   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0324 AM CDT MON JUN 11 2007
   
   VALID 111200Z - 121200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SRN GREAT BASIN NEWD TOWARDS THE
   CNTRL ROCKIES...
   
   ...SYNOPSIS...
   A MID-LEVEL SHORT WAVE TROUGH OVER THE NRN GREAT BASIN WILL LIFT
   NEWD REACHING SASKATCHEWAN BY EARLY TUE. ATTENDANT MODERATELY STRONG
   SWLY FLOW WILL SHIFT FROM THE GREAT BASIN/NRN ROCKIES NEWD ONTO THE
   NRN HIGH PLAINS AND S-CNTRL CANADIAN PRAIRIES. DOWNSTREAM MID/UPPER
   RIDGING WILL EXPAND NWD FROM THE SRN PLAINS TO THE WRN GREAT LAKES.
   IN THE SOUTHWEST...A CLOSED UPPER LOW OVER NRN BAJA CA WILL
   GRADUALLY TRANSLATE NEWD INTO AZ TONIGHT.
   
   ...CRITICAL FIRE WEATHER AREA - SRN GREAT BASIN NEWD TOWARDS THE
   CNTRL ROCKIES...
   
   PRIMARY CONDITIONS: LOW RH / GUSTY WINDS / HIGH TO EXTREME FIRE
   DANGER
   
   A WARM AND VERY DRY AIR MASS REMAINS SANDWICHED BETWEEN A COLD FRONT
   ASSOCIATED WITH THE NRN GREAT BASIN SHORT WAVE TROUGH AND INCREASING
   SUB-TROPICAL MOISTURE ASSOCIATED WITH THE NRN BAJA CA UPPER LOW. AS
   THE NRN GREAT BASIN TROUGH LIFTS NEWD...THE FRONTAL BOUNDARY WILL
   STALL. ALTHOUGH UPPER-LEVEL CLOUD COVER WILL LIMIT HEATING
   SOMEWHAT...TEMPERATURES WILL LIKELY REACH THE 80S/90S ACROSS MOST
   LOWER ELEVATION LOCALES. THIS SHOULD RESULT IN WIDESPREAD MIN RH
   VALUES OF 6 TO 12 PERCENT. ALTHOUGH SWLY MID-LEVEL FLOW IS EXPECTED
   TO GRADUALLY WEAKEN WITH THE APPROACH OF THE NRN BAJA CA LOW...VERY
   STEEP LOW-LEVEL LAPSE RATES AND DEEP MIXING SHOULD PRODUCE FREQUENT
   WIND GUSTS IN EXCESS OF 25 MPH WITH POCKETS OF SUSTAINED WINDS
   AROUND 20 MPH.
   
   ...ERN MS/AL/WRN FL PANHANDLE...
   HOT/DRY WEATHER WITH LIGHT NELY WINDS PREVAILED ON SUNDAY ACROSS THE
   AREA. LITTLE OVERALL CHANGE IN THE SYNOPTIC PATTERN WILL YIELD
   SIMILAR CONDITIONS TODAY...ALBEIT A BIT FARTHER WWD. A SUBTLE
   SURFACE LOW INVOF TLH SHOULD REMAIN NEARLY STATIONARY THROUGH THE
   PERIOD. WEAK NELY FLOW TO THE N/NW OF THE LOW SHOULD RESULT IN A
   SLOW INCREASE IN LOW-LEVEL MOISTURE FROM E TO W. HOWEVER...WITH
   TEMPERATURES REBOUNDING INTO THE 90S...AFTERNOON RH VALUES OF 20 TO
   30 PERCENT WILL REMAIN LIKELY. THE MITIGATING FACTOR TO A CRITICAL
   THREAT WILL BE THE CONTINUED LIGHT WINDS /AOB 10 MPH/.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0407 AM CDT MON JUN 11 2007
   
   VALID 121200Z - 131200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A HIGHLY AMPLIFIED UPPER-LEVEL PATTERN WILL CONTINUE ACROSS THE
   CONUS...FEATURING AN EXPANSIVE RIDGE OVER THE CNTRL STATES WITH
   TROUGHS ACROSS THE WEST AND EAST. A CLOSED UPPER LOW EXPECTED TO BE
   OVER AZ EARLY TUE SHOULD GRADUALLY TRACK EWD ACROSS THE SRN ROCKIES.
   LOW/MID-LEVEL FLOW WILL BE SUBSTANTIALLY WEAKER IN ITS WAKE ACROSS
   THE GREAT BASIN/DESERT SOUTHWEST. IN THE EAST...A MID-LEVEL SHORT
   WAVE TROUGH SHOULD DIVE SWD FROM THE OH RIVER VALLEY INTO THE
   SOUTHEAST. THIS SHOULD MAINTAIN DRY NLY FLOW ACROSS THE TN VALLEY
   TUE AFTERNOON.
   
   ...NERN MS/NRN AL...
   DRY NLY WINDS SHOULD INCREASE SLIGHTLY COMPARED TO DAY 1 AS A SHORT
   WAVE TROUGH ENHANCES LOW/MID-LEVEL FLOW ACROSS THE REGION. SUSTAINED
   WIND SPEEDS SHOULD ONLY REACH 10 TO 15 MPH. TEMPERATURES MAY BE A
   FEW DEGREES COOLER /IN THE UPPER 80S/...BUT RH VALUES SHOULD STILL
   APPROACH 25 PERCENT.
