Short term Tonight through Wednesday... Periods of light
snowfall will continue generally east of boise this evening as
the weak band of snowfall moves east across the area. Drying
conditions noted overnight. Expect fog to cover much of the area
Tuesday morning, which may impact travel. Fog cover should lift
during the late morning hours. Meanwhile, the next active system
will move into eastern oregon Tuesday afternoon. Snowfall will be
present across the higher terrain of baker county by Tuesday
afternoon. Snowfall associated with this moisture system will move
into the central idaho mountains quickly, with periods of moderate
mountain snow possible through Wednesday morning. Travel impacts
will be felt and a winter weather advisory is in effect for the
higher terrain of baker county and much of the west central and
boise mountains, and the upper weiser river of idaho. Snowfall
should improve through Wednesday afternoon, though light snowfall
may remain present. The lower elevations are expected to see more
of a wintry mix as this system moves through. Variations in the
rain snow line exist between the models, which will influence the
amount of impact felt by this system. Threats to the lower
elevations will continue to be monitored. Gusty winds will also be
found across the area under the influence of this approaching
system, especially across southeastern oregon, and the owyhee
mountains and southwest highlands of idaho. Otherwise,
temperatures will generally be right around normal for Tuesday,
and warming to slightly above normal for Wednesday.

Long term Wednesday night through Monday... The trough passage on
Wednesday will make Thursday morning quite chilly with morning lows
in the teens to low 20's. A weak ridge builds over the area for
Thursday afternoon and evening before another system drops in from
the west. Higher elevations will see the highest pops with this
first system Friday night into Saturday. Another ridge builds
overhead for Saturday evening into Sunday. The ECMWF wants to split
Sundays system and drop most of the precipitation to our south. The
gfs on the other hand, still wants to bring in much higher qpf
amount, mostly in the higher elevations. Some variations in snow
levels among the models means lower valleys could see a wintry mix
or rain with Sundays system. A warm frontal band pushes in Monday
raising snow levels above 4k feet and bringing widespread
precipitation.

Aviation MVFR ifr within snow with mountain obscurations. Snow
will continue pressing southeastward through SW idaho this afternoon
exiting ktwf kjer area after 05z. Fog stratus will develop early
morning causing widespread MVFR ifr conditions. Surface winds,
variable 5-10kts. Winds aloft to 10k feet msl, northwest-west 15-
20kts through early Tuesday then westerly 20-25kts.

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.
