AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
655 AM PDT Thu May 23 2013

.SYNOPSIS...
Cool, showery weather will continue over the Inland Northwest due
to a lingering upper low. Snow will also be possible over the
mountains. Conditions could moderate a bit by the weekend, as the
low moves out of the area, but it will be replaced by another cool
low sometime early next week.

.DISCUSSION...
Update:quick update to remove the freezing warning from the
Palouse, central Panhandle and parts of Nez Perce and Lewis
county. Temperatures are warming up. Also made minor adjustment to
cloud cover. Fog from earlier this morning is also beginning to
wane some but some stratus is holding on in some of the northeast
valleys through the central Panhandle. /J. Cote'

.AVIATION...
12Z TAFS: Low level moisture will promote areas of low clouds and
patchy fog this morning around north TAF sites...especially the
KGEG-KCOE corridor. At the same time an unstable upper low
remains in the region. This unusual set-up degrades confidence in
the persistence and timing of low clouds and fog. However expect
IFR conditions through 15-17Z, before mixing mixing and increased
instability with the nearby low helps lift the clouds. The
afternoon will bring an increased threat of rain showers and
perhaps some thunderstorms. The overall best threat will remain
closer to Cascades, near the center of the low, i.e. near KEAT.
The overall threat wanes after dark with the loss of daytime
heating, but a few showers will still remain possible near the
Cascades and Blue Mountains. /J. Cote'
