A STATIONARY OUTFLOW BOUNDARY THAT EXTENDS FROM SRN IA NWWD THROUGH

NEB. ENHANCED LIFT ASSOCIATED WITH THE SLY NOCTURNAL LOW LEVEL JET
INTERACTING WITH THESE BOUNDARIES WILL CONTINUE TO SUPPORT
THUNDERSTORM DEVELOPMENT NEXT COUPLE HOURS. HOWEVER...STORMS ARE
EXPECTED TO GRADUALLY WEAKEN AS RESERVOIR OF STRONGER INSTABILITY
