   RETURN TO SRN CA IN THE WAKE OF THE AFOREMENTIONED TROUGH AND AHEAD
   OF A STRONGER TROUGH THAT WILL APPROACH THE PACIFIC NORTHWEST COAST
   OVERNIGHT. HOWEVER...COOL OVERNIGHT TEMPERATURES WILL PREVENT
   RELATIVE HUMIDITIES FROM FALLING BELOW CRITICAL VALUES.
   
   FARTHER E...AN UPPER LOW IN THE MID MISSISSIPPI VALLEY WILL CONTINUE
   ITS SLOW NEWD MIGRATION. AT THE SURFACE...A COLD FRONT WILL SLOWLY
   PROGRESS SEWD TROUGH GA/NRN FL...REACHING CNTRL FL LATE IN THE

   VALID 191200Z - 201200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER TROUGH WILL WEAKEN AND PROGRESS EWD ACROSS THE ROCKIES AND
   INTO THE CENTRAL STATES OVERNIGHT. AT THE TAIL END OF THIS...A SHORT
   WAVE TROUGH WILL PASS THROUGH THE SWRN STATES AND BRIEF UPPER
   RIDGING WILL BUILD IN BEHIND...LEADING TO WEAK OFFSHORE FLOW/A
   MARGINAL FIRE THREAT ACROSS SRN CA. A PACIFIC UPPER TROUGH WILL
   QUICKLY FOLLOW...BEGINNING TO MOVE ONSHORE OVERNIGHT. WINDS WILL
   SHIFT TO WLY IN ASSOCIATION WITH THE SYSTEM...BRINGING A QUICK END
   TO OFFSHORE FLOW.
   
   MEANWHILE FARTHER E...AN UPPER LOW LINGERING IN THE UPPER MS VALLEY
   WILL FINALLY BEGIN TO EJECT ENEWD THROUGH THE GREAT LAKES
   REGION...DRIVING A COLD FRONT AT THE SURFACE EWD...BECOMING ORIENTED
   SWD THROUGH THE MID ATLANTIC AND SSWWD THROUGH CNTRL FL OVERNIGHT.
   COOL/MOIST CONDITIONS WILL LIMIT THE FIRE THREAT ACROSS MUCH OF THE
   COUNTRY.
   
   ...SRN CA...
   WEAK OFFSHORE FLOW WILL BRIEFLY RETURN TO SRN CA THURSDAY AS AN
   UPPER SHORT WAVE TROUGH PASSES TO THE EAST...AND A SURFACE HIGH
   CENTERED OVER THE INTERMOUNTAIN WEST LEADS TO NELY LOW LEVEL WINDS.
   WARM TEMPERATURES AND LOW RELATIVE HUMIDITIES IN THE TEENS WILL
   ALIGN WITH LOCALLY BREEZY WINDS IN FAVORED CANYONS AND
   PASSES...THOUGH LACK OF MORE APPRECIABLE FLOW WILL PRECLUDE A
   CRITICAL OUTLINE. WINDS WILL QUICKLY SHIFT TO WLY
   OVERNIGHT...ALLOWING RELATIVE HUMIDITIES TO RECOVER.
