VALID 12Z FRI APR 26 2024 - 12Z SUN APR 28 2024
...AN ACTIVE WEATHER PATTERN FOR MUCH OF THE PLAINS INTO THE MID
TO UPPER MISSISSIPPI VALLEY REGIONS...
...THUNDERSTORMS TO BRING HEAVY RAIN, LOCALIZED FLASH FLOODING AND
SEVERE WEATHER TO PORTIONS OF THE PLAINS...
...AN ELEVATED TO CRITICAL FIRE WEATHER THREAT ACROSS THE SOUTHERN
HIGH PLAINS...
..COOLER THAN AVERAGE TEMPERATURES EXPECTED FROM THE ROCKIES TO
THE WEST COAST AND FROM THE MID-ATLANTIC TO THE NORTHEAST, WHILE
MUCH ABOVE AVERAGE TEMPERATURES SPREAD FROM THE SOUTHERN PLAINS TO
THE GREAT LAKES...
A DYNAMIC WEATHER SYSTEM IS POISED TO BRING SIGNIFICANT WEATHER
IMPACTS ACROSS THE PLAINS EXTENDING INTO THE MID-TO-UPPER
MISSISSIPPI VALLEY REGIONS THIS WEEKEND. THIS SYSTEM WILL USHER IN
A VARIETY OF WEATHER PHENOMENA INCLUDING THUNDERSTORMS, HEAVY
RAINFALL, AND EVEN SEVERE WEATHER CONDITIONS. THUNDERSTORM
ACTIVITY IS FORECASTED TO INTENSIFY ACROSS PORTIONS OF THE PLAINS,
PARTICULARLY IN AREAS EXTENDING FROM THE SOUTHERN PLAINS TO THE
GREAT LAKES. THESE STORMS ARE LIKELY TO BRING HEAVY RAINFALL,
INCREASING THE RISK OF LOCALIZED FLASH FLOODING IN LOW-LYING AND
URBAN AREAS. THERE'S A SLIGHT RISK (AT LEAST 15%) OF EXCESSIVE
RAINFALL LEADING TO FLASH FLOODING OVER PORTIONS OF EASTERN
OKLAHOMA AND NORTHEASTERN TEXAS INTO WESTERN ARKANSAS AND SOUTHERN
MISSOURI TODAY. ANOTHER SYSTEM EMERGING FROM THE ROCKIES WILL
BRING THE FOCUS FOR HEAVY RAINFALL AND SEVERE STORMS BACK OVER THE
SOUTHERN PLAINS ON SATURDAY. THERE'S A MODERATE RISK (AT LEAST
40%) OF EXCESSIVE RAINFALL OVER CENTRAL TO NORTHEASTERN OKLAHOMA
ON SATURDAY. FURTHERMORE, SOME OF THESE STORMS MAY TURN SEVERE,
WITH THE POTENTIAL FOR DAMAGING WINDS, LARGE HAIL, AND ISOLATED
TORNADOES. TO THAT END, THE STORM PREDICTION CENTER ISSUED AN
ENHANCED RISK (LEVEL 3/5) OF SEVERE THUNDERSTORMS OVER PORTIONS OF
EASTERN NEBRASKA, NORTHEASTERN KANSAS, NORTHWESTERN MISSOURI AND
SOUTHWESTERN IOWA TODAY ANOTHER ENHANCED RISK AREA WAS ISSUED
ACROSS PARTS OF SOUTHERN IOWA, EASTERN/CENTRAL KANSAS,
SOUTHEASTERN NEBRASKA, NORTHWESTERN MISSOURI, CENTRAL OKLAHOMA AND
NORTH-CENTRAL TEXAS FOR SATURDAY AS ANOTHER SYSTEM SPAWNS ANOTHER
ROUND OF STORMS FOR THE CENTRAL U.S..
WHILE THUNDERSTORMS POSE A THREAT TO SOME AREAS, THE SOUTHERN HIGH
PLAINS FACE AN ELEVATED TO CRITICAL FIRE WEATHER THREAT THROUGH
THIS WEEKEND. DRY AND GUSTY CONDITIONS, COUPLED WITH LOW RELATIVE
HUMIDITY LEVELS, WILL CREATE FAVORABLE CONDITIONS FOR THE RAPID
SPREAD OF WILDFIRES. OUTDOOR BURNING IS STRONGLY DISCOURAGED, AND
RESIDENTS SHOULD EXERCISE EXTREME CAUTION TO PREVENT THE IGNITION
OF FIRES. A COOLER AIR MASS WILL SETTLE OVER REGIONS STRETCHING
FROM THE ROCKIES TO THE WEST COAST AND FROM THE MID-ATLANTIC TO
THE NORTHEAST. TEMPERATURES ARE FORECASTED TO REMAIN BELOW AVERAGE
FOR THIS TIME OF YEAR. CONVERSELY, A SWATH OF MUCH ABOVE AVERAGE
TEMPERATURES IS EXPECTED TO ENCOMPASS AREAS FROM THE SOUTHERN
PLAINS TO THE GREAT LAKES. DAYTIME HIGHS WILL SOAR, POTENTIALLY
REACHING UNSEASONABLY WARM LEVELS. MEANWHILE, UNSETTLED WEATHER,
INCLUDING RAIN/SNOW SHOWERS AND SCATTERED TO ISOLATED
THUNDERSTORMS ARE EXPECTED TO SPREAD ACROSS MUCH OF THE WEST
THROUGH SATURDAY.
