KEY MESSAGES

- Dense fog may impact the commute through Friday morning.

- Additional light rain is expected Friday night through Saturday night, and there is the potential for widespread soaking rain early next week. These rain events may impact outdoor activities and harvest.

..Rain Friday night and again Monday/Tuesday

Another quick moving shortwave coming through Friday night into Saturday morning will bring another round of light rain to the region. Probabilities of a tenth to a quarter of an inch of rain is over 60 percent, but drops off quickly for over half an inch. Some weak instability of less than 500 J/kg of MU CAPE could bring a few claps of thunder, but nothing else impactful. A stronger system moving in Monday into Tuesday could bring a more interesting setup, with some ensemble members showing portions of our forecast area in the warm sector with machine learning having a low probability for severe. Others have the track of the low a little further south and more stratiform precip setting up. While chances of severe are not high, there is over a 70 percent chance for an inch of rain or more over portions of the forecast area, so another round of soaking rain seems likely and will continue to message.

AVIATION /12Z TAFS THROUGH 12Z SATURDAY/

Issued at 644 AM CDT Fri Sep 25 2026

Fog and stratus continue to bring aviation impacts early this morning. VLIFR has been impacting KDVL for much of the night, and will likely continue for at least a few more hours. Elsewhere LIFR has been predominate, with a few pockets of slightly "better" IFR mixed in. Overall, the theme through the morning hours will be for gradual, slow improvement. This should result in MVFR during the afternoon hours. However, we will see a return to IFR Friday night as another system works its way into the area.
