...A MAJOR STORM WILL PRODUCE WIDESPREAD, SIGNIFICANT IMPACTS OVER
MUCH OF THE U.S. THIS WEEK...
...A MAJOR WINTER STORM WILL BRING SEVERAL FEET OF SNOW TO THE
WASHINGTON AND OREGON CASCADES THROUGH TUESDAY...
A DEEP AND DYNAMIC MID-LATITUDE CYCLONE WILL ORGANIZE OVER THE
CENTRAL/SOUTHERN PLAINS THIS MORNING. SNOW WILL DEVELOP IN THE
PLAINS TODAY AND ADVANCE INTO THE MIDWEST TONIGHT AND TUESDAY.
BURSTS OF HEAVY SNOW MAY ACCUMULATE UP TO TWO INCHES IN AN HOUR,
AND RESULT IN HAZARDOUS TRAVEL. A HEAVY, WET SNOW WILL ALSO
DEVELOP IN THE INTERIOR NORTHEAST TUESDAY AFTERNOON AND NIGHT. A
BLIZZARD IS EXPECTED IN THE PLAINS OF NORTHEAST NEW MEXICO,
EASTERN COLORADO, THE OKLAHOMA AND TEXAS PANHANDLES, WESTERN
KANSAS AND SOUTHWEST NEBRASKA. WIND GUSTS AS HIGH AS 60-70 MPH
WILL CREATE FEROCIOUS BLIZZARD CONDITIONS WITH WHITEOUTS. TRAVEL
WILL BECOME EXTREMELY DANGEROUS TO IMPOSSIBLE. IF YOU MUST TRAVEL,
PACK A WINTER SURVIVAL KIT AS WIND CHILLS WILL PLUMMET BELOW ZERO.
THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS THE
CENTRAL GULF COAST TONIGHT INTO EARLY TUESDAY MORNING. SEVERE
THUNDERSTORMS CAPABLE OF PRODUCING STRONG WIND GUSTS AND TORNADOES
ARE EXPECTED FROM SOUTHEAST TEXAS ACROSS THE CENTRAL GULF COAST
THIS AFTERNOON INTO EARLY TUESDAY MORNING. THIS ENHANCED RISK OF
SEVERE THUNDERSTORMS SHIFTS INTO PARTS OF SOUTHEASTERN ALABAMA,
NORTHERN FLORIDA AND PARTS OF THE CAROLINA PIEDMONT/COASTAL PLAIN
ON TUESDAY. VERY STRONG AND DAMAGING WINDS AS WELL AS A FEW
TORNADOES WILL BE THE MAIN THREATS.
WIDESPREAD AND POTENTIALLY SIGNIFICANT RIVER AND FLASH FLOODING
ARE LIKELY FOR THE CENTRAL GULF COAST AND EASTERN U.S. THROUGH
EARLY WEDNESDAY. POWERFUL ONSHORE WINDS WILL LEAD TO WIDESPREAD
COASTAL FLOODING ALONG THE EASTERN GULF COAST AND MUCH OF THE EAST
COAST. SIGNIFICANT COASTAL FLOODING IS LIKELY, ESPECIALLY ON THE
MID-ATLANTIC COASTLINE, INCLUDING TIDAL RIVERS AND BAYS. THERE'S A
MODERATE RISK OF EXCESSIVE RAINFALL LEADING TO FLASH FLOODING OVER
PARTS OF SOUTHEAST LOUISIANA, SOUTHERN MISSISSIPPI AND
SOUTHWESTERN ALABAMA TODAY WHERE SEVERAL INCHES OF RAINFALL MAY
ACCUMULATE. THE MODERATE RISK OF EXCESSIVE RAINFALL SHIFTS INTO
THE MID-ATLANTIC ON TUESDAY BETWEEN NORTHERN VIRGINIA, UP THE I-95
CORRIDOR AND INTO WESTERN MASSACHUSETTS, WHERE EXISTING SNOWPACK
FROM THE RECENT SNOWSTORM MAY CAUSE ADDITIONAL RUNOFF CONCERNS.
WIDESPREAD WIND GUSTS IN EXCESS OF 50 MPH ARE LIKELY IN THE
EASTERN GULF COAST, CENTRAL APPALACHIANS, MUCH OF THE EAST COAST
AND NEW ENGLAND. PREPARE FOR POWER OUTAGES.
ELSEWHERE, YET ANOTHER PAIR OF POWERFUL WINTER STORM SYSTEMS WILL
CROSS THE PACIFIC NORTHWEST TONIGHT AND TUESDAY NIGHT WITH SEVERAL
FEET OF HEAVY SNOW AND STRONG WINDS EXPECTED ACROSS THE CASCADES.
BLIZZARD CONDITIONS ARE LIKELY. SNOW LEVELS RISE TO AROUND 5000'
TONIGHT WITH AN ATMOSPHERIC RIVER, BUT WILL QUICKLY FALL TO
BETWEEN 1500 AND 2500 FEET BEHIND A COLD FRONT ON TUESDAY, LEADING
TO CONSIDERABLE IMPACTS FOR MANY MOUNTAIN PASSES WITH THE SECOND
STORM TUESDAY NIGHT. OVER A FOOT OF SNOW IS LIKELY (70-90%) IN THE
HIGHER ELEVATIONS OF THE NORTHERN ROCKIES ON TUESDAY AND WEDNESDAY.
