Area forecast discussion, Sep 5, 8:30 PM PDT, 12 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
830 PM PDT Thu Sep 5 2013
.SYNOPSIS...
The next few days will be stormy with the potential for heavy
rain and thunderstorms. This evening and overnight, there will be
the threat for damaging thunderstorm winds and hail. Flash
flooding will be a concern tonight, and Friday. The slow moving
low pressure system responsible for the stormy weather will begin
to move out of the region on Sunday. Monday through Thursday
should be warm and will allow the Inland Northwest to dry out.
&&
.DISCUSSION...
...STRONG THUNDERSTORMS WILL CONTINUE TONIGHT...
Evening update to remove our southeast counties from Severe
Thunderstorm Watch 511, which expired at 8 pm. Garfield and Asotin
Counties in WA as well as Lewis and Nez Perce Counties in ID are
no longer under the threat of damaging thunderstorms. Showers and
weaker thunderstorms will continue during the evening and into the
overnight hours across the southeast zones, but damaging winds are
no longer expected. Severe Thunderstorm Watch 513 remains in
effect tonight for the remainder of eastern WA and north ID. A
strong gust front will move north across eastern WA this evening
with damaging winds possible. The main threat now appears to be
flash flooding from extremely heavy rain. Strong thunderstorm
cells will continue to affect some of the recent burn scars that
are vulnerable to flash flooding and debris flows. /Kelch
&&
.AVIATION...
00Z TAFS: Very moist and unstable airmass and disturbances rotating
through it have brought significant thunderstorm activity to Eastern
Oregon this afternoon and this will all track to the north and into
Eastern Washington and Northern Idaho this evening and through the
night. In addition to a significant amount of lightning from
thunderstorms they will also bring the potential for very strong and
damaging wind and large hail. The majority if not all of the severe
storm activity should decrease after 8Z Friday. Otherwise VFR
conditions should prevail with exception of localized MVFR ceilings
and visibilities near thunderstorms any any morning stratus/fog that
may form due to the leftover rainfall keeping an abundant source of
moisture at low levels. /Pelatti
