SUMMARY...Quasi-linear bands of strong to severe convection will

continue to move northeastward overnight and pose a damaging wind

risk, along with some potential for a tornado or two and/or severe

hail. Within a highly sheared environment, these well-organized

storms are largely favoring an area along an outflow boundary.



The severe thunderstorm watch area is approximately along and 30

statute miles east and west of a line from 115 miles south of

Jonesboro AR to 35 miles east northeast of Poplar Bluff MO. For a

complete depiction of the watch see the associated watch outline

update (WOUS64 KWNS WOU9).



PRECAUTIONARY/PREPAREDNESS ACTIONS...



REMEMBER...A Severe Thunderstorm Watch means conditions are

favorable for 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. Severe thunderstorms can and occasionally do produce

tornadoes.
