   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0139 AM CST SUN MAR 09 2008
   
   VALID 091200Z - 101200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   DIGGING UPSTREAM JET STREAK OVER THE GREAT BASIN WILL SUPPORT
   INTENSIFICATION OF MIDLEVEL TROUGH WHICH WILL PROGRESS SEWD THROUGH
   THE SRN ROCKIES INTO THE SRN PLAINS DURING THE DAY ONE PERIOD. IN
   THE LOW LEVELS...WEAK CYCLOGENESIS IS FORECAST OVER THE LOWER RIO
   GRANDE VALLEY WITH QUASI-STATIONARY FRONT OR INVERTED TROUGH
   BECOMING INCREASINGLY WELL DEFINED FROM SWRN TX INTO THE NWRN OR
   N-CNTRL PART OF THE STATE.
   
   ...LOWER CO RIVER VALLEY...
   UPPER LOW PRESSURE ACROSS THE GREAT BASIN WILL CONTINUE TO MOVE SEWD
   INTO TX TODAY. HIGH PRESSURE WILL STRENGTHEN OVER THE WEST COAST
   WITH A DRY NORTHERLY FLOW THROUGH THE LOWER CO RIVER VALLEY. JET
   AXIS CURRENTLY LOCATED OVER THE AFOREMENTIONED AREAS WILL CONTINUE
   TO SHIFT SEWD WITH THE MAIN TROUGH AXIS...AND ALTHOUGH CURRENT
   OBSERVATIONS SHOW WIND SPEEDS OF 15 TO 20 MPH...EXPECT THAT PRESSURE
   GRADIENT WILL GRADUALLY RELAX THROUGH THE DAY...WITH WINDS
   DECREASING THROUGH LATE MORNING AND EARLY AFTERNOON. ALTHOUGH
   STRONGER WINDS MAY BE POSSIBLE THROUGH THE CO RIVER VALLEY DUE TO
   CHANNELING EFFECTS...WINDS ARE GENERALLY EXPECTED TO REMAIN BELOW
   CRITICAL THRESHOLDS AT THIS TIME.
   
   MINIMUM RELATIVE HUMIDITIES IN THE TEENS WITH SINGLE DIGITS IN THE
   LOWER VALLEYS WILL BE POSSIBLE IN THE AFTERNOON.
   
   ...SWRN TX...
   AN UPPER TROUGH WILL SHIFT INTO SWRN TX TODAY...WITH PREDOMINANT
   WEST TO SOUTHWESTERLY FLOW. IN THE WESTERN MOST PORTIONS OF
   TX...EXPECT DOWNSLOPING/ADIABATIC DRYING AND WARMING TO ALLOW
   RELATIVE HUMIDITIES TO DROP INTO THE TEENS. SOME DEGREE OF MID-LEVEL
   COOLING/MOISTENING IS EXPECTED ACROSS THE TRANSPECOS AND CAPROCK
   REGIONS...AND WEAK ASCENT MAY SUPPORT DEVELOPMENT OF ISOLATED DRY
   THUNDERSTORMS.
   
   MAIN LIMITING FACTOR TO A CRITICAL DESIGNATION WILL BE MARGINAL
   WINDS...AND VERY ISOLATED NATURE OF POTENTIAL DRY THUNDERSTORMS.
   
   ...SERN STATES...
   SURFACE HIGH PRESSURE WILL CONTINUE TO BUILD OVER THE AREA
   TODAY...WITH WINDS SHIFTING FROM WESTERLY TO NORTHWESTERLY THROUGH
   THE DAY AS A LOW PRESSURE CENTER OVER NEW ENGLAND CONTINUES TO MOVE
   NORTHEASTWARD. AS THIS LOW EXITS...THE GRADIENT WILL WEAKEN OVER THE
   SOUTHEAST AND WINDS WILL NOT MEET CRITICAL THRESHOLDS.
   
   DESPITE THIS...CURRENT WV IMAGERY SHOWS EXPANSIVE SWATH OF DRY AIR
   OVER THE SERN STATES. AFTERNOON RELATIVE HUMIDITIES WILL DROP INTO
   THE 20S INLAND AND IN THE LOWER 30S CLOSER TO THE COAST FOR EXTENDED
   DURATIONS. EXPECT THE GREATEST THREAT TO BE ACROSS CENTRAL GA AND
   WESTERN PORTIONS OF THE PANHANDLE WHERE LESS RAINFALL HAS BEEN
   RECEIVED RECENTLY AND DROUGHT CONDITIONS PERSIST.
   
   LIGHT WINDS WILL LIMIT DESIGNATION OF CRITICAL FIRE WEATHER AREA.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0304 AM CDT SUN MAR 09 2008
   
   VALID 101200Z - 111200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER TROUGH AND COOLER TEMPERATURES WILL DOMINATE IN THE EAST.
   MEANWHILE...A SHORT WAVE OVER TX WILL CONTINUE TO MOVE SEWD AND
   DEAMPLIFY. A SECOND UPPER SHORT WAVE WILL MOVE INTO THE FOUR CORNERS
   REGION WHILE HIGH PRESSURE DEAMPLIFIES OVER THE INTERMOUNTAIN WEST.
   A DEEP UPPER LOW WILL BEGIN TO MOVE INTO THE PACIFIC
   NORTHWEST...WITH RAIN AND BREEZY WINDS INCREASING AHEAD OF THE
   SYSTEM.
   
   ...SRN NV/CA/AZ/NM...
   A DEEP UPPER TROUGH MOVING INTO THE PACIFIC NORTHWEST WILL SHIFT
   WINDS ALONG THE COAST TO SOUTHWESTERLY THROUGH THE DAY. ALTHOUGH
   RELATIVE HUMIDITIES WILL DROP INTO THE TEENS AND SINGLE DIGITS
   ACROSS THE AFOREMENTIONED AREA...LIGHT AND VARIABLE WINDS CAN BE
   EXPECTED...LIMITING DESIGNATION OF A CRITICAL THREAT.
   
   ...SERN STATES...
   SURFACE HIGH PRESSURE CENTERED NEAR SRN IL/IN WILL DOMINATE...WHILE
   A WEAK SURFACE TROUGH WILL DEVELOP ON THE LEE OF THE APPALACHIANS.
   DRY CONDITIONS WILL PERSIST...WITH AFTERNOON RELATIVE HUMIDITIES
   DROPPING INTO THE MID 20S AND LOWER 30S ACROSS MUCH OF THE AREA.
   MAIN LOW LEVEL FLOW AROUND THE PERIPHERY OF THE HIGH WILL ALLOW SOME
   MOISTURE RETURN NEAR COASTAL AREAS...LIMITING THE EXTENT OF DRY
   CONDITIONS. LIGHT AND VARIABLE SURFACE WINDS WILL HINDER DESIGNATION
   OF CRITICAL AREA.
