   ...CRITICAL FIRE WEATHER AREA FOR SOUTHEAST IDAHO...
   ...CRITICAL FIRE WEATHER AREA FOR GREAT BASIN...
   
   ...SYNOPSIS...
   A HIGH AMPLITUDE PATTERN CONTINUES WITH STRONG UPPER RIDGING OVER
   THE CENTRAL UNITED STATES AND TROUGHING NEAR THE COASTS.  AN UPPER
   TROUGH OFF THE PACIFIC NORTHWEST COAST KEEPS SOUTHWEST FLOW ALOFT
   OVER THE WEST CREATING SOME FIRE WEATHER CONCERNS FROM THE GREAT
   BASIN TO THE NORTHERN ROCKIES. STRONG SURFACE HIGH PRESSURE OVER
   THE NORTHERN PLAINS MINIMIZES LARGE SCALE FIRE WEATHER CONCERNS IN
   THE CENTRAL AND EASTERN STATES.
   
   ...CRITICAL FIRE WEATHER AREA 1 - SERN ID...
   
   PRIMARY CONDITIONS: LOW RH AND GUSTY WINDS
   
   A SHORTWAVE TROUGH EJECTING FROM THE AFOREMENTIONED PACIFIC
   NORTHWEST LOW APPROACHES IDAHO AROUND MID AFTERNOON.  WINDS AT THE
   SURFACE AND ALOFT INCREASE AS THE SYSTEM APPROACHES...WITH SURFACE
   WINDS OF 15 TO 25 MPH AND GUSTS TO 30 MPH THIS AFTERNOON.  THE
   AIRMASS REMAINS GENERALLY DRY AND MINIMUM RH VALUES FALL TO 10 TO 15
   PERCENT.  NORTHERN SECTIONS OF THE CRITICAL AREA ARE ALSO SUSEPTIBLE
   TO ISOLATED DRY THUNDERSTORMS DURING THE AFTERNOON.
   
   ...CRITICAL FIRE WEATHER AREA 2 - ERN NV...
   
   PRIMARY CONDITIONS: LOW RH AND GUSTY WINDS
   
   CONDITIONS THIS AFTERNOON AND EARLY EVENING ARE AGAIN FAVORABLE FOR
   MINIMUM RH VALUES TO FALL TO AROUND 10 PERCENT AS SURFACE WINDS
   INCREASE TO 15 TO 25 MPH.  ALTHOUGH WEATHER CONDITIONS ARE
   BORDERLINE CRITICAL...PREDICTED FIRE DANGER CLASS RATINGS OF VERY
   HIGH TO EXTREME WARRANT THE ISSUANCE OF A CRITICAL AREA.
