...WINTER STORM WITH AREAS OF HEAVY SNOW AND GUSTY WINDS CONTINUES
FURTHER INTO THE CENTRAL PLAINS SATURDAY...
...BROAD AREA OF SHOWERS AND THUNDERSTORMS EXPECTED ACROSS THE
EASTERN U.S. SUNDAY; AREAS OF LAKE-EFFECT SNOW POSSIBLE FOR THE

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 INSTANCE OR
TWO OF FLASH FLOODING. THEN, AS THE UPPER-LEVEL TROUGH AND A PAIR
OF SURFACE FRONTAL SYSTEMS BEGIN TO SHIFT 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. SOME MODERATE TO HEAVIER RAINFALL IS 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 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 LOCATIONS. 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. HIGHS IN THE
30S AND 40S WILL BE COMMON IN THE MIDWEST WITH 50S AND 60S IN THE
SOUTH. THE WEST WILL ALSO SEE MANY AREAS BELOW AVERAGE, WITH 30S
AND 40S FOR MUCH OF THE INTERIOR MOUNTAIN WEST AND 60S TO LOW 70S
FOR THE DESERT SOUTHWEST. THE WEST COAST WILL BE CLOSER TO AVERAGE
WITH 50S AND 60S EXPECTED, AND 70S FOR SOUTHERN CALIFORNIA.
HOWEVER, THE CENTRAL CALIFORNIA VALLEYS AS WELL AS NORTHERN
PORTIONS OF THE MOJAVE DESERT WILL SEE LOWS NEAR OR BELOW
FREEZING, WITH FREEZE-RELATED ADVISORIES IN PLACE.
