KEY MESSAGES

- Areas of fog Wednesday and Thursday mornings.

- There is a 20% chance for advisory impacts from a wintry mix Thursday night into Friday.

- A more active pattern may continue into next week bringing additional opportunities for winter impacts over parts of the region. Predictability in impacts remains very low beyond Friday.

UPDATE

Issued at 731 PM CST Tue Mar 3 2026

Patchy dense fog is forming across parts of the area, with several locations reporting 1/4 mile to 1/2 mile visibility. Dew point depressions are near zero across much of the area, with nearly calm winds. These conditions are likely to continue through the early morning before southerly winds increase as we approach sunrise. Gradual improvements are expected from west to east starting just before sunrise.

..Uncertainty Late Friday into the Weekend

As a stronger wave ejects onto the Plains within southwest flow late Friday into Saturday, uncertainty only grows. First, ensemble members disagree around the timing of the wave. A little faster, and it may interact/phase with the first wave tracking through late Thursday into Friday. If it waits a little longer, these two systems may not interact at all. Second, ensembles show disagreement in the strength of the ridge over the southeastern US. Less ridging would mean a less north track, which would lower overall impacts for our FA. Intensity of the system is also unknown, with a large part of that hinging on if there is some sort of interaction between the two waves. Overall, there remains significant uncertainty in the location and intensity of winter impacts.

Beyond Saturday, ensembles are hinting at another wave or two as the flow becomes more zonal/northwesterly. Again though - there are large differences in the location/timing of each wave. Therefore, while a more active period of weather does look to be in store, details remain slim as to how conditions will evolve at any one exact location. Check back in the coming days for further details.

AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/

Issued at 525 PM CST Tue Mar 3 2026

The primary impacts to aviation this TAF issuance will be low ceilings and visibility restrictions. Fog is expected to fill back into the area tonight, with all TAF sites seeing a good chance for IFR to LIFR visibility. Currently, IFR to LIFR conditions are already being reported everywhere except KBJI. Heading into Wednesday morning, fog and mist persist through just after sunrise before winds pick up and drier air starts moving into the area.
