DISCUSSION
HI-RES GUIDANCE IS STARTING TO COME INTO PLAY FOR
TUESDAY, AND SHOW SOME SHOWERS/STORMS MOVING INTO THE VICINITY OF
THE BURN LOCATION BY 1400-1500. WITH SMOKE DISPERSAL CONDITIONS
BECOMING FAIR BY 1100, THIS MAY ALLOW FOR A FEW HOUR WINDOW TO
BURN. STILL NOT EXPECTING HEAVY RAINFALL, BUT COULD SEE A FEW
HUNDREDTHS TO AROUND A TENTH OF ON INCH IF A STORM MOVES OVERHEAD.
AFTERNOON RELATIVE HUMIDITY IS STILL EXPECTED TO DROP INTO THE
20-25% RANGE, WITH OVERNIGHT RECOVERIES REMAINING FAIR AT ABOUT
55-60%, WHICH WOULD ALLOW FOR SOME SLIGHT DRYING TO PERSIST
OVERNIGHT. THERE WILL BE ISOLATED CHANCES FOR AFTERNOON SHOWERS
ON WEDNESDAY AND THURSDAY, BUT A LACK IN UPPER-LEVEL FORCINGS
WILL KEEP LESS POTENTIAL THAN TUESDAY. RELATIVE HUMIDITY VALUES
ARE EXPECTED TO DROP INTO THE 20-25% RANGE EACH DAY, WITH
OVERNIGHT RECOVERIES REMAINING FAIR AS THEY ARE ONLY EXPECTED TO
INCREASE TO AROUND 60%.
