.PREV DISCUSSION... /ISSUED 0329 AM CDT TUE JUL 29 2014/

...SYNOPSIS...
THE UPPER AIR PATTERN REMAINS UNCHANGED WITH THE TROUGH IN THE EAST
AND A RIDGE IN THE WEST.  WEAK SWLY FLOW WILL COVER THE OREGON AND
WASHINGTON AREA WITH A MIX OF WET AND DRY THUNDERSTORMS THIS
AFTERNOON INTO EVENING.  GIVEN THE DRY FUELS AND THAT SOME OF THE
STORMS MAY BE DRY...AN ISOLATED DRY THUNDERSTORM AREA WILL COVER
PARTS OF THE NW.

...S-CNTRL AND SERN OREGON...NRN CA AND NWRN NV...
WHILE MOISTURE HAS INCREASED A LITTLE IN THE PACIFIC NW...PW VALUES
WILL REMAIN RELATIVELY LOW...AROUND 0.75 INCH.  SOME STORMS IN THE
AREA WILL PRODUCE WETTING RAINS...ESPECIALLY WITH SLOW STORM MOTION
DUE TO LIGHT WINDS.  HOWEVER...WITH VERY DRY FUELS AND GIVEN THE
MARGINAL AMOUNT OF MOISTURE WITH HIGHS IN THE 80S TO LOW 90S WITH
SURFACE HUMIDITY FROM 15 TO 20 PERCENT...SOME OF THE STORMS MAY
PRODUCE VERY LITTLE WETTING RAINS.  IN ADDITION...LIGHTNING OUTSIDE
OF RAIN CORES MAY CAUSE NEW IGNITIONS.

ELSEWHERE...STORMS WITH MAINLY WETTING RAINS ARE EXPECTED OVER MUCH
OF THE WEST WHERE MOISTURE VALUES ARE HIGHER.
