UPDATE

Issued at 714 AM CDT Wed Oct 28 2026

Thru the night, updated SPS for patchy dense fog that does persist from Cooperstown to Lisbon/Gwinner and into parts of Cass county ND. Webcams show continued patchy/area fog coverage and thus SPS was issued and not advisory. This was done after coordination with BIS/ABR on fog. Seems as if earlier model data used for the grids from 00z were too wet this morning with shower chances as composite radar shows limited activity. barely worth of a 20 pop in the area from north of Bemidji to Hillsboro to Valley City where higher chances are. Devils Lake-Grand Forks-Roseau and north on the edge and precipitation chances are 10-30 percent. 06z SPC update for day 1 had marginal risk for severe storms skirting southern Wadena county, southeast Otter Tail, and Grant County MN. Based on instability forecasts do feel better severe chances is tied more to the slight risk area from SPC more toward the Twin Cities. Mentioned t-storm chances in HWO for that part of west central MN near marginal risk and it is in the forecast grids.

..Rain on Wednesday

The shortwave trough over Oregon quickly progresses across Rockies and into the Northern Plains overnight tonight into Wednesday morning and increasing forcing for ascent, moisture return, and some instability should support increasing rain coverage particularly in MN head of an associated frontal zone. There may be enough instability for some thunderstorm activity across west central MN which could contribute to localized higher rain totals. Strong/severe storms are not anticipated this far north with any potential for higher instability farther south. General totals will be lighter for most areas with probs for 0.1" and 0.25" high east of the RRV but probability in NBM/HREF for 0.5" lower (20-30% in our far east) and likely dependent on convective activity.

AVIATION /12Z TAFS THROUGH 12Z THURSDAY/

Issued at 714 AM CDT Wed Oct 28 2026

Typical early morning fashion where low clouds are mixed with some some clearing along the western edge of low clouds from Hallock to Grand Forks back to Cooperstown. Mid and high clouds mask the extent of low IFR ceilings around KGFK and KDVL. Clearing has been making progress eastward overnight as drier air at 850 mb moves in from the west on the south side of upper low in Saskatchewan. Timing of clearing as it works its way east this afternoon and coverage of IFR or LIFR ceilings this morning and early afternoon are a concern for TAF amendments.
