Synopsis
Dry weather is expected much of this week, with our warmest
weather of the spring season thus far. By Thursday and Friday,
some of our lowland areas will have a shot of reaching 80 degrees
or more. Changes are expected by the weekend, with a threat of
showers returning to the region as well as cooler temperatures.

Discussion
Today through Wednesday: high pressure steadily amplifies over
eastern washington and northern idaho allowing for a a continuation
of generally clear and sunny skies coupled with a warming trend. One
possible interruption to this weather pattern may be in the form of
a disturbance dropping down from the northwest and making a
northwest to southeast oriented passage through the forecast area
Wednesday. Current model runs suggest this disturbance passage will
cause the prevailing winds to blow more from the north northwest
with perhaps some gusty wind and a bit more middle and upper level
clouds Wednesday but the warming trend coupled with a dry
forecast should continue uninterrupted. Pelatti
Thursday-Sunday: general agreement on the fact that the region
will be affected by a slow moving low during this part of the
forecast. But the details aren't certain. The models have
struggled with this low in previous forecasts and this will
probably continue for another couple of days. Previous models
expected the low to go well south of our area, leaving us warm and
dry. But now they all agree that the low will track much closer to
us. The GFS and canadian models would fire off
showers thunderstorms Friday afternoon evening, with much wetter
weather for the weekend. The ECMWF continues to insist on a slower
and drier solution. At this point i've kept Friday dry for the
most part, bringing in a better threat of showers on Saturday and
Sunday.

The warm spell will reach it's peak on Thursday or possibly
Friday with cooler temperatures for the weekend. This will have
large implications for the snowmelt and potential river flooding.

At this point the river forecasts are all fairly well behaved as
this is only a minor "heat wave". Rj

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.

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.
