AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
916 PM PDT THU JUL 24 2014

.SHORT TERM...UPDATE...THE REGION WILL BE UNDER AN INCREASINGLY DRY
WESTERLY FLOW TONIGHT INTO FRIDAY. SKIES ARE GENERALLY CLEAR TO
MOSTLY CLEAR EXCEPT ALONG THE WASHINGTON CASCADE EAST SLOPES WHERE
CONDITIONS ARE PARTLY TO MOSTLY CLOUDY. SHOULD SEE THESE CLOUDS
ALONG THE WASHINGTON CASCADE EAST SLOPES GRADUALLY DECREASE
OVERNIGHT WITH CLOUDS MAINLY NEAR THE CREST BY DAYBREAK. LOCALLY
BREEZY WINDS ARE DECREASING WITH THE STRONGEST WINDS OVERNIGHT TO BE
IN PORTIONS OF THE KITTITAS VALLEY (THESE BEING 10-15 MPH BY THE
EARLY MORNING HOURS). OVERNIGHT LOWS SHOULD AGAIN BE AT OR A BIT
COOLER THAN SEASONAL DUE TO CLEAR SKIES, LIGHTENING WINDS AND A
DRIER AIR MASS. UPDATES THIS EVENING INVOLVED ADJUSTING WINDS, LOW
TEMPS AND SKY COVER. 90

.LONG TERM...PREVIOUS DISCUSSION...STRONG UPPER LEVEL RIDGE WILL
REMAIN OVER THE WESTERN THIRD OF THE COUNTRY NEXT WEEK. THIS WILL
BRING HOT WEATHER TO THE REGION. HIGHS WILL BE IN THE 90S FOR MANY
LOCATIONS WITH THE COLUMBIA BASIN GETTING NEAR 100. ASIDE FROM THE
HEAT THE MAIN CONCERN WILL BE MONSOON MOISTURE MOVING ACROSS THE
REGION AT TIMES GENERATING THUNDERSTORMS. AT THIS POINT MOISTURE IS
SOMEWHAT LIMITED AND FLOW ALOFT IS SOUTHWEST. BASED ON THIS HAVE
KEPT THE MENTION OF STORMS OVER THE HIGHER TERRAIN OF CENTRAL AND
NORTHEAST OREGON.

&&

.AVIATION...PREVIOUS DISCUSSION...00Z TAFS. SCT 050-080 THROUGH
SUNSET THEN CLEAR OVERNIGHT INTO FRIDAY. WESTERLY WINDS 10-25KT
THROUGH EVENING BECOMING LIGHT AND VARIABLE OVERNIGHT. WESTERLY
WINDS 5-15KT FRIDAY.

&&

.FIRE WX...PREVIOUS DISCUSSION...BREEZY WINDS WILL CONTINUE THROUGH
THE EVENING BEFORE DECREASING OVERNIGHT. TEMPERATURES WILL WARM AND
RELATIVE HUMIDITY WILL DECREASE THROUGH THE WEEKEND. THE NEXT
CONCERN WILL BE THE POTENTIAL FOR SOME MONSOON MOISTURE MOVING INTO
CENTRAL OREGON AS EARLY AS SUNDAY AFTERNOON/EVENING. THIS COULD LEAD
TO THE DEVELOPMENT OF A FEW THUNDERSTORMS. MOISTURE WILL MOVE
FURTHER NORTH AND EAST ON MONDAY FOR A BETTER POTENTIAL FOR
THUNDERSTORMS OVER CENTRAL AND NORTHEAST OREGON DURING THE AFTERNOON
AND EVENING.
