SHORT TERM /THROUGH WEDNESDAY/

Issued at 116 PM CST Tue Jan 27 2026

Water vapor imagery and upper level analysis show an amplified ridge axis over the great basin into the southwest U.S. with a storm system pushing into the west coast. East of the ridge, a large area of low pressure remains over southern portions of Hudson Bay into Ontario an Quebec with cyclonic flow covering abouut half of the CONUS. A shortwave over the Rockies had some mid/high level cloud cover which was spreading east into the plains and mid Mississippi valley. At the surface, a cold front was pushing south into the forecast area and should switch our wind to the northwest then north this afternoon and early evening. Temperatures have warmed into the upper 20s to low 30s across the area.

Tricky short term forecast for tonight. The mid/upper level cloud cover is expected to spread east into the area this afternoon and evening then continue into parts of the overnight. Last night the warm air advection won out against the snow cover and kept temperatures steady or even slowly rising through the night. Am not expecting the same scenario tonight. Currently dew points were in the teens across the area which will be our cross over temperature during the warmest part of the afternoon for radiation fog development potential. In support of fog development we will have temperatures dropping below the cross over temperature tonight into the single digits. Also, we will have surface high pressure moving into the area which will keep winds light and variable and thirdly we will probably have some snow melt adding moisture in the boundary layer. Working against fog development will be the potential for mid/high level cloud cover. Have added some fog to the forecast, generally in the 2-5 mile visiblilty range for now, but this may have to be adjusted downward if cloud trends start decreasing. The main are of expected lower visibility will be along and south of the U.S. 60 corridor in southern MO.

Wednesday: In the wake of any morning fog, we should see plenty of sunshine and temperatures risingn back into the mid 30s for highs which will cause more snow to melt across the area.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/

Issued at 116 PM CST Tue Jan 27 2026

Another shortwave will push into the plains on Wednesday night which will help to develop an area of low pressure at the surface over the plains into the mid/lower MS valley. There will be a frontal boundary draped west to east across southern MO or northern AR. We may see fog develop again during the overnight hours Wednesday night across southern MO. As the shortwave moves across the area late Thursday into Thursday night, there may be enough energy and moisture for a few snow showers on Thursday night(pops at this time are 20% or less).

Another Arctic Blast: A stronger shortwave on Friday into Friday night will usher in another Arctic air mass into the region with highs only in the low to mid 20s Friday and lows dropping into the single digits above and below zero again Friday night. Wind chills Friday night will be in the single digits to teens below zero. This may flirt with Cold Weather Advisory Criteria Friday night. Highs on Saturday will be in the teens to low 20s with lows Saturday night back in the single digits.

We start to rebound back into the 30s for highs on Sunday as the high pressure system moves to our south, with possibly upper 30s to low 40s by Monday which would be closer to seasonal norms.

AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/

Issued at 1116 AM CST Tue Jan 27 2026

For the 18z TAFS, a cold front was just to the northwest of the area and winds were starting to veer around to the west, eventually becoming northwest this afternoon after the fropa. An upper level shortwave will push through the area this evening/tonight with mid/high level cloud cover increasing over the area. Temperatures should drop below crossover temperatures tonight with the potential of some radiation fog developing if we can clear out the mid/upper level cloud cover. For now, have added 5sm with a 4 hour 2sm tempo group at the TAF sites to account for the fog potential. Should we lose the cloud cover sooner, the visibility may need to be adjusted with future forecasts.
