FORECAST IS BASED ON IGNITION TIME OF 2000 CDT ON APRIL 20.

..RED FLAG WARNING IN EFFECT UNTIL 8 PM CDT THIS EVENING
DISCUSSION
WE DO HAVE A DRY AIRMASS IN PLACE, SO RH RECOVERY TONIGHT IS
GOING TO BE SOMEWHAT LIMITED BY THAT. THE FORECAST BELOW KEEPS MIN
RH GOING TO THE MEAN VALUE OF MOST MODELS FOR JUST A COUPLE HOURS
AROUND SUNRISE (AROUND 85%). I THINK RH WILL BE AT LEAST SOMEWHAT
QUICK TO DROP IN THE MID-MORNING, PROBABLY RIGHT AROUND THE START
TIME OF YOUR BURN. I WOULD ERR ON THE SIDE OF THINGS BEING A
LITTLE BIT DRIER THAN THIS FORECAST, IF THERE WERE TO BE ANY
CHANGES, BUT THE VALUES I HAVE ARE WHAT I'M CURRENTLY EXPECTING.
AS FOR WINDS, WE WILL HAVE THE HIGH PRESSURE CENTER MOVING AT US
THROUGH THE DAY. WITH THAT, I HAVE HIGHER CONFIDENCE THAT SPEEDS
IN GENERAL WON'T BE VERY STRONG. I'M NOT EXPECTING GUSTS TO BE TOO
FAST EITHER...HOVERING AROUND OR JUST ABOVE 10 MPH AT MOST. WITH
THE HIGH PRESSURE MOVING OUR WAY AND BEING CLOSE BY, I THINK SOME
VARIABILITY IN DIRECTION CAN BE EXPECTED. WIND DIRECTION MAY BE
SLIGHTLY MORE CONSISTENT IN THE MORNING VERSUS AFTERNOON, BUT
THERE COULD BE SOME ERRATIC DIRECTION CHANGES THROUGH THE DAY WITH
THE LIGHT WINDS THAT WILL, IN GENERAL, BE OUT OF THE NORTH.
ALL-IN-ALL, EXPECT A PRETTY WARM AND DRY TUESDAY. INVERSION HEIGHT
WILL INCREASE INTO THE AFTERNOON, BUT THERE WILL PROBABLY BE AN
INVERSION IN PLACE THROUGH THE DAY WITH MIXING HEIGHT GETTING TO
AROUND 4 THOUSAND FEET.
