.DISCUSSION...
Issued at 218 PM CDT Sat May 2 2026

An area of low pressure currently over southern Saskatchewan is
producing gusty westerly winds across the eastern half of the CWA.
The NBM probability of seeing gusts exceeding 30 mph is around 50
percent. KABR has exceeded 40 mph today. Because the winds are
stronger than expected, have blended in some of the NBM 90th
percentile for the rest of today, and actually through Monday.
Showers associated with the warm air advection is ongoing across
east-central ND, with a few CAMS suggesting a 20 percent chance for
light pcpn over eastern SD and western MN later this afternoon and
early evening.

Sunday should be dry with slightly cooler high temperatures in the
60s and low 70s. A stronger storm system, currently over southern
Nunavut, northern Saskatchewan, will slide southeastward throughout
Sunday into Sunday night, with increasing westerly winds moving into
the CWA after 3Z Monday. Half km winds off the GFS is 25 to 40
knots, with the highest values over eastern SD and western MN.
Again, blended some NBM 90th into the wind grids for Sunday night
and Monday. The cold frontal passage appears to drop south across
the CWA earlier in the day on Monday as the latest NBM MaxT on
Monday some 5 to 10 degrees colder then the previous forecast. The
cooler temperatures may offset the gusty northerly winds to limit
the overall fire weather potential. As of now, afternoon RH values
are in the 30 percent range. Winds will be gusty with the NBM
showing a 15 to 35 percent chance of gusts exceeding 40 mph.

Tuesday and Wednesday will feature mostly dry conditions with
seasonally cool temperatures with highs in the 50s. These readings
are 10 to 20 degrees below average for this time of year. Warmer air
should move into the area by the end of the work week with highs
reaching the 60s and 70s.
