowed for temps to fall into the 40s across a large part of the area. Locations that are protected by the wind or in river valley areas are seeing temps in the 30s.

Increasing High Temps, Cool Nights: The area will see an increase in mid and high clouds today and Tuesday as shortwave energy slides in from the southwest. The airmass is dry and no precip is expected. High temps in the upper 60s to lower 70s are likely both days however cloud cover could keep temps a degree or two below their maximum potential. Given the dry airmass in place, temps will fall off quickly in the evenings with very similar low temps tonight. Coolest temps will again be to the east of Springfield in the valleys and wind protected regions.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/

Issued at 145 AM CDT Mon Oct 19 2026

Above Average Temps and Dry Conditions Mid/Late Week: Ensembles are in decent agreement that the mid level ridge will expand north as upper energy moves into southern California. 850mb temps will gradually warm into the 12-16C range and this will support gradually increasing temps. High temps will reach the upper 70s to around 80 from Wednesday through the end of the week. These temps are roughly 10 degrees above average for mid October. This upper level pattern does not favor rain chances with chances staying below 10 percent through the end of the week and next weekend.

AVIATION /12Z TAFS THROUGH 12Z TUESDAY/

Issued at 519 AM CDT Mon Oct 19 2026

Confidence is high that VFR conditions will prevail through the TAF period. There will be increasing mid and high clouds through the day, especially at JLN. Winds will remain light out of the southeast with speeds generally less than 10kts.
