.KEY MESSAGES...

- Near critical fire weather conditions are expected this
  afternoon in southeastern North Dakota.

- Critical fire weather conditions could develop in northeastern
  North Dakota Sunday afternoon, and a Fire Weather Watch is in
  effect. Near critical conditions in southeastern North Dakota.

.DISCUSSION...
Issued at 130 PM CDT Fri May 1 2026

...Synopsis...

North to northwest flow continues through the forecast period, with
several shortwaves traversing the flow into the Northern Plains and
Upper Midwest. Rain chances will be minimal through Sunday, with
only a scattered shower or two possible in response to a very weak
shortwave. Temperatures gradually warm today through Sunday,
bringing afternoon highs into the 60s for most areas this weekend. A
slightly stronger shortwave and upper low will move across
northeastern North Dakota and northwest Minnesota heading into
Monday; however, the latest ensemble trends continue to show better
rain chances retreating further northward. At this time, there is a
50 percent chance for 0.10" of rain along the International Border
near Lake of the Woods, with lower chances further south and west.

...Fire Weather Concerns...

Minimum RH values will hover in the 25-35 percent range today
through Sunday. Warmer temperatures return for the the weekend as
afternoon highs climb into the 60s across eastern North Dakota and
west central and northwest Minnesota. Winds are expected to remain
generally light today and Saturday, with an increase in winds for
Sunday. These slightly higher winds will bring a chance for near
critical fire weather Sunday afternoon and evening. A cold front
brings rain chances back into the area on Monday, mainly for
northwest Minnesota and parts of the northern Red River Valley.

&&

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1222 PM CDT Sat May 2 2026

The only aviation impact for the TAF period should be mainly
wind shifts that will occur. This afternoon, southwest to
westerly winds will shift to northwesterly as a cold front
pushes through the area. Showers may accompany this but cloud
bases are very high due to dry air so precipitation is unlikely,
and thus aviation impacts are unlikely even if we see any
rainfall. Winds will diminish after sunset, remaining around 10
knots through midnight with eventually sub-10 knot winds
expected thereafter. As the sun rises tomorrow, speeds will
increase once more, particularly closer to the end of the TAF
period where sustained winds will likely exceed 12 knots.
