Area forecast discussion, May 6, 6:20 PM CDT, 20 minutes before
AREA FORECAST DISCUSSION...AVIATION UPDATE NATIONAL WEATHER SERVICE FORT WORTH TX 620 PM CDT TUE MAY 6 2003 .00Z AVIATION DISCUSSION 620 PM CDT... CONVECTION BACK BUILT QUICKLY SOUTH OF THE RED RIVER. MEAN CELL MOTION TO THE NE WILL LIKELY KEEP WORST WELL TO THE NORTH OF METRO APTS...DESPITE GRADUAL EASTWARD PROGRESSION OF THE LINE OF STORMS AS A WHOLE. CB SHOULD SUFFICE FOR EARLY EVENING. LOW VSB TO CONTINUE TO THE EAST OF THE DRYLINE...PREVAILING 4SM LIKELY OVERNIGHT...WITH SOME BR NEAR 2SM. MVFR CIGS LIKELY AGAIN TONIGHT...WITH TEMPO IFR. SCATTERING NEAR MIDDAY. 25 .UPDATE FOR SEVERE THUNDERSTORM WATCH 540 PM CDT... HAVE ISSUED A MINOR UPDATE TO INCLUDE SEVERE THUNDERSTORM WATCH 274...VALID UNTIL 10 AM FOR THE NORTHERN HALF OF NORTH TEXAS. WILL UP POPS IN ALL ZONES SLIGHTLY...HOWEVER...ONLY SCATTERED COVERAGE IS EXPECTED SO NO POPS WILL BE HIGHER THAN 30 PERCENT. NO OTHER CHANGES AT THIS TIME. .AFTERNOON PUBLIC DISCUSSION 406 PM CDT... SHOWERS AND STORMS TO THE SOUTHEAST ARE FIZZLING OR MOVING OUT AT THIS HOUR...AS SHORT WAVE ENERGY EXITS TO THE NORTH OF THE REGION AND THE ATMOSPHERE STABILIZES IN THE WAKE OF EARLIER CONVECTION. ELSEWHERE...NUMEROUS OUTFLOW BOUNDARIES ARE SPEWING FROM THE SOUTHERN CONVECTION ACROSS THE REGION...WHILE SOME DRYLINE CONVERGENCE HAS BUBBLED CUMULUS OVER FAR NORTHWESTERN AREAS. PRECIPITATION COVERAGE LOOKS POOR THIS EVENING. THE 18Z SOUNDING NEEDS MID 90S TO OVERCOME THE CAP...AND WE ARE NOWHERE CLOSE EXCEPT NORTHWEST. WILL LEAVE ISOLATED POPS IN THE NORTHWEST AND NORTH THIS EVENING IF ANY DRYLINE/OUTFLOW BOUNDARY ACTIVITY GOES AND ADVECTS EAST. ANYTHING THAT FORMS COULD BE SEVERE WITH THE INSTABILITY...SO HAVE MENTIONED IN ZONES. OVERNIGHT...I WILL PUT IN SLIGHT CHANCE POPS FOR LATE TONIGHT...AS I HAVE BEEN WATCHING SOME JET ENERGY MOVING INTO NORTHERN MEXICO ON THE WATER VAPOR IMAGERY AND WE MAY DO A REPEAT OF ELEVATED CONVECTION LATE. WEDNESDAY/S POPS LOOK NIL AT THIS TIME AS UPPER RIDGING/STRONG CAP INVADES AHEAD OF A VIGOROUS UPPER WAVE MOVING INTO THE CENTRAL PLAINS THURSDAY. THIS FAR SOUTH...POPS LOOK LOW WITH TROUGH PASSING NORTH AND CAPPING WASHING OVER THE REGION. WILL STILL HAVE TO LEAVE SLIGHTS IN NORTHERN PORTION WITH SUCH A POWERFUL SYSTEM AND THE DRYLINE IN THE VICINITY. SATURDAY LOOKS LIKE THE BEST CHANCE FOR PRECIPITATION FOR NORTH TEXAS AS THE MAIN WESTERN TROUGH EJECTS INTO THE CENTRAL PLAINS AND A COOL FRONT DRIVES INTO THE REGION (DRIER CONDITIONS FINALLY?). THE FRONT WILL LAY DOWN OVER SOUTH TEXAS ON SUNDAY...FOR A BIT LONGER CHANCE FOR RAIN FOR THE SOUTHERN ZONES. DRY CONDITIONS ARE IN STORE FOR MONDAY. TUESDAY...I WILL INTRODUCE SLIGHT POPS AGAIN...AS THE GFS PROGS ANOTHER TROUGH TO APPROACH THE REGION. HOWEVER...THE ECMWF/UKMET DO NOT APPEAR TO SHARE THE GFS/S ENTHUSIASM WITH ANOTHER TROUGH...HENCE THE SLIGHT POPS AT THIS TIME. 30/SS FCSTID = 30 DFW 73 90 73 91 / 10 10 0 20 ACT 71 91 74 93 / 10 10 0 20 PRX 71 88 73 89 / 10 10 0 20 DTO 70 90 72 91 / 10 10 0 20 TKI 72 89 74 88 / 10 10 0 20 DAL 73 90 75 91 / 10 10 0 20 TRL 72 90 73 89 / 10 10 0 20 CRS 72 91 74 90 / 10 10 0 20 TPL 72 93 73 93 / 10 10 0 20 .FWD...
