.DISCUSSION...
Issued at 1252 PM CDT Tue Apr 28 2026

...Synopsis...

Surface analysis this afternoon shows a surface low working its
way away from our area, diminishing the pressure gradient and
thus allowing for winds to diminish. Afternoon cumulus has
developed but will remain benign as dewpoints remain fairly dry.
This will diminish after sunset with winds becoming more light
and variable.

The remainder of the week will be mostly rinse and repeat with
temperatures in the 40s and 50s with generally light winds and
dry conditions. Temperatures look to increase this weekend,
which should cause relative humidity values to become lower.
However, there is no strong signal for wind and green up is
ongoing, so the probability for critical fire conditions is low.
Having said that, near critical fire weather conditions may
arise with minimum RH values around 20%, even without wind.
Regardless, this remains the only weather impact for the
forecast period.

.AVIATION /00Z TAFS THROUGH 00Z THURSDAY/...
Issued at 624 PM CDT Tue Apr 28 2026

VFR conditions are expected to prevail through the TAF period
across eastern ND and northwest MN, with periods of 5-10 kft agl
stratocumulus through the TAF period. Northwest winds should
become light (5kt or less) and more variable after sunset as
surface high pressure is in place. As daytime mixing increases
northwest winds should increase again back to 12-15kt Wednesday,
with periodic gusts to 20kt. The strongest winds within the
mixed layer are below 25kt across the region Wednesday, so gusts
30kt+ are not expected at KGFK.
