Synopsis
The weather for the weekend will be quite warm. Afternoon
temperatures on Saturday will likely reach the mid 80s to low 90s.

Sunday and Monday will be even warmer with most lowland areas
reaching the 90s. A return to cooler, more average temperatures
are expected by the middle of next week, with breezy conditions
possible late Monday through Tuesday.

Discussion
Today through Sunday night: a strong upper-level ridge will
amplify along the western us coastline over the next 48 hours
then shift inland on Sunday. The inland northwest will remain
quite dry with temperatures climbing well above average. Friday
will feature widespread 80s then by Sunday afternoon, expect most
locations to be in the 90s. A few locations in the lower columbia
basin may be reading triple digits by the end of the weekend.

Winds will be light over the next few days blowing from the
north northeast today and Saturday then swinging around to
east southeast Sunday. Sb
Monday through Tuesday night: by Monday, the main ridge axis has
shifted east but nonetheless it will be another hot day with 850
mb temps in the 23-25 c range yielding widespread upper 80s and
90s. By Monday evening, both the GFS and to somewhat a lesser
extent the ec advertise a wave riding up from the SW through SE wa
and the central idaho panhandle. The instability over this region
is mainly capped but there may be just enough forcing to get a
couple thunderstorms going during the evening and into the
overnight hours. If any storms can get going, forecast soundings
show the potential for some gusty outflow winds. Winds over the
east slopes will also be on the increase by the evening hours
Monday.

The ridge breaks down overnight Monday and into Tuesday as a
system passes by to the north dragging its associated cold front
through the region. The GFS still wants to bring the shortwave
further south clipping the northeast portions of our forecast area
while the ec keeps the low well north in canada. Because of this,
maintained a small shower thunderstorm chance across far NE wa
and the N idaho panhandle. The main weather concern for Tuesday
will be the windy and dry conditions. The gradient tightens by
Monday night and Tuesday resulting in gusty west-southwest winds.

Bufkit and 850 mb winds suggest gusts generally in the 20-35 mph
range, perhaps higher in the usual cascade gaps. Drier air will
also be filtering into the region, and while high temperatures
Tuesday will be around 10 f cooler than Monday, rhs will be in the
mid teens to mid 20s. This combination low rhs and gusty winds
after several days of hot dry weather will lead to fire weather
concerns in the Monday evening through Tuesday night time frame,
particularly for the finer fuels in the basin.

Wednesday through Friday: by Wednesday, the gradient slackens with
decreasing winds and near seasonal temperatures. From here, models
are in somewhat better agreement keeping the region in northwest
flow with the occasional passing wave. This will lead to near
seasonal temperatures and the occasional small precip chance over
the mountains of NE wa and the N id panhandle. Kalin

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.
