Synopsis
The inland northwest will experience high temperatures in the 70s
for the remainder of the work week. Some of our typically warm
lowland spots will have a shot of 80 degrees or more Thursday and
Friday. Cooler and showery weather will arrive over the weekend
and linger into early next week.

Discussion
Today through Thursday night: high pressure aloft with a lower level
thermally induced area of low pressure to the southwest near the
coast remains in place in some shape or form into Thursday night. A
minor disturbance drops down and pushes the ridge back a bit on
Wednesday but the only effect expected by this will be a slight bump
up in north northeast winds Wednesday, otherwise the general overall
trend of a dry forecast with a gradual warming trend with
temperatures on the warm side of what would be considered normal for
this time of year remains in place through this time interval.

Pelatti
Friday through Tuesday: models are coming into better agreement on
the closed low that will affect our area this weekend. The gfs
continues to be the fastest model, but it has slowed a tad from
previous runs. This means that Friday's temperatures will be
warmer than the previous forecast. Spokane may hit it's first 80f
of the season.

I stayed away from the GFS idea of bringing rain into the area
Friday night, but held off until Saturday. Temperatures will be
cooler so the threat of thunderstorms is low, with the best chance
in the southern panhandle. Sunday will be cooler still with the
best likelihood of rain. The easterly flow on the north side of
the low means that the cascades could be rather wet. This coupled
with snowmelt could cause some rivers to approach or exceed flood
stage late in the weekend or early next week.

The low is very slow to move out of the area on Monday, and mainly
mountain showers will continue on Tuesday. Rj

Aviation
12z tafs: high pressure will keep generally clear skies andVFR
conditions over the aviation area through 12z Wednesday. Pelatti

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.

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.
