NATIONAL WEATHER SERVICE SPOKANE WA
1021 PM PST MON NOV 23 2009
SYNOPSIS
WEAK PACIFIC WARM FRONT WILL BRING A POSSIBILITY OF VERY LIGHT
PRECIPITATION TONIGHT...WITH GENERALLY DRY BUT CLOUDY WEATHER
RETURNING TUESDAY AND THROUGH THANKSGIVING DAY. ON FRIDAY A COLD
FRONT WILL PASS THROUGH WITH ANOTHER REASONABLE CHANCE OF MOUNTAIN
SNOW AND VALLEY RAIN OR SNOW. CONDITIONS WILL REMAIN CLOUDY AND
UNSETTLED INTO NEXT WEEKEND.
DISCUSSION
FORECAST FOR TONIGHT IS ON TRACK WITH WARM FRONT NOW BEGINNING TO
MOVE ACROSS CENTRAL AND NORTHERN WASHINGTON. ONLY CHANGE WAS TO
RAISE LOW TEMPERATURES FOR THE OKANOGAN VALLEY...WENATCHEE
AREA...MOSES LAKE AREA...COLUMBIA BASIN...AND LEWISTON AREA. THIS
IS DUE TO CLOUD COVER WITH THE INCOMING FRONT KEEPING TEMPERATURES
NEARLY STEADY THROUGH THE NIGHT. THIS IS TRUE FOR MOST OF THE
AFOREMENTIONED AREAS EXCEPT LEWISTON. HERE THERE MAY BE A BRIEF
BREAK IN CLOUD COVER THIS EVENING WITH SKIES BEGINNING TO CLEAR
OUT NOW...BUT A PERSISTENT SOUTHEAST WIND OF 5 TO 15 MPH SHOULD
HELP LIMIT RADIATIONAL COOLING POTENTIAL. JW
AVIATION
A WEAK WARM FRONT WILL TRACK THROUGH EASTERN WASHINGTON AND NORTH
IDAHO TONIGHT. MOISTURE IS LIMITED WITH THE FRONT SO MAINLY SCT
-SHRA/-SHSN EXPECTED AT THE TAF SITES. CEILINGS WILL LOWER AS THE
FRONT MOVES THROUGH WITH A CHANCE OF MVFR CIGS AT KGEG/KSFF/KCOE
AFTER 11Z. MODEL DATA INDICATES NEARLY SATURATED LAYER TOMORROW
BETWEEN 5000-10000 FT MSL AS ANOTHER WARM FRONT APPROACHES...SO
WIDESPREAD VFR CIGS ARE EXPECTED OVER THE VALLEYS WITH AREAS OF MVFR
CIGS POSSIBLE. JW
