AREA FORECAST DISCUSSION

300 AM PDT WED AUG 5 2015

.SHORT TERM...TODAY THROUGH FRIDAY...THERE ARE STILL SOME SHOWERS
AND THUNDERSTORMS OVER NORTHEAST WALLOWA COUNTY THIS MORNING...BUT
IT IS RAPIDLY MOVING TO THE NORTHEAST AND OUT OF THE CWA. THERE ARE
ALSO SHOWERS AND THUNDERSTORMS SOUTH OF THE CWA IN SOUTHEAST
OREGON...MOVING TO THE NORTHEAST. BELIEVE THESE WILL STAY SOUTH OF
THE CWA THIS MORNING. ONE UPPER LOW WILL EXIT THE REGION THIS
MORNING AND THEN ANOTHER WILL MOVE DOWN FROM WESTERN CANADA LATER
TODAY AND TONIGHT. THIS NEXT TROUGH WILL HAVE LITTLE MOISTURE BUT IT
WILL BRING BREEZY TO WINDY CONDITIONS IN THE USUAL WINDY LOCATIONS
SUCH AS THE EASTERN COLUMBIA RIVER GORGE AND THE KITTITAS VALLEY AS
WELL AS THE BASIN AND BLUE MOUNTAIN FOOTHILLS. ALSO TEMPERATURES
WILL BE COOLER WITH HIGHER HUMIDITIES AS THIS TROUGH MOVES INTO THE
REGION. FIRE WEATHER SHIFT WILL NEED TO EVALUATE WHETHER THERE WILL
BE A NEED FOR RED FLAG WARNINGS FOR RH AND WIND. AT THIS TIME IT
LOOKS LIKE HUMIDITIES WILL BE HIGH ENOUGH SUCH THAT A RED FLAG
WARNING WILL NOT BE NEEDED. THE FLOW WILL BECOME WESTERLY ON
THURSDAY AND FRIDAY WITH DRY CONDITIONS AND LOCALLY BREEZY IN THE
AFTERNOONS AND EARLY EVENINGS...ALONG WITH COOLER TEMPERATURES. SOME
INSTABILITY AND MOISTURE WILL CREEP NORTHWARD FROM THE SOUTHWEST
INTO SOUTHERN OREGON ON FRIDAY AFTERNOON. AT THIS TIME THIS MOISTURE
AND INSTABILITY WILL STAY FAR ENOUGH TO THE SOUTH THAT IT WILL NOT
AFFECT THE CWA...BUT IT WILL NEED TO BE MONITORED. 88

.LONG TERM...FRIDAY NIGHT THROUGH TUESDAY...FRIDAY NIGHT AN UPPER
LOW MOVES SOUTH ALONG THE BRITISH COLUMBIA COAST AND A WEAK WAVE IN
NORTHERN CALIFORNIA. THIS WILL GIVE US A SOUTHWEST FLOW OF MOISTURE
INTO CENTRAL OREGON AND A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS
FROM CENTRAL OREGON SOUTH OF MADRAS AND IN THE EASTERN MOUNTAINS
THAT WILL TAPER OFF IN THE LATE EVENING. SATURDAY THROUGH TUESDAY
WILL SEE THE UPPER LOW SLOWLY SINK SOUTH ALONG THE BRITISH COLUMBIA
COAST AND ENDING UP OFF THE OLYMPIC PENINSULA ON MONDAY AND THEN
MOVE ASHORE OVER THE OLYMPIC PENINSULA ON TUESDAY. OUR AREA WILL BE
UNDER A TROUGH THROUGH THIS PERIOD WITH A SOUTH TO SOUTHWEST FLOW
OVER THE AREA. THIS FLOW WILL CARRY MOISTURE INTO THE AREA AND ALONG
WITH INSTABILITY FROM DAYTIME HEATING WILL GIVE CENTRAL OREGON, THE
EASTERN MOUNTAINS AND THE CASCADES A SLIGHT CHANCE OF THUNDERSTORMS
EACH AFTERNOON AND EVENING, TAPERING OFF TO SHOWERS IN THE LATE
EVENING. SUNDAY WILL SEE GREATER MOISTURE OVER THE AREA AND THE
SLIGHT CHANCE OF THUNDERSTORMS WILL EXPAND INTO IN THE BLUE MOUNTAIN
FOOTHILLS. TEMPERATURES WILL BE NEAR NORMAL WITH HIGHS IN THE MID
80S TO LOWER 90S WITH 70S AND LOWER 80S IN THE MOUNTAINS.  POLAN
