.AVIATION...

...SQUALL LINE TO MOVE ACROSS KDFW TRACON 00-03Z...

AN AIRPORT WEATHER WARNING IS HIGHLY LIKELY THIS EVENING FOR
KDFW/KDAL AIRPORTS DUE TO STRONG WINDS AHEAD OF A SQUALL LINE.

SQUALL LINE AND OUTFLOW BOUNDARY NEARING RED RIVER VALLEY AT 23Z AND
WILL PROGRESS SOUTH ACROSS ALL OF NORTH TEXAS THROUGH 06Z. IT WILL
REACH THE NORTHERN KDFW TRACON SHORT OF 00Z...AND INTO
KDFW...KFTW...KDAL AIRPORTS AROUND 0030Z.  SQUALL GUSTS TO 45KTS ARE
EXPECTED FOLLOW BY +TSRA THROUGH 02Z.  THIS SQUALL LINE IS EXPECTED
TO MARCH THROUGH KACT AIRPORT 03-05Z.

POTENTIAL EXISTS FOR ANOTHER THUNDERSTORMS COMPLEX (MCS) TO MOVE OUT
THE TEXAS PANHANDLE OR HIGH PLAINS LATE TONIGHT AND MOVE ACROSS
NORTH TEXAS AIRPORTS DURING THE EARLY MORNING HOURS 11-16Z.  75

&&

.DISCUSSION...
239 PM.
BEST REASONING ATTM IS THE OUTFLOW BOUNDARY FROM THE STORMS MOVING
INTO CENTRAL OK WILL BE THE FOCUS FOR TONIGHTS STORMS IN NORTH
CENTRAL TEXAS. THAT OUTFLOW IS MOVING SOUTH-SOUTHEAST AT 30 TO 40
MPH INTO 70+ DEWPOINTS. SHOULD IT CONTINUE AT THAT SPEED IT WILL
MOVE TO THE RED RIVER AROUND 6 PM...METROPLEX AROUND 8 PM AND WACO
AROUND 10 BRINGING THUNDERSTORMS WITH IT. LARGE HAIL AND DAMAGING
WIND APPEARS TO BE THE PRIMARY THREAT WITH THESE STORMS. MORE
STORMS...CURRENTLY DEVELOPING IN COLORADO...WILL ALSO MOVE SE
OVERNIGHT BUT BELIEVE THE OUTFLOW BOUNDARY FROM THIS EVENING STORMS
WILL BE TO THE WEST OF THE FORECAST AREA KEEPING THE BULK OF THE
PRECIPITATION CONFINED MAINLY TO THE WESTERN HALF OF THE FORECAST
AREA THURSDAY MORNING. TEMPS WILL BE LOWER THURSDAY DUE TO HIGH
CLOUD COVER. MODELS BRING ANOTHER CLUSTER OF THUNDERSTORMS OVER
NORTH TEXAS FRIDAY AFTERNOON AND EVENING. HAVE ADDED SLIGHT CHANCE
POPS FOR NOW BUT WILL LIKELY BE INCREASED SHOULD ADDITIONAL MODEL
RUNS CONTINUE THE SAME TREND. FARTHER OUT...WEAK RIDGE SLIDES EAST
DURING THE WEEKEND CHANGING FLOW ALOFT FROM WNW TO W TO SW BY
TUESDAY WITH TEMPS RETURNING TO NORMAL. 82
