A convective complex developed over the western Texas Panhandle during the late afternoon and early evening hours of the 4th. This system resulted in damaging winds and large hail as it propagated south-southeastward over the west Texas South Plains during the evening. The complex evolved into a broken line of organized multicell and occasional supercellular storms as it quickly swept southward along a pre-existing outflow boundary. Several of the more intense cells within the complex produced extreme wind gusts and golfball size hail. The most significant impacts occurred over western Lubbock County, where a swath of extreme thunderstorm winds and wind-blown hail damaged light weight structures and instrumentation at the Texas Tech University West Texas Mesonet facility at Reese Center.

Thunderstorm Wind in LUBBOCK, TEXAS
From 04-JUN-09 20:30:00 to 04-JUN-09 20:37:00 (CST-6)
Location: REESE AFB
Magnitude: 82.00 MG
Property damage: 25.00K
Crop damage: 0.00K
Reported by: Mesonet

The Texas Tech University West Texas Mesonet site and research complex at Reese Center obtained high-resolution measurements of a damaging swath of thunderstorm winds between 20:30 CST and 20:37 CST, as an intense supercell storm produced extreme outflow winds and large hail in the Reese Center vicinity. The Texas Tech University West Texas Mesonet site at Reese center initially recorded a 74 mph gust at 20:30 CST and a 65 mph gust at 20:35 CST. Meanwhile, additional research instrumentation on the west end of the complex measured numerous gusts in the 80 mph and 90 mph range. A peak gust of 94 mph was measured by one of these instruments at a height of thirteen feet above the ground. Fortunately, the strongest winds occurred over open terrain immediately west of the Reese Center complex, however, a number of light weight structures sustained damage from the winds that were at times accompanied by golfball size hail. Some instrumentation was destroyed. The roof was partially removed from at least one large storage barn, and other out door equipment was displaced and heavily damaged. No injuries were reported.
