   ..COOK.. 07/03/2015

   .PREV DISCUSSION... /ISSUED 0437 AM CDT FRI JUL 03 2015/

   ...SYNOPSIS...
   HIGH-OVER-LOW MID-/UPPER-LEVEL PATTERN WILL DEVELOP ACROSS THE
   EASTERN PACIFIC OCEAN WITH A DOWNSTREAM TROUGH-OVER-RIDGE LOCATED
   ACROSS WESTERN NORTH AMERICA. FARTHER DOWNSTREAM /ACROSS EASTERN
   NORTH AMERICA/ MEAN TROUGHING WILL PERSIST. GENERALLY HOT/DRY
   CONDITIONS WILL PERSIST ACROSS MUCH OF THE WEST...WITH COOLER/WETTER
   CONDITIONS FOUND ACROSS AREAS EAST OF THE ROCKIES.

   ...CENTRAL OREGON NORTHWARD INTO CENTRAL WASHINGTON...
   SIMILAR CONDITIONS AS DAY-1/FRIDAY WILL CONTINUE THROUGH SATURDAY.
   STRONG HEATING WILL RESULT IN THE DEVELOPMENT OF A
   DEEPLY-MIXED-BOUNDARY LAYER AND MINIMUM RELATIVE-HUMIDITY VALUES IN
   THE TEENS-TO-MID 20S PERCENT RANGE. A SHORT-WAVE TROUGH EMBEDDED IN
   THE LARGER WESTERN CANADIAN TROUGH ACROSS ALBERTA WILL REINFORCE THE
   LEE TROUGH EAST OF THE CASCADES ALLOWING FOR STRONG SURFACE WINDS TO
   DEVELOP. ONE CAVEAT IS THE DEGREE TO WHICH CLOUD COVER /ASSOCIATED
   WITH THE APPROACHING SHORT-WAVE TROUGH OR LEFT OVER FROM
   DAY-1/FRIDAY CONVECTIVE ELEMENTS/ MAY LIMIT OVERALL HEATING AND KEEP
   RELATIVE-HUMIDITY VALUES HIGHER THAN DAY-1/FRIDAY. EITHER
   WAY...GIVEN THE PREEXISTING HOT/DRY CONDITIONS ACROSS THE
   AREA...ELEVATED-T0-LOCALLY CRITICAL FIRE-WEATHER CONDITIONS WILL BE
   POSSIBLE.

   ...GREAT BASIN...SIERRA MOUNTAINS...AND FAR SOUTHERN OREGON...
   ONCE AGAIN THUNDERSTORMS WILL BE POSSIBLE IN THIS REGION AS
   VORTICITY MAXIMA CONTINUE TO ROTATE AROUND THE PERIPHERY OF THE
   WESTERN RIDGE. PRECIPITABLE-WATER VALUES AROUND OR GREATER THAN ONE
   INCH WILL SUPPORT WET THUNDERSTORMS...ALTHOUGH LIGHTNING STRIKES
   OUTSIDE OF THUNDERSTORM CORES WILL STILL POSE A RISK FOR FIRE
   STARTS. ADDITIONALLY...THE DRY...DEEPLY-MIXED-BOUNDARY LAYER WILL
   POSE A DOWNBURST THREAT WITH THE STRONGEST STORMS. PLEASE SEE THE
   LATEST SPC DAY-2 CONVECTIVE OUTLOOK FOR ADDITIONALLY INFORMATION
   REGARDING THUNDERSTORM POTENTIAL IN THIS AREA.
