Update
Update again to refine temperature forecasts for not as cold in
the west and colder spots in the east. Waiting for southerly
winds to begin kicking in along the western areas and foothills to
begin mixing but this process is being delayed by the strong
surface high formation under the clear skies and deep snow in
southeast montana. Borsum
updated forecast to lower temperatures as some areas already
passing -10f in eastern yellowstone county and approaching -20f in
rosebud county. Borsum

Short term Valid for Tue and wed...

clear skies and arctic air mass in place will allow temperatures
to plummet after dark over the central and eastern plains. Temps
as low as 20 below zero by tomorrow morning with wind chills 15 to
35 below zero. Breezy southwest winds through the livingston gap
and western foothills could cause some patchy blowing snow
tomorrow until temperatures can warm above freezing. Ridging
shifting eastward will warm temperatures into 30s and low 40s for
highs Tuesday and Wednesday.

Looking at a possible wind advisory for the livingston area
Wednesday night into Thursday as low pressure system moves into
central canada and gradient tightens. Blowing snow potential is a
little unknown because temperatures will be warm enough to crust
the top layer of snow, but winds gusts 40 to 50 mph look likely.

Next chance for precip and cooler temperatures starts Thursday as
a low pressure system moves into the area. Walsh

Long term Valid for thu... Fri... Sat... Sun... Mon...

gfs and ECMWF a bite more in line this afternoon with the
evolution of a pacific trough that moves into the area Thursday
into Friday.

Front moves into the area Thursday night into Friday morning.

Rain snow line is quite messy as warm nose aloft will promote rain
and perhaps freezing rain sleet over the eastern plains. For that
reason a little hard to discern snow accumulations as initial
burst of precip could be mainly rain, with temperatures in the
upper 30s. Along the front, models show some decent instability so
some pockets of convective snow is possible. Front is a quick
hitter and accumulations generally look to be 2 to 4 inches for
this event, but is still very early and models are continuing to
adjust.

Pacific low becomes an open trough as it crosses the rockies on
Saturday. Cyclonic flow and another low pressure system shifts
into the west coast to begin next week which will trend
temperatures back down and at least keep a slight chance of snow
in the forecast. Walsh

Aviation
Ifr CIGS persisted across western areas late this evening. Expect
clouds to gradually clear overnight. Localized valley ground fog
is possible overnight as well, with CIGS and vsbys down to lifr at
times. Winds are expected to turn southwesterly along the western
foothills by Tuesday morning, with perhaps a period of patchy
blowing snow, including at klvm.VFR conditions are expected
elsewhere through the period. Stp

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
