...IMELDA ACCELERATING EASTWARD OUT TO SEA; SWELLS, HIGH SURF, AND
DANGEROUS RIP CURRENTS CONTINUE ALONG MUCH OF THE EAST COAST THE
NEXT SEVERAL DAYS...
...COOL AND UNSETTLED WEATHER PERSISTS ACROSS PORTIONS OF THE
GREAT BASIN AND PACIFIC NORTHWEST...
...UNSEASONABLY HOT TEMPERATURES CONTINUE FOR MUCH OF THE PLAINS
AND MIDWEST THROUGH THE REMAINDER OF THE WEEK...
AS EXPECTED, IMELDA HAS MADE ITS TURN TO THE EAST-NORTHEAST IN THE
SOUTHWEST ATLANTIC OCEAN AND IS NOW ACCELERATING FARTHER OUT TO
SEA. IN ITS WAKE, STRONG HIGH PRESSURE WILL DESCEND SOUTHWARD FROM
CANADA AND SETTLE OVER THE NORTHEAST AND MID-ATLANTIC BY THE END
OF THE WEEK. THIS BUBBLE OF HIGH PRESSURE WILL LEAD TO MAINLY DRY
WEATHER AND MUCH MORE FALL-LIKE TEMPERATURES FOR MOST OF THE
EASTERN U.S. HEADING INTO THE WEEKEND. HOWEVER, A PROLONGED
STRETCH OF STRONG, EASTERLY, ONSHORE FLOW ON THE SOUTHERN
PERIPHERY OF THE DOME OF HIGH PRESSURE COMBINED WITH THE INCREASED
WAVE ACTION GENERATED BY BOTH IMELDA AND HUMBERTO WILL ALSO LEAD
TO SWELLS, HIGH SURF, AND DANGEROUS RIP CURRENTS ALONG MUCH OF THE
EAST COAST THE NEXT SEVERAL DAYS. ADDITIONALLY, THE MOIST ONSHORE
FLOW WILL ALSO MAKE AN EXCEPTION TO THE MAINLY DRY WEATHER ACROSS
THE SOUTHEAST U.S. AS SEVERAL ROUNDS OF SHOWERS AND THUNDERSTORMS
ARE LIKELY FOR COASTAL AREAS OF THE CAROLINAS, GEORGIA, AND
ESPECIALLY THE EAST COAST OF FLORIDA. IN FACT, THE REPEATING
NATURE OF THIS ACTIVITY COULD LEAD TO ISOLATED FLASH FLOODING
CONCERNS THROUGH THE REST OF THE WEEK AND FOR MUCH OF THE WEEKEND
AS WELL.
UNSETTLED AND UNSEASONABLY COOL WEATHER WILL CONTINUE FOR PARTS OF
THE PACIFIC NORTHWEST, GREAT BASIN, AND INTERMOUNTAIN WEST THE
NEXT FEW DAYS AS PERSISTENT UPPER-LEVEL TROUGHING AND A COUPLE
FRONTAL SYSTEMS PASS THROUGH THE REGION. MOIST PACIFIC FLOW
COMBINED WITH A SERIES OF SURFACE FRONTS AND UPPER-LEVEL
DISTURBANCES WILL BRING PERIODIC WAVES OF SHOWERS AND
THUNDERSTORMS THROUGH THE END OF THE WEEK. EVEN A LITTLE BIT OF
SNOW COULD MIX IN WITH THE RAIN IN THE HIGHEST ELEVATIONS. IN THE
LOWER ELEVATIONS, SOME OF THE MORE INTENSE SHOWERS AND
THUNDERSTORMS COULD CONTAIN PERIODS OF HEAVIER RAINFALL. WHILE THE
OVERALL THREAT REMAINS LOW, LOCALIZED FLASH FLOODING STILL CAN'T
BE RULED OUT ACROSS PARTS OF THE GREAT BASIN, SIERRAS, NORTHERN
ROCKIES, AND THE OLYMPIC PENINSULA. THE INCREASED PRESENCE OF
CLOUDS AND PRECIPITATION ASSOCIATED WITH THE PASSING DISTURBANCES
AND PERSISTENT UPPER-LEVEL TROUGHING WILL RESULT IN HIGH
TEMPERATURES ROUGHLY 5 TO 15 DEGREES BELOW NORMAL ACROSS MUCH OF
THE WESTERN U.S. THROUGH FRIDAY AND LEADING INTO THE WEEKEND.
A LARGE AND STRENGTHENING UPPER-LEVEL RIDGE OVER THE CENTRAL U.S.
WILL CONTINUE TO PRODUCE AN EXTENDED PERIOD OF UNSEASONABLY HOT
WEATHER ACROSS THE PLAINS AND MIDWEST THROUGH THE END OF THE WEEK.
THE HOTTEST WEATHER RELATIVE TO CLIMATOLOGY WILL BE CONFINED TO
THE NORTHERN PLAINS AND UPPER MIDWEST, WHERE HIGH TEMPERATURES
WILL SOAR TO BETWEEN 10 AND 20 DEGREES ABOVE NORMAL TODAY AND
THURSDAY, TO BETWEEN 20 AND 30 DEGREES ABOVE NORMAL ON FRIDAY. IN
FACT, SEVERAL PLACES HAVE THE POTENTIAL TO TIE OR BREAK HIGH
TEMPERATURE RECORDS ON FRIDAY. ONE SUCH LOCATION IS MINNEAPOLIS,
MN WITH A FORECAST HIGH OF 90 DEGREES SET TO TIE THE DAILY RECORD
OF 90F SET BACK IN 1997. SAFE TO SAY, IT WILL BE FEELING MUCH MORE
SUMMER-LIKE THAN FALL-LIKE AS WE ROLL THE CALENDAR INTO OCTOBER.
