UPDATE

Issued at 308 AM CDT Mon Jul 13 2026

Upgraded the red flag watch to a warning for parts of northwest Minnesota (Park Rapids to Bagley to Roseau and east) where the Minnesota Intragency Fire Center is requesting red flag warnings when winds are 15 mph or higher and RH values are less than 35 percent in the forested locations.

..Heat Impacts May Linger

Heat impacts may extend into Tuesday / mid week in southeast ND and west-central MN. This will depend on how far an eventual dry cold front moves through late Monday into Tuesday. It is possible, additionally heat impacts (and subsequent headlines) may linger in these areas into mid week.

While the hottest temperatures aloft will moderate next week beyond Monday, there is a cluster of ensemble guidance that still keeps anomalously high temperatures aloft within the Dakotas and Minnesota through Friday. This includes some guidance suggesting 850mb of at least 90th percentile compared to climatology.

This would introduce potential for long duration heat impacts. And while heat indices may not reach 100F, heat indices well into the 90s, high to extreme wet bulb globe temperatures, as well as poor overnight recovery is maintaining HeatRisk in the Major to Extreme categories within southeast ND and west-central MN through at least Thursday.

Should this heat linger through the work week next week, this would be unusually long heat wave for our region. This may necessitate the need for extension of Extreme Heat Warnings next week.

This will also have implications on rapidly developing drought within the region, of which the CPC has outlooked our region for this potential.

Additionally, this would serve to dry out fuels for subsequent fire conditions. This is something we will be on the look out for.
