.UPDATE...
DESPITE A SEEMINGLY FAVORABLE ENVIRONMENT FOR CONVECTION LATE THIS
AFTERNOON AND EVENING...THE ATMOSPHERE REMINDS US THAT EVEN WHEN
IT IS ESSENTIALLY UNCAPPED AND UNSTABLE WITH A DRY LINE TO FOCUS
ACTIVITY...IT IS STILL NOT ENOUGH TO GET CONVECTION. A CRITICAL
PART OF THE CONVECTION EQUATION IS LIFT...AND IT ALSO IS THE MOST
DIFFICULT TO DETERMINE ON A REGULAR BASIS. EVERYTHING AT THE
SURFACE WAS READY TO CONVECT...HOWEVER AS BEST WE CAN TELL...THE
UPPER LEVELS WERE NOT CONDUCIVE FOR VERTICAL OVERTURNING THIS
EVENING. AS METEOROLOGISTS IT IS FRUSTRATING THAT WE HAVE NO
OBSERVATION DATA TO SHOW WHETHER SUBTLE...YET IMPORTANT VERTICAL
MOTIONS ARE OCCURRING. INSTEAD WE RELY ON HORIZONTAL SLICES OF
DATA...AND THROUGH EQUATIONS OF FLUID DYNAMICS...WE CAN INFER
WHETHER AIR IS BEING FORCED UPWARD OR DOWNWARD...ONLY AFTER A
WHOLE LIST OF ASSUMPTIONS ARE MADE. WHETHER ONE OF THESE
ASSUMPTIONS HAS TRUMPED OUR GENERAL UNDERSTANDING AND INFERENCE OF
DYNAMIC VERTICAL MOTIONS THIS EVENING IS UNCLEAR...BUT IT IS
SOMETHING WE WOULD LIKE TO TAKE A CLOSER LOOK AT.

THE 00Z UPPER ANALYSIS SHOWS A WELL DEFINED TROUGH AXIS POSITIONED
ACROSS THE SOUTHERN PLAINS...WITH NORTH TEXAS IN A FAVORABLE
REGION OF WARM ADVECTION...AND BY INFERENCE LIFT. MODELS CONTINUE
TO ADVERTISE A STRONG VORTICITY CENTER TRACKING ACROSS THE REGION
AFTER MIDNIGHT...WHICH SHOULD ALSO AIDE IN LIFT. THE LOW LEVEL
AIR MASS REMAINS UNSTABLE AND ONLY WEAKLY CAPPED...AND IT WOULD
SEEM WE ARE JUST WAITING ON THE ATMOSPHERE ALOFT TO BECOME
FAVORABLE FOR CONVECTION THROUGH UPWARD FORCING. SINCE SO MANY
SIGNALS CONTINUE TO POINT TOWARD CONVECTION OCCURRING TONIGHT...AM
HESITANT TO LOWER POPS AT THIS POINT. RUC/NAM MODELS ADVERTISE THE
COLD FRONT NOW ACROSS SW OK BECOMING CONVECTIVELY ACTIVE AFTER
MIDNIGHT AS IT REACHES THE RED RIVER COUNTIES. WILL SHOW HIGHEST
POPS OF 50 PERCENT ALONG THE RED RIVER...BUT GRADE THEM DOWN TO
LESS THAN 20 SOUTH OF I-20. SEVERE WEATHER THREAT WILL
REMAIN...BUT GIVEN STORM MODE WILL BE MORE LINEAR...THREATS SHOULD
BE LESS SIGNIFICANT THAN EARLIER FORECAST.
