   .PREV DISCUSSION... /ISSUED 0454 AM CDT SAT JUL 04 2015/

   ...SYNOPSIS...
   HIGH-OVER-LOW BLOCK ACROSS THE EASTERN PACIFIC OCEAN WILL CONTINUE
   THROUGH THE FORECAST PERIOD. ACROSS WESTERN NORTH AMERICA...THE
   TROUGH-OVER-RIDGE PATTERN WILL WEAKEN AS THE NORTHERN TROUGH MOVES
   EAST AND THE SUB-TROPICAL RIDGE DE-AMPLIFIES SLIGHTLY.

   FARTHER EAST...REMNANT FRONT ACROSS THE SOUTHERN/EASTERN UNITED
   STATES WILL ONCE AGAIN SUPPORT SHOWERS/THUNDERSTORMS. ADDITIONAL
   SHOWERS/THUNDERSTORMS WILL BE POSSIBLE ACROSS THE NORTHERN PLAINS AS
   A SURFACE FRONT ASSOCIATED WITH THE AFOREMENTIONED CANADIAN
   MID-LEVEL TROUGH BEGINS TO MOVE SOUTH/EAST.

   ...NORTH-CENTRAL OREGON NORTHWARD INTO CENTRAL AND EASTERN
   WASHINGTON...
   MID-LEVEL WINDS WILL VEER FROM WEST-TO-NORTH AND SURFACE WINDS WILL
   VEER FROM WEST-TO-NORTHEAST IN RESPONSE TO THE AFOREMENTIONED
   WESTERN CANADIAN TROUGH MOVING EAST AND THE SUB-TROPICAL RIDGE
   DE-AMPLIFYING. DESPITE THE WEAKENING DOWNSLOPE FLOW THROUGH THE
   FORECAST PERIOD...STRONG/GUSTY SURFACE WINDS WILL REMAIN POSSIBLE AS
   THE SURFACE-PRESSURE GRADIENT REORIENTS ITSELF IN RESPONSE TO A
   SURFACE-HIGH PRESSURE BUILDING INTO WESTERN MONTANA AND THE THERMAL
   TROUGH SHIFTING INTO EASTERN IDAHO. WITH AFTERNOON RELATIVE-HUMIDITY
   VALUES EXPECTED TO FALL INTO THE TEENS TO LOW 20S
   PERCENT...ELEVATED-TO-LOCALLY CRITICAL FIRE-WEATHER CONDITIONS WILL
   ONCE AGAIN BE POSSIBLE DESPITE A SHIFT IN WIND DIRECTION.

   ...GREAT BASIN...SIERRA MOUNTAINS...NORTHERN CALIFORNIA...AND
   SOUTHERN OREGON...
   ANOTHER DAY OF SHOWERS/THUNDERSTORMS WILL BE POSSIBLE AS MID-LEVEL
   MOISTURE REMAINS ACROSS THIS AREA. PRECIPITABLE-WATER VALUES REMAIN
   AROUND ONE INCH OR GREATER...WHICH WOULD SUPPORT WETTING RAINS
   WITHIN THUNDERSTORM CORES. HOWEVER...AS IS THE CASE ON
   DAY-1/SATURDAY...DESPITE LOCALIZED WETTING RAIN
   POTENTIAL...RECEPTIVE FUELS ACROSS THE AREA WILL RESULT IN THE
   POTENTIAL FOR NEW LIGHTNING-INDUCED FIRES...ESPECIALLY OUTSIDE OF
   THUNDERSTORM CORES.
