.DISCUSSION...

Winds are going to tend to vary this afternoon and evening in the
proximity of the wildfire as a frontal zone is stalled nearby and
will tend to shift back and forth. This will result in winds
shifting from the southwest to northeast but could vary off and on
until Sunday when the main cold front pushes through the region
and strong northwest winds arrive. The best chances for rain
showers (lower coverage of thunderstorms) is later this evening
after 10 PM with showers continuing into Sunday. Outside of
isolated/localized higher totals where thunderstorm activity
tracks, most rain totals in the area of the wildfire will tend to
be lighter, with a 50% chance for greater than 0.25" of total
rainfall. The most organized/heavier rains will be in northeast ND
or near the US/Canada border.
