   ...NO SVR TSTM AREAS FORECAST...
   
   ...SYNOPSIS...
   
   IN THE WEST...AN UPPER-LEVEL LOW AND ASSOCIATED TROUGH WILL MOVE
   SLOWLY SEWD OFF OF THE CA COAST. MEANWHILE...IN THE EAST...A
   POWERFUL LOW PRESSURE SYSTEM OFF OF THE MID-ATLANTIC COAST WILL
   CONTINUE MOVING NEWD AS A SECONDARY UPPER SYSTEM DIGS INTO THE ERN
   GREAT LAKES REGION. BETWEEN THESE SYSTEMS ACROSS THE MIDWEST...AN
   UPPER RIDGE WILL REMAIN IN PLACE. AT THE SURFACE...LOW PRESSURE IN
   THE LEE OF THE ROCKIES WILL BEGIN TO DRAW MOISTURE NWD FROM THE GULF
   OF MEXICO...BUT THIS MOISTURE WILL MAKE LITTLE PROGRESS ON D1/THU.
   GENERALLY DRY AND STABLE CONDITIONS WILL PREVAIL ACROSS THE
   CONUS...WITH A MINIMAL THUNDERSTORM THREAT CONFINED TO NEAR AND OFF
   OF THE CA COAST AND NO SEVERE CONVECTION EXPECTED. 
   
   ...CA COASTAL REGION...
   
   WITH THE UPPER LOW EXPECTED TO REMAIN OFFSHORE THROUGH THE
   PERIOD...ANY THUNDERSTORM THREAT IS EXPECTED TO REMAIN NEAR AND OFF
   OF THE CA COAST...IN CLOSER PROXIMITY TO STRONGER ASCENT AND COLDER
   MIDLEVEL TEMPS. EVEN IN THIS AREA...WEAK MUCAPE AOB 200 J/KG AND
   RELATIVELY WARM EL TEMPS WILL LIKELY KEEP THUNDERSTORM COVERAGE
   ISOLATED AT BEST.
