...PROLONGED AND INTENSE HEAT WAVE CONTINUES INTO FRIDAY FROM
MIDWEST TO MID-ATLANTIC...
...UNSETTLED WEATHER COULD PRODUCE SEVERE WEATHER AND EXCESSIVE
RAINFALL FOR PARTS OF THE CENTRAL AND EASTERN U.S...
APPROXIMATELY 80 MILLION PEOPLE REMAIN UNDER A HEAT HEADLINE THIS
AFTERNOON AS OUR PROLONGED HEAT WAVE CONTINUES FOR ONE MORE DAY
ACROSS THE MID-ATLANTIC, OHIO VALLEY, AND SOUTHEAST. WITHIN THIS
BROAD AREA, THE OHIO VALLEY (ALONG A PITTSBURGH TO LOUISVILLE
LINE) IS STILL EXPECTED TO EXPERIENCE EXTREME TO MAJOR HEAT
IMPACTS. FORTUNATELY, RELIEF IS ON THE WAY BY TOMORROW EVENING AS
THE RIDGE FLATTENS AND A STRONG BACK-DOOR COLD FRONT SEEPS
SOUTHWESTWARD ACROSS THE NORTHERN MID-ATLANTIC. BEHIND THE
BACK-DOOR FRONT, HIGH TEMPERATURES IN THE LOW TO MID 70'S IN THE
NORTHEAST AND NORTHERN MID-ATLANTIC SHOULD FEEL GORGEOUS IN
COMPARISON TO THE RECENT TRIPLE DIGIT HIGHS BEFORE THE FRONT
QUICKLY WEAKENS ON SATURDAY. BY THIS WEEKEND, HIGH TEMPERATURES IN
THE UPPER-80'S AND LOW 90'S SHOULD ENCOMPASS MUCH OF THE REGION,
WHICH IS MUCH CLOSER TO NORMAL FOR LATE JUNE.
AS IS TYPICAL OF JUNE, WIDESPREAD THUNDERSTORM COVERAGE CAN BE
FOUND ACROSS MUCH OF THE CENTRAL AND EASTERN LOWER 48, GENERALLY
FOCUSING ALONG A SLOW MOVING FRONTAL BOUNDARY. SOME OF THE
ORGANIZED STORMS IN THE MIDWEST, MID-ATLANTIC, AND APPALACHIANS
TODAY COULD PRODUCE SCATTERED INSTANCES OF FLASH FLOODING AND
SEVERE WEATHER PER THE LATEST WPC AND SPC FORECASTS. BY TOMORROW,
TWO DISTINCT LOW PRESSURE AREAS WILL SPLIT THE THREAT OF SCATTERED
FLASH FLOODING AND SEVERE WEATHER INTO THE INTERIOR NORTHEAST AND
NORTHERN PLAINS, RESPECTIVELY.
