...AVIATION DISCUSSION...
COMPLICATED AVIATION FORECAST UNFOLDING FOR THIS EVENING...AS SVR
TSRA CONTINUE TO DEVELOP ACROSS WEST CENTRAL TEXAS. WILL NOT MAKE
ANY MAJOR CHANGES TO CURRENT TAF PACKAGE...WITH STORMS POSSIBLY
AFFECTING BOTH DFW AND WACO AREA AIRPORTS AFTER 12/02Z. MAIN SEVERE
WEATHER THREATS THIS EVENING WILL BE LARGE HAIL AND STRONG
DOWNBURSTS WINDS. AWW PRODUCTS WILL BE ISSUED IF NECESSARY. WILL
DIMINISH TSRA CHANCES BETWEEN 12/06Z-12/10Z...WITH A RETURN TO
STRONGER SOUTH FLOW AND SCT DECK AROUND 5 KFT BY LATE MORNING.

65/DD

...PREVIOUS PUBLIC DISCUSSION...
TO CONFUSE THE AFTERNOON PACKAGE...18Z SOUNDING HAS STRENGTHENED THE
18Z CAP AT 850 MB...AND LOW AND MID LEVEL WINDS HAVE DROPPED TO 15
TO 20 KT.  CAPES AND INSTABILITIES REMAIN VERY HIGH...SO STILL THINK
STORMS WILL DEVELOP...BUT MAYBE NOT AS WIDESPREAD AS PREVIOUSLY
THOUGHT.  WILL LEAVE IN LOCALLY HEAVY RAIN AS STORM MOVEMENT WILL
NOT BE OVER 15-20 KTS DUE TO THESE WEAK WIND FIELDS.  BEST CHANCE OF
RAIN NOW LOOKS LIKE IT MAY BE THURSDAY NIGHT AND EARLY FRIDAY AS
STRONGER SHORTWAVE MOVES EASTWARD ACROSS SOUTHERN OKLAHOMA.   VERY
MOIST AND UNSTABLE AIRMASS WILL REMAIN ACROSS NORTH TEXAS WITH SFC
DEWPOINTS IN THE LOW TO MID 70S CONTINUING FOR THE NEXT SEVERAL
DAYS.
