.KEY MESSAGES...

- Showers and thunderstorms are likely Monday. A few storms
  could become strong, with the primary hazards being lightning
  and small hail.

&&

.UPDATE...
Issued at 1225 PM CDT Sun Jun 14 2026

temperatures in the 60s. Northwest winds will continue at 10-15
mph, with a few gusts to near 25 mph.

.DISCUSSION...
Issued at 222 PM CDT Sat Jun 13 2026

...Synopsis...

A persistent and strong upper low is expected to remain in place
over the Hudson Bay region through much of next week. Occasional
shortwaves traverse the upper flow into the Northern Plains, with
chances for showers and thunderstorms nearly each day next week.
Ensemble guidance shows pattern confidence; however, timing is less
certain due to shortwave speed and strength. At this time, the best
chances for precipitation will be Monday and Wednesday, but there
are lower chances nearly each day. Looking into Monday, there is a
chance that a few storms could become strong as there will be enough
MUCAPE in the presence of strong lapse rates to allow a mention of
small hail.

&&

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 1225 PM CDT Sun Jun 14 2026

northwest at 10-15 knots, with gusts ranging from 20-30 knots.
Look for gusts to diminish late this evening at all TAF sites.
Heading into Monday morning, winds shift to the west, then
southwest at 10-15 knots.
