SPOTTY SHOWERS DEVELOPING ACROSS LOWER TOLEDO BEND LAKE...OTHERWISE AWAITING CONVECTION TO DEVELOP NW OF I-30 CORRIDOR AS UPPER TROUGH APPROACHES FROM THE WEST. LATEST MSAS/LAPS DATA SHOWING INSTABILITY BEGINNING TO INCREASE UPSTREAM WITH BREAKS IN OVC ALLOWING TEMPS TO SOAR INTO THE 70S ACROSS MUCH OF N/NE TX. 18Z SOUNDING FROM FTW CONTINUES TO SHOW A CAP IN PLACE BUT SHOULD ERODE FROM THE TOP DOWN AS COOLER AIR ALOFT AND LIFT ACCOMPANIES THE TROUGH. SOMEWHAT CONCERNED THAT IF THE CAP DOES BREAK...LOW WETBULB ZEROES AND COLD AIR ALOFT COULD RESULT IN LARGE HAIL POTENTIAL MAINLY ACROSS NE TX/ SE OK INTO SW AR. THIS AREA IS IN A SLIGHT RISK FOR TNGT SO WILL GO AHEAD AND ADD CHANCE OF SVR STORMS TO THESE GROUPS AND MENTION HAIL POTENTIAL. AS THE NIGHT PROGRESSES...LOOKING FOR STORMS TO BECOME MORE LINEAR ALONG PRE FRONTAL TROUGH WITH NOT MUCH IN THE WAY OF SVR POTENTIAL FURTHER EAST. DRY SLOT SHOULD BE APPROACHING OUR EXTREME WESTERN ZONES BY MIDNIGHT WITH A QUICK END TO THE PRECIP. WRAP AROUND NOT LOOKING QUITE AS IMPRESSIVE WITH COMMA HEAD LIFTING WELL NORTH OF FA. FOR THIS REASON...HAVE REDUCED POPS EARLY TUE BUT STILL GOING LIKELY IN THE EAST AS LINE SHOULD BE OVER THIS REGION NEAR SUNRISE TUE AM. CROSS SECTIONS SHOWING LOW LEVEL CU MIXING/ ERODING FROM WEST TO EAST DURING THE DAY TUE WHICH MAY ALLOW FOR MORE OF A WARM UP ACROSS E TX THAN FCST. WINDS MAY APPROACH LAKE WIND CRITERIA TUE BUT GRADIENT SHOULD RELAX ENOUGH TUE NIGHT WITH MOSTLY CLEAR SKIES TO ALLOW FOR AMPLE COOLING. CLOSE ON THE HILLS OF TNGTS TROUGH IS A WEAKER ONE APPROACHING AREA LATE WED INTO THU. JUST HIGH LEVEL MOISTURE WITH THIS SYSTEM THUS... CHRISTMAS DAY MAY BE MOSTLY CLOUDY BUT DRY. SW FLOW REMAINS THROUGH EARLY NEXT WEEK AS ANOTHER SHORTWAVE EJECTS OUT OF GREAT BASIN TROUGH LATE SUNDAY INTO MONDAY. SOME QUESTION ON THE PROGRESS OF THIS NEXT FRONT WITH SW FLOW ALOFT...FOR NOW WILL LIMIT POPS TO SAT INTO SUN AND LEAVE MONDAY DRY BUT THIS COULD CHANGE. 13 && .SHV WATCHES/WARNINGS/ADVISORIES...
