URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 284
NWS Storm Prediction Center Norman OK
700 PM CDT Sat May 27 2017
The NWS Storm Prediction Center has issued a
* Tornado Watch for portions of
Northern and western Arkansas
* Effective this Saturday night and Sunday morning from 700 PM
until 200 AM CDT.
* Primary threats include...
A few tornadoes and a couple intense tornadoes possible
Widespread damaging winds likely with isolated significant gusts
to 80 mph possible
Scattered large hail and isolated very large hail events to 2.5
inches in diameter possible
SUMMARY...Severe thunderstorms will continue to develop within a
highly unstable environment from far southern Missouri into northern
and western Arkansas. Tornadoes will especially be possible with any
storm along a roughly west-east outflow boundary along the
Missouri/Arkansas border vicinity, while semi-discrete supercells or
evolving line-embedded mesovortices would also pose a tornado risk.
Otherwise, widespread and locally intense damaging winds will be
highly likely as storms accelerate east/southeastward this evening.
The tornado watch area is approximately along and 70 statute miles
north and south of a line from 60 miles west southwest of Harrison
AR to 35 miles east southeast of Poplar Bluff MO. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU4).
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.
