Area forecast discussion, Apr 29, 4:08 PM CDT, 2 hours 21 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FORT WORTH TX 408 PM CDT MON APR 29 2002 WARM FRONT LIES PRETTY MUCH ALONG THE RED RIVER TODAY. OPPRESSIVE HEAT AND HUMIDITY SURGED ACROSS THE ENTIRE AREA TODAY. NUMEROUS CU HAVE FORMED ALONG THE WARM FRONT AND ALONG A BOUNDARY EXTENDING WEST TOWARDS ABILENE. A FEW STORMS MAY SPRING UP WEST...WITH AROUND 100 DEGREE TEMPERATURES IN SAN ANGELO. FOR OUR NORTHEASTERN COUNTIES...WE HAVE LEFT IN A CHANCE OF THUNDERSTORMS OVERNIGHT WITH THE WARM FRONT NOT TOO FAR AWAY. FURTHER SOUTH...I HAVE PUT IN A SLIGHT CHANCE FOR THE METROPLEX. HOWEVER...THE 18Z FWD SOUNDING STILL INDICATED A FORMIDABLE CAP. NEVERTHELESS...A FEW STORMS MAY MANAGE TO POP THROUGH DURING MAXIMUM HEATING IN THE NEXT FEW HOURS. OUR WINDS ALOFT HAVE WEAKENED CONSIDERABLE SINCE EARLIER...SO ANY STORMS THAT FORM WOULD LIKELY BE A HAIL OR HIGH WIND THREAT...RATHER THAN TORNADIC. TUESDAY AND WEDNESDAY LOOK AS IF THE HEAT WILL BE HANGING ON. HOWEVER...WITHOUT A BOUNDARY NEARBY...WE ARE NOT EXPECTING PRECIPITATION. THE EXCEPTION IS THE EXTREME NORTHEAST TUESDAY NIGHT...WHERE A FEW SHOWERS OR STORMS COULD SPRING UP WITH ENERGY MOVING ACROSS OKLAHOMA ATOP THE RIDGE ALOFT. THURSDAY WILL BRING A DRAMATIC COOLDOWN AS A DECENT FRONT FOR THIS TIME OF YEAR DIVES SOUTH INTO NORTH TEXAS. HIGHS WILL DROP SOME 15 OR 20 DEGREES. AFTER THURSDAY...WE WILL WARM UP SLOWLY UNTIL A WARM FRONT DRIVES NORTH OF THE REGION BY SUNDAY. MONDAY LOOKS VERY WARM AND DRY AT THIS TIME. ENJOY THE BRIEF COOLDOWN THURSDAY FCSTID = 30 DFW 72 92 72 91 / 20 0 0 0 ACT 72 94 73 92 / 0 0 0 0 .FWD...NONE.

THE MAIN THUNDERSTORM THREATS WILL BE LARGE HAIL....DAMAGING WINDS ...AND ISOLATED TORNADOES. ANY TORNADOES THAT OCCUR MOST LIKELY WILL BE NEAR THE RED RIVER. SPOTTER ACTIVATION WILL BE NEEDED WITHIN THE SLIGHT RISK AREA...MOST LIKELY AFTER 500 PM. ONCE AGAIN...HUMID AND VERY UNSTABLE AIR IS SITUATED ACROSS NORTH TEXAS THIS AFTERNOON. THE COMBINATION OF STRONG WINDS ALOFT...HIGH INSTABILITIES...A STATIONARY FRONT...AND RELATIVELY LOW CLOUD BASES NEAR THE RED RIVER SUGGESTS THAT A SUPERCELL TORNADO OR TWO COULD OCCUR IN THAT AREA. THE MITIGATING FACTOR FOR MOST OF THE AREA IS A STRONG CAPPING INVERSION....ABOUT ONE MILE ABOVE THE SURFACE. THE STRONG CAP SUGGESTS THERE IS LITTLE CHANCE OF STORMS SOUTH OF INTERSTATE 20 TODAY. CLOSER TO THE RED RIVER...THE CAP IS WEAKER...AND A FEW SEVERE STORMS ARE POSSIBLE. A SPECIAL UPPER AIR BALLON SOUNDING IS BEING LAUNCHED FROM FORT WORTH...AND THE DATA FROM THE SOUNDING WILL BE USED TO UPDATE THE HAZARDOUS WEATHER OUTLOOK ABOUT 300 PM.

KAUFMAN...AND CANTON. THE MAIN THREATS WILL BE LARGE HAIL AND DAMAGING WINDS. THE TORNADO THREAT HAS BECOME QUITE LOW...BECAUSE OF LIGHT LOW LEVEL WINDS IN THE THREAT AREA.

AT 300 PM...THE STATIONARY FRONT WAS SITUATED NEAR A SHERMAN TO COOPER LINE. THE THREAT OF DAMAGING SUPERCELL STORMS MAY BE GREATEST NEAR AND IMMEDIATELY NORTH OF THIS FRONT THROUGH MID-EVENING.
