   VALID 251200Z - 261200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A STRONG UPPER TROUGH WILL MOVE EWD ACROSS THE SERN STATES TODAY. IN
   THE WAKE OF THIS SYSTEM...BREEZY NWLY WINDS WILL OCCUR OVER THE
   LOWER MS VALLEY. HOWEVER...RH READINGS WILL NOT BE SUFFICIENTLY LOW
   /35-40 PERCENT/ FOR A CRITICAL FIRE WEATHER THREAT. UPPER RIDGING
   WILL BUILD OVER THE SRN PLAINS...PROVIDING FOR MILD TEMPERATURES AND
   LOW RH READINGS...BUT MUCH WEAKER WINDS THAN OCCURRED YESTERDAY.
   FURTHER WEST...ANOTHER UPPER TROUGH WILL MOVE INTO WEST COAST BY THE
   END OF THE PERIOD. AS A RESULT...INCREASING ONSHORE FLOW WILL AID IN
   MODERATING RH READINGS AND CHANCES OF LIGHT RAIN OVER SRN CA.

Day 2 Fire Weather Forecast graphic

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0212 AM CST SUN DEC 25 2005
   
   VALID 261200Z - 271200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SRN PLAINS...
   
   ...SYNOPSIS...
   A COMPACT UPPER TROUGH WILL MOVE EWD FROM THE WEST COAST INTO THE
   SRN/CENTRAL ROCKIES. AHEAD OF THIS SYSTEM...THE SURFACE LEE TROUGH
   WILL INTENSIFY OVER THE HIGH PLAINS AS MID LEVEL WLY FLOW INCREASES.
   THE RESULT WILL BE INCREASING SURFACE SSWLY WINDS OVER THE PLAINS.
   IN ADDITION...WARM TEMPERATURES IN THE 60S TO 70S WILL COMBINE WITH
   DEWPTS IN THE 20S AND 30S TO PROVIDE FOR MIN RH READINGS FROM 15-25
   PERCENT...CREATING CRITICAL FIRE WEATHER CONDITIONS. IN THE WAKE OF
   THIS UPPER TROUGH...WEAK OFFSHORE FLOW IS ANTICIPATED TO DEVELOP
   OVER SRN/CENTRAL CA. RECENT PRECIPITATION IS EXPECTED TO LIMIT ANY
   FIRE WEATHER CONCERNS IN THIS AREA. ELSEWHERE ACROSS THE
   NATION...MILD TEMPERATURES AND MODERATE RH READINGS WILL BE
   PREDOMINANT AS A GENERAL ZONAL UPPER LEVEL PATTERN WILL KEEP ARCTIC
   AIR IN CANADA.
   
   ...CRITICAL FIRE WEATHER AREA 1 - SERN NM...WRN/CENTRAL TX AND
   SRN/CENTRAL OK...
   
   PRIMARY CONDITIONS: SUSTAINED S-SWLY WINDS FROM 20-25 MPH WITH GUSTS
   UP TO 30 MPH...MIN RH READINGS FROM 15-25 PERCENT
   
   INTENSIFYING LEE TROUGH OVER THE SRN HIGH PLAINS...ALONG WITH
   DEPARTING AREA OF HIGH PRESSURE OVER THE NRN GULF OF MEXICO...WILL
   SUPPORT AN INCREASING PRESSURE GRADIENT OVER THE LOWER PLAINS OF
   CENTRAL TX NWD INTO SRN/CENTRAL OK. SSWLY WINDS WILL INCREASE
   THROUGH THE DAY AS A RESULT WITH SPEEDS OVER 20 MPH COMMON BY
   AFTERNOON. IN ADDITION...MID LEVEL WLY FLOW WILL INCREASE OVER THE
   SRN ROCKIES AHEAD OF APPROACHING SHORTWAVE TROUGH. THIS WILL AID IN
   INCREASING SURFACE WSWLY WINDS OVER THE SRN HIGH PLAINS AND ADJACENT
   MTNS OF SWRN TX/SERN NM. A WARM AIRMASS WILL BE IN PLACE OVER THE
   ENTIRE SRN PLAINS...WITH HIGH TEMPERATURES AVERAGING 20-25 DEGREES
   ABOVE NORMAL. THIS ANOMALOUS WARMTH COMBINED WITH LITTLE RAINFALL IN
   THE LAST 6 WEEKS AND BREEZY CONDITIONS WILL SUPPORT A CRITICAL FIRE
   WEATHER THREAT. WEAKER PRESSURE GRADIENT NEAR THE LEE LOW CENTER
   OVER NWRN OK AND THE TX PANHANDLE WILL PRECLUDE SUFFICIENTLY STRONG
   WINDS FOR A CRITICAL FIRE WEATHER THREAT IN THIS AREA. DUE TO THE
   DEEPENING NATURE OF THE LEE TROUGH/LOW THROUGH THE DAY...SURFACE
   WINDS ARE NOT FORECAST TO DIMINISH MUCH AFTER DARK.
   HOWEVER...COOLING TEMPERATURES WILL AID IN CRITICAL CONDITIONS
   ENDING SHORTLY AFTER SUNSET.
   
   ...PORTIONS OF SRN CA...
   WEAK TO MODERATE NLY FLOW WILL DEVELOP IN THE MTNS N-NW OF THE LA
   BASIN LATE IN THE PERIOD AS SURFACE HIGH PRESSURE BUILDS SWD THROUGH
   CENTRAL CA VALLEY/COAST AND LOW PRESSURE REMAINS OFF THE SRN CA
   COAST. GIVEN GOOD CHANCES OF PRECIP OVER MUCH OF THE AREA EARLY ON
   DAY 2...A CRITICAL FIRE WEATHER THREAT IS NOT EXPECTED.
