.DISCUSSION...
Today through Monday...

A much calmer weather pattern is expected over the next 7 days.
Temperatures will increase today and Wednesday into the 45-55
degree range as weak 500 mb high pressure blocking sets up over
the region. Temperatures increase further Thursday through the
end of the period as downsloping winds Friday transition to upper
level ridging by Saturday. Temperatures are expected to increase
from the 50s F Thursday through Saturday into the 55-65 degree
range Sunday and Monday. The next 7 days look dry with the only
chance for precipitation coming Friday as a shortwave trough moves
across the Canadian border. Precipitation potential from this is
limited with models indicating 0.10 inches of precipitation at
most.

The most impactful weather in the coming days will be increasing
wind potential for the foothills west of Billings starting
Thursday. The GFS is indicating that the Idaho Falls to Lewistown
pressure gradient will be around 9 mb Thursday morning but 700 mb
winds will be weak. Strong wind potential increases Friday through
Monday due to persistent high pressure in Yellowstone National
Park and elevated 700 mb winds. At this time, the chances for
winds to gust over 50 mph remain below 50%. Torgerson


.AVIATION...

MVFR to IFR ceilings and fog may linger over portions of SE MT
into the early morning, but overall trends will be for VFR
prevailing at most locations through the forecast period. Any fog
that develops will lift after 16Z. BT
