.UPDATE...

Confidence for high winds for the foothills west of Billings has
increased and a High Wind Warning has been issued for areas of
Judith Gap down through Big Timber for 3 pm Monday through 9 pm
Tuesday with gusts 60-70 mph expected. For areas of Livingston
down through Nye, similar winds are expected 6 pm Monday through 6
pm Tuesday with the strongest winds being in the early morning
hours. Slightly less confidence exists for areas of Golden Valley
and Northern Stillwater counties. Cooler surface temperatures may
allow for an inverion to keep strong winds at bay, but there is
still uncertainty in surace tempertures Monday night and
especially Tuesday. Keep an eye on the forecast for updates.

.DISCUSSION...

The rest of today through Saturday...

Expect slick roads and sidewalks this evening into Monday morning
as wet pavement refreezes. Low temperatures tonight into Monday
morning will be quite cold again, especially east of Billings
where skies may remain clear for several hours overnight. From
Rosebud Co east, there is a 20-50% chance of lows below 0. Across
western zones where clouds move in more quickly, lows will range
from teens to low 20s.

Late tonight through Monday, a weak disturbance moves in from the
west, bringing a 60-80% chance of snow to the mountains, a 30-60%
chance of rain/snow showers to the foothills, and a 10-30% chance
of rain and rain/snow showers over the plains. Outside of the
western mountains and foothills, any accumulations look to remain
light, with generally a less than 20% chance of at least 0.1".
Over the western mountain, a few inches of snow are expected, with
a 40% chance of at least 6 inches over the highest peaks.

Late Monday into Tuesday, 700 mb winds increase to 65-75 kts out
of the west to northwest, which is favorable for strong winds
along the Harlowton to Big Timber corridor. A potential limiting
factor for strong winds at the surface driven by these 700 mb
winds is the recent snowfall and if/how much snow remains on the
ground into Tuesday. Snow on the ground will keep surface
temperatures lower, resulting in an inversion that limits stronger
winds at the surface. This will be something to keep an eye on
going forward. Currently, there is a 70% chance of gusts up to 60
mph near Harlowton and Big Timber and a 30-60% chance of gusts up
to 40 mph spreading out across the plains. For the Livingston to
Nye area, a decent gradient for gap winds is expected to set up
during the same time frame, although the 700 mb winds will have
less influence over this area.

Through the rest of the week, expect periods of breezy to strong
winds over the western foothills as 700 mb winds occasionally
increase to 50-60 kts. Otherwise, conditions trend warm and dry
through the end of the week under an upper level ridge. Highs
increase from 30s and 40s Monday to 60s and 70s for Wednesday into
the weekend. Archer

.AVIATION...

A period of light to moderate snow will likely impact the
mountains tonight into Monday morning causing periodic
obscurations of the high terrain. While confidence remains lower
regarding impacts to foothill airfields, KLVM does have a 30
percent chance of seeing brief reductions due to light snow.
Otherwise, VFR conditions will prevail.

Winds are expected to increase over the western foothills
(including KLVM, K6S0, and K3HT) tonight into Monday. Late Monday
into Tuesday, another period of strong winds is likely with there
being a 50 to 70 percent chance of seeing a 50 knot wind gust.
