DISCUSSION...
A SOMEWHAT WIDE AND BROKEN LINE OF SHOWERS AND THUNDERSTORMS HAS
DEVELOPED AND IS PUSHING THROUGH THE AREA THIS AFTERNOON AHEAD OF
AN APPROACHING COLD FRONT. A COUPLE OF STORMS HAVE BEEN ON THE
STRONGER SIDE BUT INSTABILITY REMAINS LARGELY LIMITED WITH CAPES
AT OR UNDER 500 J/KG. SPC HAS THE AREA IN A MARGINAL RISK THIS
AFTERNOON BUT HAS RECENTLY INDICATED ONLY A 20% CHANCE OF WATCH
ISSUANCE.
