...Synopsis...
Along the southern periphery of a midlevel low tracking eastward
across southern Canada, a swath of strong deep-layer westerly flow
will overspread the northern/central Plains into the Upper MS
Valley. At the same time, a cold front will move eastward across the
region. Behind the front, 20-30 mph sustained west-northwesterly
surface winds (with higher gusts) will overlap the northern edge of
low boundary-layer RH across eastern MT into the Dakotas. While this
may lead to localized fire-weather concerns, preceding rainfall atop
already marginal fuels for some areas, and uncertainty regarding RH
reductions, limit confidence in the fire-weather threat --
precluding Elevated highlights at this time.
Ahead of the front from the southern Plains into the Midwest, a
tight pressure gradient beneath a strong low-level jet will yield
20-25 mph sustained southwesterly surface winds (with gusts upwards
of 35 mph). However, RH reductions generally appear marginal across
this corridor. Nevertheless, the strong/gusty winds may still
promote locally elevated fire-weather conditions where fuels are
receptive to fire spread.
