VALID 00Z SUN APR 28 2024 - 00Z TUE APR 30 2024
...MORE ROUNDS OF EXCESSIVE RAINFALL AND SEVERE WEATHER EXPECTED
TO PUSH EASTWARD ACROSS THE SOUTHERN PLAINS TONIGHT REACHING INTO
LOWER MISSISSIPPI VALLEY ON MONDAY...
...SNOW OVER CENTRAL COLORADO GRADUALLY TAPERS OFF TONIGHT BUT
HIGH-ELEVATION SNOW IS FORECAST TO SPREAD INLAND FROM THE PACIFIC
NORTHWEST INTO THE NORTHERN ROCKIES ON MONDAY...
...CRITICAL FIRE WEATHER RISK OVER PORTIONS OF THE SOUTHERN HIGH
PLAINS...
...WARMER THAN AVERAGE TEMPERATURES SPREADS FROM MIDWEST INTO
MID-ATLANTIC ON SUNDAY WHILE WELL BELOW AVERAGE TEMPERATURES SHIFT
FROM THE FOUR CORNERS AND ROCKIES INTO THE NORTHERN PLAINS...
MORE ACTIVE AND UNSETTLED WEATHER IS FORECAST TO CONTINUE ACROSS
THE MID-SECTION OF THE COUNTRY THROUGH THE REMAINDER OF THE
WEEKEND INTO MONDAY. MULTIPLE DISTURBANCES EMBEDDED WITHIN A
SLOW-MOVING UPPER-LEVEL TROUGH RESPONSIBLE FOR THE ACTIVE WEATHER
ARE CURRENTLY DEVELOPING ANOTHER LOW PRESSURE SYSTEM OVER THE
CENTRAL PLAINS. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO ERUPT
IN THE WARM AND UNSTABLE AIR AHEAD OF THE LOW PRESSURE SYSTEM EAST
OF A DRY LINE FROM NORTHERN TEXAS THROUGH CENTRAL OKLAHOMA INTO
EASTERN KANSAS. A MODERATE RISK OF SEVERE WEATHER IS FORECAST
THROUGH TONIGHT PER THE STORM PREDICTION CENTER WITH THE
POSSIBILITY OF LARGE HAIL, DAMAGING WINDS AND MULTIPLE TORNADOES.
IN ADDITION TO THE SEVERE WEATHER, INTENSE RAINFALL RATES ARE
EXPECTED TO ACCOMPANY THESE THUNDERSTORMS AT TIMES, LEADING TO A
MODERATE TO LOCALLY HIGH POTENTIAL OF FLASH FLOODING TO OCCUR IN
THESE AREAS THROUGH TONIGHT. BY SUNDAY, THE MAIN AREA OF
THUNDERSTORMS WILL PUSH FARTHER EASTWARD TOWARD THE MID- AND LOWER
MISSISSIPPI VALLEY WITH A SLIGHTLY LOWER THREAT OF SEVERE WEATHER.
MEANWHILE, THE HEAVIEST RAINS SHOULD PUSH FARTHER SOUTHEAST INTO
THE ARKLATEX REGION AS THE TRAILING COLD FRONT ASSOCIATED WITH THE
LOW PRESSURE SYSTEM BEGINS TO WEAKEN. THE CENTER OF THE LOW IS
FORECAST TO TRACK NORTHEAST ACROSS THE CENTRAL PLAINS ON SUNDAY,
REACHING INTO THE UPPER MIDWEST ON MONDAY. STRONG TO LOCALLY
SEVERE THUNDERSTORMS CAN BE EXPECTED TO EXTEND NORTHEAST ACROSS
THESE AREAS INCLUDING THE MIDWEST AHEAD OF A WARM FRONT TO THE
EAST OF THE LOW PRESSURE CENTER. MEANWHILE, THE THREAT OF HEAVY
RAIN WILL PUSH FARTHER SOUTHEAST INTO THE LOWER TO MID-MISSISSIPPI
VALLEY AS THE COLD FRONT PUSHES EASTWARD.
MEANWHILE, SNOW ON THE BACKSIDE OF THE LOW PRESSURE SYSTEM IS
FORECAST TO GRADUALLY TAPER OFF TONIGHT OVER CENTRAL COLORADO, AND
SO WILL THE AREAS OF MIXED RAIN/SNOW EXTENDING INTO THE
FOUR-CORNERS AS THE SYSTEM MOVES FARTHER AWAY INTO THE CENTRAL
PLAINS. MEANWHILE, ANOTHER LOW PRESSURE SYSTEM WILL BEGIN TO MOVE
AWAY FROM THE GREAT LAKES INTO CANADA WITH SCATTERED SHOWERS
ENDING OVER THE UPPER GREAT LAKES BUT CONTINUING FROM THE LOWER
GREAT LAKES INTO NEW ENGLAND. STRONG SOUTHERLY FLOW BEHIND A HIGH
PRESSURE SYSTEM WILL BRING VERY WARM AIR NORTHWARD INTO THE EAST
COAST THROUGH THE NEXT COUPLE OF DAYS WITH HIGH TEMPERATURES
CLIMBING WELL INTO THE 80S TO POSSIBLY NEAR 90 DEGREES FOR THE
INTERIOR MID-ATLANTIC. THESE TEMPERATURES WILL BE IN CONTRAST TO
THE COOL TEMPERATURES EXPECTED FOR THE PACIFIC NORTHWEST BY MONDAY
AS THE NEXT UPPER-LEVEL TROUGH FROM THE PACIFIC IS FORECAST TO
PUSH INLAND. THIS TROUGH WILL BRING WIDESPREAD HIGH-ELEVATION
SNOW AND LOWER ELEVATION RAIN ACROSS THE PACIFIC NORTHWEST TOWARD
THE NORTHERN ROCKIES ON MONDAY WITH INCREASINGLY WINDY CONDITIONS
AS A LOW PRESSURE SYSTEM BEGINS TO DEVELOP OVER THE NORTHERN HIGH
PLAINS INTO SOUTHERN CANADA. MEANWHILE, DRY AND WARM WINDS
SINKING DOWN THE SOUTHERN ROCKIES WILL CONTINUE TO KEEP A CRITICAL
FIRE WEATHER RISK OVER THE SOUTHERN HIGH PLAINS.
