URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 287
NWS Storm Prediction Center Norman OK
1000 PM CDT Sat May 27 2017

* Tornado Watch for portions of
Eastern Arkansas
Northern Mississippi
Western Tennessee
* Effective this Saturday night and Sunday morning from 1000 PM
until 500 AM CDT.
* Primary threats include...
A couple tornadoes possible
Isolated significant damaging wind gusts to 80 mph possible
Isolated very large hail events to 2 inches in diameter possible
SUMMARY...A fast-moving convective line will continue to move
southeastward across eastern Arkansas into western Tennessee,
including the Memphis metro area. The most intense storms will favor
areas along and south/southwest of an arcing outflow boundary, with
widespread damaging winds a distinct possibility aside from some
line-embedded tornado risk. These storms will eventually move into
northern Mississippi overnight.
The tornado watch area is approximately along and 50 statute miles
north and south of a line from 35 miles south southwest of Jonesboro
AR to 50 miles northeast of Tupelo MS. For a complete depiction of
the watch see the associated watch outline update (WOUS64 KWNS
WOU7).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and severe thunderstorms in and close to the watch
area. Persons in these areas should be on the lookout for
threatening weather conditions and listen for later statements
and possible warnings.
