...STRONG NOR'EASTER OFF THE MID-ATLANTIC AND NORTHEAST WILL BRING
COASTAL FLOODING, RIP CURRENTS, STRONG WIND GUSTS, AND HEAVY RAIN
TO THE REGION THIS WEEKEND...
...THERE IS A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL OVER
PARTS OF THE SOUTHERN HIGH PLAINS ON FRIDAY...
...THERE IS A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL OVER
PARTS OF THE SOUTHERN NEW ENGLAND ON SATURDAY AND SUNDAY...
AN UPPER-LEVEL TROUGH DIGGING INTO THE EASTERN U.S. WILL INTERACT
WITH A COOL AIR MASS SLIDING EAST INTO THE WESTERN ATLANTIC TO
STRENGTHEN A NOR'EASTER JUST OFF THE EAST COAST OVER THE NEXT FEW
DAYS. THE COOL AIR WILL BE MOISTENED AND LIFTED BY THE DIGGING
UPPER TROUGH AS A
LARGE HIGH PRESSURE SYSTEM FEEDS THAT COOL AIR ACROSS THE STILL
WARM WATERS OF THE WESTERN ATLANTIC. THE RESULT WILL BE A STRONG
NOR'EASTER THAT WILL BRING WIDESPREAD STRONG TO GALE-FORCE WINDS
TO MUCH OF THE EAST COAST OF THE U.S. THROUGH THE NEXT FEW DAYS.
THE CYCLONE CENTER WILL APPROACH AND THEN STALL JUST OFF SOUTHERN
NEW ENGLAND AND THE MID-ATLANTIC INTO THE WEEKEND. RAIN WILL
EXPAND ACROSS THE REGION LATER THIS AFTERNOON AND THROUGH
SATURDAY, WHICH MAY LEAD TO INLAND FLOODING. RAIN WILL CONTINUE TO
WRAP AROUND THE SYSTEM ON SUNDAY. ADDITIONALLY, WIND GUSTS IN
EXCESS OF 50 MPH ARE LIKELY, ESPECIALLY ALONG THE COAST, WHICH
COULD LEAD TO POWER OUTAGES. MODERATE TO MAJOR COASTAL FLOODING,
HIGH SURF, RIP CURRENTS, AND BEACH EROSION ARE ALSO POSSIBLE ALONG
THE COAST. PLEASE SEE THE LATEST WPC KEY
MESSAGES FOR THIS SYSTEM AT WPC.NCEP.NOAA.GOV.
UPPER-LEVEL ENERGY AND MOISTURE MOVING NORTHWESTWARD FROM THE GULF
WILL PRODUCE SHOWERS AND THUNDERSTORMS WITH HEAVY RAIN OVER PARTS
OF THE SOUTHERN HIGH PLAINS ON FRIDAY. THEREFORE, THE WPC HAS
ISSUED A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL WITH THESE
THUNDERSTORMS OVER PARTS OF THE SOUTHERN HIGH PLAINS. THE
ASSOCIATED HEAVY RAIN WILL CREATE MAINLY LOCALIZED AREAS OF FLASH
FLOODING, WITH URBAN AREAS, ROADS, SMALL STREAMS, NARROW
CANYONS/GULLIES, AND BURN SCARS THE MOST VULNERABLE. THE THREAT OF
HEAVY RAIN WILL END ON SATURDAY OVER THIS PORTION OF THE COUNTRY.
SHOWERS AND THUNDERSTORMS WILL CONTINUE OVER PARTS OF THE SOUTHERN
ROCKIES, SOUTHERN HIGH PLAINS, AND CENTRAL PLAINS THROUGH EARLY
SATURDAY MORNING. AS MOISTURE CONTINUES TO STREAM NORTHWARD OVER
THE PLAINS, SHOWERS AND THUNDERSTORMS WILL DEVELOP OVER PARTS OF
THE CENTRAL/SOUTHERN PLAINS AND THE UPPER/MIDDLE MISSISSIPPI
VALLEY ON SATURDAY INTO SUNDAY MORNING.
IN ADDITION, A FRONT MOVING OVER THE PACIFIC NORTHWEST WILL
PRODUCE RAIN WITH EMBEDDED THUNDERSTORMS OVER THE NORTHWEST INTO
THE NORTHERN INTERMOUNTAIN REGION WITH SNOW AT THE HIGHEST
ELEVATIONS ON FRIDAY.
