Synopsis
A warming trend is expected into the weekend, peaking on Sunday,
before a dry cold front passage Sunday night allows temperatures
to dip a little. Yet overall it remains warm into next week.

Isolated afternoon and evening thunderstorms may form near the
british columbia border, as well as over extreme southeast
washington and the lower idaho panhandle, through the first part
of the next week.

Discussion
Evening update: forecast generally on track, but the upper trough
tracking across the northern tier could trigger some isolated
t-storms across the northeastern okanogan. Confidence is low, but
given laps data showing some instability in the region and
hi-resolution models indicating some potential for the next few
hours, I updated forecast to add a risk across northeast okanogan
county (mainly in the mountains and not in okanogan valley) into
north ferry and along the canadian border into northern pend
oreille county.

The other weather feature of the evening remains the winds and
these are blowing between 10-20 mph from the lee of the chelan
county cascades east into the columbia basin and spokane area and
palouse, as well as some of the l-c valley. The strongest are
being reported around places from near entiat onto the waterville
plateau, with gusts near 30 to around 40 mph. All these speeds
should decline after sunset, though they may hold on a linger
longer near lee of the east slopes of the cascades. J. Cote'

Aviation
00z tafs: a mid-level trough moves across the region, with some
middle to high clouds and breezy conditions this evening. Winds
will abate after 02-04z at most locations, but may hold on longer
near eat. Gusts around 25kts will be possible. Some patchy blowing
dust is possible over the columbia basin early this evening too.

OtherwiseVFR conditions are expected. A limited -shra -tsra
threat will be found near the cascades and canadian border, but
taf sites are expected to remain dry. Friday will be dry, with
lingering middle to high clouds and lighter winds. J. Cote'

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.
