IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...GENERALLY WEAK WESTERLY FLOW ALOFT PROGGED TO CONTINUE
ACROSS THE AREA AS UPPER LEVEL RIDGING BUILDS ACROSS THE STATE THROUGH
THE DAY WEDNESDAY. INITIALLY...DRIER AIR FROM ALOFT WILL HELP MIX OUT
LOW LEVEL MOISTURE ACROSS THE BURN SITE TODAY (WILLIS CREEK RAWS TO THE
SOUTH AND WEST OF THE BURN SITE HAS A CURRENT DEW POINT OF 27F) AND
SHOULD LIMIT DEEP MOIST CONVECTION ACROSS THE AREA THIS AFTERNOON...THOUGH
STILL CANT RULE OUT A FEW HIGH BASED STORMS THROUGH THE EARLY EVENING.
WARM AIR ALOFT LOOKS TO KEEP OVERNIGHT LOWS ON THE MILD SIDE AND LOOKS TO
LIMIT RH RECOVERY OVERNIGHT. MID AND UPPER LEVEL MOISTURE SLOWLY INCREASES
ACROSS THE AREA WEDNESDAY AND ALONG WITH A WEAK FRONT MOVING ACROSS THE
EASTERN PLAINS AND I-25 CORRIDOR WEDNESDAY AFTERNOON...WILL ALLOW FOR
BETTER CHANCES OF WETTING RAINS ACROSS THE BURN SITE LATE WEDNESDAY
AFTERNOON AND EVENING.
