Synopsis
High pressure builds over the region this weekend. A few showers
and isolated thunderstorms are possible around the idaho panhandle
this afternoon and evening. Limited thunderstorm chances develop
around the cascades, and perhaps the canadian border, each
afternoon between Sunday and Tuesday. Otherwise expect dry, warm
weather into early next week, with afternoon highs in the 80s.

This mild weather will contribute to rises on rivers in central
and north central washington. A threat of unsettled weather
returns in the middle to late next week, with slightly cooler
temperatures.

Discussion
Tonight and tomorrow: the northerly flow allowing weak disturbances
to fire off very light and spotty convection over portions of north
idaho this afternoon and early evening gets shunted to the east
tonight as an upper level ridge of high pressure amplifies over
eastern washington and north idaho while the ridge axis migrates
from near the coast today to over the cascades tomorrow. This will
result in a warming and drying trend with forecast temperatures
above normal for this time of year, especially daytime highs
tomorrow. Surface winds are expected to remain fairly diurnal
upslope to upvalley during the day transitioning to downslope and
downvalley winds overnight. Pelatti
Sunday through Tuesday: the two points of interest in the extended
period are the unseasonably warm temperatures and the eventual
return of shower and thunderstorm chances to the region. On Sunday
we're squarely under a stabilizing ridge of high pressure that
will hang around through at least the memorial day weekend. This
is great news to those that are used to our typically cooler
holidays in years past. We will be clear and dry with temperatures
on the increase each day through Tuesday as the ridge axis
approaches and 850 mb temps reach near 19c. High temperatures will
be 10-15 degrees above average for late may, with highs in the
mid 80s and even the 90s in parts of the deep columbia basin. This
warming will lead to increased mountain snow melt and rises on
area river and streams over the next few days. Keep in mind that
water temperatures are still quite cold given this snowmelt.

While the ridge will be the dominating player, some scattered mountain
showers will be possible rounding the ridge each afternoon evening
beginning on Sunday and increasing in coverage each afternoon.

Flow becomes southwest on Sunday, advecting more moisture over
central wa at the mid levels. This, together with orographic lift
will be able to initiate some mountain showers. Warm temps and
increasing lapse rates will give enough instability over the
mountains for some weak thunderstorm potential as well. Coverage
increases over the mountains on Monday afternoon and even more so
late Tuesday.

Tuesday night through Friday: models begin to diverge on exactly
when the ridge will break down. While the GFS has been the most
bullish in bringing a trough in late Tuesday Wednesday, the ec and
canadian models are beginning to come into agreement with this
earlier timing. This means we'll see a bit of a cool down and a
good chance for showers and thunderstorms on Wednesday and
Thursday as the negatively tilted trough moves through. Behind the
trough flow becomes more zonal with a few ripples in the flow
capable of bringing hit and miss showers on Friday. Bw

Aviation
00z tafs: showers and isolated thunderstorms over the southern to
central idaho panhandle will dissipate quickly this evening. A
strong ridge of high pressure will build further into the region
on Saturday. Flat cumulus will be possible over the higher terrain
Saturday afternoon; otherwise,VFR conditions and weak winds will
continue across the region through 00z Sunday. Svh

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.
