Discussion The forecast of low clouds (stratus), freezing fog
(producing rime ice or hoarfrost), and below normal temperatures
will remain common this week throughout many valleys across
central idaho and western montana. Some snow flurries or ice
crystal deposition may occasionally precipitate from the stratus,
but only amount to at most a light dusting of white. An alberta
clipper will skip across eastern montana and north dakota, leaving
some mid level moisture strewn across the idaho panhandle and
western montana Tuesday night into Wednesday. This could help
improve conditions where freezing fog exists, lifting the fog into
a stratus deck. The additional mid level mountain top moisture
could produce more widespread light snow flurries. But still only
a skiff of snow seems most likely.

High pressure rebuilds over the area on Thursday with inversions
strengthening yet again. However models still indicate a pattern
change is on the way starting sometime Friday when a cold front
quickly sweeps through the northern rockies. There could be some
potential for freezing drizzle at the onset of precipitation. But
light snow seems most likely given the lack of warming aloft ahead
of the cold front. But we'll keep evaluating this part of the
forecast as model confidence builds in the coming days. The rest
of the weekend continuing into next week still appears to be
fairly active as a series of weak weather features are forecast to
pass through the flow. But models are still not very consistent
with their placement of the upper level jet stream and larger
scale upper level pattern over the pacific ocean. And thus, while
a pattern change is certainly welcome, no big storm systems seem
likely at this time through the middle of next week.

Aviation Strong valley inversions will remain the next several
days with abundant stratus and areas of freezing fog. Kgpi, kmso
and ksmn will experience low ceilings from stratus with the lowest
ceilings during the morning hours. Freezing fog is possible
mainly at kmso during the overnight and morning periods.

Occasional snow flurries will also be possible, especially around
kmso with only trace amounts expected.

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.
