   ...SYNOPSIS...

   WINDS.
     
   ...ERN GREAT BASIN...
   WINDS ASSOCIATED WITH THE WEAKENING UPPER TROUGH WILL BE WEAKER
   THAN ON MONDAY...BUT STILL STRONG ENOUGH TO POSE A HAZARD GIVEN THE
   DRY AIR IN PLACE.  WINDS WILL INCREASE THROUGHOUT THE DAY AND BY
   AFTERNOON REACH SUSTAINED SPEEDS NEAR 15 MPH WITH HIGHER GUSTS. 
   HIGHER TERRAIN WILL EXPERIENCE SLIGHTLY STRONGER WINDS CLOSER TO 20
   MPH AND GUSTY.  RH VALUES WILL REMAIN LOW AT 10-15 PERCENT IN
   GENERAL.  THE ATMOSPHERE WILL BE MODERATELY UNSTABLE TODAY...WITH
   HAINES INDICES OF 4 TO 5.  
   
   ...CENTRAL / SRN CA...
   VERY DRY AIR WILL ARRIVE FROM THE SW TODAY AND COMBINE WITH HOT
   TEMPERATURES TO PRODUCE AN UNSTABLE ATMOSPHERE.  AS A RESULT FIRE
   DANGERS WILL REMAIN VERY HIGH.  LARGE SCALE WINDS WILL BE
   RELATIVELY LIGHT HOWEVER...AVERAGING 10-15 MPH MOST PLACES.

   ...NO LARGE-SCALE SIGNIFICANT FIRE WEATHER CONDITIONS EXPECTED...
     
   ...SYNOPSIS... 
   NWRN U.S. TROUGH WILL SLIDE SLOWLY EWD INTO MT BY THURSDAY MORNING. 
   THIS WILL ALLOW HOT DRY AIR TO RETURN NWD INTO CA.  AIRMASS WILL
   REMAIN VERY DRY AND INCREASINGLY UNSTABLE FROM WY SW THROUGH THE
   GREAT BASIN AND INTO CA.  WINDS THROUGH THIS REGION WILL CONTINUE
   TO DECREASE AS UPPER TROUGH WEAKENS.  LARGE AREA OF HIGH PRESSURE
   OVER THE ERN U.S. WILL MAKE FOR MUCH DRIER CONDITIONS WITH
   GENERALLY LIGHT WINDS.
     
   ...CA / GREAT BASIN / SRN ID / WRN WY...
   VERY DRY AIR WILL REMAIN OVER THE GREAT BASIN.  SWLY WINDS WILL
   CONTINUE TO FEED THIS AIR INTO WY AS WELL...WHILE HOT DRY AIR MAKES
   A RETURN TO NRN CA.  CONDITIONS WILL LIKELY BE MORE UNSTABLE WED
   COMPARED TO TUE...WITH HAINES INDICES REACHING THE HIGH (6)
   CATEGORY IN PLACES...FROM SOUTH CENTRAL CA NEWD THROUGH
   NV...UT...AND WRN WY.  AFTERNOON SWLY BREEZES OF 10-15 MPH WITH
   HIGHER GUSTS CAN BE EXPECTED...WHILE MIN RH DROPS BELOW 10 PERCENT
   IN SPOTS.
     
   ...VA / CAROLINAS / GA...
   THE CANADIAN HIGH PRESSURE WILL MEAN LOW RH FOR THIS REGION.  MIN
   RH VALUES NEAR 30 PERCENT ARE EXPECTED...WITH LOCALLY LOWER VALUES. 
   LIGHT WINDS AND SOME RECENT PRECIPITATION WILL MITIGATE FIRE
   THREAT...ALTHOUGH EXCEPTIONAL DROUGHT CONDITIONS AND GOOD DAYTIME
   DRYING CONDITIONS SUGGEST AN INCREASING THREAT WITH TIME.
