...DISCUSSION...

An active weekend expected across the middle Ohio Valley into the
central Appalachians with risk for severe thunderstorms, heavy
rainfall and potential flooding. Temperatures will remain very warm
and humid with highs in the mid 80s to low 90s.  Maximum heat index
values will peak around 100 degrees over the Tri-State area this
afternoon, and in the mid to upper 90s elsewhere across the lowlands
each afternoon this weekend. The cold front triggering all the
thunderstorms, will move through Sunday night, but one last round of
thunderstorms is possible Monday afternoon and evening, as a second
cold front moves through. Cooler, refreshing canadian air brings
relief from the heat, humidity, and the thunders torms, during the
middle of next week. It will warm up again, ahead of another cold
front expected to arrive late next week, but another shot of cooler,
less humid air is expected next weekend.
