KEY MESSAGES

- Temperatures will cool into the 40s for the weekend, closer to seasonal averages.

- A warmup to above normal temperatures early next week then cooler again by the end of the week.

SHORT TERM /THROUGH TONIGHT/

Issued at 140 AM CST Sat Jan 10 2026

Water vapor imagery and upper level analysis continue to show a high amplitude ridge axis over the west coast states with a longwave trough from the upper Mississippi valley, southwest into New Mexico. Several waves of energy are embedded in this in phase trough with the northern shortwave swinging southeast out of the northern plains into the upper Mississippi valley and the southern energy shifting east over the central and southern plains. Light rain and lower ceilings were occurring across west central MO into central and northern MO as this shortwave pushes through. Most of the precipitation will remain across central MO and points northward with a few sprinkles possible further south. A few snowflakes may mix in with the light rain in central MO with no accumulation or winter impacts expected. Temperatures were still in the low to mid 40s across the area as of midnight. Lower clouds will continue to push into the area behind a front and ahead of the mid/upper level shortwave axis the remainder of the overnight.

Today: The cloud cover will likely not clear out until mid morning in the west, midday along the US 65 corridor and by mid afternoon in the east. Precipitation chances should generally come to an end prior to sunrise this morning. Colder air will begin to advect into the area behind the front and upper wave and we'll see northwest to northerly gusts up to 30 mph at times today. Temperatures will be cooler today than we've had with highs generally in the 40s.

Tonight: A secondary strong northern stream shortwave will dive southeast into the upper Great Lakes and Ohio valley tonight with the back edge of this shortwave over the northeast portion of our CWA. The air mass moving in during the day will be quite dry, so precipitation chances will be quite limited. Some of the CAMS are spitting out very light precipitation which would be snow flurries if it develops and likely to only affect far eastern portions of the CWA. Lows tonight should dip back into the mid 20s for most locations.

LONG TERM /SUNDAY THROUGH FRIDAY/

Issued at 140 AM CST Sat Jan 10 2026

The cooler air mass will continue through the remainder of the weekend. Despite plenty of sunshine expected on Sunday, highs are only expected in the upper 30s to mid 40s with lows Sunday night from the mid 20s to around 30.

The overall upper pattern doesn't look to change too much through the upcoming work week with a large amplitude ridge axis remaing out west and northwest flow from western and central Canada into the plains to the OH/TN valley.

Early in the week, we'll see the cooler air mass shift eastward and a return to low level warm advection. This will bring temperatures back to above normal into the 50s and 60s for Monday and Tuesday.

The next shortwave embedded in the deep northwest flow will arrive by midweek and bring about another cooldown to the area. With Gulf moisture remaining to the south and a dry airmass in place over the area, precipitation chances and QPF with any precipitation look to be on the low side at this point. Temperatures return to more seasonal values for the end of the week with 40s for highs and generally 20s for lows.

AVIATION /06Z TAFS THROUGH 06Z SUNDAY/

Issued at 1115 PM CST Fri Jan 9 2026

For the 06z TAFS, currently have mid level VFR ceilings over the area (as of 05z). A frontal boundary and upper shortwave will push through the area during the period. Radar was showing some light rain occurring over west central MO, mainly northwest of the TAF sites. Will see the ceilings drop into MVFR as the front moves through the area along with northwesterly winds becoming gusty with some gusts of 20 to 25 kts possible. MVFR ceilings will likely hold on until the mid level shortwave moves through around mid morning at JLN and midday at SGF/BBG. Gusty winds will continue throughout the afternoon before diminishing towards sunset. VFR conditions are expected after the clearing near midday.
