Synopsis
Warm daytime highs are expected through Thursday, with mostly
clear skies. A cold front moving on the region Thursday night into
Friday will bring cooler, windy and mainly mountain showers to
the region for the weekend and into early next week.

Discussion
Today through Wednesday night: dry forecast with seasonal
temperatures is expected as a ridge remains off the west coast.

With northwest flow aloft we will see some high clouds move
through from time to time, otherwise clear skies is anticipated.

Winds will remain light. Some patchy morning fog is possible for
the valleys of N id and NE wa this morning. Temperatures will
continue to warm each day. By Wednesday we will see temperatures
3-6 degrees above average for this time of the year, or valley
temps in the 70s. Enjoy it, fall is here! Nisbet
Thursday through Friday: an upper level jet draped over bc and
into NW montana will push a dry cold front through the region this
period. The major impact is expected to be gusty winds down the
okanogan valley and the columbia basin. An isolated mountain snow
or rain shower for the higher elevations is possible but the bulk
of the moisture will be over montana.

Saturday through Monday: by late Saturday, the models are
indicating a low will push into the pacific northwest in southern
oregon. This low will carry band of moisture that will spread
across the region north of i-90, from west to east, by late
Sunday. The models poor agreement keeps confidence of precip
chances for the columbia basin low. Mountain showers have a
better confidence.

The cold front will bring a decline to the temperatures. Highs in
the 70s on Thursday will dip into 60s for Friday and Saturday.

Increasing clouds will help keep the region from radiating at
night. Lows for the region will be in the 40s. Jdc

Aviation
12z tafs: the region will be under dry northwest flow with a few
high cirrus filtering in at times.VFR conditions expected at all
taf sites. Patchy fog is expected in the mountain valleys of
northeast wa and in the id panhandle early this morning.

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.
