.SHORT TERM...TONIGHT THROUGH WEDNESDAY NIGHT...THE FLASH FLOOD
WATCH FOR NORTHEAST OREGON WILL BE CANCELED SHORTLY AS THE THREAT
FOR WIDESPREAD FLASH FLOODING WILL DECREASE AS THE WEATHER
DISTURBANCE HAS MOVED NORTH AND INSTABILITY WILL DECREASE WITH THE
SUN SETTING. HOWEVER...AN ENERGETIC UPPER LOW PRESSURE SYSTEM WILL
CONTINUE TO BRING SHOWERS AND SOME THUNDERSTORMS WITH HEAVY RAIN
ACROSS THE AREA THIS EVENING.  A LINE OF THUNDERSTORMS MOVED UP THE
YAKIMA VALLEY EARLIER THIS AFTERNOON AND BROUGHT HEAVY RAIN AND
URBAN FLOODING TO YAKIMA AND NEARBY LOCATIONS.  A SMALL AND BRIEF
TORNADO WAS ALSO REPORTED NORTHEAST OF YAKIMA BY SEVERAL SPOTTERS.
THE BAND OF PRECIPITATION AND THUNDERSTORMS THAT BROUGHT THE HEAVY
RAIN TO THE YAKIMA VALLEY IS STILL OVER YAKIMA COUNTY AND IS MOVING
NORTHWARD.  IT IS NOT CURRENTLY CREATING HEAVY RAIN BUT WILL BE
MONITORED FOR A THREAT OF SMALL STREAM AND URBAN FLOODING.  TOMORROW
WILL BE ANOTHER CLOUDY DAY WITH NUMEROUS SHOWERS BUT THERE IS
WARMING ALOFT AND THUNDERSTORMS ARE NOT EXPECTED.  SNOW LEVELS LOWER
TO AROUND 5500 FEET OVERNIGHT TONIGHT BUT WITH LIGHTER PRECIPITATION
ACCUMULATIONS ARE EXPECTED TO BE LESS THAN AN INCH EXCEPT FOR HIGHER
ELEVATIONS.  TUESDAY NIGHT THROUGH WEDNESDAY NIGHT THERE WILL BE A
DRYING TREND AS THE UPPER LOW EXITS THE PACIFIC NORTHWEST.  80

UPPER RIDGE BUILDS OVER THE AREA FOR THE END OF THE WEEK BRINGING
WARMER AND DRIER WEATHER. ECMWF HOLDS ONTO THE RIDGE A LITTLE LONGER
