UPDATE

Issued at 716 AM CDT Wed Jun 10 2026

Last of the overnight convection existed the eastern fcst area around 6 am with last of the rain exiting Baudette area currently. Satellite shows some clearing behind this system, but then as a cold front moves in from the west do expect an increase in cloud cover and chances for showers and t-storms into eastern North Dakota and into western Minnesota late morning into early afternoon. Position of cold front looks to be just near or east of the immediate Red River valley at 18z and at this time is when should have sufficient instability (2000-300 j/kg MU CAPE and 50 kts 0-6 km bulk shear for development of an area of thundersotrms, some severe. These storms would move out of the area by 6 pm.

..Heat-related impacts this afternoon

As of writing this discussion, heat indices within portions of the Red River Valley are in the upper 90s nearing 100F. Heat indices nearing or just touching 100 F combined with wet-bulb globe temperatures into the low 80s as well as Heat Risk of Moderate to Major (levels 2 and 3 out of 4) within the Red River Valley pushed the need for an Advisory.

These conditions will be impactful to those more sensitive to heat as well as those who are working/exercising outside as well as to those without a means of cooling.

Heat impacts end after sunset this afternoon.
