TNZ005>011-022>034-056>066-075>080-093>097-231030- HAZARDOUS WEATHER OUTLOOK...UPDATED NATIONAL WEATHER SERVICE NASHVILLE TN 1146 AM CDT MON JUL 22 2002 LOOK FOR SCATTERED CONVECTION TO CONTINUE DEVELOPING ACROSS THE MID STATE FROM LATE MORNING ON. ABUNDANT MOISTURE AVAILABLE IN THE ATMOSPHERE, COUPLED WITH DEEP INSTABILITY, WILL BE SUFFICIENT TO ALLOW NUMEROUS HEAT DRIVEN THUNDERSTORMS CAPABLE OF PRODUCING VERY HEAVY RAINFALL. WITH RELATIVELY WEAK UPPER LEVEL WINDS, THESE THUNDERSTORMS WILL ALSO BE SLOW MOVING, ALLOWING FOR SIGNIFICANT ACCUMULATION OF RAINFALL OVER AFFECTED AREAS IN A SHORT TIME. THEREFORE, SOME URBAN AREAS MIGHT SEE BRIEF FLOODING OF STREETS DURING THUNDERSTORM ACTIVITY. ALTHOUGH WIDESPREAD SEVERE WEATHER IS NOT ANTICIPATED, THE STORM PREDICTION CENTER HAS PLACED THE SOUTHERN HALF OF MIDDLE TENNESSEE AND THE CUMBERLAND PLATEAU IN A SLIGHT RISK FOR SEVERE WEATHER. THEREFORE, ACTIVATION OF EMERGENCY MANAGERS AND SPOTTERS MAY BE NEEDED FOR ISOLATED SEVERE THUNDERSTORMS. ROSE
