.DISCUSSION...

THE DRY EASTERLY FLOW WILL CONTINUE THROUGH TOMORROW AND HELP TO
SUPPRESS THE THREAT OF SHOWER AND STORMS. THERE ARE LOW CHANCES
OF PRECIPITATION IN THE FORECAST FOR TUESDAY, BUT THE CHANCES ARE
TRENDING DOWN AND THE SUBSEQUENT SHIFTS MAY BE ABLE TO CUT OUT
PRECIPITATION ALL TOGETHER. I FORECASTED A MINIMUM RH NEAR 50
PERCENT FOR TOMORROW AT THE PROPOSED BURN LOCATION, BUT THIS COULD
BE 5 TO 15 PERCENT LOWER DEPENDING ON THE MIXING POTENTIAL AND IF
THE LATEST MODEL RUNS ARE NOT HANDLING DEW POINTS WELL. THE LATEST
MODEL INDICATE SIGNIFICANTLY HIGHER DEW POINTS TOMORROW THAN WHAT
THEY WERE TODAY, AND WE WILL NEED TO SEE WHAT THE HIGH RESOLUTION
MODELS PROVIDE US TONIGHT. THE EASTERLY WINDS TOMORROW WILL LIKELY
BE AROUND 10 MPH.
