As two potent upper level jet streams converged over West Central Texas on April 26, they interacted with a dryline to result in the rapid development of supercells.  These supercells produced large hail, damaging winds and isolated tornadoes across the area.  Later that evening, the supercells congealed into a line of storms or a quasi-linear convective system that may have generated the tornado near Lake Brownwood and the intense winds in Mason. On the 27th, isolated severe storms formed and resulted in a few reports of large hail across Brown and San Saba Counties.

Thunderstorm Wind in MASON, TEXAS
From 26-APR-15 21:59:00 to 26-APR-15 22:14:00 (CST-6)
Location: KOOCKVILLE
Magnitude: 91.00 EG
Property damage: 0.00K
Crop damage: 0.00K
Reported by: NWS Employee

A National Weather Service survey team found evidence of damage consistent with winds of 95 to 105 mph.  The damaging thunderstorms impacted the south side of Mason.  Most of the damage and debris pointed towards the east.  The damaging winds snapped large oak tree trunks and broke the glass of a sliding glass door.  Wind driven debris also broke windows in a couple of homes and the back window of a brand new truck.  The high winds uprooted trees, broke numerous tree limbs, peeled off some roof covering and even blew a heavy deer blind from a nearby pasture onto U.S. Highway 87.  This downburst was about a mile long and about 175 yards wide.  There was some evidence this damage path may have also been associated with a tornado as the path was narrow and there was some convergence along the path.  However, the evidence was somewhat inconclusive.
