...SHOWERS AND THUNDERSTORMS NEAR A STATIONARY FRONT COULD BRING
HEAVY RAIN ACROSS SOUTHEASTERN FLORIDA LATER ON SUNDAY...
...UNSETTLED WEATHER WILL SPREAD INTO NORTHERN CALIFORNIA, THE
GREAT BASIN, AND THE NORTHERN TO CENTRAL ROCKIES TO START THE NEW
WORK WEEK...
...ANOTHER NIGHT OF FROST/FREEZE EXPECTED OVER THE EAST-CENTRAL
U.S. BUT UNSEASONABLE WARMTH FOR THE PACIFIC NORTHWEST FOLLOWED BY
COLD AIR INTRUSION FOR THE NORTHERN U.S. ON MONDAY...
A COLD FRONT SLIDING FARTHER SOUTH INTO THE GULF AND OFF THE COAST
OF SOUTHEASTERN U.S. WILL CONTINUE TO SPREAD ORGANIZED SHOWERS AND
THUNDERSTORMS ACROSS THE FLORIDA PENINSULA THROUGH TONIGHT. SOME
OF THE THUNDERSTORMS COULD CONTAIN SEVERE WEATHER ACROSS THE
CENTRAL PORTION OF THE FLORIDA PENINSULA SATURDAY AFTERNOON INTO
THE EVENING. THE FRONT IS FORECAST TO SLOW DOWN ON SUNDAY AND
BECOME NEARLY STATIONARY BY SUNDAY EVENING. THE SHOWERS AND
THUNDERSTORMS WILL BEGIN TO LINGER ACROSS SOUTHERN FLORIDA, AND IT
IS POSSIBLE FOR SOUTHEASTERN FLORIDA TO RECEIVE SOME HEAVY
RAINFALL FROM SOME OF THE SLOW-MOVING OR BACK-BUILDING
THUNDERSTORMS LATER ON SUNDAY OR SUNDAY NIGHT. SOME SHOWERS ARE
EXPECTED TO LINGER INTO MONDAY FOR SOUTH FLORIDA BUT DRIER AIR
FROM THE HIGH PRESSURE RIDGE MOVING OFF THE EAST COAST SHOULD KEEP
THE SHOWERS RELATIVELY LIGHT ON MONDAY.
AS THE AFOREMENTIONED COLD FRONT MOVES OFF THE EAST COAST TONIGHT,
A LOW-PRESSURE SYSTEM IS FORECAST TO RAPIDLY INTENSIFY OVER THE
GULF STREAM AND TRACK JUST OFF THE COAST OF NEW ENGLAND ON SUNDAY.
WHILE THE CORE OF THE SYSTEM IS EXPECTED TO REMAIN OFFSHORE, A
ROUND OF RAIN IS FORECAST FOR SOUTHEASTERN NEW ENGLAND WITH GUSTY
WINDS TONIGHT, FOLLOWED BY EASTERN MAINE DURING THE DAY ON SUNDAY.
ISOLATED SNOW SHOWERS COULD BRUSH THE HIGHER ELEVATIONS OF
INTERIOR NEW ENGLAND ON SUNDAY BEFORE SHOWERS ASSOCIATED WITH A
CLIPPER SYSTEM PASSING NORTH OF THE GREAT LAKES MOVE INTO THE
INTERIOR NORTHEAST ON MONDAY.
MEANWHILE, AN UPPER-LEVEL TROUGH OFF THE WEST COAST IS FORECAST TO
EVOLVE INTO A CUT-OFF LOW AND BECOME SLOW-MOVING AS IT BECOMES
DISCONNECTED FROM THE MAIN JET STREAM. A FRONTAL BOUNDARY WILL BE
SLOW TO MOVE THROUGH THE SOUTHWEST FOR THE REMAINDER OF THE
WEEKEND INTO EARLY NEXT WEEK. NORTHERN CALIFORNIA, SIERRA NEVADA
AND INTO THE GREAT BASIN WILL SEE UNSETTLED WEATHER SPREADING INTO
THE REGION THROUGH MONDAY. MEANWHILE, COLD AIR FROM CENTRAL
CANADA IS BEGINNING TO SURGE SOUTHWARD AND IS FORECAST TO SPREAD
INTO THE NORTHERN U.S. ON MONDAY WITH FALLING TEMPERATURES AND
INCREASING CHANCE OF SHOWERS FOR THE NORTHERN TO CENTRAL ROCKIES.
IN THE EASTERN HALF OF THE COUNTRY, ANOTHER NIGHT OF FROST/FREEZE
IS EXPECTED OVER THE EAST-CENTRAL U.S. BEFORE A QUICK WARM-UP INTO
THE 70'S IS FORECAST ON MONDAY. IN THE SOUTHEAST, TEMPERATURES
ARE ANTICIPATED TO STAY IN THE LOW TO MID-60S, WHILE THE GREAT
LAKES REGION SHOULD SEE HIGHS RECOVERING INTO THE 50S ON SUNDAY.
MEANWHILE, IN THE NORTHWEST, TEMPERATURES WILL REMAIN WELL ABOVE
AVERAGE. PARTS OF WASHINGTON AND OREGON COULD SEE HIGHS
APPROACHING AND POTENTIALLY EXCEEDING 90 DEGREES ON SUNDAY. A
COOLDOWN IS THEN SET TO BEGIN FOR MOST OF THE WEST AS THE
AFOREMENTIONED UPPER LOW/TROUGH MOVES INLAND, WITH THE EXCEPTION
OF THE PACIFIC NORTHWEST, WHICH WILL REMAIN UNSEASONABLY WARM
THROUGH EARLY NEXT WEEK.
