Previous Discussion...
Parade of Pacific systems continue to move through the area early
in this period.

Next system crashing into western Canada this afternoon will move
to our north and bring milder air into the area especially
Saturday. This system will bring extreme winds to the Rocky
Mountain Front of Montana, but clouds and lower lapse rates will
keep much of these winds from reaching the ground in our CWA. The
Little Rocky Mountains will experience the highest winds prior to
a cold frontal passage Saturday Night, but winds did not look
strong enough for a High wind Watch. Highest wind gust may be 50
mph Saturday morning, but that was it. Did increase winds a bit
from what the model blend or highest model produced (as they tend
to be a tad too low). Otherwise, temperatures will be knocking at
the door of records (Record high for Glendive is 57).

A cold front will drop into the CWA Saturday Night and bring
temperatures back closer to reality Sunday with highs in the 30s
and 40s. But Monday will be closer to normal with highs in the
20s and 30s.

Later in the week, the upper trough that brings us the cold Monday
will shift to our east, putting northeast Montana under a strong
NW flow. A couple of fast moving systems could bring a quick burst
of snow/mixed precip. TFJ

.AVIATION...
VFR.

NW winds will continue to diminish and should generally be 10 kts
or less late this evening. Any low clouds at KSDY and KGDV will
move east as well.

Next system will move in Saturday with winds being the main issue.
