AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
925 AM PDT WED SEP 2 2009

.SYNOPSIS...
A DEEP TROUGH OF LOW PRESSURE WILL REMAIN OFF THE COAST TODAY WITH
DRY AND WARM AIR REMAINING OVER THE REGION. THE TROUGH WILL BEGIN
TO SHIFT INLAND TONIGHT AND CONTINUE DRIFTING INLAND THROUGH THE
UPCOMING WEEKEND. THIS WILL RESULT IN A SIGNIFICANT COOLING TREND
WITH INCREASING CHANCES FOR PRECIPITATION. BY THE END OF THE UPCOMING
HOLIDAY WEEKEND TEMPERATURES WILL FALL WELL BELOW SEASONAL NORMALS
WITH SNOW EVEN POSSIBLE OVER THE HIGHEST MOUNTAINS IN THE CASCADES.

&&

.DISCUSSION...
REST OF TODAY...SATELLITE INDICATES A DEEP UPPER LEVEL TROUGH OFF
THE PACIFIC COAST THIS MORNING WITH THE FORECAST AREA REMAINING
UNDER PRE-TROUGH SOUTHERLY FLOW. SURFACE ANALYSIS INDICATES A
SURFACE THERMAL TROUGH OVER THE COLUMBIA BASIN. A WEAK UPPER
LEVEL; DISTURBANCE TRACKING UP FROM THE SOUTH CURRENTLY OVER OREGON
APPEARS TO BE MAINLY HIGH LEVEL CIRRUS WITH NEITHER NAM OR THE
LATEST GFS SUGGESTING THIS WAVE HAS ANY DEEP DYNAMIC SUPPORT AS IT
MOVES INTO THE REGION THIS AFTERNOON...WITH MODEL SOUNDINGS
SUGGESTING TOO MUCH CIN IN THE MIXED LAYER TO ALLOW ANY CONVECTIVE
DEVELOPMENT TODAY. THUS...ANOTHER QUIET AND DRY DAY WITH MAINLY LIGHT
WINDS...ALTHOUGH SOUNDINGS SUGGEST SOME MIXING GUST POTENTIAL TO
ABOUT 15 MPH ON EXPOSED TERRAIN THIS AFTERNOON. HIGH TEMPERATURES
TODAY WILL LIKELY RESEMBLE YESTERDAY'S HIGHS.

TONIGHT THE OFFSHORE TROUGH WILL SWEEP THROUGH WITH STRONG DYNAMIC
SUPPORT AND PLENTY OF MOISTURE. INITIAL THOUGHTS ARE THAT THE
CURRENT FORECAST POPS AND THE NOCTURNAL THUNDER THREAT MAY NEED TO
BE ENHANCED SOMEWHAT. THIS ISSUE WILL BE ADDRESSED WITH THE AFTERNOON
PACKAGE. IN ANY EVENT CONFIDENCE IS HIGH FOR A BIG CHANGE FROM THE
RECENT HOT AND DRY REGIME DURING THE NEXT 24 HOURS. NO UPDATE TO
STATE FORECAST PRODUCT. MINOR UPDATE TO ZONE FORECAST IMMINENT FOR
THE TODAY PERIOD ONLY. /FUGAZZI

&&

.AVIATION...
MOSTLY CLEAR SKIES AND VFR CONDITIONS EXPECTED AT ALL TAF SITES AND
THROUGH OUT THE REGION TODAY. AFTER 02Z OVER THE CASCADES SCATTERED
SHOWERS AND ISOLTATED THUNDERSTORMS WILL DEVELOP AS A STRONG
UPPERLEVEL DISTURBANCE MOVES INTO THE REGION. TONIGHT NUMEROUS
SHOWERS AND SCATTERED THUNDERSTORMS WILL OVERSPREAD THE REGION FROM
SOUTHWEST TO NORTHEAST...ENCOMPASSING THE AREA NORTH OF INTERSTATE
90 BY 08Z AND CONTINUING THROUGH 18Z THURSDAY. HOWEVER...OUTSIDE OF
THUNDERSTORM CORES CONDITIONS WILL REMAIN VFR AT ALL TAF SITES.
