...STORMY WEATHER CONTINUES ACROSS PARTS OF THE CENTRAL PLAINS AND
ALONG THE GULF COAST THROUGH SOUTHERN TEXAS, WITH LOCALLY HEAVY
RAIN AND FLASH FLOODING POSSIBLE...
...COOLER CONDITIONS PERSIST ACROSS MUCH OF THE EASTERN AND
CENTRAL U.S., WHILE A STRONG COLD FRONT BRINGS A NOTABLY COLDER
AIRMASS INTO THE NORTHERN PLAINS AND MIDWEST MIDWEEK...
...HEAT INTENSIFIES IN THE NORTHWEST, WITH RECORD-BREAKING HIGHS
LIKELY ACROSS THE NORTHERN INTERMOUNTAIN WEST...
SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP THIS EVENING
INTO THE OVERNIGHT HOURS ALONG AND NORTH OF A SLOW-MOVING FRONTAL
BOUNDARY STRETCHING FROM THE GULF COAST BACK THROUGH SOUTHERN
TEXAS. WITH ABUNDANT MOISTURE IN PLACE, STORMS MAY PRODUCE HEAVY
RAINFALL RATES LEADING TO LOCALIZED FLOODING, WITH ISOLATED TO
SCATTERED FLASH FLOODING POSSIBLE. ALTHOUGH UNSETTLED CONDITIONS
ARE EXPECTED TO PERSIST ACROSS TEXAS AND THE GULF COAST THROUGH
TOMORROW, THE THREAT FOR HEAVY RAINFALL AND FLOODING SHOULD
GRADUALLY DIMINISH AS THE FRONT SHIFTS FARTHER SOUTH AND DRIER AIR
PRESSES INTO THE REGION.
FARTHER NORTH, A SLOW-MOVING DISTURBANCE WILL TRIGGER SHOWERS AND
STORMS ACROSS PORTIONS OF THE CENTRAL PLAINS, EASTERN OKLAHOMA,
AND THE LOWER MISSOURI VALLEY LATE TODAY INTO TOMORROW. UNSETTLED
WEATHER WILL LINGER INTO EARLY TUESDAY BEFORE THE SYSTEM
ACCELERATES EASTWARD, SPREADING SHOWERS AND THUNDERSTORMS ACROSS
THE LOWER MISSISSIPPI AND TENNESSEE VALLEYS BY LATE IN THE DAY. IN
ADDITION TO THE CLOUDS AND RAIN, DAYTIME TEMPERATURES WILL REMAIN
10â€15 DEGREES BELOW NORMAL ACROSS PARTS OF THE CENTRAL PLAINS
AND LOWER MISSOURI VALLEY.
ACROSS THE EASTERN U.S., TEMPERATURES ARE FORECAST TO REMAIN
SEASONAL TO BELOW AVERAGE INTO MIDWEEK. IN CONTRAST, ABOVE-NORMAL
WARMTH WILL PERSIST ALONG THE CALIFORNIA COAST AND ACROSS THE
NORTHWEST. WELL-ABOVE-NORMAL TEMPERATURES WILL EXPAND ACROSS THE
NORTHWEST INTO MIDWEEK, WITH RECORD-BREAKING HIGHS EXPECTED ACROSS
PARTS OF EASTERN WASHINGTON AND NORTHERN IDAHO BEGINNING TUESDAY.
WHILE THE NORTHWEST REMAINS HOT AND DRY, MONSOON MOISTURE WILL
PUSH NORTHWARD FROM THE SOUTHWEST ON TUESDAY, BRINGING AN
INCREASING CHANCE FOR SHOWERS AND THUNDERSTORMS ACROSS NEVADA AND
INTERIOR CALIFORNIA.
FINALLY, A STRONG COLD FRONT DROPPING SOUTH OUT OF CANADA WILL
SWEEP INTO THE NORTHERN PLAINS AND UPPER MIDWEST ON TUESDAY. THIS
SYSTEM WILL BRING A CHANCE FOR SHOWERS AND STORMS, FOLLOWED BY A
NOTABLY COLDER AIRMASS SPREADING ACROSS THE REGION.
