...EXTREMELY DANGEROUS HEAT PERSISTS ACROSS THE MIDWEST AND EAST
COAST...
...EXCESSIVE RAINFALL CONCERNS FOR PORTIONS OF THE SOUTHWEST,
SOUTHERN HIGH PLAINS, NORTHERN/CENTRAL PLAINS TODAY...
...SEVERE THUNDERSTORMS AND EXCESSIVE RAINFALL POTENTIAL ACROSS
THE UPPER/MIDDLE MISSISSIPPI VALLEY, UPPER GREAT LAKES, AND
SOUTHEAST THROUGH THURSDAY
EXTREME HEAT WARNINGS AND/OR HEAT ADVISORIES CURRENTLY EXTEND FROM
THE LOWER MISSISSIPPI VALLEY AND MIDWEST TO MUCH OF THE EAST
COAST, AFFECTING NEARLY 150 MILLION PEOPLE. THE OHIO VALLEY WILL
EXPERIENCE THE LONGEST STRETCH OF EXTREME HEAT AS IT IS LIKELY TO
PERSIST THROUGH FRIDAY. DAILY RECORD HIGH TEMPERATURES ARE
EXPECTED FROM THE OHIO VALLEY THROUGH MUCH OF THE EAST COAST TODAY
AFTER SOME LOCATIONS SET MONTHLY JUNE TEMPERATURE RECORDS ON
TUESDAY. IN FACT, TUESDAY WAS NEW YORK CITY'S HOTTEST DAY SINCE
2012. HIGH TEMPERATURES ARE FORECAST TO REACH THE UPPER 90S WITH
OVERNIGHT LOWS IN THE 70S. URBAN AREAS ALONG THE EAST COAST WILL
STRUGGLE TO DROP BELOW 80 DEGREES AT NIGHT. THE MOST SIGNIFICANT
CUMULATIVE HEAT IMPACTS ARE ANTICIPATED ACROSS THE MID-ATLANTIC
THROUGH THURSDAY. THIS IS AFTER SEVERAL CONSECUTIVE DAYS OF
OPPRESSIVE HEAT, WHICH SHOULD EXACERBATE HEAT RELATED HEALTH
IMPACTS. THIS LEVEL OF HEAT IS DANGEROUS TO ANYONE WITHOUT
EFFECTIVE COOLING AND/OR ADEQUATE HYDRATION. HEAT RELATED
ILLNESSES INCREASE SIGNIFICANTLY DURING EXTREME LONGER DURATION
HEAT. TAKE ACTION WHEN YOU SEE SYMPTOMS OF HEAT EXHAUSTION AND
HEAT STROKE.
AN UPPER TROUGH IN THE WEST WILL EJECT SHORTWAVE ENERGY OUT INTO
THE CENTRAL U.S. OVER THE NEXT COUPLE OF DAYS. THIS ENERGY WILL
LIKELY INTERACT WITH MOISTURE AND SURFACE FRONTS TO PRODUCE
SCATTERED THUNDERSTORMS FROM THE SOUTHWEST TO THE UPPER GREAT
LAKES. EARLY MORNING CONVECTION TODAY FOLLOWED BY EARLY EVENING
STORMS OVER MUCH OF NEW MEXICO AND WEST TEXAS MAY LEAD TO FLASH
FLOODING FOR THOSE AREAS. THE RUIDOSO BURN SCAR IS ESPECIALLY
SUSCEPTIBLE TO FLASH FLOODING FROM TODAY'S HEAVY RAINFALL. A
SLIGHT RISK (AT LEAST 15%) OF EXCESSIVE RAINFALL IS IN EFFECT
TODAY, FOLLOWED BY A MARGINAL RISK (AT LEAST 5%) ON THURSDAY DUE
TO LINGERING SHOWERS.
A STATIONARY FRONT DRAPED FROM THE NORTHERN/CENTRAL PLAINS TO THE
NORTHEAST WILL BE THE FOCUS FOR ADDITIONAL STORMS (SOME SEVERE)
OVER THE NEXT FEW DAYS. THE STORM PREDICTION CENTER ISSUED A
SLIGHT RISK (LEVEL 2/5) FOR PORTIONS OF CENTRAL NEBRASKA THROUGH
TO NORTHERN IOWA/SOUTHERN MINNESOTA TODAY WITH A MARGINAL THREAT
ON THURSDAY. DAMAGING WIND GUSTS AND LARGE HAIL WILL BE THE MAIN
THREATS FROM STORMS THAT MATERIALIZE.
AN UPPER-LEVEL DISTURBANCE WILL BRING SCATTERED TO ISOLATED
THUNDERSTORMS AND A MARGINAL RISK FOR EXCESSIVE RAINFALL TO THE
SOUTHEAST OVER THE NEXT COUPLE OF DAYS. SPC ISSUED A SLIGHT RISK
OF SEVERE THUNDERSTORMS FOR THESE AREAS WITH A THREAT OF SEVERE
WIND GUSTS.
