   RESPONSE TO ERN PACIFIC TROUGH. IT APPEARS THAT INITIAL JET STREAK
   WILL MOVE SLOWLY EWD ACROSS NRN/CNTRL CA AND OREGON TODAY WITH
   MODERATELY STRONG MID LEVEL FLOW INCREASING ACROSS THE SOUTHWEST.
   CONTINUED ABOVE NORMAL TEMPERATURES AND VERY LOW HUMIDITY COMBINED
   WITH THE INCREASING WINDS WILL CONTRIBUTE TO A CRITICAL FIRE WEATHER

   WILL BE INCREASING ACROSS THE SRN PLAINS INVOF LEE TROUGH.

   15-20 MPH WITH HIGHER GUSTS. ADDITIONALLY HIGH TEMPS WILL RISE INTO
   THE 90S/100S AS MINIMUM RH VALUES FALL BELOW 10-15 PERCENT. RECENT

   VERY HIGH BASED TSTMS ARE POSSIBLE TODAY WITH THE POTENTIAL FOR DRY
   LIGHTNING STRIKES DUE TO A VERY DRY BOUNDARY LAYER. MID LEVEL WINDS
   ARE FORECAST TO BE RELATIVELY WEAK. HOWEVER...GUSTY OUTFLOW WINDS
   WILL ACCOMPANY STORMS. MINIMUM RH VALUES WILL FALL BELOW 15 PERCENT.

   ...CRITICAL FIRE WEATHER AREA FOR SRN AND CNTRL NV/UT/NW AZ...
   
   ...SYNOPSIS...
   WRN RIDGE AXIS WILL BEGIN TO SHIFT EWD ON SATURDAY WHILE NEXT
   SHORTWAVE TROUGH DIVES SEWD ACROSS THE GREAT LAKES. MID LEVEL WINDS
   ARE FORECAST TO REMAIN STRONG ACROSS THE GREAT BASIN...WITH WINDS
   INCREASING ACROSS UT IN ADVANCE OF WEST COAST STORM SYSTEM. AT THE
   SFC...LEE TROUGH WILL FORM ACROSS THE SRN PLAINS WITH A STATIONARY

   ...CRITICAL FIRE WEATHER AREA 1 - SRN AND CNTRL NV/UT/NW AZ...
   
   PRIMARY CONDITIONS: STRONG S/SW WINDS/LOW RH VALUES BELOW 15
   PERCENT/DRY FUELS
   
   SFC WINDS WILL INCREASE TO 15-25 MPH DURING THE DAY WITH HIGHER
   GUSTS POSSIBLE ACROSS NW AZ/SRN NV AND UT. STEEP LOW LEVEL LAPSE
   RATES WILL ALLOW SOME OF THE HIGHER MOMENTUM AIR TO BE MIXED TO THE
   SFC. IN ADDITION RH VALUES BELOW 15 PERCENT ARE LIKELY ACROSS
   PORTIONS OF THE CRITICAL AREA WITH TEMP/DEWPOINT SPREADS IN EXCESS
   OF 50-60 DEGREES.
   
   ...SW TX...
   SFC WINDS ON SATURDAY ARE EXPECTED TO BE STRONGER THAN FRIDAY...WITH
   CONTINUED LOW HUMIDITY VALUES. PRESSURE GRADIENT WILL STRENGTHEN IN
   RESPONSE TO DEEPENING LEE TROUGH. BOUNDARY LAYER DEWPOINTS WILL NOT
   HAVE RECOVERED AS RETURN FLOW FROM GULF IS MODIFIED CP IN ORIGIN.
   THEREFORE...MARGINALLY CRITICAL FIRE CONDITIONS ARE POSSIBLE DUE TO
   THE RELATIVELY DRY AIRMASS AND INCREASED WIND.
