.DISCUSSION...
Issued at 326 AM CST Sun Nov 30 2025

...Synopsis...

Sfc high pressure was over north central Montana at 08z. Sfc
temps in this area where deep snowcover exists and winds are
light are -20F below (Havre MT). High pressure will slide
southeast today into eastern SD by 00z. Decreasing 925-850 mb
moisture going thru today. Satellite shows stubborn clouds
around still and upstream into eastern Sask/Manitoba. But also
clearing areas. Will expect this cloud and sun mix today. Light
winds tonight, turn southwest tonight. How low temps go will
depend on cloud cover with potential for widespread single
digits below zero readings.

Going thru next week the weather pattern will continue to show
broad 500 mb trough over central Canada with several short waves
moving southeast across the area, but each one has limited
moisture and 24 hour probs of more than 1 inch of snow remaining
10 pct or less thru Friday. One wave passes thru Tuesday late
into Tuesday night, then what could be the coldest airmass so
far Wednesday into Wednesday night as high pressure this time a
bit closer to our area Wed night and with this better clearing
chances. Another clipper system Friday or Saturday. Probs using
mean ensembles from ECMWF, GFS, GEM and NBM indicate Saturday
24 hour snowfall chances of more than 1 inch 20-30 percent but
probs of 3 more than inches at that time period 10 percent or
less.

.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...
Issued at 1136 PM CST Sat Nov 29 2025

Mostly MVFR to VFR, and upstream observations show more of that
mix, along with a few spots with IFR ceilings and flurries for
good measure. Most sites should have at least a period of MVFR
ceilings by morning, with flurries on and off mostly in the
3-5SM range if any restriction at all. Some improvement to VFR
is possible at all sites during the day tomorrow, with rising
ceilings and possibly a few breaks in the clouds by the end of
the period. North to northwest winds at 10 to 15 kts will
continue that direction overnight before shifting more to the
west then southwest by late tomorrow.
