DISCUSSION

Issued at 349 AM CST Sun Nov 8 2026

Broad high pressure continues to dominate the weather front across the lower 48 leading to tranquil weather conditions. Good radiative conditions has allows patchy fog to develop generally confined to low lying areas. Because the fog is expected to remain patchy, have not considered a dense fog advisory. Any fog is expected to burn off within a few hours of sunrise. A weak cold front associated with a low pressure system over Ontario is expected to approach from the north today. A few high clouds may filter into northern Missouri this morning, but as they continue to push southeast in northwest flow they encounter more dry air limiting cloud cover today. As mixing increases today, westerly-northwesterly winds will mix-down from aloft effectively washing out the boundary. With 925 hpa temperatures nearly 10 degrees C warmer than yesterday and mostly clear skies, expect a larger diurnal curve today with high temperatures in the 60s F.

Surface ridge reorients itself over the Tennessee River Valley tonight into Monday leading to southwest flow across the region leading to a gradual warming trend Monday. Another weak cold front approaches from the north on Tuesday leading to potential slight cooling across northern Missouri.

A series of waves building southeast attempt to phase into a deepening trough mid-week. Depending on how quickly this occurs, portions of central Missouri may see the potential for rain showers along a cold front building south. Cooler conditions follow late week with the potential for more frost/freeze conditions Friday and Saturday mornings. Temperatures trend back above seasonal norms late next weekend as trough along the east coast shifts east and upper level ridge builds into the central US.

AVIATION /06Z TAFS THROUGH 06Z MONDAY/

Issued at 1118 PM CST Sat Nov 7 2026

VFR continues to prevail at terminals. Patchy fog has begun to develop across the forecast area, but with high clouds approaching from the north and surface winds remaining stronger around 5-10 kts, still some uncertainty on the development of BR/FG at downtown terminals overnight (5-10% chance of < 5 SM), and thus have continued to leave out mentions. Still left mentions of BR development at KSTJ, with the continued idea that low- lying areas and river valleys will be the most susceptible to overnight BR/FG development. Still looking at a wind shift out of the NW tomorrow by 15-18z with the passage of a weak cold front.
