.SHORT TERM /THROUGH TUESDAY/... Issued at 102 AM CDT Mon Sep 8 2025
Mesoanalysis reveals the 850 mb high is sitting directly overhead today which will largely keep our weather quiet. A shortwave impulse will translate through the Plains this afternoon and initiate convection across portions of Nebraska and Kansas. This activity may approach the western fringes of our CWA this evening into Tuesday morning, but a very dry airmass will prevent it from making it very far into the Ozarks. The relative best chances to see any rain at all will generally be along and west of the I-49 corridor where dew points are modestly higher near 50 degrees. The latest HREF probabilities of locations measuring at least 0.10" of rainfall that way are in the 20-40% range. Probabilities of receiving a quarter inch are 30% or less.

.LONG TERM /WEDNESDAY THROUGH SUNDAY/... Issued at 102 AM CDT Mon Sep 8 2025
Upper-level ridging is progged to develop across the central CONUS during the middle to end of the week which will largely keep the Missouri Ozarks in a dry and warm pattern. Forecasted 850 mb temperatures in the 20 to 22 C range are above the 90th percentile of climatology and typically correlate to surface temperatures near 90 F. Indeed, NBM data show small forecast temperature spreads through the end of the week with highs in the upper 80s to mid 90s. For reference, climatological average high temperatures for this time of year are in the 80 to 84 degree range. These warm temperatures combined with the lack of meaningful rainfall may exacerbate drought expansion across the region. Furthermore, extended ECMWF and GEFS runs both suggest below-average precipitation anomalies continuing well into the month of September.
Ensemble solutions begin to diverge more significantly by the weekend. A majority of grand ensemble members (70%) keep the aforementioned ridge overhead, keeping rain chances to a minimum, while the other 30% favor a more progressive shortwave moving into the region, which would at least open the door for some rain chances. For now, NBM PoPs in our area remain low through the weekend.

VFR conditions are likely through the TAF period. Some high clouds will persist through much of the day, and south-southeast winds will remain generally less than 12 kt.
