UPDATE Issued at 339 AM CDT Mon May 25 2026

DLH reached out to coordinate a SPS for near critical fire weather conditions where RH values were forecast to drop below 25 percent. This would be S Beltrami Hubbard and Wadena counties. DLH preferred SPS go thru 16z only so dayshift could monitor to see if RH values will reach that low. Did up pops a bit more in coverage in an area from mid and south RRV into MN Tuesday late aftn as signs point to a few storms forming along a northward moving warm front.

..Hot temperatures this week

Temperatures today are already in the upper 70s to lower 80s over many locations with additional daytime heating to go (will probably fall closer to the NBM 75th percentile at warmer locations). Seasonal averages are generally in the upper 60s and lower 70s. Monday through Wednesday will be even warmer as heights aloft rise in response to amplified ridging, with most locations at least in the upper 80s to lower 90s. Even 50th percentile values are within a few degrees of daily records on Monday/Tuesday and if any location were to fall closer the the 75th percentile daily records could be in jeopardy.
