...HEAVY RAIN AND SOME SEVERE WEATHER EXPECTED TO MOVE ACROSS THE
SOUTHEAST TODAY FOLLOWED BY HEAVY RAIN AND STRONG WINDS ACROSS THE
MID-ATLANTIC AND SOUTHERN NEW ENGLAND TONIGHT INTO SUNDAY
MORNING...
...WET SNOW AND STRONG WINDS ACROSS NORTHERN NEW ENGLAND FROM
TONIGHT THROUGH MUCH OF SUNDAY FOLLOWED BY LAKE-EFFECT SNOWS
ACROSS THE LOWER GREAT LAKES INTO MONDAY MORNING...
...FREQUENT ROUNDS OF LOWER-ELEVATION RAIN AND MOUNTAIN SNOW
EXPECTED TO REACH THE PACIFIC NORTHWEST THROUGH THE NEXT COUPLE OF
DAYS...
A COMPLEX INTERACTION BETWEEN A COLD AIR MASS DIPPING INTO THE
MID-SECTION OF THE COUNTRY, AN AMPLIFYING UPPER-LEVEL TROUGH,
MOIST AIR FROM THE GULF OF MEXICO INGESTING INTO THE SOUTH, AND A
SUBTROPICAL JET STREAM WILL BRING WIDESPREAD INCREMENT WEATHER
THROUGH THE EASTERN U.S. INTO SUNDAY. THE HEAVIEST RAINFALL IS
EXPECTED TO BE FOUND ACROSS THE SOUTHEAST WHERE SOME OF THE
THUNDERSTORMS COULD BECOME SEVERE. THE WEATHER PREDICTION CENTER
HAS A SLIGHT RISK OF EXCESSIVE RAINFALL FORECAST FOR THE EASTERN
CAROLINAS FOR TODAY. THE LOW PRESSURE CENTER THAT FORMS AND
INTENSIFIES ALONG THE SOUTHERN FRONT IS FORECAST TO TRACK UP THE
EAST COAST AND REACH SOUTHERN NEW ENGLAND BY EARLY ON SUNDAY.
AREAS FROM CENTRAL APPALACHIANS INTO SOUTHERN NEW ENGLAND ARE
EXPECTED TO SEE A PERIOD OF MODERATE TO OCCASIONALLY HEAVY RAIN
LATER TODAY INTO EARLY SUNDAY AS THE LOW PRESSURE CENTER PASSES
JUST TO THE SOUTHEAST. FARTHER INLAND, COLDER AIR WRAPPING AROUND
THE INTENSIFYING STORM WILL SUPPORT WET SNOW ACROSS NORTHERN NEW
ENGLAND DURING THE SAME TIME PERIOD. THIS WILL BE FOLLOWED BY
LAKE-EFFECT SNOWS ACROSS THE LOWER GREAT LAKES INTO MONDAY MORNING
WHEN COLDER AIR POURS IN BEHIND THE BIG LOW. STRONG AND GUSTY
WINDS WILL EXPAND AND THEN ENGULF THE ENTIRE NORTHEASTERN U.S. AS
THE BIG LOW INTENSIFIES FURTHER AND BEGINS TO EXIT INTO THE
CANADIAN MARITIMES BY MONDAY MORNING.
IN THE WAKE OF THE STORMINESS IN THE EAST, HIGH PRESSURE WILL TAKE
OVER THE ENTIRE CENTRAL AND SOUTHERN U.S. WITH DRY CONDITIONS
PERSISTING INTO THE NEW WORK WEEK. THE DRY WEATHER WILL EXTEND
INTO MUCH OF THE WESTERN U.S. AS WELL. HOWEVER, MOISTURE
ASSOCIATED WITH THE NEXT PACIFIC SYSTEM IS FORECAST TO REACH THE
PACIFIC NORTHWEST IN A HURRY TODAY IN THE FORM OF LOWER-ELEVATION
RAIN AND MOUNTAIN SNOW FOR RATHER HIGH ELEVATIONS. MORE SYSTEMS
ARRIVING FROM THE PACIFIC WILL RESULT IN FREQUENT ROUNDS OF
PRECIPITATION PERSISTING ACROSS THE WESTERN PORTIONS OF
WASHINGTON, OREGON, AND DOWN INTO NORTHERN CALIFORNIA. THE
CASCADES AND HIGHER TERRAIN OF NORTHERN CALIFORNIA WILL LIKELY
RECEIVE A COUPLE MORE FEET OF NEW SNOW THROUGH MONDAY.
TEMPERATURES WILL GENERALLY BE COOLER THAN NORMAL ACROSS THE SOUTH
BUT ABOVE NORMAL ACROSS THE NORTH. THE EAST WILL BE MILDER THAN
NORMAL TODAY AHEAD OF THE INTENSIFYING LOW PRESSURE SYSTEM BEFORE
COLDER AIR SURGES INTO THE REGION ON SUNDAY. TEMPERATURES ACROSS
THE WEST WILL AVERAGE NEAR NORMAL.
