...Dangerous heat continues across the Gulf Coast this weekend...

A relatively quiet period is in store for the CONUS this weekend.
Scattered showers and thunderstorms are expected to focus around a cold
front dropping through the Middle Mississippi Valley and Tennessee Valley
today. Temperatures in the Midwest are likely to cool down on the backside
of this cold front after a blistering week of dangerously record setting
temperatures. Unfortunately, extreme heat and abnormally high overnight
temperatures will persist in the South out ahead of the cold front through
this weekend. Widespread record high and low temperatures are likely to be
tied or broken across the Gulf Coast this weekend. Excessive Heat Warnings
and Heat Advisories are currently in effect from central Texas to the
Florida Panhandle and up through the Lower Mississippi Valley. Heat of
this intensity poses a health risk to anyone without effective cooling
and/or adequate hydration. Do not underestimate the potential for
heat-related illness--have a way to break your heat exposure, cool down
and stay hydrated.

Shortwave energy embedded within the Southwest ridge will trigger rounds
of storms and scattered heavy rainfall over the Carolinas on Sunday. A
large upper low stationed offshore from the Pacific Northwest and a
building ridge over the Rockies will support above average temperatures
across the West through early next week. The quiet period may come to an
end early next week as a retreating ridge from the Southeast gives way to
the ascent of subtropical moisture into the Florida peninsula and the
Southeast.
