   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0258 AM CDT THU MAY 21 2009
   
   VALID 221200Z - 231200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   RELATIVELY ZONAL FLOW WILL EXIST ACROSS THE NRN U.S./CANADIAN BORDER
   ON FRI WITH RELATIVELY WEAK WINDS ACROSS MOST OF THE CONUS. AN
   EXCEPTION WILL BE OVER NEW ENGLAND WHICH WILL EXPERIENCE NWLY WINDS
   BEHIND A COLD FRONT...ALONG WITH MODERATELY LOW RH.
   ELSEWHERE...SCATTERED THUNDERSTORMS WILL PERSIST OVER THE FOUR
   CORNERS REGION AS WELL AS THE GREAT BASIN...AND MOST WILL NOT BE
   DRY. PRECIPITATION WILL ALSO EXPAND NWD INTO THE CNTRL GULF COAST
   AND LOWER MS VALLEY AS AN UPPER LOW DRIFTS NWD.
   
   ...NEW ENGLAND...
   A COLD FRONT WILL PASS THROUGH EARLY FRI MORNING...WITH NWLY WINDS
   NEAR 15 MPH SUSTAINED LIKELY. A FEW HIGHER GUSTS TO 20 MPH ARE
   LIKELY OVER ME. WITH HIGHS IN THE 70S F...MIN RH SHOULD DROP WELL
   INTO THE 30 PERCENT RANGE.
   
   ...NV INTO FAR SRN ID...
   A RELATIVELY DRY AIR MASS WILL REMAIN OVER NV BENEATH A WEAK UPPER
   RIDGE WITH MIN RH IN THE TEENS. TO THE NW...A WEAK TROUGH WILL
   WEAKEN THE RIDGE A BIT...AND MAY RESULT IN ADDED ATMOSPHERIC LIFT.
   MOISTURE ASSOCIATED WITH A WEAK UPPER LOW OVER AZ WILL COMBINE WITH
   A WARM AND DRY LAPSE RATE PROFILE ACROSS NV...RESULTING IN ISOLATED
   TO SCATTERED DRY THUNDERSTORMS. AT THIS TIME IT DOES NOT APPEAR
   LIGHTNING STRIKE COVERAGE WILL WARRANT A CRITICAL OUTLOOK...ALTHOUGH
   A DRY SUB CLOUD LAYER SUGGESTS HIGH LIGHTNING IGNITION EFFICIENCIES.
