UPDATE

Issued at 449 AM CDT Tue Jun 9 2026

Warm front is lifting north/northwest is at 10z was located from near Lisbon to just south/east of Fargo up toward Fosston to Waskish. Scattered t-storms continue to develop on the edge of this warm front as it moves north, with new development taking place now near TRF and Fosston to Red Lake. Did update pops for this as the chc of storms farther south in west central MN has ended. Would expect chance of storms to exit 12z-14z.

Otherwise little change in SPC outlooks for today and Wednesday and overall thinking from previous AFD is valid.

..Wednesday's Severe Potential

Much of Wednesday's severe risk is dependent on how Tuesday/Wednesday morning evolves. With that said, the main upper trough tied to the upper low across Canada will swing through providing stronger forcing by afternoon. Potential for a spicy day does exist given the stronger mid-upper level winds, especially if instabilty is able to recover.

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/

VFR conditions should prevail across eastern ND and northwest MN tonight into Tuesday afternoon, with aviation impacts increasing Tuesday evening as a thunderstorm complex is expected to move west to east across the region. There is a 30% chance for severe wind impacts with this thunderstorm complex during the evening hours across eastern ND with timing later in northwest MN and more uncertainty. I introduced PROB30 for the severe wind impacts during the periods in ND when current guidance shows the best potential if this occurs.
