...EPISODES OF SEVERE THUNDERSTORMS ON TAP FOR PORTIONS OF THE
CENTRAL AND SOUTHERN HIGH PLAINS, THE TENNESSEE AND OHIO VALLEYS,
SOUTHERN NEW ENGLAND, AND INTO THE SOUTHEAST FRIDAY AND SATURDAY...
...HEAVY SHOWERS CAPABLE OF PRODUCING INSTANCES OF FLASH FLOODING
EXPECTED ACROSS PORTIONS OF THE CENTRAL/SOUTHERN HIGH PLAINS
EASTWARD INTO PARTS OF THE TENNESSEE VALLEY, MID-SOUTH, AND
SOUTHERN NEW ENGLAND INTO THE WEEKEND...
...BELOW NORMAL TEMPERATURES IN STORE FROM THE ROCKIES INTO THE
GREAT LAKES WHILE HEAT BUILDS ACROSS THE SOUTHERN U.S. AND THE
PACIFIC NORTHWEST THROUGH SATURDAY...
A SLOW-MOVING, WAVY FRONTAL SYSTEM STRETCHING FROM THE NORTHEAST
TO THE OHIO/TENNESSEE VALLEYS TO THE CENTRAL/SOUTHERN HIGH PLAINS
WILL BE THE FOCUS FOR SEVERAL ROUNDS OF SEVERE THUNDERSTORMS AND
DRENCHING DOWNPOURS FRIDAY INTO THE FIRST HALF OF THE WEEKEND.
WARM AND MOIST AIR SOUTH OF THE WAVY FRONT WILL CLASH WITH COOLER
AND DRIER AIR TO THE NORTH OF IT, SETTING THE STAGE FOR AN ACTIVE
STRETCH OF WEATHER FOR A LARGE PORTION OF THE COUNTRY. SEVERE
THUNDERSTORMS CAPABLE OF PRODUCING VERY LARGE HAIL, DAMAGING
WINDS, AND A FEW TORNADOES WILL BE PARTICULARLY CONCERNING ACROSS
PARTS OF THE CENTRAL AND SOUTHERN HIGH PLAINS TODAY, WITH THE
STORM PREDICTION CENTER HIGHLIGHTING THE THREAT WITH AN ENHANCED
RISK (LEVEL 3/5) OF SEVERE WEATHER. STRONG TO SEVERE THUNDERSTORMS
WILL ALSO BE POSSIBLE FARTHER EAST ACROSS PARTS OF THE
TENNESSEE/OHIO VALLEYS AND SOUTHERN NEW ENGLAND, WITH A SLIGHT
RISK (LEVEL 2/5) OUTLINING THE POTENTIAL FOR STRONG WINDS, HAIL,
AND EVEN AN ISOLATED TORNADO OR TWO. IN ADDITION TO THE SEVERE
WEATHER THREAT, THESE SAME REGIONS WILL ALSO HAVE TO CONTEND WITH
BOUTS OF HEAVY RAINFALL, SOME OF WHICH COULD LEAD TO SCATTERED
INSTANCES OF FLASH FLOODING. ON SATURDAY, THE RISK FOR SEVERE
WEATHER AND EXCESSIVE RAINFALL WILL SHIFT SOUTH AND EAST A BIT,
TARGETING MORE OF THE MID-SOUTH, TENNESSEE VALLEY, AND THE
SOUTHEAST AS ADDITIONAL WAVES OF LOW PRESSURE DEVELOP ALONG THE
SLOW-MOVING FRONT. SIMILAR TO TODAY, HEAVY SHOWERS AND STRONG TO
SEVERE THUNDERSTORMS WILL THREATEN TO PRODUCE DAMAGING WINDS,
LARGE HAIL, A COUPLE TORNADOES, AND FLASH FLOODING.
IN THE WAKE OF THE FRONT, HIGH PRESSURE BUILDING IN FROM THE
NORTHWEST WILL LEAD TO A PERIOD OF COOLER THAN NORMAL TEMPERATURES
FROM PARTS OF THE ROCKIES AND THE INTERMOUNTAIN WEST EASTWARD TO
THE GREAT LAKES THROUGH SATURDAY. THE COOLEST TEMPERATURE
ANOMALIES WILL BE FOUND FROM SOUTHEAST WYOMING AND WESTERN
NEBRASKA TO EASTERN COLORADO AND WESTERN KANSAS TODAY WITH HIGH
TEMPERATURES 10 TO 15 DEGREES BELOW NORMAL. ON THE OTHER SIDE OF
THE COIN, SUMMER-LIKE HEAT WILL BUILD ACROSS THE SOUTHERN TIER OF
THE U.S. AND MUCH OF THE PACIFIC NORTHWEST THROUGH THE WEEKEND.
TEMPERATURES OF 10 TO AS MUCH AS 25 DEGREES ABOVE NORMAL WILL
TRANSLATE TO HIGHS WELL INTO THE 90S AND 100S. IN FACT, BY SUNDAY,
HIGH TEMPERATURES COULD THREATEN RECORDS FOR PARTS OF THE PACIFIC
NORTHWEST, WITH EVEN MORE RECORDS POSSIBLE ON MONDAY.
