AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
230 PM PDT SUN AUG 11 2013

.SHORT TERM...TONIGHT THROUGH WEDNESDAY AFTERNOON...SLOW MOVING
UPPER LEVEL LOW PRESSURE SYSTEM WILL KEEP FORECAST AREA UNDER A
THREAT OF DIURNAL THUNDERSTORMS TUESDAY EVENING WITH BEST CHANCE OF
A STORM OVER THE BLUE MOUNTAINS THROUGH TUESDAY EVENING AND ALONG
THE EAST SLOPES OF THE WASHINGTON CASCADES MONDAY AFTERNOON INTO
EARLY MONDAY EVENING. AS THE LOW THE LOW MOVES NORTHWEST TO
VANCOUVER ISLAND LATE MONDAY POPS WILL DECREASE AREAWIDE , BUT THE
BLUE MOUNTAINS WILL STILL HAVE A SLIGHT CHANCE OF AFTERNOON/EVENING
THUNDERSTORMS ON TUESDAY. HIGH PRESSURE BUILDS OVER REGION ON
WEDNESDAY FOR DRY CONDITIONS.   POLAN

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY. A RIDGE OF HIGH
PRESSURE WILL CONTINUE TO INFLUENCE MOST OF THE REGION INTO THURSDAY
WITH MOSTLY DRY CONDITIONS. HOWEVER A LOW PRESSURE SYSTEM WILL
APPROACH THE TWO STATE AREA AND MAY PRODUCE A FEW SHOWERS OR
THUNDERSTORMS OVER THE EAST SLOPES OF THE WASHINGTON CASCADES
THURSDAY AFTERNOON AND EVENING. AS THE HIGH PRESSURE SLIPS EAST THE
LOW WILL SPREAD ADDITIONAL MOISTURE INTO THE REGION AND WILL
INCREASE THE THREAT FOR THUNDERSTORMS ACROSS THE ENTIRE AREA FRIDAY.
AS THIS SYSTEM PUSHES EAST SOME DRYING IS LIKELY FOR WA/OR ON
SATURDAY FROM WEST TO EAST. BY SUNDAY A RETURN TO MOSTLY SUNNY SKIES
IS EXPECTED. TEMPERATURES THROUGH THE PERIOD SHOULD BE NEAR NORMAL
BUT WITH SLIGHTLY COOLER TEMPERATURES POSSIBLE INTO THE WEEKEND.

&&

.AVIATION...LOW PRESSURE OFF THE PACNW COAST WILL COMBINE WITH
DAYTIME HEATING TO PRODUCE SOME THUNDERSTORMS THIS AFTERNOON AND
EVENING THAT COULD IMPACT EACH TAF SITE. VFR CONDITIONS ARE LIKELY.
HOWEVER THE DEVELOPMENT OF THUNDERSTORMS COULD MOVE NEAR ALL TAF
SITES AND CREATE MVFR CEILINGS INTO THIS EVENING. THE THREAT OF
THUNDERSTORMS SHOULD BE ON THE DECREASE AFTER 06Z.

&&

.FIRE WEATHER...A LOW PRESSURE SYSTEM MOVING UP THE COAST WILL
CONTINUE TO SEND MOIST UNSTABLE AIR INTO THE REGION. RED FLAG

ABUNDANT LIGHTNING FOR PORTIONS OF NORTHEAST OREGON AND SOUTHEAST
WASHINGTON. SIGNIFICANT LIGHTNING IS NO LONGER EXPECTED ACROSS
CENTRAL OREGON. ANY STORMS THAT DO DEVELOP WILL INITIALLY HAVE
MINIMAL RAINFALL...BUT WILL BECOME INCREASINGLY WETTER...ESPECIALLY
UNDER THE THUNDERSTORM CORES. HOWEVER...THE ABUNDANT LIGHTNING COULD
STILL RESULT IN NEW FIRE STARTS DUE TO DRY FUELS. THE LOW WILL MOVE
NORTH ON MONDAY...BUT ANOTHER SHORTWAVE WILL BRING A CHANCE OF
SHOWERS AND THUNDERSTORMS TO CENTRAL AND NORTHEAST OREGON AND
SOUTHEAST WASHINGTON ONCE AGAIN. FIRE WEATHER WATCHES WILL THEREFORE
BE ISSUED FOR THESE AREA FOR MONDAY AFTERNOON AND EVENING.  TRIMARCO

&&

.HYDROLOGY...A FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH 11PM
