.DISCUSSION...(This Evening Through Friday)
Issued at 118 PM MDT Fri Sep 20 2024
Fast moving upper trough will support a strong cold front into
the region tonight. Warm SW flow has allowed for much warmer conds
today across the region with dry conds continuing. Strong cold
front will move through the region later tonight, supporting
breezy NW winds, esp in the lee of the BH where adv level winds
are expected for period. Staunch CAA and pressure rises should
allow for a few gusts to 50 mph, esp with the cold front. There is
a slight chance for a few post frontal showers near the ND border
late tonight as some weak lift and elevated moisture advects
across the region. Much cooler Saturday and Sunday when temps will
only top out in the 60s and low 70s most places with lows in the
30s and 40s. Some frost will be possible Sat night across the NW
half, where skies remain clear. Secondary impulse will skirt south
of the area, Saturday night. However, this system has shifted
further south on model progs with dry conds expected in the FA
now. Upper ridge will slowly build back into the region next week
with above normal temps, and mainly dry weather. There is an
outside chance for a few showers Monday with a passing upper
trough. However, moisture will be very limited with this system.
