.SHORT TERM /THROUGH TONIGHT/... Issued at 108 AM CDT Tue Sep 9 2025
Mid-level shortwave is currently over central MO, but very dry air over the area is limiting any precip to sprinkles at most.
Look for warmer conditions today with highs in the 80s. Another dry day over the central and eastern CWA with minRH values of 20-30%. Over the western CWA, minRH values will be 35-45% due to greater moisture levels that will also yield potential for some isolated showers or sprinkles.

.LONG TERM /WEDNESDAY THROUGH MONDAY/... Issued at 108 AM CDT Tue Sep 9 2025
The pattern currently features a mid-level ridge over the intermountain west and NW flow over the CWA. This pattern gradually shifts east, as is well agreed on by models. This results in mostly dry conditions and warming temperatures. Normal high temperatures are in the low to mid 80s, but the forecast is for highs in the low to mid 90s starting Wednesday, but especially Thursday through the weekend. Not forecasting any record highs right now, but will be worth watching at SGF, VIH, and UNO where the forecast is within 5 degrees of record highs.
Looking at next week, models continue to diverge on the pattern. About 30% of ensemble members are clustered in showing a mid- level low over the Great Lakes with a trough extending through our area. This would result in cooler temperatures and chances for rain. As such, the NBM has introduced 15-25% chances for rain Sunday night and Monday. Still, 70% of ensemble members show the ridge continuing to build over the area, which would keep our hot and dry pattern.
Looking at rainfall patterns through the rest of the month, the ensembles have been trending slightly wetter. While previous runs showed negative precip anomalies through much or all of September, latest runs show neutral anomalies (near normal rainfall) for the last 10 days or so of the month. Drought will continue to expand and worsen until more substantive rainfall occurs.

.AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1204 PM CDT Tue Sep 9 2025
For the 18z TAFS, remnants of a thunderstorm complex were pushing into west central MO, southwest MO and extreme southeast KS early this afternoon. Coverage is likely to diminish the further east it moves into the area given lack of instability and drier air. Have gone with VCSH at SGF and prob30 at JLN for coverage purposes with the showers, but ceilings should remain high enough for overall VFR conditions. We have convection ending by 00z. A light southerly wind generally less than 10 kts is expected through the period.
