CONTINUE TO RISE INTO THE LOW 50S AFTER MIDNIGHT ACROSS THE CWA.

WIND SHEAR ARND 400 M2/S2...WILL STILL HAVE A CHC FOR TSRA OVERNIGHT.
THE SVR THREAT OVER THE TN VALLEY IS BEGINNING TO DIMINISH BUT CANT
RULE OUT A FEW STORMS WITH WIND GUSTS UP TO 50 MPH...SMALL HAIL AND
LOCALIZED HVY RAIN OVERNIGHT. RAIN HAS ALREADY MOVED INTO EXTREME NW
