Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 245 PM CDT MON JUL 22 2002 ACTIVE CONVECTION IS ONGOING ACROSS MUCH OF THE FORECAST AREA THIS AFTERNOON. NO AVAILABLE SOUNDING HERE THIS MORNING DUE TO EQUIPMENT PROBLEMS...BUT BIRMINGHAM SOUNDING FROM TODAY SHOWED VERY UNSTABLE AIRMASS IN PLACE. LATEST WATER VAPOR IMAGERY SHOWS SOME DRY AIR ACROSS NORTHERN MISSISSIPPI. THIS DRY AIR IS HELPING TO DESTABILIZE THE AIRMASS OVER MUCH OF MISSISSIPPI. WITH A COLD FRONT DIPPING INTO NORTHERN MISSISSIPPI AND NORTHEAST LOUISIANA BY TUESDAY NIGHT...EXPECT CONTINUED SCATTERED CONVECTIVE ACTIVITY ON TUESDAY IN THE CONTINUED WARM AND UNSTABLE AIRMASS. WILL ALSO CONTINUE MENTION OF SCATTERED SHOWERS AND THUNDERSTORMS OVERNIGHT TUESDAY NIGHT DUE TO THE INFLUENCE OF THE FRONT. THE AMOUNT OF ACTIVITY ON WEDNESDAY WILL DEPEND ON HOW FAR SOUTH THE FRONT IS ABLE TO MOVE. THE FRONT SHOULD CONTINUE TO WEAKEN AS IT MOVES SOUTH...BUT DRIER AIR SHOULD AT LEAST GET INTO NORTHERN SECTIONS ON WEDNESDAY AND ALLOW FOR REDUCED CONVECTION THERE. FOR TEMPERATURES...THE APPROACHING FRONT WILL HAVE MINIMAL EFFECT ON TEMPERATURES IN OUR FORECAST AREA. THE AIR AT THE SURFACE WILL CONTINUE TO BE VERY WARM AND HUMID WITH THE DEEP LAYER OF DRIER AIR ABOVE THE SURFACE HELPING TO SUPPRESS CONVECTION AND CLOUDS BUT ALLOWING MORE SUNSHINE TO KEEP THINGS SEASONABLY HOT. IN THE EXTENDED...FRIDAY THROUGH MONDAY...THE LATEST AVN MODEL RUN IS STILL SHOWING DRIER AIR IN THE AREA FRIDAY...ESPECIALLY IN THE NORTHERN HALF OF THE FORECAST AREA. THE AVN EXTENDED MODEL IS BUILDING A 500 MB RIDGE OVER SOUTHEASTERN U.S. WHICH SHOULD HELP TO REDUCE THE AMOUNT OF CONVECTION IN THE LOWER MISSISSIPPI VALLEY THROUGH THE EXTENDED PERIOD. WILL GENERALLY GO WITH JUST SLIGHT CHANCE OF AFTERNOON AND EVENING CONVECTION THROUGH THE PERIOD. HIGH TEMPERATURES SHOULD BE UP AROUND 95 EACH DAY ACROSS THE REGION.
