Area forecast discussion, May 1, 2:30 AM CDT, 1 hour 54 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NASHVILLE TN 230 AM CDT WED MAY 1 2002 BUSY SHIFT AND NOT MUCH TIME TO LOOK AT ANYTHING BUT RADAR AS WARNINGS ARE FLYING OUT OF HERE IN A HURRY. ONE REPORT FROM A SPOTTER EARLIER OF 70 MPH AS STORM RACED THROUGH THE MAURY COUNTY AREA. LARGE HAIL AND WIND DAMAGE HAS ALSO BEEN A PROBLEM WITH MANY OF THESE STORMS. VISIBLE LIGHTNING HAS BEEN WHITE IN NATURE WHICH GENERALLY IS RESERVED FOR THE MORE INTENSE STORMS. ANOTHER ROUND OF STORMS STARTING TO FIRE ALONG BOUNDARY IN FAR WESTERN KENTUCKY PER SATELLITE AND DOPPLER RADARS. THICKNESS WOULD WORK STORMS DOWN INTO MID STATE SHORTLY. SOME OF THESE WILL BE SEVERE WITH DAMAGING WINDS AND LARGE HAIL. AM VERY MUCH CONCERNED WITH LATER TODAY AND TONIGHT AS THERMODYNAMICS BECOME VERY UNSTABLE OVER MIDDLE TENNESSEE AS BY 00Z THIS EVENING THE SWEAT INDEX JUMPS TO NEAR 400 AND TO 448 BY MIDNIGHT AS LOW LEVEL SHEAR INCREASES. HODOGRAPH AT 06Z TONIGHT LOOKS LIKE A TROUT LINE WITH 0-3 KM VALUES AROUND 585 M2/S2. POSITIVE ENERGY REALLY CLIMBS THIS AFTERNOON AND TONIGHT WITH SOME INDICATIONS OF CAPE IN EXCESS OF 4000 J/KG AROUND 00Z. I THINK ANYTHING THAT FIRES THIS AFTERNOON AND TONIGHT WILL BE SEVERE AND TORNADIC SUPERCELLUAR IN NATURE. HAVE GINNED UP FORECAST IN IFPS BUT HAVE MADE ONLY MINOR TWEAKS AND KEPT THE GENERAL THEME OF THE DAYSHIFT FORECAST.
