Update
Models have had a hard time solving shallow light snow across the
eastern half of the cwa. Appears weak trowal, weak upslope and
convergence keeping it going. We are finally seeing the light snow
diminish to just flurries in the billings area, and this trend
should trend eastward overnight.

Overnight forecast of lows may be a little pessimistic given the
expectation of persistent cloud cover. So we adjusted those in a
few locations a bit. One way or the other, its still just going to
be a cold night. Bt

Short term Valid for Mon and tue...

as the snow continues to diminish across the area, the concern
turns to the low temperatures for the next couple days. The trough
continues to dig deeper in the area allowing temps to drop into
the teens below zero west of a line from forsyth to broadus on
Sunday night. East of that line, temperatures will be in the
single digits below zero. Winds will be calm during this time
leading to the decision of not issuing a wind chill advisory for
most of the cwa. Judith gap is the only location under a wind
chill advisory for tonight as winds will be slightly higher than
the rest of the cwa.

The cold temps are going to continue into Monday with high
temperatures reaching the low single digits above zero. A
vorticity low will move into the west Monday and Monday night
bringing the next chance of snow to the beartooth mountains. Low
temperatures Monday night will drop to the teens below zero for
much of the area.

Temperatures will trend back to the 20's (20 degrees below normal
for this time of year) on Tuesday as a ridge begins to build back
into the area. The area will remain dry on Tuesday with low
temperatures Tuesday night reaching the single digits above zero.

Long term Valid for wed... Thu... Fri... Sat... Sun...

models are in good agreement today for mid week into early next
weekend. Split flow aloft will be over the forecast area
Wednesday. This will bring dry conditions with the exception of
some mountain snow showers. Another upper low and trough move off
the pacific northwest coast southward through california Wednesday
night into Thursday and across the four corners region and
southern rockies Friday. The bulk of the energy and precipitation
with this low looks to remain well south of montana but the
northern fridge may bring a chance for snow Thursday into Thursday
night to our forecast area. The next chance for better snow
accumulations looks to be next weekend as both models bring a
stronger trough across the forecast area late Saturday into
Sunday, but out this far, there is plenty of time for specifics to
change. Temperatures through the period will remain below normal
with teens and 20s common. Hooley

Aviation
Light snow will gradually decrease over the area through the
evening, lingering longest over far southeast montana. MVFR to ifr
conditions are possible with the snow.VFR conditions are expected
to prevail elsewhere, with decreasing mountain obscurations
through the period. Stp

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.
