KEY MESSAGES

- Rain persists through Thursday with on and off showers moving through the region. Most locations will pick up around 0.5-1" of additional rain over the next 48 hours.

- Temperatures decrease to just a bit below normal by Thursday/Friday as rain and widespread cloudiness continues before returning to above normal early next week.

DISCUSSION

Occasional rain continues through Thursday night

Upper low west of MCI with southerly moist fetch east of this feature will continue to lead to periodic showers across the region and plentiful moisture advects northward and upper disturbances move northeast. Slight break will occur when the upper low churns overhead Wednesday morning before wrap around disturbances move southwest over the CWA as the upper low departs to the east. While available moisture will be abundant today and tonight (03.12z DVN RAOB had a daily record 1.5" of PWAT) forcing for ascent is in the form of periodic shortwaves without the presence of a stationary or quasi-staitonary boundary usually needed for training. Finally, moisture and rain rates look to take a step downward as the upper low departs and drier air begins to filter in from the northwest. 03.12z REFS max rainfall reflects this with values of only around 1" of rain after 18z today. Therefore, while many locations will receive around an additional 0.5-1" of rain over the next couple days, flooding concerns are minimal.

Temperatures fall and then rise

Progression of the upper low over the next few days will allow for cooler air to push south into the region. This, combined with occasional light rainfall and cloudiness, will lead to temperatures in the upper 40s for Thursday and Friday, just a bit below normal for early November. While there is a good deal of interquartile temperature spread (8-10 degrees F per 03.13z NBM) Saturday and Sunday, guidance largely points toward subtly rising heights going into Monday of next week with around a coin flip (40-60%) chance for highs to reach 60 degrees.

AVIATION /00Z TAFS THROUGH 00Z THURSDAY/

Issued at 538 PM CST Tue Nov 3 2026

Low MVFR to LIFR conditions are expected throughout much of the TAF period as a weather disturbance pushes through the region, bringing off and on showers across much of the area. Consequently, the NBH has high probabilities (50-90%) for IFR cigs at KRST and KLSE. Additionally, visibility reductions to IFR thresholds will likely accompany any heavier showers throughout the TAF period as well. Off and on showers will likely persist through the TAF period and even will continue into Thursday as the disturbance overhead slowly meanders eastward. Therefore, probabilities in the recent REFS maintain high chances (50-80%) for IFR cigs all the way through Thursday afternoon. Otherwise, winds will begin the TAF period from the south at around 5-10 kts before shifting towards westerly by late morning and into the afternoon on Wednesday and increasing slightly to 10-15 kts.
