Issued at 400 PM CST Mon Nov 24 2025 H5 trough axis is moving across eastern Kansas during the late afternoon hours. The primary vort maxima passed over the MO-KS state line around 19z this afternoon and will slowly move eastward. The next round of heavier shower activity has developed, and will continue to follow the forcing east-northeast across central Missouri before exiting the forecast area. Lower cloud bases have arrived with this. Visibilities have dropped below 2 miles with the afternoon rain shower activity. A few of the stronger showers have produced in-cloud lightning as detected by GOES GLM. This lightning and thunder activity has remained very isolated. Through the evening, a stronger H5 vort max and trough digs into the Northern Plains. While most of the forcing with this avoids the area, it will play a role in pushing the current short-wave east of the area, as well as providing mid-level height rises for a few hours during the overnight and developing a surface anticyclone. This passes through sometime after 05z-06z this evening, and will bring an end to most of the shower activity. This will also start to push a cold front toward the area. The dry air associated with the cold front though will take a bit longer to advect from the Plains into the lower Missouri River Valley. With weakening winds and plenty of moisture from the precipitation, fog developing overnight through Tuesday morning is possible. The main factor that could inhibit fog would be if cloud cover lingers, which limits radiational cooling. But rapid cooling may not be needed with the rich moisture supply, relative to cooler seasons, that has moved in during the past 36 hours. Surface anticyclone then centers over Central Missouri by early Tuesday afternoon but will continue to push eastward. Any mid-level height rises will came to an end as the trough over the Northern Plains moves eastward, which will deamplify any semblance of a ridge into a brisk zonal flow. Once the anticyclone has moved further east, the primary temperature cold front starts to move through late Tuesday afternoon and evening. If there is enough moisture, there is the possibility for light rain activity. The NBM has held onto some low end probabilities for light rain Tuesday late afternoon, though will point out a few deterministic solutions and several current ensembles remain dry. Will leave slight chances mainly east of Hwy. 65 for late Tuesday. Wednesday and Thursday, broad surface anticyclone develops across the Central CONUS that will push a polar airmass across the area. This will result in afternoon high temperatures in the lower to mid 40s, with overnight lows in the upper 20s. There will be a strong closed-low system traversing the Great Lakes Region. Central Missouri may see a stronger pressure gradient Wednesday and Thursday, resulting in gusty winds, and perhaps wind chills reaching the lower 30s. The forcing from that closed-low system is progged to miss our area, thus keeping the forecast dry. By the end of the week, a strong PV anomaly is expected to develop a deep trough across the western CONUS with the potential for a stronger surface cyclone to develop across the Central Plains, with forcing expanding into the Mississippi River Valley. This will be the next opportunity for precipitation across the area. Probabilities for QPF exceeding 0.25 inches has been increasing, and showing some decent pockets for liquid QPF 0.50-0.75 inches. This will make for wet travel Friday into Saturday next weekend. There is potential for subfreezing temperatures to arrive, especially for north-central and northeast Missouri. At some point between Friday Night through Saturday, a rain-snow mix is possible. Activity Friday Night, if there is anything frozen mixed, is not expected to accumulate. Saturday morning and afternoon though, there are better probabilities for temperatures dropping below 32F, and could result in some snow accumulation from north-central Missouri to northeast and eastern Missouri. It is still difficult to pinpoint amounts at this time. We are unsure how much moisture return we will actually get, and, if the forcing for precipitation will occur during the subfreezing temperatures. There are a lot of factors that could prevent snow accumulation. There will be potential some FGEN and other ageostrophic circulations that could enhanced dendrite growth, but 5.5 to 6 days out, will not be able to pinpoint the exact location. For now, anticipate north-central, northeast, and eastern Missouri to experience some travel issues due to winter weather. Once we get the mid-week anticyclone through here, we should have a better idea of how future systems could track, as well as a better idea of pavement temperatures and accumulating potential. There is a winter p-type bust scenario: The trough lifts northeastward quickly, and brings much warmer air, giving us only rain. && .AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/... Issued at 526 PM CST Mon Nov 24 2025 IFR/LIFR conditions will continue through the evening with rain tapering off near 03z and fog moving in overnight. Visibilities may get down to 1/4 SM again and ceilings will remain low through most of Tuesday morning. By late morning into the afternoon hours, northwesterly winds start to become gusty up to 30 knots and stay elevated through the evening. && .EAX WATCHES/WARNINGS/ADVISORIES... MO...None.
