359 AM EDT SAT NOV 02 2024
VALID 12Z SAT NOV 02 2024 - 12Z MON NOV 04 2024
...FREQUENT ROUNDS OF HEAVY RAIN AND SEVERE WEATHER EXPECTED
ACROSS THE CENTRAL AND SOUTHERN PLAINS THROUGHOUT THIS WEEKEND AND
INTO MONDAY...
...MOUNTAIN SNOW WILL SPREAD FROM THE PACIFIC NORTHWEST INTO MUCH
OF THE INTERMOUNTAIN WEST OVER THE NEXT COUPLE OF DAYS...
...MUCH ABOVE AVERAGE TEMPERATURES EXPECTED ACROSS LARGE PORTIONS
OF THE CENTRAL TO EASTERN U.S. WITH NO RAIN IN SIGHT ALONG THE
EAST COAST...
AN UPPER-LEVEL TROUGH DIGGING INTO THE WESTERN U.S. WILL BE
PUSHING AGAINST A RIDGE OF HIGH PRESSURE BUILDING ACROSS THE
EASTERN U.S. THIS WILL RESULT AN AMPLIFYING WEATHER PATTERN
ACROSS THE MAINLAND U.S. THROUGH THIS WEEKEND, WITH THE MOST
VIGOROUS BATTLE ZONE OCCURRING OVER THE SOUTH-CENTRAL U.S. AS
MOUNTAIN SNOW BEING USHERED INTO THE WESTERN U.S. WITH THE ARRIVAL
OF THE UPPER TROUGH, A LARGE HIGH PRESSURE SYSTEM WILL QUICKLY
BUILD ACROSS THE NORTHEASTERN QUADRANT OF THE COUNTRY TODAY. THIS
HIGH PRESSURE SYSTEM WILL SETTLE AND EXPAND ACROSS THE EASTERN
TWO-THIRDS OF THE COUNTRY THIS WEEKEND, BRINGING COOLER AIR INTO
THE NORTHEAST. IN CONTRAST, WIDESPREAD ABOVE AVERAGE TEMPERATURES
ARE EXPECTED FROM THE PLAINS EASTWARD WITH NO RAIN IN SIGHT ALONG
THE EAST COAST INTO THE FIRST FEW DAYS OF NOVEMBER.
ATTENTION WILL THEN FOCUS ACROSS THE MID-SECTION OF THE COUNTRY
WHERE A RATHER SIGNIFICANT HEAVY RAIN AND SEVERE WEATHER EVENT IS
CURRENTLY DEVELOPING. AS MOIST AIR FROM THE GULF OF MEXICO
RETURNS AND STREAMS NORTHWARD INTO THE SOUTHERN PLAINS BEHIND THE
HIGH PRESSURE SYSTEM, THE DEEPENING UPPER-LEVEL TROUGH MOVING INTO
THE WESTERN U.S. WILL SPREAD MORE MOUNTAIN SNOW ACROSS THE
INTERMOUNTAIN WEST THIS WEEKEND. SOUTHWESTERLY FLOW AHEAD OF THE
TROUGH WILL THEN INTERACT WITH THE RETURNING GULF MOISTURE AND
LIFT THE MOISTURE OVER A WARM FRONT ACROSS THE CENTRAL AND
SOUTHERN PLAINS. HEAVY RAIN ASSOCIATED WITH ORGANIZED
THUNDERSTORMS ARE CURRENTLY ERUPTING OVER THE SOUTHERN HIGH
PLAINS. THE THUNDERSTORMS AND HEAVY RAIN WILL THEN EXPAND
NORTHEASTWARD INTO THE CENTRAL PLAINS THROUGH THE WEEKEND. A FEW
INCHES OF HEAVY RAIN WITH LOCALLY HIGHER AMOUNTS IS FORECAST
ACROSS THE SOUTH-CENTRAL U.S., WITH THE HEAVIEST RAINFALL EXPECTED
ACROSS CENTRAL OKLAHOMA. SIMILAR TO MANY AREAS OF THE LOWER 48,
THIS REGION IS EXPERIENCING MODERATE TO EXTREME DROUGHT
CONDITIONS. WHILE THIS HEAVY RAIN EVENT WILL HELP ALLEVIATE THE
DROUGHT, THE EXPECTED HIGH RAINFALL RATES WILL BRING AN INCREASING
THREAT OF FLASH FLOODING. WPC CURRENTLY HAS A MODERATE RISK OF
FLASH FLOODING IN PLACE FROM CENTRAL OKLAHOMA TO SOUTHEASTERN
KANSAS AND INTO SOUTHWESTERN MISSOURI FROM SUNDAY INTO EARLY
MONDAY. PLEASE STAY ABREAST OF THE LATEST FORECAST UPDATES ON
THIS UPCOMING HEAVY RAIN/SEVERE WEATHER EVENT ACROSS THE CENTRAL
TO SOUTHERN PLAINS. THIS SYSTEM WILL ALSO SPREAD SOME LIGHT TO
MODERATE RAIN FARTHER NORTH ACROSS THE NORTHERN PLAINS, AND
MODERATE TO LOCALLY HEAVY RAIN TOWARD THE UPPER MIDWEST ON SUNDAY
INTO EARLY MONDAY.
