   ...SYNOPSIS...
   AMPLIFIED MID LEVEL FLOW ACROSS THE CONUS ON WEDNESDAY WILL FEATURE
   A DEVELOPING CLOSED LOW OVER THE NORTHEAST U.S. DOWNSTREAM FROM A
   LARGE SCALE RIDGE EXTENDING FROM THE SOUTHWEST THROUGH THE NRN HIGH
   PLAINS. A STRONG SHORT WAVE TROUGH...CURRENTLY EVIDENT ON SATELLITE
   IMAGERY NEAR 35N 144W...IS FCST TO LIFT ENEWD TOWARD THE PACIFIC
   NORTHWEST COAST BY WEDNESDAY AFTERNOON. THIS IMPULSE WILL DRIVE A
   COLD FRONT INLAND ACROSS WA/ORE...AND NRN ID DURING THE LATTER HALF
   OF THE PERIOD.
   
   ...PACIFIC NORTHWEST...
   STRONG HEIGHT FALLS OF 60-120M ARE FORECAST TO ACCOMPANY THE
   BREAKDOWN OF THE UPPER RIDGE ACROSS THE NORTHWEST. DYNAMIC FORCING
   FOR ASCENT ALONG AND BEHIND THE COLD FRONT WILL ACT ON POCKETS OF
   RESIDUAL WARMTH AND MOISTURE IN THE BOUNDARY LAYER TO RESULT IN
   MUCAPE VALUES OF 150-250 J/KG ACROSS PARTS OF THE REGION. ENSEMBLE
   FCSTS SUGGEST INSTABILITY AND FORCING SHOULD BE SUFFICIENT FOR
   WIDELY SCATTERED THUNDERSTORMS...ESPECIALLY WITHIN THE UNSTABLE AND
   UPSLOPE POST-FRONTAL FLOW ACROSS WRN WA/ORE.
