AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
1055 PM PDT SAT MAY 18 2013
SYNOPSIS
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WILL DEVELOP AGAIN
THIS AFTERNOON AND EVENING. THE GREATEST THREAT OF THUNDER WILL
OCCUR OVER THE NORTHEAST CORNER OF WASHINGTON AND MUCH OF THE
IDAHO PANHANDLE. PRECIPITATION CHANCES WILL DIMINISH A BIT ON
SUNDAY AND BY MONDAY MOST LOCATIONS WILL BE DRY. THIS DRYING WILL
COME TO AN ABRUPT END BY TUESDAY AFTERNOON AND INTO WEDNESDAY AS A
A VERY COOL AND WET UPPER LEVEL LOW PARKS ITSELF OVER THE INLAND
NORTHWEST. STEADY, MODERATE PRECIPITATION WILL BE POSSIBLE
ESPECIALLY OVER NORTHEAST WASHINGTON AND THE NORTHERN PANHANDLE.
DISCUSSION
A QUICK UPDATE LATE THIS EVENING TO ADD SOME PATCHY FOG TO THE
FORECAST IN THE NORTHERN MOUNTAIN VALLEYS AND DOWN THE OKANOGAN
VALLEY. RADAR ESTIMATES INDICATE A QUARTER TO A HALF AN OF
RAINFALL ACROSS SOME OF THESE VALLEY THROUGH THIS EVENING. DEW
POINT DEPRESSIONS ARE CLOSE TO ZERO. OBSERVATIONS AT OMAK RECORDED
OVER THREE-TENTHS OF AN INCH OF RAINFALL THIS EVENING AS A SHOWER
PERSISTED OVER THIS AREA THROUGH MUCH OF THE EVENING. THUS, THE
BOUNDARY LAYER WILL BE MOIST ENOUGH AND WE SHOULD SEE ENOUGH
COOLING THROUGH THE NIGHT FOR SOME FOG THROUGH EARLY TOMORROW
MORNING ACROSS THESE VALLEY LOCATIONS EVEN WITH THE MID LEVEL
CLOUD COVER. /SVH
AVIATION
06Z TAFS: MOSTLY CLOUD SKIES ARE EXPECTED OVER THE REGION THROUGH
TONIGHT WITH SHOWERS REMAINING CONFINED MAINLY ACROSS THE NORTHERN
MOUNTAINS. SOME STRATUS MAY BEGIN TO DEVELOP IN THE SPOKANE/COEUR
D'ALENE AREAS TONIGHT AS THE BOUNDARY LAYER REMAINS MOIST, BUT
CONFIDENCE IS LOW AS THICK MID LEVEL CLOUD COVER MAY NOT RESULT IN
ENOUGH COOLING TONIGHT LOWER IN THE ATMOSPHERE FOR STRATUS
DEVELOPMENT. MOUNTAIN SHOWERS ARE EXPECTED TO DEVELOP THROUGH
SUNDAY AFTERNOON, WHICH MAY PUSH SOUTH OFF THE NORTHERN MOUNTAINS
INTO KGEG, KSFF AND KCOE WITH -RA POSSIBLE. /SVH
