Synopsis
Showers and a few thunderstorms will linger over the inland
northwest today before becoming limited to mainly the
mountains on memorial day. Windy conditions are also expected
Sunday over portions of north idaho. Next week the region will
warm up to above normal. Afternoon showers and possible thunder
over the idaho panhandle and northern mountains. The rest of the
region will remain fairly dry.

Discussion
Tonight through Monday: the weather pattern across the western us is
dominated by a closed upper low currently situated over central
california. A secondary circulation is rotating counter-clockwise
around this parent low, and was the source of a quick round of
precipitation last night and this morning. Partial clearing behind
this wave has allowed for some destabilization of the
atmosphere... Some model analysis are showing over 1000 j kg of
cape. As such, showers and a few thunderstorms have formed along
an e-w oriented boundary this afternoon, running from moses lake
east toward the camas prairie. Additional convection will be
possible through this afternoon, mainly south and east of the
interstate 90 corridor. The primary threats will be brief heavy
rain that could cause localized urban flooding, along with small
hail.

Breezy north to northeast winds will diminish this evening and
tonight. The strongest winds will remain to be across northern idaho
in the corridor between sandpoint and coeur d'alene, where gusts up
to 40 mph will be possible through the afternoon.

The next chance of thunderstorms will arrive Monday afternoon, as
another easterly wave rotates through the region. The best chances
for precipitation will be across SE washington and north idaho,
including the pullman and lewiston areas. The east slopes of the
cascades may also see a few showers and thunderstorms.

Dang
Tuesday and Wednesday: a weak high pressure ridge is expected to
build in along the pacific coast and lead to a warming and drying
trend for Tuesday. Warm temperatures and lingering moisture have the
models hinting at possible afternoon convection mainly in the idaho
panhandle and cascades. Temperatures for the work week will be the
warmest of the year so far and nearing 5 to 10 degrees above the
normals. The columbia basin can expect widespread 80s. The higher
terrains will be be in the 70s range for the work week and weekend.

Wednesday night and Thursday: on late Wednesday, the ridge begins to
break down and models are indicating a dry weak low will move across
oregon. There is not a lot of moisture is associated with this low.

Models are keeping the idaho panhandle and northern mountains as the
likely areas to receive precip.

Friday and weekend: a split flow sets up in the region on Friday.

This leads to another dry period for eastern washington. Some wrap
around moisture from the low to the south continues to bring some
chances of precip to the idaho panhandle through the Saturday. By
midday Sunday, a low pressure will begin to press into the pacific
northwest. Models are not in good agreement on how this will impact
the region but winds are expected to be breezy. Jdc

Aviation
00z tafs: sct showers continue to impact puw-lws-mwh for the next
few hours. The lightning is remaining to the south of these
locations, so have left it out. Skies will remain bkn through the
night and showers and isolated thunderstorms are expected to
redevelop Monday. The best area for -shra -tsra Monday will be
around puw-lws. Confidence isn't high right now, as there are some
discrepancies in the models. Have -shra for lws, but have left
out thunder attm.

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.
