An outflow boundary from earlier thunderstorms over the Texas Hill country moved south into the Rio Grande Plains early in the evening.  Strong level convergence ahead of this outflow boundary combined with a moderately unstable airmass already in place to produce scattered strong thunderstorms over northern Webb county.  The southern portion of an upper level storm system interacted with the storms helping the southern most storm to become predominant and a severe HP supercell.  Quarter size hail was reported at this time over northern Webb county.  The storm continued to gain strength as it moved south-southeast toward the city of Laredo.  The storm moved into the North side of Laredo producing wind gusts to 70 mph.  The storm continued on a southeast path across the Northeast side of Laredo then turned south moving over the Laredo International Airport.  The storm continued south through the east side of the city along Loop 20.  The storm finally weakened as it moved into extreme southwestern Webb county.  An NWS Storm Survey concluded damage occured from straight line winds.  The survey crew estimated the highest winds of 85 to 95 mph roughly centered 1 mile around the Laredo International Airport.  70 to 80 mph winds were estimated 4 miles north and south of the airport.  The total damage path was approzimately 10 miles long with a width of 3 to 4 miles.  No fatalities or injuries were reported.
