   NWS STORM PREDICTION CENTER NORMAN OK

   VALID 131200Z - 141200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN AMPLIFIED UPPER FLOW REGIME CONTINUES ACROSS THE U.S. WITH STRONG
   RIDGING IN THE WEST AND LARGE-SCALE TROUGHING IN THE EAST.  A
   SHORTWAVE SYSTEM CURRENTLY TRAVERSING THE WRN RIDGE WILL DROP SWD
   THROUGH THE INTERMOUNTAIN WEST TODAY...AND EVENTUALLY BECOME CUTOFF
   OVER SRN AZ BY THE END OF THE PERIOD. SURFACE HIGH PRESSURE
   SUBSEQUENTLY BUILDS SWD ACROSS THE GREAT BASIN...INCREASING THE
   OFFSHORE PRESSURE GRADIENT OVER SRN CA. 
   
   FARTHER TO THE EAST...A SHORTWAVE TROUGH WILL MOVE FROM THE LOWER
   MISSISSIPPI VALLEY TWD THE MID ATLANTIC REGION...INITIATING SURFACE
   CYCLOGENESIS ALONG THE ATLANTIC COAST. RAIN AND SNOW WILL DEVELOP IN
   THE MID ATLANTIC AREA TODAY...EXTENDING NWWD TOWARD THE GREAT LAKES.
    SURFACE HIGH PRESSURE OVER THE SRN PLAINS WILL MAINTAIN THE DRY
   CONTINENTAL AIRMASS OVER THE SOUTHEAST.
   
   ...SRN CA...
   SURFACE HIGH PRESSURE WILL DEVELOP SWD ACROSS THE GREAT BASIN
   TODAY...INCREASING THE OFFSHORE PRESSURE GRADIENT THROUGH THE
   PERIOD. AS THE UPPER RIDGE BUILDS INLAND IN THE PACIFIC NORTHWEST
   AND THE CUTOFF LOW DEVELOPS OVER SRN AZ...WINDS ALOFT TURN MORE
   NLY/NELY THROUGH CNTRL/SRN CA.  OFFSHORE SURFACE WINDS AT 15 TO 30
   MPH ARE EXPECTED IN THE WIND PRONE AREAS THIS MORNING AND AGAIN
   MONDAY MORNING...GUSTING AS HIGH AS 45 MPH IN FAVORABLE PASSES AND
   CANYONS.  THE LOW LEVEL AIRMASS IS NOT PARTICULARLY DRY
   HOWEVER...AND MINIMUM RH SHOULD REMAIN AT OR ABOVE 15-20 PERCENT.
   
   ...ERN AL/SRN GA/FL PANHANDLE...
   SURFACE HIGH PRESSURE CENTERED OVER SERN OK THIS AFTERNOON MAINTAINS
   A NWLY FLOW OF CONTINENTAL AIR ACROSS THE SOUTHEAST.  PORTIONS OF
   AL...GA...AND THE FL PANHANDLE WILL SEE MINIMUM RH DIP TO AROUND 35
   PERCENT FOR TWO OR THREE HOURS THIS AFTERNOON. GIVEN THE MODEST
   PRESSURE GRADIENT...SURFACE WINDS SHOULD REMAIN LIGHT AND GENERALLY
   AT OR BELOW 10 MPH.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0404 AM CST SUN JAN 13 2008
   
   VALID 141200Z - 151200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   THE UPPER PATTERN BECOMES MORE CONVOLUTED MONDAY...AS A RELATIVELY
   STRONG TROUGH MOVING INTO THE PACIFIC NORTHWEST FORCES THE UPPER
   RIDGE EWD INTO THE NRN PLAINS...AND THE CUTOFF LOW OVER SRN AZ DROPS
   SWD INTO NWRN MEXICO. A LARGE-SCALE TROUGH WILL REMAIN OVER THE NERN
   CONUS...WITH ZONAL FLOW THROUGH THE SOUTHEAST. A LARGE AREA OF
   SURFACE HIGH PRESSURE COVERS MUCH OF THE PLAINS...PUSHING A VERY DRY
   AND COOL AIRMASS INTO THE SERN U.S.  IN THE WEST...THE SURFACE HIGH
   RESPONSIBLE FOR THE RECENT OFFSHORE WINDS IN SRN CA MOVES TWD THE
   CNTRL ROCKIES...CAUSING THE OFFSHORE GRADIENT TO GRADUALLY WEAKEN.
   
   ...SRN CA...
   THE SURFACE PRESSURE GRADIENT CONTINUES TO SUPPORT OFFSHORE FLOW
   MONDAY...WITH THE GRADIENT GRADUALLY WEAKENING AS THE SURFACE HIGH
   MOVES INTO THE CNTRL ROCKIES MONDAY AFTERNOON.  THE FLOW ALOFT WILL
   REMAIN NELY...BUT DECREASES AS THE UPPER LEVEL CUTOFF DROPS SWD INTO
   NWRN MEXICO. WIND PRONE AREAS WILL AGAIN SEE ELY/NELY SURFACE WINDS
   OF 15 TO 30 MPH...GUSTING TO 40 MPH IN TERRAIN FAVORABLE LOCATIONS
   MONDAY MORNING.  DESPITE THE RETREATING SURFACE HIGH...THE AIRMASS
   CONTINUES TO DRY WITH A MINIMUM RH AROUND 15 PERCENT MONDAY
   AFTERNOON.  
   
   ...SRN MS/SRN AL/SRN GA/INTERIOR FL...
   A COOL BUT VERY DRY AIRMASS WITH DEWPOINTS IN THE 20S TO LOWER 30S
   WILL SPREAD ACROSS THE SOUTHEAST MONDAY. WINDS SHOULD BE LIGHT AND
   GENERALLY BELOW 10 MPH...BUT AFTERNOON TEMPERATURES IN THE 50S TO
   MID 60S WILL RESULT IN AN EXTENDED PERIOD OF RH AS LOW AS 25 PERCENT
   MONDAY AFTERNOON.
   
   ...SRN AZ...
   NELY/ELY SURFACE WINDS OF 15 TO 25 MPH ARE EXPECTED AS THE SURFACE
   HIGH SHIFTS EWD TWD THE CNTRL ROCKIES. THE AIRMASS WILL BE
   MODERATELY DRY...WITH A MINIMUM RH AROUND 15 TO 20 PERCENT DURING
   THE AFTERNOON.  AFTERNOON TEMPERATURES WILL BE NEAR NORMAL...AND
   CLIMB ABOVE 60F OVER THE LOWER DESERTS OF SCNTRL/SWRN AZ.
