SHORT TERM /THROUGH SUNDAY/

Issued at 252 AM CST Sat Dec 6 2025

There is a Dense Fog Advisory in effect until 10 AM for areas along and west of Highway 65. Dense fog is expected to develop this morning and visibilities could drop below 1/4 mi at times. Areas near central MO have the possibility of seeing freezing fog as their temperatures will hover near freezing early this morning. If freezing fog does occur, elevated surfaces may become icy, travel with caution.

The rest of today will feature partly cloudy skies with highs reaching the lower 50s and light southerly winds just near 10 mph. Another shot of cold air will arrive overnight as a cold front moves through. Lows will slowly drop into the mid 30s tonight.

Winds turn northerly and become gusty by Sunday morning. Winds will gust up to 25 mph by Sunday afternoon. As mentioned in the previous discussion, there is still a slight chance (10-15%) of drizzle following the frontal passage on Sunday morning. This is mainly for areas along and north of I-44. The RAP shows that low-level moisture is expected to be over 90%, there will be plenty of lift from the passing front, and cloud ice will depart as the front pushes southeast. We haven't completely ruled freezing drizzle out of the forecast for Sunday morning. It sill appears that locations closer to central MO have the highest chance to see freezing drizzle if it does occur. Right now, hourly temperatures hover around 31 to 33 degrees from 7 AM to 10 AM Sunday morning up there. The confidence in freezing drizzle occurring is still low at this time due to that two degree temperature spread. The formation of freezing drizzle will be dependent on how quickly temperatures begin to drop behind the front. No other wintry accumulations or impacts are expected at this time.

The rest of the day Sunday will be cloudy, breezy, and chilly with temperatures only reaching the mid 30s by the afternoon. Sunday night will be cold with lows in the upper teens to lower 20s.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/

Issued at 252 AM CST Sat Dec 6 2025

A surface high starts to build in to our north to start the next week. Southerly flow returns on Monday and high temperatures slowly warm back up for the middle of next week. Highs on Monday will be in the 40s while Tuesday and Wednesday could feature highs in the low to mid 50s. Towards the end of the forecast period, we have a couple of shortwave features that will past just to our north. These shortwaves will bring us a couple of weaker fronts by mid-week. Right now, there isn't precipitation expected with those fronts. One front will move through on Wednesday and another one will move through on Thursday night. This means that our wind directions will be erratic for the latter half of the week and will switch between southerly and northerly each day and each day will feature partly cloudy skies. Highs on Wednesday and Thursday will be similar in the upper 40s to low 50s with wind gusts near 20-25 mph due to the shortwave activity. Highs by Friday will be a bit cooler in the 30s due to the front that moves through on Thursday night.

AVIATION /12Z TAFS THROUGH 12Z SUNDAY/

Southerly winds will remain light less than 10 knots. A cold front will move through late tonight turning winds out of the north by Sunday morning and bringing MVFR ceilings back to the area.
