...MULTIPLE ROUNDS OF HEAVY RAIN AND THUNDERSTORMS EXPECTED FOR
THE CENTRAL U.S. THROUGH MONDAY...
..SEVERE WEATHER LIKELY FOR PORTIONS OF THE DAKOTAS ON SUNDAY
...HOT WEATHER ACROSS THE PLAINS AND FIRE WEATHER CONCERNS
CONTINUE FOR THE WEST...
AN AMPLIFIED UPPER LEVEL FLOW PATTERN WILL BE IN PLACE ACROSS THE
CONTINENTAL U.S. THROUGH MONDAY, WITH A UPPER TROUGH SITUATED
ACROSS THE PACIFIC NORTHWEST AND NORTHERN ROCKIES, AND AN UPPER
RIDGE AXIS ACROSS THE PLAINS AND MIDWEST. AT THE INTERFACE OF
THESE FEATURES WILL BE AN ORGANIZED STORM SYSTEM THAT WILL AFFECT
THE NORTHERN PLAINS THROUGH SUNDAY NIGHT. KINEMATIC AND
INSTABILITY PARAMETERS ARE FAVORABLE FOR THE DEVELOPMENT OF SEVERE
THUNDERSTORMS ACROSS THE WESTERN DAKOTAS ON SUNDAY AND INTO SUNDAY
NIGHT, WITH AN ENHANCED RISK OF SEVERE STORMS IN THE LATEST SPC
CONVECTIVE OUTLOOK. THERE IS ALSO A MARGINAL RISK OF EXCESSIVE
RAINFALL FOR THIS SAME GENERAL AREA, BUT THE OVERALL PROGRESSIVE
NATURE OF THE STORMS THAT DEVELOP SHOULD HELP TO MITIGATE THE
OVERALL FLOODING POTENTIAL.
SPEAKING OF RAINFALL, THE GREATEST CONCENTRATION OF SLOW MOVING
STORMS WITH HEAVY DOWNPOURS IS FORECAST TO BE ACROSS EASTERN
PORTIONS OF THE CENTRAL PLAINS ON SUNDAY, AND EXTENDING TO THE
WESTERN OHIO VALLEY BY MONDAY, WHERE THE POTENTIAL CURRENTLY
EXISTS FOR 1 TO 3 INCHES OF RAINFALL THROUGH MONDAY NIGHT. THERE
IS A SLIGHT RISK OF EXCESSIVE RAINFALL FROM WPC TO ACCOUNT FOR
THIS. PORTIONS OF THE CENTRAL GULF COAST COULD ALSO GET SOME SLOW
MOVING STORMS WITH LOCALLY HIGH RAINFALL RATES. LIGHTER RAINFALL
IS LIKELY FOR PORTIONS OF THE NORTHEAST U.S., AND ALSO FOR WESTERN
WASHINGTON AND OREGON WITH ONSHORE FLOW INCREASING ON MONDAY AHEAD
OF THE NEXT PACIFIC COLD FRONT.
IN TERMS OF TEMPERATURES, IT WILL BE QUITE WARM FROM THE EASTERN
FOOTHILLS OF THE ROCKIES TO THE DAKOTAS AND INTO THE UPPER MIDWEST
ON SUNDAY, WITH HIGHS RUNNING 10-20 DEGREES ABOVE AVERAGE IN MANY
CASES. IT REMAINS HOT ACROSS THE CENTRAL PLAINS GOING INTO MONDAY
AS WELL, BUT RELIEF ARRIVES ACROSS THE DAKOTAS WITH A COLD FRONT
PASSING THOUGH THE REGION. FOR THE EAST COAST, A SLIGHT COOL DOWN
ALONG WITH LOWER HUMIDITY IS EXPECTED ACROSS THE MID-ATLANTIC AND
THE NORTHEAST TO START THE WORK WEEK AS A MODERATELY STRONG COLD
FRONT PASSES THROUGH THE REGION. ACROSS THE INTERMOUNTAIN WEST,
FIRE WEATHER CONCERNS WILL CONTINUE THROUGH THE WEEKEND AND INTO
MONDAY, WITH HOT AND DRY CONDITIONS ALONG WITH GUSTY WINDS
CREATING A FAVORABLE ENVIRONMENT FOR POTENTIAL WILD FIRES.
