URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 105
NWS Storm Prediction Center Norman OK

while spreading east-northeastward into east central Texas and
northwestern Louisiana. The storm environment will support embedded
supercells and bowing segments capable of producing tornadoes and
damaging winds as it warms and moistens quickly at the surface from
Texas into Louisiana immediately in advance of the storms.
The tornado watch area is approximately along and 55 statute miles
north and south of a line from 50 miles northwest of College Station
TX to 70 miles northeast of Natchitoches LA. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU5).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
