...STRONG THUNDERSTORMS AND LOCALLY HEAVY RAIN EXPECTED TO MOVE
ACROSS MUCH OF THE EASTERN U.S. THROUGH TONIGHT, THEN ACROSS THE
NORTHEAST ON MONDAY...
...TURNING COLDER AND UNSETTLED ACROSS THE PACIFIC NORTHWEST AND
NORTHERN ROCKIES WITH COASTAL AND VALLEY RAIN ALONG WITH MOUNTAIN
SNOW AND GUSTY WINDS...
...A ROUND OF RAIN/THUNDERSTORMS THEN WINDY AND COLDER WEATHER
ACROSS THE NORTHERN PLAINS WILL BE CONTRASTED WITH TEMPERATURES IN
THE 90S ACROSS THE SOUTHERN PLAINS ON MONDAY...
AN INCREASINGLY ACTIVE WEATHER PATTERN IS IN PROGRESS ACROSS THE
U.S. MAINLAND THROUGH THE NEXT COUPLE OF DAYS WITH THE EMERGENCE
OF LA NINA. THIS ACTIVE WEATHER PATTERN WILL BEGIN WITH A RAPIDLY
INTENSIFYING LOW PRESSURE SYSTEM FORECAST TO TRACK SWIFTLY ACROSS
THE MIDWEST AND THE GREAT LAKES TODAY. THE VIGOROUS DYNAMICS
ASSOCIATED WITH A POTENT COLD FRONT TRAILING SOUTH FROM THE
CYCLONE CENTER IS FORECAST TO BRING A SLIGHT RISK OF SEVERE
WEATHER ACROSS MUCH OF THE MID TO LOWER MISSISSIPPI VALLEY THROUGH
EARLY THIS MORNING. THE COLD FRONT WILL CONTINUE TO PUSH EASTWARD
THROUGH THE EASTERN U.S. FOR THE REST OF TODAY BEFORE MOVING OFF
THE EAST COAST TONIGHT. THE RELATIVELY FAST FORWARD MOTION OF THE
COLD FRONT WILL HELP LIMIT THE TOTAL RAINFALL AMOUNTS. HOWEVER, A
SQUALL LINE JUST AHEAD OF THE COLD FRONT COULD BRING A BRIEF
PERIOD OF STRONG THUNDERSTORMS WITH HEAVY DOWNPOURS ALONG WITH
VERY GUSTY WINDS. BY MONDAY, THE MOST ACTIVE WEATHER WILL LIKELY
BE FOUND ACROSS THE NORTHEAST, PARTICULARLY NEW ENGLAND, WHERE
STRONG THUNDERSTORMS AND LOCALLY HEAVY RAIN COULD BE SWEEPING
ACROSS AS A NEW LOW PRESSURE SYSTEM BEGINS TO DEVELOP. THIS
SYSTEM WILL SLOW DOWN AND PROVIDE RAIN ACROSS NORTHERN NEW ENGLAND
AS WELL AS WINDY CONDITIONS ACROSS MUCH OF THE NORTHEAST.
BEHIND THE RAPIDLY INTENSIFYING CYCLONE IN THE EAST, STRONG AND
GUSTY NORTHWESTERLY WINDS WILL MAKE FOR A BREEZY DAY TODAY ACROSS
THE MID-SECTION OF THE COUNTRY AS A COLDER AIR MASS FROM CANADA
FILTERS INTO THE REGION. HOWEVER, A RAPID WARM-UP IS FORECAST FOR
THE HIGH PLAINS TODAY, SPREADING INTO THE SOUTHERN PLAINS BY
MONDAY. THIS WARM-UP WILL BE IN ADVANCE OF ANOTHER RAPIDLY
DEVELOPING LOW PRESSURE SYSTEM THAT WILL SWEEP ACROSS THE PACIFIC
NORTHWEST TODAY FOLLOWED BY THE NORTHERN PLAINS AND UPPER MIDWEST
ON MONDAY. THIS SYSTEM WILL KEEP UNSETTLED WEATHER ACROSS THE
PACIFIC NORTHWEST WITH COASTAL AND VALLEY RAINS ALONG WITH SNOW IN
THE HIGHER ELEVATIONS THROUGH TONIGHT. MEANWHILE, MOUNTAIN SNOW
IS EXPECTED TO PUSH FARTHER INLAND ACROSS IDAHO AND THEN THE
NORTHERN ROCKIES TONIGHT INTO MONDAY ALONG WITH GUSTY WINDS. THE
LOW PRESSURE SYSTEM WILL CONTINUE TO DEVELOP WHILE MOVING QUICKLY
ACROSS THE NORTHERN PLAINS ON MONDAY, BRINGING A PERIOD OF RAIN
FOLLOWED BY COLDER AND WINDY CONDITIONS ESPECIALLY ACROSS THE
NORTHERN HIGH PLAINS MONDAY INTO TUESDAY MORNING. TO THE SOUTH OF
THIS SYSTEM, BRISK WINDS DESCENDING THE SOUTHERN ROCKIES WILL MAKE
FOR A VERY WARM AFTERNOON ACROSS THE SOUTHERN PLAINS WHERE HIGHS
ARE FORECAST TO REACH WELL INTO THE 90S, WHICH WILL BE HIGH ENOUGH
TO CHALLENGE SOME DAILY RECORDS. MEANWHILE, THE SOUTHWEST AND THE
FOUR CORNERS WILL REMAIN DRY WITH A GRADUAL WARMING TREND THROUGH
EARLY NEXT WEEK. ACROSS THE SUNSHINE STATE, SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO MOVE ACROSS FROM NORTHWEST TO
SOUTHEAST THROUGH THE NEXT COUPLE OF DAYS AS THE COLD FRONT
ASSOCIATED WITH THE FORMER INTENSIFYING LOW PRESSURE SYSTEM SWEEPS
ACROSS THE STATE.
