...STRONG TO SEVERE THUNDERSTORMS WITH FLOODING RAINFALL THIS
MORNING ACROSS THE CENTRAL U.S. ARE EXPECTED TO BE LESS INTENSE AS
THEY MOVE FARTHER INTO THE SOUTHERN PLAINS...
...STRONG TO SEVERE THUNDERSTORMS ARE FORECAST TO MOVE ACROSS THE
MID-ATLANTIC AND THE NORTHEAST LATER TODAY AND THROUGH TONIGHT...
...HEAT WILL BUILD OVER THE PACIFIC NORTHWEST AS MUCH COOLER AIR
SURGES INTO THE MID-SECTION OF THE COUNTRY TO END THE HEAT IN THE
EAST...
A WEATHER PATTERN FAVORING COLD AIR INTRUSIONS FROM CANADA WILL
BRING REFRESHINGLY COOL AIR TO REPLACE THE HEAT AND HUMIDITY
ACROSS MUCH OF THE EASTERN TWO-THIRDS OF THE COUNTRY DURING THE
NEXT COUPLE OF DAYS. HOWEVER, THIS PROCESS WILL LEAD TO FORMATION
OF SHOWERS AND THUNDERSTORMS WITH POSSIBLE SEVERE WEATHER AND
FLOODING RAINFALL. THE MOST INTENSE RAIN AND THUNDERSTORMS FOUND
THIS MORNING ACROSS THE CENTRAL U.S. ARE EXPECTED TO LOSE
INTENSITY AS THEY MOVE TOWARD THE SOUTHERN PLAINS AND THE LOWER
MISSISSIPPI VALLEY LATER TODAY. HOWEVER, A LOW PRESSURE WAVE
DEVELOPING ALONG THE COLD FRONT WILL LIKELY TRIGGER ADDITIONAL
STRONG TO SEVERE THUNDERSTORMS FROM THE MIDWEST TO THE OHIO VALLEY
AND THROUGH THE LOWER GREAT LAKES THIS MORNING. INCREASINGLY
SOUTHERLY WIND AHEAD OF THE COLD FRONT WILL TEND TO BRING HEAT AND
HUMIDITY UP THE EAST COAST ONCE AGAIN THIS AFTERNOON WITH HIGH
TEMPERATURES SOARING TO NEAR 100 DEGREES IN CENTRAL NORTH
CAROLINA. THE HEAT AND HUMIDITY WILL AID THE PRODUCTION OF
ADDITIONAL STRONG TO SEVERE THUNDERSTORMS FROM THE MID-ATLANTIC TO
THE NORTHEAST LATER TODAY AHEAD OF THE COLD FRONT AS THE LOW
PRESSURE WAVE INTENSIFIES. DAMAGING WINDS APPEAR TO BE THE MAIN
CONCERN WITH THIS EPISODE OF STRONG TO SEVERE THUNDERSTORMS. BY
MONDAY MORNING, THE COLD FRONT IS FORECAST TO MOVE OFF THE NEW
ENGLAND COAST AS THE REFRESHINGLY COOL AIR FROM CANADA DROPS
TEMPERATURES INTO THE 40S AND 50S ACROSS THE NORTHERN AND CENTRAL
U.S. BY MONDAY MORNING. THESE COOL READINGS ARE FORECAST TO SPREAD
INTO NEW ENGLAND BY TUESDAY MORNING.
ELSEWHERE, MONSOONAL SHOWERS ACROSS THE FOUR CORNERS AND SOUTHERN
ROCKIES WILL BE MOST ACTIVE LATER TODAY BUT SHOULD BECOME LESS
ACTIVE ON MONDAY, TAPERING OFF BY TUESDAY. THE DESERT SOUTHWEST
AND THE CENTRAL VALLEY OF CALIFORNIA WILL REMAIN HOT, WITH HIGHS
IN THE 110S AND 100S, RESPECTIVELY. ACROSS THE PACIFIC NORTHWEST,
HEAT IS FORECAST TO PEAK TODAY AND MONDAY, WITH RECORD-HIGH
TEMPERATURES REACHING INTO THE 80S AND AS HIGH AS THE MID-90S
BEFORE COOLING OFF ON TUESDAY. FARTHER EAST, A FEW RECORD HIGH
TEMPERATURES ARE POSSIBLE ACROSS THE MID-ATLANTIC AND NORTHEAST
BEFORE COOLER THAN NORMAL TEMPERATURES ARRIVE ON MONDAY. HOWEVER,
THE GULF COAST WILL REMAIN HOT AND HUMID AS THE FRONT BECOMES
NEARLY STATIONARY. FROM SUNDAY INTO MONDAY, THE SOUTH IS EXPECTED
TO SEE AN INCREASING CHANCE OF SHOWERS AND THUNDERSTORMS. A THREAT
OF HEAVY RAIN EMERGES TODAY ACROSS SOUTHWESTERN TEXAS, SHIFTING
EAST ON MONDAY ACROSS SOUTHERN TEXAS THROUGH THE LOWER MISSISSIPPI
VALLEY AS TROPICAL MOISTURE FROM A TROPICAL WAVE NEAR THE MEXICAN
EAST COAST BEGINS TO INTERACT WITH THE STATIONARY FRONT.
