   ...SYNOPSIS...
   ANOTHER UPPER LEVEL TROUGH MOVES FROM THE PACIFIC NORTHWEST COAST TO
   INTERIOR OREGON/WASHINGTON TODAY...BRINGING BREEZY AND GENERALLY DRY
   CONDITIONS FROM THE GREAT BASIN TO CENTRAL IDAHO.  FARTHER
   NORTH...SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED FROM
   CENTRAL IDAHO THROUGH THE NORTHERN ROCKIES.
   
   AN UPPER LOW OVER NEW ENGLAND CONTINUES ITS SLOW EASTWARD
   DRIFT...WITH NORTHWEST FLOW ALOFT OVER THE CENTER OF THE NATION. 
   SURFACE HIGH PRESSURE OVER THE UPPER MIDWEST HAS PUSHED A
   COOLER/DRIER AIRMASS AS FAR SOUTH AS THE GULF OF MEXICO AND CENTRAL
   FLORIDA.
   
   ...CRITICAL FIRE WEATHER AREA 1 - CNTRL/SERN ID...
   
   PRIMARY CONDITIONS: LOW RH AND GUSTY WINDS
   
   ANOTHER IN A SERIES OF SHORTWAVE TROUGHS APPROACHES THE COLUMBIA
   BASIN BY LATE THIS AFTERNOON...CONTINUING THE RATHER STRONG
   SOUTHWEST FLOW ALOFT OVER THE AREA.  GUSTY WINDS WILL AGAIN MIX TO
   THE SURFACE THIS AFTERNOON...PRODUCING WINDS OF 15 TO 25 MPH AND
   GUSTS TO 30 MPH.  MINIMUM RH VALUES IN THE 10 TO 15 PERCENT RANGE
   LEAD TO CRITICAL FIRE WEATHER CONDITIONS FROM THIS AFTERNOON THROUGH
   THE EARLY EVENING.
   
   ADDITIONALLY...CONDITIONS OVER CENTRAL AND FAR EASTERN IDAHO CAN
   SUPPORT ISOLATED DRY THUNDERSTORMS WITH LOCALIZED STRONG/GUSTY WINDS
   LATER TODAY.  FARTHER NORTH AND EAST...MOISTURE AND INSTABILITY ARE
   SUFFICIENT FOR SCATTERED THUNDERSTORMS WITH WETTING RAIN.
   
   ...ECNTL NV/NWRN UT...
   A DEEP MIXED LAYER RESULTS IN AFTERNOON SURFACE WINDS OF 15 TO 20
   MPH AND MINIMUM RH VALUES OF 10 TO 15 PERCENT OVER PORTIONS OF THE
   EASTERN GREAT BASIN TODAY.  FIRE DANGER RATINGS REMAIN IN THE VERY
   HIGH TO EXTREME RANGE...RESULTING IN NEAR CRITICAL FIRE WEATHER
   CONDITIONS THIS AFTERNOON AND EARLY EVENING.
   
   ...MS/AL/GA...
   MINIMUM RH VALUES FALL INTO THE UPPER 20 TO MIDDLE 30 PERCENT RANGE
   DURING THE AFTERNOON...AS NORTH WINDS OF 10 TO 15 MPH CONTINUE TO
   ADVECT A RELATIVELY DRY AIRMASS INTO THE REGION.  LOCALIZED NEAR
   CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED FOR A BRIEF PERIOD
   THIS AFTERNOON AS WINDS GUST TO 20 MPH.  HOWEVER...THE COMBINATION
   OF KEETCH-BYRAM DROUGHT INDICES LESS THAN 500 AND THE LACK OF
   WIDESPREAD CRITICAL CONDITIONS PRECLUDES ISSUING A FIRE WEATHER
   CRITICAL AREA.
