.DISCUSSION...
Issued at 255 PM CDT Wed Jul 16 2025

...Synopsis...

High pressure and a cooler air mass will be in place across the
region into Thursday allowing for mainly dry conditions and
clearing skies. As the area of high pressure moves off to the
east a more zonal flow pattern sets up into Friday with an
embedded shortwave trough moving through the region. This wave
could spread chances for showers and storms across the area late
Thursday night into Friday as WAA sets up across the northern
Plains. Instability will be somewhat limited around 1000 J/kg and
with stronger instability situated further south of the
forecast area, with ok deep layer shear so a stronger storm or
two may be possible. However widespread strong to severe storms
is not anticipated Friday.

A larger trough then begins to develop into the Pacific
NW/Canadian Rockies by late in the weekend with upper level
ridging into the central/eastern US allowing for more of a
southwest flow pattern across the northern Plains into Sunday,
with the troughing becoming elongated into central Canada toward
early next week allowing the southwest flow pattern to continue
across the region. This will allow for a warmer, more active
pattern to set up across the area for the latter portion of the
weekend and into next week. An initial shortwave will lift
northward through the region Sunday into Sunday night, with a
secondary wave moving through the area again Monday, with
additional energy lifting out of the base of the upper level
trough through mid-week. More widespread storm chances will
return to the area with these two initial waves lifting through
the region Sunday into Monday with increasing instability and
deep layer shear. ML progs indicate heightened probabilities for
severe weather across much of ND and the FGF forecast area from
Sunday through Tuesday at this time.
