Relative humidity values will rise as a front moves through the
region. Showers will likely bring increased wind gusts between
40-50 mph, but this will occur simultaneously with relative
humidity values pushing past 50%. There may be a period over the
next hour or two of some locations hitting red flag criteria,
however widespread impacts have ceased.

  through the weekend with a 20 percent chance for critical
  fire weather conditions on Friday.

.DISCUSSION...
Issued at 221 PM CDT Thu May 7 2026

...Synopsis...

Northwesterly flow aloft continues through tonight and tomorrow,
with the next shortwave digging down Friday night into Saturday.
The northwesterly flow aloft returns for Sunday and Monday
before another shortwave pushes through the Northern Plains
Monday night and Tuesday. After this shortwave, ensemble members
are all over the place with some clusters pushing ridging into
the Plains and other clusters keeping us in northwesterly flow.
Predictability is low although the ECMWF EFI does show our
colder temperatures signal transitioning over to warmer than
average by days 6 and 7.

...This afternoon's near critical fire weather...

Temperatures finally not quite as cool as they have been this
week and most spots have risen into the 50s. With dew points in
the teens to low 20s, relative humidity values have dropped into
the 20 to 30 percent range for the most part. Winds are mostly
under 15 mph although a few spots are gusting up to around 20
mph. SPS for near critical fire weather conditions continues to
seem good, and the low RH values will continue into this evening
before temperatures start to drop.

...Tomorrow and beyond fire weather concerns...

Similar RH values are expected for tomorrow afternoon, and there
will be more of a pressure gradient as a surface trough moves
through. While winds look higher than today, there is only
around 30 kts to mix down and not much in the way of pressure
rises. The 50th percentile of NBM has some 25 mph sustained
winds in east central ND, but may be due to the NBM's bias in
that area. The HREF joint probability for winds over 25 mph and
RH values under 25 percent doesn't have much. Dropping the winds
threshold down to 20 mph gives us some low chances for critical
fire weather conditions on the MN side, around 20 percent.
Definitely could see critical to near critical fire conditions
for tomorrow afternoon, but not confident enough to go with a
watch at this point. Still breezy into Saturday, but slightly
cooler temps should bring higher RH values and there will be a
low chance for showers. Less wind and similar RH values for
Sunday.

&&

.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
Issued at 1119 PM CDT Thu May 7 2026

VFR conditions will prevail for the TAF period. Winds will
remain light and variable overnight, becoming northwesterly to
northerly through the day tomorrow. Winds will peak early to mid
afternoon with sustained winds in non-tree landscapes generally
15-20 knots, gusting to 30 knots, with more tree filled areas
generally 10-15 knots, gusting to 20 knots. Showers will move
through late tomorrow afternoon, potentially impacting TAF
sites, although rainfall rates should be light enough to avoid
any visibility reductions. The main concern from any showers
will be changes in wind direction and speed beneath these
showers as we remain fairly dry near the surface. These will
work their way southeastward and exit the region after the TAF
period ends around 09-12z Saturday morning.
