AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
1055 AM PDT Sat Aug 3 2013

.SYNOPSIS...
Unsettled weather will continue today with rain showers and the
possibility of a few thunderstorms before tapering off in the
evening hours. Summer-like weather will return next week with a warm up
back to normal and eventually above normal temperatures by the
middle of the week. A small chance of mainly mountain thunderstorms
will be present almost each day throughout the week.

.DISCUSSION...
We continue to be under a stretched out deformation band of clouds
from Portland to Kalispell. This band is producing occasional
areas of light rain showers. This morning's showers are fading at
the moment over the Basin and Palouse. A new area of showers is
developing over NW Montana and will move into the northern
Panhandle later this morning. 

All of this cloudiness will inhibit warming today so the threat of
thunderstorms is very small. This is not the case over the
Cascades and Okanogan Highlands where sunshine will allow the
mountains to warm quickly. This coupled with the abundant moisture
in place will rapidly destabilize the atmosphere leading to heavy
rain showers and thunderstorms this afternoon and evening. Not
anticipating the need for any kind of flash flood watch but will
continue to monitor. For the past 2 days we've had isolated
thunderstorms put down copious rainfall and today could be the
same.  

Other change to the forecast was to cool afternoon temperatures a
few degrees. This may need to be revised further based on the
cloud cover.  RJ

.AVIATION...
18Z TAFS...A very moist atmosphere remains in place over the area 
today.  Mountain showers and thunderstorms will develop over the 
Cascades and northern Mountains.  None of this activity is expected 
at the TAF sites.  VFR weather is expected with a BKN cloud layer 
today and this evening.  There is a slim chance of some fog 
formation tonight, but this was left out of the TAFs for now.  RJ
