Synopsis
Cold and generally dry conditions will persist through Friday
morning except for some passing light snow showers or flurries at
times. A series of storm systems will impact the inland northwest
this weekend into early next week with the potential for more
snow, breezy conditions and continued below normal temperatures for
most locations.

Discussion
No big changes anticipated for today. Low pressure will sit over
the region with the center of the upper level low centered over
the upper columbia basin. Although not a lot of moisture is
wrapping in around the low, it is enough to produce intermittent
flurries for portions of the id panhandle and extreme eastern wa.

Essentially where we see low level clouds there will be the
potential for some snow flakes to fall out. Upslope northwest flow
will increase into the camas prairie today into tonight. This will
be the are for the best potential of snow accumulations around an
inch possible. The snow will be light and dry and will unlikely
cause much in the way of travel impacts. Svh

Aviation
18z tafs: low pressure will reside over the region today with
enough low level moisture to produce intermittent flurries. MVFR
cigs vis will be possible through the afternoon at kgeg, ksff,
kcoe, kpuw and klws. Drier air moving in from the north will
result in clearing through the night. However, this clearing will
also set up the potential for strong radiational cooling with
patchy fog developing across the northern mountain valleys by
Friday morning. Confidence is low that fog will develop at the taf
sites, but the kgeg, ksff and kcoe will be threatened by it with
ifr and isolated vlifr conditions possible. Svh

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
