...RECORD-BREAKING HEAT FORECAST ACROSS PARTS OF THE SOUTHWEST AND
SOUTH-CENTRAL UNITED STATES...
...DEVELOPING STORM SYSTEM TO BRING UNSETTLED WEATHER TO THE OHIO
VALLEY, GREAT LAKES, AND NORTHEAST THIS WEEKEND...
..LOCALLY HEAVY RAIN POSSIBLE OVER SOUTHEAST FLORIDA
PREDOMINANT UPPER-LEVEL RIDGING STRETCHING FROM THE SOUTHWEST TO
THE SOUTHERN HIGH PLAINS WILL ALLOW FOR ANOTHER DAY OF
RECORD-BREAKING HEAT ACROSS PARTS OF NEVADA AND ARIZONA TODAY.
HIGH TEMPERATURES ARE FORECAST TO REACH INTO THE UPPER 90S AND
TRIPLE DIGITS, WITH TEMPERATURES ONLY EXPECTED TO BE A FEW DEGREES
COOLER THIS WEEKEND. MEANWHILE, HEAT IS ANTICIPATED TO EXPAND
ACROSS THE SOUTH-CENTRAL U.S. BY SATURDAY AS HIGHS INTO THE
MID-90S ENGULF THE SOUTHERN PLAINS. WELL ABOVE AVERAGE
TEMPERATURES SHOULD SPAN INTO THE CENTRAL PLAINS AND
MID-MISSISSIPPI VALLEY AS WELL, WITH NUMEROUS DAILY RECORD HIGH
TEMPERATURES POSSIBLE. COOLER AND MORE FALL-LIKE TEMPERATURES WILL
BE FOUND ACROSS THE EAST TODAY, WITH AREAS OF FROST LIKELY FROM
THE CENTRAL APPALACHIANS TO THE NORTHEAST EARLY THIS MORNING.
THE NEXT AUTUMN COLD FRONT TO IMPACT THE NATION IS FORECAST TO
CROSS THE GREAT LAKES AND NORTHEAST BY SATURDAY BEFORE STALLING
OVER THE MID-ATLANTIC ON SUNDAY. AN AREA OF LOW PRESSURE
DEVELOPING ALONG THIS FRONTAL BOUNDARY IS EXPECTED TO DEEPEN AND
MOVE EASTWARD OVER THE OHIO VALLEY AND LOWER GREAT LAKES. AREAS OF
SHOWERS AND THUNDERSTORMS SURROUNDING THE SYSTEM MAY DAMPEN
OUTDOOR ACTIVITIES, WITH A FEW ISOLATED STRONG THUNDERSTORMS
POSSIBLE BETWEEN EASTERN KENTUCKY AND WEST VIRGINIA.
FOLLOWING IN THE WAKE OF HURRICANE MILTON, STRONG NORTHEASTERLY
FLOW AIDED BY A HIGH PRESSURE SYSTEM OVER THE SOUTHERN
APPALACHIANS WILL PROVIDE THE POTENTIAL FOR CONTINUED COASTAL
HAZARDS AS WELL AS LOCALLY HEAVY RAIN ALONG THE ATLANTIC COAST OF
FLORIDA. DEVELOPING THUNDERSTORMS ALONG THE SOUTHEAST FLORIDA
COASTLINE IN PARTICULAR MAY REMAIN SOMEWHAT STATIONARY DUE TO
OPPOSING FLOW ALOFT, WHILE ALSO CONTAINING INTENSE RAINFALL RATES.
A MARGINAL RISK (LEVEL 1/4) OF EXCESSIVE RAINFALL HAS BEEN ISSUED
FOR THIS REGION ON SATURDAY AND SUNDAY IN ORDER TO HIGHLIGHT THE
THREAT OF LOCALIZED FLASH FLOODING.
