..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.
