NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
258 AM EST FRI JAN 05 2024
VALID 12Z FRI JAN 05 2024 - 12Z SUN JAN 07 2024
...LIGHT TO MODERATE SNOW EXPECTED FOR PORTIONS OF THE SOUTHERN
AND CENTRAL GREAT PLAINS ALONG WITH LOCALIZED FLASH FLOODING FOR
THE GULF COAST TODAY...
...SIGNIFICANT ICING POSSIBLE FOR PORTIONS OF THE SOUTHERN AND
CENTRAL APPALACHIANS TONIGHT INTO SATURDAY...
...SNOW FROM DEVELOPING EAST COAST WINTER STORM TO BEGIN AFFECTING
INTERIOR PORTIONS OF THE MID-ATLANTIC AND NORTHEAST ON SATURDAY...
...PACIFIC STORM SYSTEM TO BRING RENEWED ROUND OF HEAVY MOUNTAIN
SNOW AND COASTAL RAIN TO THE NORTHWEST COAST TONIGHT INTO
SATURDAY...
AN UPPER TROUGH MOVING THROUGH THE PLAINS AND MISSISSIPPI VALLEY
WILL SUPPORT THE DEVELOPMENT OF A DYNAMIC STORM SYSTEM IMPACTING
AN THE GREAT PLAINS TO THE EAST COAST THIS WEEKEND. TODAY, THIS
UPPER DISTURBANCE WILL GENERATE LIGHT TO MODERATE SNOW ACROSS
PORTIONS OF KANSAS, OKLAHOMA AND MISSOURI, WHILE PRODUCING SHOWERS
AND THUNDERSTORMS OVER MUCH OF THE WESTERN/CENTRAL GULF COAST.
NORTHERN STREAM ENERGY PIVOTING OVER CENTRAL CANADA WILL SUPPORT
ADDITIONAL SNOW SHOWERS ACROSS PORTIONS OF THE NORTHERN PLAINS AND
UPPER MIDWEST BEGINNING THIS AFTERNOON AND CONTINUING INTO THE
GREAT LAKES THROUGH SATURDAY BEFORE PHASING WITH THE NOR'EASTER.
FOR THE INTERIOR MID-ATLANTIC AND NEW ENGLAND, THERE IS INCREASING
CONFIDENCE IN HEAVY SNOW FROM SATURDAY AFTERNOON INTO SUNDAY. THE
GREATEST UNCERTAINTY IN THE RAIN-SNOW TRANSITION IS FROM SOUTHEAST
PENNSYLVANIA AND NORTHERN NEW JERSEY INTO SOUTHERN NEW ENGLAND.
PEOPLE IN THOSE AREAS SHOULD STILL BE PREPARED FOR THE POSSIBILITY
OF SNOW, AND CHANGES TO THE FORECAST. NORTH OF THOSE AREAS,
CONFIDENCE IN HEAVY SNOW IS HIGHER. THE COMBINATION OF HEAVY, WET
SNOW AND GUSTY WINDS IN CONNECTICUT, RHODE ISLAND AND
MASSACHUSETTS MAY LEAD TO SOME POWER OUTAGES AND TREE DAMAGE.
GUSTY ONSHORE WINDS MAY LEAD TO MINOR FLOODING ALONG THE
MID-ATLANTIC AND SOUTHERN NEW ENGLAND COASTS, PARTICULARLY FOR THE
SUNDAY MORNING HIGH TIDE CYCLE. IN THE APPALACHIAN REGION OF
WESTERN NORTH CAROLINA, WESTERN VIRGINIA AND EASTERN WEST
VIRGINIA, ACCUMULATIONS OF ICE IN EXCESS OF 0.1 INCHES, DUE TO
FREEZING RAIN, ARE LIKELY WITH LOCALLY HIGHER ACCUMULATIONS
POSSIBLE. THIS ICING, ALONG WITH SOME AREAS OF SLEET, MAY PRODUCE
HAZARDOUS TRAVEL CONDITIONS TONIGHT AND SATURDAY.
MEANWHILE, ANOTHER EAST PACIFIC SYSTEM WILL ENTER THE WEST
TONIGHT, BRINGING HEAVY MOUNTAIN SNOW TO THE WESTERN MOUNTAINS AND
COASTAL RAIN TO THE NORTHWEST COAST THROUGH SUNDAY. AROUND A FOOT
OF SNOW IS EXPECTED FOR THE CASCADES AND SIERRA WHILE SLIGHTLY
LESSER TOTALS ARE POSSIBLE FOR THE HIGHEST PEAKS OF THE
INTERMOUNTAIN WEST. THIS SYSTEM WILL GO ON TO INTENSIFY INTO A
DYNAMIC STORM OVER THE GREAT PLAINS AND CAUSE WIDESPREAD IMPACTS
FROM THERE TO THE EAST COAST EARLY TO MID WEEK.
