Synopsis
Weak low pressure will remain over the inland NW overnight into
Thursday with isolated showers and a few thunderstorms near the
canadian border. A wetter storm system will bring increasing rain
chances Friday night into Saturday. The weather remains cool
through the weekend with a chance for at least mountain showers
into Sunday. Dry and milder weather is possible for next week.

Discussion
Made a few updates to the forecast based on current trends. Radar
shows light showers moving from the northern cascades, across the
okanogan valley into the okanogan highlands. This meshes well with
the meso scale models. There were some cloud flashes early this
evening, but no lightning. Brief downpours from a stronger cell
did give twisp 0.04". The convection looks to weaken slightly, but
may slowly track eastward this evening with the upper level
shortwave. Convection flared up in western mt, but not some
distance southeast of mullan pass. Aside from the mid level clouds
from the light showers, expect mostly clear to partly cloudy
skies. Rfox.

Aviation
06z tafs: a weak disturbance will push across northeast washington
and north idaho with mid to high level clouds, but the TAF sites
should remain mostly clear. Clouds will increase by morning with
bases gradually lowering Thursday afternoon and evening with the
incoming northwest flow and moisture band. Precipitation will be
held to the northern mountains. All TAF sites should remainVFR
through the period. Except for the downslope winds at keat
overnight, winds should remain light southerly. Still looks like
southwest to west winds pick up Thursday afternoon and evening
near 12 kts at kgeg and kpuw with some afternoon gusts. Rfox.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
