SUMMARY…Thunderstorms coverage is expected to increase over the
next few hours along and ahead of a cold front pushing eastward
across the region. Environmental conditions support strong to severe
storms. An initially cellular mode will favor large hail and
damaging gusts before a transition to a more linear storm mode
favors primarily damaging gusts.

statute miles north and south of a line from 30 miles west of
Lexington KY to 60 miles north northeast of White Sulphur Springs
WV. For a complete depiction of the watch see the associated watch
outline update (WOUS64 KWNS WOU8).
