Short term Valid for tdy and sun...

the main impact in the short term remains the strong winds around
livingston. Winds are just finally starting to increase around
livingston now, however big timber has been gusting most of the
night. Today winds should stay at or below 50 mph, but it still
looks like the gradient will increase by early Sunday morning.

This still looks like a much better setup that the current setup.

It continues to look like a wind advisory will be needed.

Additionally with the strong winds, there are already some reduce
visibility around big timber. Have continued to have the blowing
snow in the forecast.

For the rest of the area, things will generally remain quiet even
with energy moving across the area. Another pacific northwest
trough will dig into the southwest. This will keep the mountains
and adjacent foothills in some snow showers, but elsewhere things
should remain dry. With the increasing downslope flow, should see
temperatures warm up a little more, with highs across the central
and western zones getting to near freezing for highs today and
above freezing for Sunday. Reimer

Long term Valid for mon... Tue... Wed... Thu... Fri...

slow moving filling trough moving across the area on Monday looks
to be fairly dry which will be followed by period of zonal flow or
shortwave ridging Tuesday and Wednesday. Ridging becomes a bit
more amplified by Thursday before shifting east on Friday in
response to a much stronger upper low along the pacnw coast.

Models prog southwesterly flow aloft heading into the weekend with
the low filling and passing through the region on Sunday. I
mainly dry weather early in the week with the exception of some
shower activity associated with a weak front passing through on
Monday. Increasing downslope flow on Wednesday does improving
mixing and try to increase temperatures but there will be a
struggle to achieve near normal temperatures given the presence of
so much cold snow. Another weak front passes through Wednesday
evening with a dry day on Thursday with a period of ridging. Given
lighter winds on Thursday thought about lowering temperatures a
bit but some erosion of snow cover may be occuring by then.

Friday into the weekend southwesterly flow aloft with ejecting
energy could start increasing precipitation chances but models are
showing the system disorganized as it finally ejects across the
area. Model solutions are not real confident at this time so do
not see a significant impact event but could be the next round of
moisture for the lower elevations. Borsum

Aviation
Downslope pressure gradient in place this morning will weaken by
this evening. This will support strong gap flow winds until later
this afternoon and generate areas of blowing snow along the
foothills. Shower activity over the mountains will produce
occasional obscurations otherwiseVFR conditions for all terminal
sites. Borsum

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
