...Severe weather and heavy rainfall threat continues in the Central and
Eastern U.S...

...Hazardous heat to focus over the Southern and Eastern U.S...

Daily chances for severe weather and heavy rainfall will continue into the
weekend as a frontal system pivots across the Nation's midsection. The
most widespread and impactful round of severe weather is expected to
impact portions of the Midwest (including the Chicago and Quad Cities
areas) this afternoon, where Tornado and Flood Watches are in effect as
thunderstorms rapidly expand in coverage and intensity over the next few
hours. A separate (but less intense) area of severe weather is also
possible today over portions of the Ohio Valley and Northeast this
afternoon ahead of a weakening lead cold front. By tomorrow afternoon,
stormy skies will be commonplace across much of the Northeast and
Mid-Atlantic as the main cold front approaches from the west, which could
produce scattered severe wind gusts. Eventually, organized thunderstorms
capable of both severe weather and excessive rainfall will re-focus over
the Central Plains on Saturday as the main cold front stalls and begins to
meander northward.

Thunderstorms aside, hazardous heat remains a concern over the Southern
and Eastern U.S. owing to the combination of high humidity, hot daytime
temperatures, and warm overnight temperatues. In fact, by tomorrow many
daily high temperature records could fall along the Eastern Seaboard from
Georgia to New York as temperatures climb towards triple digit readings.
As such, the latest experimental NWS HeatRisk outlook suggests major to
locally extreme heat impacts are possible through Saturday from the Lower
Mississippi Valley to the Northeast as the potent heat sets in.
