Discussion Short wave trough to our north will briefly increase
clouds in idaho this afternoon evening as it slides by in montana
and wyoming. The trough will also shift the main upper ridge over
our area to the west, but the ridge will come back in Thursday.

Warming will continue through Thursday in oregon and through Friday
in idaho with warmest-day highs reaching the 70s to mid 80s.

Upper low off oregon is forecast to come inland Friday and
directly through our CWA Saturday and Sunday. Greatest instability
for thunderstorms will occur Friday evening, and SPC targets our
cwa for greatest convective potential at that time. Current
forecast has only a slight chance of thunderstorms. That will
be increased in the afternoon package after all the 12z guidance
is in. Current forecast is on track through mid-day Friday, so no
updates at this time.

Aviation Vfr with clear skies. Surface winds, variable 10-15 kts.

Winds aloft near 10 kft msl: NW 10-20 kts.

Prev discussion
Short term... Today through Saturday... A ridge aloft will dominate
through early Friday, with dry and warming conditions.

Afternoon temperatures on Thursday and Friday should be about 15
degrees above normal. A closed pacific low drifts into the area
late Friday, bringing a chance of showers and thunderstorms late
Friday over oregon, and spreading into idaho Friday night. The low
is very slow moving, so showers and thunderstorms will continue
through Saturday. Temperatures drop back to near normal by
Saturday afternoon.

Long term... Saturday night through Wednesday... Moist unstable
air in the upper level trough will continue to support scattered
showers and isolated afternoon and early evening thunderstorms
through Monday. The trough will begin a slow exit on Tuesday,
resulting in decreasing clouds and showers. Highs will average 5
to 10 degrees below normal through Tuesday, but lows will be near
normal. Models disagree on timing the trough's departure, but by
Wednesday they do agree on building an upper level ridge over the
area, bringing mostly clear skies and a return to near normal
temperatures.

Id... None.

Or... None.

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

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.
