   .PREV DISCUSSION... /ISSUED 0334 AM CDT WED JUL 30 2014/

   ...SYNOPSIS...
   LITTLE CHANGE IN THE UPPER-AIR PATTERN IS EXPECTED WITH A TROUGH
   OVER THE EAST AND A WESTERN RIDGE EXTENDING NWD INTO THE NRN
   ROCKIES.  ONE DISTURBANCE MOVING SEWD THROUGH THE CENTRAL U.S. IS
   EXPECTED TO PRODUCE HEAVY RAIN ACROSS CO/KS AND OK.  ALTHOUGH IT
   WILL REMAIN WARM TO HOT OVER MOST OF THE WEST...SOME MONSOONAL
   MOISTURE UNDER THE UPPER RIDGE WILL CONTINUE TO PRODUCE
   THUNDERSTORMS WITH MAINLY WETTING RAINS.

   ...SERN HALF OF OREGON...NERN CA...NWRN NV...
   THUNDERSTORMS ARE ONCE AGAIN EXPECTED OVER THIS AREA DURING THE
   PERIOD.  THIS AREA REMAINS ON THE EDGE OF THE HIGHER MOISTURE WITH
   PW VALUES REMAINING AROUND 0.75 INCH.  NAM MODEL SHOWS SOME DRYING
   MAY TAKE PLACE DURING THE AFTERNOON BEFORE A SLIGHT INCREASE IN THE
   PW OVERNIGHT.  FUELS REMAIN VERY DRY ACROSS THE AREA AND AFTERNOON
   HIGHS WILL BE VERY WARM AND SURFACE HUMIDITY WILL GENERALLY BE BELOW
   20 PERCENT.  EVEN THOUGH MANY OF THE STORMS ARE EXPECTED TO PRODUCE
   AT LEAST SOME WETTING RAINS...AS LIGHT WINDS FAVOR SLOW STORM
   SPEEDS...FORECAST SOUNDINGS SUPPORT AT LEAST SOME STORMS WITH VERY
   LITTLE RAINFALL.  HIGH CLOUD BASES AND A DRY SUB-CLOUD LAYER
   INDICATE SOME OF THE RAINFALL WILL EVAPORATE BEFORE REACHING THE
   GROUND...ESPECIALLY FOR STORMS MOVING OFF HIGHER TERRAIN.  ALSO
   LIGHTNING OUTSIDE THE MAIN RAIN CORES MAY PRODUCE IGNITIONS.

   .PREV DISCUSSION... /ISSUED 0406 AM CDT WED JUL 30 2014/

   ...SYNOPSIS...
   THE OVERALL UPPER-AIR PATTERN WILL CHANGE LITTLE ON THURSDAY WITH
   THE UPPER TROUGH IN THE EAST AND THE RIDGE IN THE WEST. 
   THUNDERSTORMS...MOSTLY WITH WETTING RAINS...ARE EXPECTED ACROSS
   PARTS OF THE WEST.

   ...PORTIONS NERN CA...NWRN NV...SERN OREGON AND W-CNTRL/CNTRL ID...
   ALTHOUGH MANY OF THE THUNDERSTORMS IN THE WEST ARE EXPECTED TO
   PRODUCE WETTING RAINFALL...INCLUDING CENTRAL OREGON... THE AREA HAS
   BEEN HIGHLIGHTED AS SOME STORMS ARE LESS LIKELY TO PRODUCE WETTING
   RAINFALL.  WITH FORECAST PW STILL AROUND OR SLIGHTLY BELOW 0.75
   INCH...WARM TO HOT AFTERNOON TEMPERATURES...LOW SURFACE HUMIDITY
   FROM 10 TO 20 PERCENT AND VERY DRY FUELS...WETTING RAINFALL IS LESS
   LIKELY.  THIS AREA WILL HAVE HIGH CLOUD BASES AND A DRY SUB-CLOUD
   LAYER ALONG WITH MARGINAL INSTABILITY AROUND 100 TO 300 J/KG.
