   SOUTHERN CT FOR ANOTHER HOUR OR SO WHERE MODEST INSTABILITY REMAINS
   IN THE PRESENCE OF STRONG SHEAR...AND LIFT AHEAD OF THE SOUTHWARD
   ADVANCING COLD FRONT CAN MAINTAIN/PROMOTE A FEW STRONGER CONVECTIVE
   UPDRAFTS. LATEST HRRR DEPICTS CONVECTION SPREADING INTO THE AREA
   BETWEEN 0100-0200 UTC/10-11PM EDT SO A LOCAL WATCH EXTENSION FROM
   NEW HAVEN COUNTY EASTWARD MAY BE NEEDED.
