DISCUSSION
CURRENT OBSERVATIONS NEAR THE FIRE SHOW LIGHT (<10 MPH) WINDS,
GENERALLY FROM THE EAST/SOUTHEAST WITH RH VALUES RANGING BETWEEN
24-30%. WINDS SHOULD REMAIN FROM THE EAST, GENERALLY BETWEEN 6-12
MPH FOR THE NEXT FEW HOURS BEFORE TURNING MORE SOUTHWESTERLY BY
2100 MDT. HOWEVER, THERE IS ABOUT A 10-15% CHANCE OF A WEAK VIRGA
SHOWER/THUNDERSTORM NOW THROUGH 2100 THAT COULD PRODUCE LIGHTNING
IN THE VICINITY AND GUSTY VARIABLE WINDS OF 20-30 MPH. OVERNIGHT
HUMIDITY RECOVERIES WILL BE UP TO 40%.
FOR TOMORROW, HOT AND RELATIVELY DRY CONDITIONS EXPECTED AGAIN,
WITH MINIMUM RH DOWN TO 13-16%. WINDS SHOULD GENERALLY BE FROM THE
WEST WITH GUSTS UP TO 20 MPH POSSIBLE THROUGHOUT THE AFTERNOON.
WEAK SHOWERS/THUNDERSTORMS POSSIBLE, MAINLY FROM 1500-1900 MDT
(10-15% CHANCE). LIGHTNING AND GUSTY OUTFLOW WINDS OF 30 MPH
EXPECTED WITH STRONGEST STORMS. WETTING RAIN IS UNLIKELY.
