VALID 12Z SAT APR 20 2024 - 12Z MON APR 22 2024
...HEAVY RAIN AND SCATTERED INSTANCES OF FLASH FLOODING POSSIBLE
ACROSS THE SOUTHERN PLAINS AND LOWER MISSISSIPPI VALLEY TODAY...
...LIGHT SNOW CONTINUES ACROSS PARTS OF THE CENTRAL ROCKIES AND
CENTRAL HIGH PLAINS...
...BELOW AVERAGE TEMPERATURES FOR MUCH OF THE NATION EAST OF THE
ROCKIES THIS WEEKEND BEFORE SPRING WARMTH RETURNS TO THE PLAINS ON
MONDAY...
A LINGERING QUASI-STATIONARY FRONT DRAPED ACROSS THE SOUTHEAST,
GULF COAST STATES, AND SOUTHERN PLAINS WILL BE THE FOCUS FOR
NUMEROUS SHOWERS AND THUNDERSTORMS THIS WEEKEND. THE GREATEST
IMPACTS ASSOCIATED WITH THIS SYSTEM ARE EXPECTED TO OCCUR TODAY AS
HEAVY RAIN COULD LEAD TO SCATTERED FLASH FLOODING ISSUES FROM
TEXAS TO MISSISSIPPI. MULTIPLE ROUNDS OF POTENTIALLY INTENSE
RAINFALL DEVELOPING OVER SATURATED TERRAIN HAS PROMPTED A SLIGHT
RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL THROUGH TONIGHT. THIS AREA
INCLUDES MUCH OF CENTRAL AND EASTERN TEXAS, NORTHERN LOUISIANA,
SOUTHERN ARKANSAS, AND CENTRAL MISSISSIPPI. A FEW ISOLATED STORMS
COULD ALSO CONTAIN DAMAGING WIND GUSTS AND HAIL THROUGHOUT
CENTRAL/SOUTHERN TEXAS AND THE SOUTHEAST. THE GREATEST COVERAGE OF
SHOWERS AND THUNDERSTORMS ARE EXPECTED TO PROGRESS EASTWARD
TONIGHT AND EVENTUALLY CONFINE TO THE CENTRAL GULF COAST AND
SOUTHEAST ON SUNDAY, WITH LESSENING CHANCES FOR FLASH FLOODING AND
SEVERE THUNDERSTORMS.
LIGHT PRECIPITATION CHANCES ARE ALSO FORECAST TO CONTINUE ACROSS
OTHER PARTS OF THE NATION THROUGH MONDAY. LIGHT SNOW WILL LINGER
THROUGHOUT PARTS OF COLORADO TODAY, WHERE A FEW ADDITIONAL INCHES
OF ACCUMULATING SNOWFALL ARE EXPECTED ALONG THE FRONT RANGE.
WINTER WEATHER ADVISORIES REMAIN IN EFFECT. MEANWHILE, AN EXITING
COLD FRONT TODAY FOLLOWED BY A STRONGER COLD FRONT ON SUNDAY NIGHT
WILL LEAD TO RAIN AND SNOW SHOWERS TRAVERSING NEW ENGLAND. LASTLY,
THE NEXT FRONTAL SYSTEM TO IMPACT THE PACIFIC NORTHWEST WILL
RAPIDLY SPREAD SHOWERS THROUGHOUT THE REGION TONIGHT BEFORE
SWIFTLY PUSHING RAIN CHANCES INTO THE NORTHERN PLAINS AND UPPER
MIDWEST ON MONDAY.
TEMPERATURES ARE ANTICIPATED TO REMAIN BELOW AVERAGE FOR MUCH OF
THE COUNTRY BEHIND THE COLD FRONT EXTENDING FROM THE SOUTHEAST TO
THE SOUTHERN PLAINS. THIS LEAVES THE WEST, SOUTHWEST, AND
SOUTHEAST AS THE WARM SPOTS THIS WEEKEND WITH HIGHS INTO THE 70S
AND 80S. AS TEMPERATURES MODERATE ON MONDAY AND RETURN FLOW ENTERS
THE CENTRAL U.S., BELOW NORMAL TEMPERATURES ARE EXPECTED TO ERODE
AS HIGHS INTO THE 70S SURGE INTO THE CENTRAL PLAINS, WITH COOLER
WEATHER REMAINING ACROSS THE NORTHEAST. ADDITIONALLY, LOWS INTO
THE 30S OVER THE NEXT FEW MORNINGS COULD LEAD TO FROST/FREEZE
CONCERNS FOR LOCATIONS ALREADY IN THE GROWING SEASON FROM THE
MIDWEST TO THE UPPER OHIO VALLEY.
