...SYNOPSIS/FORECAST...
SUB-TROPICAL CONVEYOR HAS BECOME ESTABLISHED THIS EVENING DOWNSTREAM
FROM A DIGGING MID-LEVEL SHORTWAVE TROUGH OVER THE SRN GREAT BASIN. 
AS A RESULT...CONSIDERABLE MID-UPPER LEVEL MOISTENING WAS NOTED ON
SRN PLAINS 00Z SOUNDINGS.  AT THE SAME TIME...MODIFIED CP AIR MASS
WAS BEING ADVECTED NWD FROM DEEP S TX BENEATH THE HIGH LEVEL
CONVEYOR.

ISENTROPIC LIFT...AUGMENTED BY A 40-50 KT SLY LLJ AND WEAK
SUB-TROPICAL PERTURBATIONS...WILL BE FAVORABLE FOR INCREASING TSTM
THREATS LATE TONIGHT FROM PORTIONS OF NCNTRL/NERN TX INTO SRN OK. 
EVENING SOUNDINGS SUGGEST THAT CONTINUED  MOISTENING OF THE COLUMN
BELOW H7 WILL RESULT IN MUCAPE AOB 500 J/KG.  DESPITE STRONG
EFFECTIVE VERTICAL SHEAR...THE WEAK INSTABILITY EXPECTED SHOULD
MITIGATE SEVERE TSTM THREAT.
