.DISCUSSION...
Issued at 134 PM CDT Tue Jul 14 2026

...Synopsis...

Ridging will gradually flatten and move east today into Wednesday,
allowing cooler air to settle into the area, especially north of
Highway 200. Highs along the international border on Wednesday will
be near or just above 80 degrees, with a sharp gradient around the
Highway 200 corridor, then low to mid 90s to the south. There will
be a slight rebound of warmer temps further north on Thursday and
Friday as the western side of the ridge builds back into the area
through the weekend. Scattered showers and isolated thunderstorms
could form along the front and into the post-frontal environment
each afternoon today through Friday. Additional showers and
thunderstorms work back into the forecast this weekend, but will
depend on the timing of another slow moving cold front. This should
serve to bring temperatures back towards seasonal averages by the
middle of next week.

...Heat Impacts This Week...

Areas to the south of a slow moving cold front are expected to
remain quite warm through the end of this week. Afternoon temps in
the 90s will combine with dew points generally in the upper 60s to
low 70s to bring heat index values of around 100 degrees each
afternoon. The best chances to see these higher heat indices will be
in the southern Red River Valley and adjacent areas of southeast
North Dakota and west central Minnesota. Temperatures in the central
Red River Valley could climb back into the low 90s; however, lower
dew points should keep heat index values in the middle to upper
90s.

.AVIATION /06Z TAFS THROUGH 06Z THURSDAY/...
Issued at 941 PM CDT Tue Jul 14 2026

VFR conditions with winds mostly below 10kts for area now and
through tonight. Winds increase slight to 10-15kts for the late
morning/afternoon Wednesday with KDVL seeing the highest speeds
with gusts in the mid 20kts range. Smoke moving in from the east
is likely to impact KFAR so threw in a FU group at SCT250 to
represent this. Low confidence in smoke impacts at KBJI but cant
100% rule it out if the cold front stalls and lingers further
north.
