KEY MESSAGES

- Near critical fire weather conditions may occur each afternoon into this weekend.

- Well above normal temperatures are expected through early next week, with near record highs into the weekend.

UPDATE

Issued at 650 AM CDT Wed May 27 2026

The earlier activity that was more so focused in Valley City and SE ND has diminished. This leaves the later developing band of t-storms from near Cando thru DVL into Cooperstown area into eastern Barnes county left. At this time still favor a mid morning diminishing, but pops may be have to be extended beyond 14z for some areas.

UPDATE Issued at 332 AM CDT Wed May 27 2026

Ongoing showers and t-storms continue to re-develop in a corridor from Cooperstown thru Valley City thru SW Cass county ND with lighter activity into far NE SD. A few showers also forming northwest toward Devils Lake. Will maintain pops for this activity thru mid morning. CAMs indicate a weakening trend by then. Locally heavy downpours are occurring but look at personal wx stations show heavy rain pockets are small/isolated. Weak shear aloft and 20 kt 850 mb inflow keeping severe wx potential in check.

..Fire weather concerns through this weekend

Recent rains continue to expedite green-up, however as multiple dry/hot days have occurred there could be curing underway and considering there is still some dead grass/fuel loading we may see increasingly dry/critical fuels region-wide daily. As anomalously high temperatures continue at least parts of the region will continue to see daily RH values around or less than 25%, with NBM (and it's high bias) already showing values in the 20-25% range late week into this weekend. Due to the ridge axis aloft, winds aloft will be weaker in general, so this creates much more variable surface winds/gusts during periods of peak mixing reducing the predictability of RFW conditions. At the very least near critical fire weather conditions can be anticipated over at least parts of (if not much of the region) particularly late this week into the weekend.

AVIATION /12Z TAFS THROUGH 12Z THURSDAY/

Issued at 650 AM CDT Wed May 27 2026

T-storms in the Devils Lake airport area are anticipated to diminish in the 13-14z time period, but may last a bit longer. Cloud bases 8000 ft agl within the band of showers and t-storms that extend from DVl to west of Fargo. This activity should not affect KFAR airport TAF, but not a zero percent chance of this. Otherwise VFR today with mainly areas of high clouds, though clearing out of that later today and tonight. East winds 8 to 18 kts.
