KEY MESSAGES

- Next thunderstorm chance is Sunday night in southeast North Dakota. Severe weather is not anticipated.

UPDATE

Issued at 313 AM CDT Fri Aug 7 2026

Cold front located from near Bemidji thru Detroit Lakes to in between Wahpeton and Fargo. No precipitation has formed along the front as of 08z. However behind the front some mid level CU has grown in height and is producer a shower/t-storms just southwest of the radar site near Mayville. So will keep an eye on this. May need a few hour pop for this behind the front activity. From SPC meso page the activity is closely aligned to 850 mb cold front and an area of 35 kt 0-6 km shear.

..Shower and thunderstorm chances this afternoon and night

Models continue to show a narrow band of instability out ahead of the cold front this afternoon across southeastern ND into western MN. SPC meso analysis has about 500 J/kg, and with a few more hours of heating ML CAPE could get into the quadruple digits. Shear is around 30 kts, but a weak shortwave could get a few cells going that could produce some lightning, brief downpours, and even a bit of small hail or gusts to 50 mph. The cold front will drop through later tonight, with some additional elevated thunderstorms possible but most of the CAMs keep precipitation post frontal and unimpressive.

AVIATION /06Z TAFS THROUGH 06Z SATURDAY/

Issued at 1151 PM CDT Thu Aug 6 2026

A wind shift to the north is occurring at terminals early tonight as a cold front slides southeastward. A brief period of wind gusts will follow the frontal passage overnight, before winds die back down. The north to northwest winds will persist throughout the remainder of the TAF period, increasing again Friday late morning, with a couple of terminals acquiring gusts by afternoon. Before the frontal passage there is a brief window for LLWS at KFAR and KBJI during the first couple of hours of the TAF. Ceilings will remain VFR throughout the TAF period. Afternoon cumulus may develop Friday afternoon, therefore added in SCT050 at all terminals. Winds will decrease around sunset on Friday, becoming light and variable.
