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 /06Z TAFS THROUGH 06Z SATURDAY/

Issued at 1137 PM CDT Thu Sep 24 2026

LIFR ceilings are developing across much of eastern ND and northwest MN, with IFR to MVFR visibility at times expected. VLIFR visibility (1/4sm) due to dense fog is more likely in the KDVL area of northeast ND where skies originally remained clear and better radiational conditions were in place during the evening hours. Fog should clear as low level winds increase to 10-15kt Friday morning, and IFR ceilings should eventually lift to MVFR. The persistent moist southerly flow pattern that has been in place in the lower levels will likely keep at least MVFR ceilings lingering into the afternoon and evening period Friday, with a medium chance for IFR ceilings to redevelop Friday evening or Friday night (better chances after the current TAF period).
