Update
Areas of fog continue to persist across the livingston area,
including the shields and paradise valleys. I have updated the
grids to reflect this in the forecast for the remainder of the
morning. Southwest winds will pick up within the next few hours
for livingston which will allow the dissipation of the fog. No
other updates were made to the forecast. Expect a partly sunny day
with cooler temperatures. Afternoon highs will range from the
upper 40s for livingston to the upper 20s out in baker. Hooley

Short term Valid for tdy and wed...

the inherited short term forecast is in fairly good shape.

Significant changes were made, however to greatly increased winds
through the bulk of the period, to support issuance of a wind
advisory for livingston and nye areas.

The cold front will retreat quickly this morning. Cold
temps to start the day, and some remnant cloud cover will keep
temps a bit cooler, with highs in expected in the 40s. Ridging
aloft builds in fairly quickly, driving temps into the 60s for
Wednesday, and a return of mainly dry conditions. Some moisture
and energy will slide up the back side of the ridge Wednesday,
bringing a chance of precip to the higher elevations.

The biggest concern for the bulk of the extended period will be
gusty winds, with especially strong winds in the along the
foothills from livingston to nye once again. Winds will start to
increase this evening with pressure gradients tightening up to
support gusts approaching 60 mph by around 00z to 03z Wednesday.

Lag guidance supports advisory strength winds by 06z to 09z
Wednesday. Surface gradients look supportive of wind gusts
exceeding 50 mph through the day Wednesday and into the extended
period. Have issued wind advisory from 21z today through 06z
Friday. Aag

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

medium range guidance in overall good agreement. Thanksgiving day
continues to look dry and windy with record or near record highs
in many areas as temperatures reach well into the 60s. Another
pacific front and strong upper level short wave move across the
region Thursday night into Friday morning bringing our next round of
rain and snow showers. Have trended precipitation chances up for
this event. Heights begin to build Friday into the weekend for overall
dry conditions returning. Yet another pacific front could then
push through next Monday with more showers. Frieders

Aviation
Vlifr to ifr conditions in fog and stratus at klvm are expected
to improve toVFR by 19z. MVFR ceilings will improve over kshr by
18z. Otherwise,VFR will prevail across the area through
Wednesday morning. Expect localized mountain obscurations over the
beartooths, absarokas and crazys this afternoon, increasing to
areas of obscuration this evening. Obscurations will continue into
wed. Morning. Localized obscurations will affect the NE bighorns
wed. Morning. SW surface winds will increase over klvm and nearby
foothills this evening to 25 to 40 kt, with gusts to 50 kt, and
continue through wed. Morning. Arthur

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.
