Discussion...with winds remaining breezy overnight across central
Idaho (specifically the Camas prairie), and across west central
Montana (including the Missoula/Bitterroot valleys), temperatures
have been fairly mild. Cooler valley temps can be found
immediately along The Divide, however, which will bring about a
fairly chilly morning. Otherwise, with precipitation staying east
of The Divide, today should be a mostly pleasant day across the
region with partly cloudy skies.

Forecast models have been slowly backing off on the coldest of
the Canadian air that could puddle in valleys overnight
tonight. Even so, we have elected to keep the freeze watch going for
the Missoula/Bitterroot valleys, just in case some locations
still dip into the low 20 degree range for Monday morning. In any
case, it would be best to prep for cold temps should irrigation or
vegetation become susceptible.

A slight warming and drying period is expected to begin Monday and
Tuesday as a weak ridge of high pressure begins to rebuild over
the region. Temperatures will run slightly above normal during
this time. The ridge will briefly breakdown on Wednesday and
Thursday, which will allow temperatures to run closer to normal.
A few showers will also be possible, especially in central Idaho
and southwestern Montana, however most of US will just see an
increase in clouds and "cooler" temperatures. The ridge will
rebound for the rest of the week through next weekend. After next
weekend, long range forecast models indicate another shortwave
trough entering the area, bringing more showers and breezy


Aviation...lingering breezy east-northeast winds up to 15 knots will
continue to affect kmso through the mid-to-late morning hours
before steadily decreasing. With little precipitation expected
today, the northern rockies will see pleasant flying conditions
through Monday.

Montana...freeze watch from late tonight through Monday morning
Missoula/Bitterroot valleys.
