   ...PACIFIC NW...
   
   A SERIES OF WEAK IMPULSES WILL TRANSLATE ACROSS THE ERN PACIFIC INTO
   THE NWRN CONUS OVER THE NEXT FEW DAYS AS HEIGHTS GRADUALLY LOWER AND
   THE PRIMARY JET CORE SAGS SWD INTO CA.  DEEP WLY ONSHORE FLOW WILL
   MAINTAIN WEAK BUOYANCY ALONG THE COAST AS MARINE LAYER IS FORCED
   AGAINST THE CASCADE RANGE.  FORECAST SOUNDINGS ALONG THE COAST
   SUGGEST LOW-MID LEVEL LAPSE RATES WILL REMAIN SUFFICIENTLY STEEP FOR
   ROBUST UPDRAFTS AND POSSIBLE THUNDERSTORM DEVELOPMENT.  WITH SBCAPE
   VALUES LIKELY ON THE ORDER OF 200-300 J/KG...CLOUD TOPS COULD EASILY
   EXCEED LEVELS NECESSARY FOR LIGHTNING DISCHARGE.
   
   ...ELSEWHERE...
   
   DRY CONTINENTAL AIRMASS WILL CONTINUE ACROSS MOST OF THE
   ROCKIES...EAST TO THE ATLANTIC COAST.  THE ONLY POSSIBLE EXCEPTION
   WHERE ISOLATED THUNDERSTORMS COULD DEVELOP WILL BE AHEAD OF A STRONG
   SHORTWAVE TROUGH OVER NRN MEXICO.  HOWEVER...THIS FEATURE WILL NOT
   AFFECT TX UNTIL LATER IN THE DAY2 PERIOD.
