.DISCUSSION...
Issued at 258 PM CDT Sat Jul 25 2026

...Synopsis...

Clusters depict strong agreement in the synoptic evolution
through midweek before uncertainty increases with the placement
and magnitude of the ridge centered over New Mexico. By Thursday
ridge rider activity could resume though most machine learning
guidance keeps activity more along the high plains rather than
this far east, something to monitor. At the same time we above
normal temperatures continue through much of the workweek with
widespread upper 80s to low 90s into next weekend, several days
will feature highs in the mid to upper 90s primarily in the Red
River Valley. Along with the hot temps will be low RH (30%) that
could lead near critical fire weather at times through the
week.

- Severe risk Saturday/Sunday

A marginal risk is in place across far northwest/north central
Minnesota this afternoon with a slight risk across all of
northwest Minnesota Sunday. For todays threat the risk is quite
conditional with a boundary draped NW to SE across North Dakota.
This will continue to move east across the state this
afternoon/evening will the storm risk on the northern periphery.
A stout post sunset cap will favor any storms to be elevated
with hail as the primary threat. Should storms root atop the
inversion hail to the size of golf balls could be expected but
more likely perhaps is a few virga showers as skinny cape
profiles will be subject to dry air entrainment limiting and
updrafts potential to grow through the hail growth zone.

Similarly pessimistic about Sunday as the forcing will be weak
and convective temps anywhere from 95-105. Hitting anything
above 100 is far from a guarantee so best chances for storms
will increase will eastward extend further away from the 850
thermal ridge. Should convective temps be reach surface based
storms become likely with initially discrete airmass convection
organizing into bowing clusters that track southeast. Winds up
to 60 mph and hail to the size of golf balls are possible.

- Heat Impacts

Our run of 90 degree days in July continues to end the month
with 90s possible if not likely each day through next Saturday
within the Red River Valley. Heat headlines have been posted
through the next 2 days for much of the area with a an extreme
heat warning in effect tomorrow for the central and southern
valley as heat indices may locally climb as high as 110. Through
the rest of the week the well mix boundary layer and warm temps
will routinely lead to highs in the upper 80s to low 90s and
Min RH around 30%. This will warrant at least marginal fire
weather concerns most days given the state of seasonally dry to
very fuels. Combine this with the potential for one or two days
to see afternoon winds reaching 20+ mph and near critical
conditions are possible. Rain looks to be a low probability once
again through the coming week possibly further
degrading/expanding the existing drought conditions across much
of the area.

.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...
Issued at 1101 PM CDT Sat Jul 25 2026

VFR conditions will prevail for the TAF period with generally light
winds under 10 knots across the region. While the overall prevailing
wind should theoretically be from the east to southeast through late
tomorrow afternoon, the light wind field brings high uncertainty on
if this actually occurs, hence the long durations of VRB in the
routine TAF issuance. This will change late tomorrow afternoon into
the evening/overnight period as a front pushes through the area and
shifts wind direction to northwesterly. A modest increase with wind
speeds is expected to push sustained winds to 10-12 knots.

Showers and thunderstorms may develop tomorrow afternoon, with the
highest chances in portions of northwest Minnesota closer to BJI.
PROB30 groups were introduced at BJI for the 06z TAF issuance to
cover this and may need to be expanded depending on trends.
Thunderstorms should be over by the end of the TAF period for all
TAF sites.
