.DISCUSSION...THE COLD FRONT IS THROUGH ELM CREEK WITH NNW WINDS OF
20 TO 25 MPH AT THE INTERSTATE INTERCHANGE. THE WIND SPEED SHOULD
SETTLE DOWN A BIT...BUT STILL REMAIN FAIRLY STRONG FROM THE NORTH
THE REST OF THE DAY. THE COLD AIR NEAR THE SURFACE IS UNDERCUTTING
WARM AIR ALOFT...SO A SHARP INVERSION HAS ALREADY SET UP AND WILL
IMPACT MIXING HEIGHTS. AT IGNITION TIME...MIXING HEIGHTS WILL BE
AROUND 1500 TO 1800 FT AGL. AT 1 PM...LOOK FOR A MIXING HEIGHT
OF 2200 TO 2400...WITH MAXIMUM MIXING HEIGHT BETWEEN 3000 AND 3500
FT AGL IN THE MID/LATE AFTERNOON. PRETTY DRY AIR IS COMING IN QUICK
BEHIND THE FRONT...WITH DEWPOINTS NEAR 40 DEGREES POSSIBLY BY LATE
MORNING. CURRENT FORECAST OF LOW RH AROUND 35 PERCENT /MAYBE A TOUCH
LESS AT TIMES/ SHOULD HOLD REASONABLY WELL...GIVEN TEMPERATURES WILL
BE MUCH COOLER TODAY. THERE REALLY IS NO REASONABLE RISK FOR A WETTING
RAIN DURING THE DAY TODAY.
