The first in a multi-day event produced widespread large hail, tornadoes, and flash flooding but the largest impacts were felt in the extreme southeastern Texas Panhandle. An upper level jet streak provided the necessary lift acting upon a very unstable and strongly sheared atmosphere. Supercell thunderstorms began as isolated cells on the caprock and became more widespread once they moved off the caprock. Initially, storms produced very large hail and damaging winds but an extremely moist atmosphere and slow movement to the storms brought on flash flooding. The most damaging impacts came in Hall County where a nearly stationary storm dropped up to eight inches of rain. The extreme runoff from the storms inundated normally dry washes and creek beds. The floods damaged or destroyed several bridges and roadways and also lead to high water rescues in Lakeview (Hall County).

Flood cause: Heavy Rain
Property damage: 5.00M
Crop damage: 0.00K
Reported by: NWS Storm Survey

The same storm responsible for producing a large, EF-2 tornado near Plaska also produced significant flash flooding over much of northern Hall County late this afternoon.  Additional rounds of thunderstorms through the evening would go on to produce eight inches of rain as measured by a NWS CO-OP observer in Estelline.  The storm survey discovered significant flood damage to bridges, roads and a golf course in Estelline which had large chasms cut into the property.  Also, one SUV was swept off US Highway 256 about five miles northeast of Estelline after driving through raging floodwaters that consumed a shallow bridge.  The two occupants of the vehicle were rescued and unharmed, but their vehicle was a complete loss from water damage.  The total flood damage to infrastructure alone would likely reach several million USD.

Tornado in HALL, TEXAS
From 22-MAY-16 17:44:00 to 22-MAY-16 17:59:00 (CST-6)
Location: LAKEVIEW
Tornado F-scale: EF2
Property damage: 150.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

A large tornado developed near Plaska late this afternoon and moved slowly southeastward for the next 15 minutes before dissipating.  Several storm chasers documented this tornado as it grew into a wedge shape while wrapping in rain curtains.  This tornado and damaging RFD winds toppled several utility poles, heavily damaged and stripped some trees, and destroyed a barn.  The damage was found to be consistent with EF-2 winds.  There may have been additional, smaller tornadoes concurrently or following this large tornado, however insufficient video evidence and few damage indicators precluded an explicit entry of these tornadoes.
