   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0334 AM CDT MON JUL 10 2006
   
   VALID 101200Z - 111200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR NERN CA/NWRN NV...
   
   ...SYNOPSIS...
   LONGWAVE TROUGH CONTINUES TO FORM OVER NWRN U.S. WITH INITIAL
   SHORTWAVE AND SURFACE COLD FRONT MOVING THROUGH THE NRN ROCKIES
   TODAY. AS THE UPPER RIDGE IS SUPPRESSED SOUTHWARD WESTERLY FLOW AND
   DRIER PACIFIC AIR BEGIN TO INFILTRATE THE INTERIOR WEST. BREEZY
   CONDITIONS DEVELOP OVER PORTIONS OF THE GREAT BASIN AS THE
   AFOREMENTIONED TROUGH MOVES INLAND...INCREASING THE THREAT OF
   CRITICAL FIRE WEATHER CONDITIONS. SCATTERED THUNDERSTORMS...SOME OF
   THEM DRY...ARE ALSO EXPECTED OVER A LARGE PORTION OF THE INTERIOR
   WEST.
   
   FARTHER EAST...CANADIAN HIGH PRESSURE HAS PUSHED A COLD FRONT AND
   RELATIVELY DRY AIRMASS THROUGH THE NORTHERN INTERIOR. SOUTH OF THE
   FRONTAL BOUNDARY SCATTERED SHOWERS AND THUNDERSTORMS WILL COVER MUCH
   OF THE CENTRAL AND EAST. THE ONLY EXCEPTION WILL BE IN THE SOUTHEAST
   WHERE DRY AIR CONTINUES TO LINGER ACROSS PORTIONS OF AL...GA...AND
   NORTHERN FL.
   
   ...CRITICAL FIRE WEATHER AREA - ...NERN CA/NWRN NV......
   
   PRIMARY CONDITIONS: LOW RH AND WINDY
   
   SURFACE WINDS WILL INCREASE TODAY BECOMING SOUTHWEST AT 15 TO 25 MPH
   DURING THE AFTERNOON. WARM TEMPERATURES RESULT IN MINIMUM RH VALUES
   OF 10 TO 15 PERCENT AND A PERIOD OF CRITICAL FIRE WEATHER
   CONDITIONS.
   
   NEAR CRITICAL FIRE WEATHER CONDITIONS WILL EXTEND EASTWARD FROM THE
   OUTLOOK AREA THROUGH THE GREAT BASIN...WITH MINIMUM RH IN THE TEENS
   AND SOUTHWEST WINDS AROUND 15 MPH.
   
   ...CNTRL/ERN MT...
   AS THE SURFACE COLD FRONT APPROACHES CENTRAL MT THIS AFTERNOON...THE
   POTENTIAL OF DRY THUNDERSTORMS INCREASES OVER PORTIONS OF CENTRAL
   AND EASTERN MT EXTENDING SOUTHWARD INTO EASTERN ID. PRECIPITABLE
   WATER VALUES ARE EXPECTED TO BE AROUND 0.75 INCH...BUT RELATIVELY
   LOW RH NEAR THE SURFACE /15 TO 20 PERCENT/ AND INCREASING CELL
   SPEEDS AROUND 25 MPH WILL RESULT IN ISOLATED DRY THUNDERSTORMS
   DURING THE AFTERNOON.
   
   ...SRN AL/SRN GA/NRN FL...
   DRY AIR CONTINUES TO LINGER ACROSS THE INTERIOR SOUTH WITH MINIMUM
   RH AGAIN EXPECTED TO DIP TO ABOUT 30 PERCENT. TEMPERATURES WILL
   CLIMB INTO THE LOWER 90S BUT WINDS WILL REMAIN LIGHT /5 TO 10 MPH/
   AND FROM THE EAST.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0414 AM CDT MON JUL 10 2006
   
   VALID 111200Z - 121200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR ...NERN CA/NWRN NV......
   
   ...SYNOPSIS...
   WESTERLY FLOW CONTINUES TO INCREASE ACROSS THE WESTERN U.S. AS
   ANOTHER SHORTWAVE TROUGH MOVES THROUGH THE PACIFIC NORTHWEST. DRIER
   PACIFIC AIR CONTINUES TO SPREAD EASTWARD...WITH THE THREAT OF
   CRITICAL OR NEAR CRITICAL FIRE WEATHER CONDITIONS EXTENDING EASTWARD
   INTO THE GREAT BASIN AND EASTERN ID.
   
   FARTHER EAST...THE DEVELOPMENT OF A LEE TROUGH IN THE TX/OK
   PANHANDLES BRINGS BREEZY SOUTH WINDS OF 15 TO 25 MPH OVER THE
   SOUTHERN PLAINS. SURFACE DEWPOINTS SHOULD REMAIN ABOVE 60 DEGREES
   /MINIMUM RH 25 TO 30 PERCENT/ THEREBY MINIMIZING THE LARGE SCALE
   FIRE WEATHER THREAT. 
   
   AS A SURFACE LOW AND COLD FRONT APPROACH THE GREAT LAKES
   REGION...SCATTERED SHOWERS AND THUNDERSTORMS AGAIN OCCUR OVER MUCH
   OF THE CENTRAL AND EAST. THE AIRMASS OVER THE INTERIOR SOUTH BEGINS
   TO MOISTEN ON TUESDAY...AND ALTHOUGH THE CHANCE OF THUNDERSTORMS
   REMAINS LOW OVER AL/GA/NRN FL...MINIMUM RH VALUES SHOULD REMAIN AT
   OR ABOVE 35 PERCENT.
   
   ...CRITICAL FIRE WEATHER AREA - ...NERN CA/NWRN NV......
   
   PRIMARY CONDITIONS: LOW RH AND WINDY
   
   ANOTHER WINDY AND DRY DAY OCCURS OVER NORTHEAST CA AND NORTHWEST NV.
   THE PASSAGE OF ANOTHER IN A SERIES OF DRY TROUGHS LEADS TO AFTERNOON
   SURFACE WINDS OF 20 TO 30 MPH AND MINIMUM RH AROUND 10 PERCENT.
   
   ...GREAT BASIN/CNTRL AND ERN ID...
   NEAR CRITICAL FIRE WEATHER CONDITIONS DEVELOP OVER THE GREAT BASIN
   EAST OF THE CRITICAL AREA...AND ALSO OVER CENTRAL AND EASTERN ID. AS
   THE WESTERN TROUGH CONTINUES TO DEEPEN...SOUTHWEST WINDS INCREASE TO
   15 TO 25 MPH IN THE GREAT BASIN...AND 20 TO 30 MPH OVER PORTIONS OF
   IDAHO. WARM TEMPERATURES PRODUCE MINIMUM RH IN THE MID TEENS IN THE
   GREAT BASIN...AND IN THE UPPER TEENS OVER EASTERN ID. 
   
   ...ERN UT/SRN AZ...
   LINGERING MOISTURE MAY RESULT IN CONDITIONS FAVORABLE FOR A FEW DRY
   THUNDERSTORMS OVER THE HIGHER TERRAIN OF SOUTHERN AZ AND EASTERN UT
   TUESDAY AFTERNOON.
