BRING HEAVY SNOW FROM THE CENTRAL U.S. ACROSS THE MIDWEST, OHIO
VALLEY, AND THROUGH THE NORTHEASTERN U.S. FOR THE REMAINDER OF THE
WEEKEND INTO MONDAY...
...THE SAME STORM SYSTEM WILL ALSO BRING WIDESPREAD HEAVY ICE
ACCUMULATION FROM THE SOUTHERN PLAINS TO THE
MID-ATLANTIC/SOUTHEAST WHERE CRIPPLING TO LOCALLY CATASTROPHIC
IMPACTS CAN BE EXPECTED...
...THE SAME STORM SYSTEM COULD ALSO BRING SEVERE THUNDERSTORMS
ACROSS THE CENTRAL TO EASTERN GULF STATES ON SUNDAY...
...RECORD COLD TEMPERATURES AND DANGEROUSLY COLD WIND CHILLS
DESCENDING FURTHER INTO THE GREAT PLAINS, ESPECIALLY THE SOUTHERN
PLAINS BY MONDAY...
AN OUTBREAK OF ARCTIC AIR FROM CANADA INTERACTING WITH WIDESPREAD
MOISTURE WELL AHEAD OF AN UPPER-LEVEL LOW MOVING ONSHORE INTO
NORTHWESTERN MEXICO IS CURRENTLY PRODUCING AN UNUSUALLY EXPANSIVE
WINTER STORM ACROSS THE CENTRAL TO SOUTHERN U.S. AND INTO THE OHIO
VALLEY. THE ASCENDING DYNAMICS ON THE SOUTHWESTERN FLANK OF A
STRONG JET STREAM ACROSS THE NORTHEASTERN U.S. WILL TRIGGER THE
FORMATION OF A LOW PRESSURE SYSTEM ACROSS THE DEEP SOUTH ON
SUNDAY. BY SUNDAY MORNING, THIS WEATHER PATTERN WILL CREATE AN
UNUSUALLY EXPANSIVE SWATH OF MODERATE TO HEAVY SNOW THAT WILL
STRETCH FROM THE SOUTH-CENTRAL PLAINS THROUGH THE MIDWEST AND OHIO
VALLEY, CROSSING THE CENTRAL APPALACHIANS, AND THROUGH THE
NORTHERN MID-ATLANTIC STATES. SOUTH OF THIS LONG SWATH OF
IMPACTFUL SNOW, AN UNUSUALLY EXPANSIVE STRETCH OF HEAVY SLEET AND
FREEZING RAIN IS FORECAST TO IMPACT THE INTERIOR SECTION OF THE
SOUTHERN PLAINS ACROSS THE ARKLATEX AND THROUGH THE TENNESSEE
VALLEY THROUGH SUNDAY AFTERNOON. THE HEAVY SLEET AND FREEZING
RAIN WILL ALSO IMPACT MANY AREAS OF THE EAST COAST AS FAR SOUTH AS
ATLANTA, GEORGIA THROUGH INTERIOR MID-ATLANTIC, AS FAR NORTH AS
NEW JERSEY, NEW YORK CITY AND POSSIBLY THE SOUTHERN COAST OF NEW
ENGLAND. SLEET ACCUMULATIONS OF 1-3 INCHES COUPLED WITH NARROW
SWATHS OF POSSIBLY AN INCH OR MORE OF ICE ACCUMULATION WOULD
RESULT IN CRIPPLING TO LOCALLY CATASTROPHIC IMPACTS ACROSS
PORTIONS OF THE SOUTH, INTERIOR SOUTHEAST INTO THE MID-ATLANTIC
THROUGH SUNDAY. ACROSS THE LOWER GREAT LAKES THROUGH NEW ENGLAND,
MODERATE TO HEAVY SNOW IS FORECAST TO OVERSPREAD THE ENTIRE REGION
FROM WEST TO EAST LATER ON SUNDAY AND WILL LINGER ACROSS NEW
ENGLAND WITH ONLY A GRADUAL DECREASE IN SNOWFALL INTENSITY ON
MONDAY AS A NEW LOW PRESSURE CENTER DEVELOPS AND INTENSIFIES NEAR
THE SOUTHEAST NEW ENGLAND COAST.
AS THE AFOREMENTIONED LOW PRESSURE SYSTEM DEVELOPS AND MOVES
ACROSS THE TENNESSEE VALLEY ON SUNDAY, A STRONG COLD FRONT
TRAILING FROM THE LOW PRESSURE CENTER WILL LIFT AN INFLUX OF
MOISTURE FROM THE GULF AND TRIGGER STRONG TO SEVERE THUNDERSTORMS
ACROSS THE CENTRAL TO EASTERN GULF COAST STATES ON SUNDAY. ARCTIC
AIR WILL THEN POUR FURTHER DOWN THE GREAT PLAINS INTO THE GULF
COAST AND BEGIN TO RUSH INTO THE ENTIRE EAST COAST ON MONDAY
BEHIND THE LOW PRESSURE SYSTEM. BELOW FREEZING TEMPERATURES ARE
FORECAST TO REACH AS FAR SOUTH AS BROWNSVILLE, TEXAS WITH AS LOW
AS BELOW ZERO READINGS ACROSS THE TEXAS PANHANDLE AND INTO
OKLAHOMA MONDAY MORNING. THESE BITTERLY COLD TEMPERATURES WILL BE
AT RECORD-BREAKING LEVELS ACROSS THE ENTIRE SOUTHERN PLAINS
BEGINNING SUNDAY MORNING AND ESPECIALLY MONDAY MORNING. THESE
RECORD COLD TEMPERATURES WILL ALSO COMBINE WITH BRISK NORTHERLY
WINDS TO PRODUCE DANGEROUSLY COLD WIND CHILLS!
ACROSS THE NORTHERN HIGH PLAINS TO THE NORTHERN ROCKIES, A
REINFORCING ARCTIC FRONT WILL BRING A PERIOD OF SNOW THROUGH
TONIGHT, BEFORE SPREADING FARTHER SOUTH INTO THE COLORADO ROCKIES
AND THE CENTRAL HIGH PLAINS SUNDAY AND SUNDAY NIGHT. MEANWHILE,
THE ENTIRE WESTERN U.S. WILL BE QUIET WEATHERWISE WITH GENERALLY
MILDER THAN NORMAL TEMPERATURES IN CONTRAST TO THE COLD AND WINTRY
WEATHER ACROSS THE REMAINDER OF THE COUNTRY THOUGH THE WEEKEND AND
INTO EARLY NEXT WEEK. ACROSS THE GREAT LAKES, LAKE-EFFECT SNOWS
CAN BE EXPECTED TO LINGER THROUGH THE NEXT COUPLE OF DAYS IN
ADDITION TO THE SNOWFALL ASSOCIATED WITH THE WINTER STORM ACROSS
THE LOWER GREAT LAKES.
