..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.

Issued at 1250 AM CDT Wed Jun 10 2026

A line of severe thunderstorms continues to push slowly eastward early this morning and has brought wind gusts to 50 knots earlier at KDVL. The strongest part of the line extends from north of Valley City southeast to near Lidgerwood. This part of the line is moving more northeast than east and has produced gusts to 60 knots over the last few hours. The line should move through the GFK area over the next hour or so, KFAR and KTVF in the 07-09z time frame and KBJI in the 08-10z time frame. Winds ahead of the line continue to be from the southeast with gusts to 20 to 30 knots. A low level jet remains in place as well, mainly affecting KBJI over the next few hours with LLWS. Storms exit to the east before daybreak with a break in activity into at least mid-morning before additional showers and thunderstorms develop. Thunderstorms may again be severe during the late morning and afternoon hours. Most of this activity should remain east of KDVL.
