EASTERN U.S. SUNDAY; AREAS OF MODERATE LAKE-EFFECT SNOW POSSIBLE

A WINTER STORM ASSOCIATED WITH AN UPPER-LEVEL TROUGH/SURFACE
FRONTAL SYSTEM MOVING THROUGH THE CENTRAL/SOUTHERN ROCKIES WILL
CONTINUE TODAY, WITH SNOW TAPERING OFF FOR THE CENTRAL/SOUTHERN
ROCKIES AND ADJACENT PORTIONS OF THE HIGH PLAINS WHILE SHIFTING
DEEPER INTO THE CENTRAL PLAINS. AN AXIS OF MODERATE TO HEAVY
SNOWFALL IS FORECAST FROM SOUTHWESTERN TO NORTHEASTERN KANSAS WITH
TOTALS OF 4-8 INCHES POSSIBLE. GUSTY WINDS AS WELL AS HEAVY SNOW
BANDS WITH RATES OF 1"/HR AT TIMES WILL CONTRIBUTE TO HAZARDOUS
TRAVEL CONDITIONS. A WINTRY MIX WITH ADDITIONAL LIGHTER
ACCUMULATIONS OF SNOW IS EXPECTED FROM THE TEXAS/OKLAHOMA
PANHANDLES THROUGH SOUTHEASTERN KANSAS INTO NORTHERN MISSOURI.
CONDITIONS SHOULD CLEAR OUT BY SUNDAY MORNING.
SOME LOCALLY HEAVY RAINFALL WILL BE POSSIBLE WITH THUNDERSTORMS IN
SOUTH FLORIDA SATURDAY, WITH A CHANCE OF AN ISOLATED INSTANCES OR
TWO OF FLASH FLOODING. THEN, AS THE UPPER-LEVEL TROUGH AND A PAIR
OF SURFACE FRONTAL SYSTEMS BEGIN TO SHIFT RAPIDLY EASTWARD, AN
AREA OF EXPANDING SHOWERS AND SOME THUNDERSTORMS IS EXPECTED
ACROSS THE EASTERN U.S., STARTING LATE SATURDAY/EARLY SUNDAY FOR
PORTIONS OF TEXAS TO THE LOWER MISSISSIPPI VALLEY, EVENTUALLY
PUSHING THROUGH THE OHIO VALLEY AND SOUTHEAST TOWARDS THE EAST
COAST BY LATER SUNDAY AFTERNOON. MORE MODERATE TO HEAVIER AMOUNTS
ARE MOST LIKELY ALONG THE GULF COAST AND ALSO ACROSS PORTIONS OF
NEW ENGLAND AS A COASTAL LOW ORGANIZES TO THE SOUTHEAST. A WINTRY
MIX WILL BE POSSIBLE FURTHER NORTH AND WEST FROM THE MIDWEST INTO
THE APPALACHIANS AND THE INTERIOR NORTHEAST, THOUGH ANY
ACCUMULATIONS SHOULD REMAIN LIMITED. HOWEVER, NORTHWESTERLY FLOW
OVER THE GREAT LAKES WILL LEAD TO SOME LOCALLY ENHANCED AREAS OF
MODERATE LAKE EFFECT SNOWFALL, PARTICULARLY FOR FAVORABLE AREAS OF
THE UPPER AND LOWER PENINSULAS OF MICHIGAN WHERE TOTALS SUNDAY
COULD EXCEED 4".
TEMPERATURES WILL GENERALLY BE BELOW AVERAGE FOR MUCH OF THE
COUNTRY THIS WEEKEND, WITH THE GREATEST ANOMALIES IN PORTIONS OF
THE CENTRAL AND SOUTHERN PLAINS. HIGHS ON SATURDAY WILL BE IN THE
20S AND 30S FOR THE CENTRAL PLAINS AND 40S INTO NORTHERN PORTIONS
OF THE SOUTHERN PLAINS, WITH MORNING LOWS SUNDAY DIPPING INTO THE
TEENS AND 20S, LEADING TO WIND CHILLS IN THE SINGLE DIGITS AND
POTENTIALLY EVEN BELOW 0 FOR SOME LOCATION. HIGHS IN THE 30S AND
40S WILL BE COMMON IN THE SOUTHWEST WITH 50S AND 60S IN THE SOUTH.
TEMPERATURES WILL BE WELL BELOW AVERAGE AS WELL SATURDAY IN NEW
ENGLAND, WITH 20S AND 30S FORECAST, AS WELL AS IN THE
MID-ATLANTIC, WHERE 40S ARE EXPECTED. CONDITIONS SHOULD MODERATE A
BIT SUNDAY. THE WEST WILL ALSO SEE MANY AREAS BELOW AVERAGE, WITH
30S AND 40S FOR MUCH OF THE INTERIOR AND 60S TO LOW 70S FOR THE
DESERT SOUTHWEST. THE WEST COAST WILL BE CLOSER TO AVERAGE, WITH
50S AND 60S, AND 70S FOR SOUTHERN CALIFORNIA. HOWEVER, THE CENTRAL
CALIFORNIA VALLEYS AS WELL AS NORTHERN PORTIONS OF THE MOJAVE
DESERT WILL SEE LOWS NEAR THE FREEZING MARK, WITH FREEZE-RELATED
ADVISORIES IN PLACE.
