Area Forecast Discussion
National Weather Service Spokane WA
1047 PM PDT Wed May 31 2017

.SYNOPSIS...
A return to more seasonal temperatures for the remainder of the
week and into the weekend will allow the rivers in central
Washington to slowly recede. Scattered showers will be possible
through Friday. High pressure is expected to bring a warm and dry
day on Saturday. Cooler and showery weather will return Sunday and
Monday.

&&

.DISCUSSION...
Forecast update for this evening to modify thunderstorm chances a
bit and show a better progression of the mid level front. The
front will slowly push east through the night with clouds clearing
in the lee of the northern Cascades to the western basin. It will
become hung up over the Panhandle overnight though with clouds
and showers remaining from extreme eastern WA into the ID
Panhandle. All the cloud cover over the region is really limiting
our convective potential. Best chances for thunderstorms this
evening will be over the Pasayten Wilderness area in the far
northern WA Cascades to Okanogan Highlands and in the southern to
central ID Panhandle. I removed thunderstorms for the rest of the
region. Stronger thunderstorms with gusty outflow winds and hail
will likely remain southeast of the region. /SVH

&&

.AVIATION...
06Z TAFS: A fairly stationary frontal band will remain over the
region through tonight. Showers will continue ahead of this front
across southeast WA and into the ID Panhandle, which will include
the KSFF, KCOE, KPUW and KLWS TAF sites. Some low stratus will be
possible across these areas as well by Thursday morning with MVFR
cigs possible, but confidence is low. An upper level shortwave
disturbance will move through Thursday afternoon. Surface based
convection is expected to fire off ahead of this wave across much
of eastern WA and into the ID Panhandle. Stronger cells will be
capable of developing into thunderstorms, but tough to say if any
thunderstorms will impact the TAF sites. /SVH
