...HEAVY RAIN AND INSTANCES OF FLASH FLOODING POSSIBLE ACROSS
PARTS OF THE LOWER MISSISSIPPI VALLEY AND UPPER MIDWEST OVER THE
NEXT FEW DAYS...
...SEVERE WEATHER POTENTIAL MOST LIKELY ACROSS THE HIGH PLAINS
THROUGH EARLY THIS WEEKEND...
...ABOVE AVERAGE WARMTH CONTINUES ACROSS THE INTERMOUNTAIN WEST,
SOUTHWEST, AND HIGH PLAINS...
MID-JUNE WEATHER PATTERN REMAINS UNDERWAY THROUGH EARLY THIS
WEEKEND AND IS EXPECTED TO FEATURE A LARGE PART OF THE CENTRAL AND
EASTERN U.S. UNDER THE POTENTIAL FOR SCATTERED THUNDERSTORMS, A
FEW OF WHICH COULD CONTAIN INTENSE RAINFALL RATES, DAMAGING WIND
GUSTS, AND HAIL. A SINGLE FRONTAL BOUNDARY STRETCHING FROM THE
NORTHERN MID-ATLANTIC BY FRIDAY MORNING ACROSS THE MIDWEST AND
INTO THE NORTHERN HIGH PLAINS WILL BE THE DIVIDING LINE BETWEEN
WARM/HUMID TO THE SOUTH AND COOLER TO THE NORTH. ALONG THIS
FRONTAL BOUNDARY, NUMEROUS THUNDERSTORMS DEVELOPING TONIGHT AND
LINGERING THROUGH FRIDAY COULD CREATE ISOLATED TO SCATTERED
INSTANCES OF FLASH FLOODING FROM THE EASTERN DAKOTAS THROUGH
CENTRAL MINNESOTA. FURTHER SOUTH, MORE WIDELY SCATTERED
THUNDERSTORMS ARE LIKELY OVER THE NEXT SEVERAL DAYS WITHIN THE
SULTRY SUMMERTIME AIRMASS STRETCHING FROM THE SOUTHERN PLAINS
THROUGH THE SOUTHEAST. MORE ORGANIZED AREAS OF THUNDERSTORMS ARE
POSSIBLE TONIGHT THROUGH FRIDAY ACROSS THE LOWER MISSISSIPPI
VALLEY TOWARDS THE WESTERN GULF COAST. THIS FOLLOWS EXTREME
RAINFALL AMOUNTS THAT OCCURRED PREVIOUSLY THROUGHOUT PARTS OF
SOUTHEASTERN TEXAS LAST NIGHT INTO EARLY THURSDAY MORNING. ANOTHER
FOCUS FOR UNSETTLED WEATHER ON FRIDAY AND SATURDAY WILL BE ACROSS
THE MID-ATLANTIC, WHERE THE LINGERING FRONTAL BOUNDARY COULD
BECOME A FOCUS FOR PERSISTENT THUNDERSTORM CHANCES. WHILE ISOLATED
DAMAGING WIND GUSTS AND HAIL IS POSSIBLE ASSOCIATED WITH THESE
SCATTERED STORMS IN THE CENTRAL AND EASTERN U.S., THE GREATEST
POTENTIAL FOR SEVERE WEATHER IS FORECAST ACROSS THE HIGH PLAINS AS
STORMS DEVELOP EACH AFTERNOON AND STRENGTHEN.
THE TEMPERATURE OUTLOOK IN THE SHORT RANGE TIME PERIOD (VALID
ENDING SUNDAY MORNING) CONTAINS ABOVE AVERAGE WARMTH ACROSS MUCH
OF THE INTERMOUNTAIN WEST, HIGH PLAINS, AND SOUTHWEST AS UPPER
RIDGING REMAINS IN PLACE NEXT TO TROUGHING OVER THE PACIFIC
NORTHWEST. WIDESPREAD HIGHS INTO THE 90S ARE ANTICIPATED, WITH
TRIPLE DIGITS ACROSS THE DESERT SOUTHWEST EXTENDING FROM SOUTHEAST
CALIFORNIA TO SOUTHERN NEW MEXICO. EXTREME HEAT WATCHES ARE IN
EFFECT BEGINNING ON SATURDAY FOR SOUTHERN ARIZONA AND PARTS OF THE
INTERIOR SOUTHERN CALIFORNIA DESERT DUE TO THE POTENTIAL FOR
MAXIMUM TEMPERATURES TO REACH 114 DEGREES. MEANWHILE, MUCH COOLER
TEMPERATURES WILL BE CONFINED TO THE NORTHERN PLAINS, UPPER
MIDWEST, GREAT LAKES, AND NEW ENGLAND TO THE NORTH OF THE
AFOREMENTIONED FRONTAL BOUNDARY. HIGH TEMPERATURES HERE WILL
STRUGGLE TO REACH HIGHER THAN THE 60S.
