...SYNOPSIS/FORECAST...
WATER VAPOR IMAGERY INDICATES A COMPACT MID-LEVEL VORT MAX EMERGING
OVER THE HIGH PLAINS OF NRN/CNTRL MT. STRONG DCVA WILL SPREAD
EWD/ESEWD TOWARD THE UPPER MS VALLEY THROUGH TONIGHT IN TANDEM WITH
THE PROGRESSION OF THE VORT MAX. DESPITE THE PAUCITY OF TROPOSPHERIC
MOISTURE...DEEP ASCENT SHOULD BE SUFFICIENT IN THE PRESENCE OF STEEP
LOW/MID-LEVEL LAPSE RATES FOR ISOLATED WEAK THUNDERSTORMS TO
ACCOMPANY THIS SYSTEM FROM FAR ERN MT EWD TO W-CNTRL MN INTO THE
EARLY OVERNIGHT HOURS. BUOYANCY WILL BE TOO LIMITED FOR ANY SVR
POTENTIAL. ELSEWHERE...DRY AND/OR CONVECTIVELY STABLE THERMODYNAMIC
PROFILES WILL MITIGATE THE THUNDERSTORM POTENTIAL.
