AND NORTHEAST WITH A COMBINATION OF SNOW, SLEET AND FREEZING RAIN
TODAY...
...NEXT ROUND OF UNSETTLED WEATHER TO ENTER THE WEST TODAY WITH
THE THREAT OF HEAVY RAINFALL/SNOWS FOR CALIFORNIA BEFORE SNOWFALL
CHANCES SPREAD ACROSS THE NORTHERN ROCKIES AND NORTHERN PLAINS
INTO SATURDAY...
...RECORD HIGH TEMPERATURES ARE EXPECTED ACROSS MUCH OF THE
SOUTHERN U.S. OVER THE NEXT FEW DAYS...
A WINTER STORM CURRENTLY IMPACTING MUCH OF THE GREAT LAKES, UPPER
OHIO VALLEY AND NORTHERN MID-ATLANTIC WITH LIGHT SNOW AND A WINTRY
MIX IS FORECAST TO CONTINUE TODAY WHILE QUICKLY PUSHING INTO THE
NORTHEAST. THE PRIMARY WINTER WEATHER HAZARDS ARE EXPECTED TO BE
ASSOCIATED WITH FREEZING RAIN AS WARM AIR ALOFT COMBINED WITH
STUBBORN COLD AT THE SURFACE LEADS TO AN ICY MORNING FOR MANY.
PRECIPITATION IS LIKELY TO BE COMING TO AN END ACROSS THE OHIO
VALLEY BY SUNRISE, WITH FREEZING RAIN LINGERING ACROSS THE
MID-ATLANTIC AND CENTRAL APPALACHIANS THIS MORNING. MEANWHILE,
SNOW IS EXPECTED TO CONTINUE ACROSS THE GREAT LAKES AND SHIFT INTO
MUCH OF THE NORTHEAST EARLY TODAY. TOTAL ICE ACCRETION OF UP TO A
HALF INCH IS POSSIBLE ACROSS PARTS OF EASTERN WV, WESTERN MD, FAR
NORTHERN VA, AND INTO PARTS OF SOUTH-CENTRAL PA. THIS MAY LEAD TO
SCATTERED POWER OUTAGES AND TREE DAMAGE. ELSEWHERE, UP TO A
QUARTER INCH OF ICE IS POSSIBLE JUST NORTHWEST OF THE I-95
CORRIDOR FROM WASHINGTON D.C. TO PHILADELPHIA, AS WELL AS MUCH OF
PA, NORTHERN OH, NORTHERN IN, AND SOUTHERN MI. THIS AMOUNT OF ICE
IS CAPABLE OF MAKING UNTREATED ROADWAYS TREACHEROUS. THE SNOWFALL
ASPECT OF THIS STORM WILL FEATURE LIGHT AMOUNTS (GENERALLY UNDER A
COUPLE INCHES) ACROSS THE GREAT LAKES OUTSIDE OF LAKE-EFFECT SNOW
IN THE EASTERN U.P. OF MICHIGAN, WITH 2 TO 5 INCHES EXPECTED
THROUGHOUT MUCH OF NEW ENGLAND. MUCH OF THE WINTER WEATHER IS
ANTICIPATED TO QUICKLY END BY THIS EVENING AND BE FOLLOWED BY
BREEZY WESTERLY WINDS AS A DEEPENING LOW PRESSURE SYSTEM SWINGS
ACROSS SOUTHEAST CANADA. IN FACT, STRONG WINDS HAVE PROMPTED
BLIZZARD WARNINGS TODAY ACROSS THE KEWEENAW PENINSULA OF MI AND
NEIGHBORING COUNTIES.
THE NEXT STORM SYSTEM TO ENTER THE WEST COAST AND EVENTUALLY
SPREAD WINTRY WEATHER ELSEWHERE THROUGHOUT THE LOWER 48 IS
FORECAST TO MOVE ONSHORE LATER TODAY. INITIALLY, HEAVY
COASTAL/LOWER ELEVATION RAIN IS EXPECTED ACROSS CA WITH HEAVY SNOW
LIKELY INTO THE SIERRA NEVADA, NORTHERN CA RANGES AND SOUTHERN OR.
BY FRIDAY, THE MODERATE TO HEAVY SNOWFALL LOCATED JUST NORTH OF AN
ASSOCIATED AREA OF LOW PRESSURE SHIFTS INTO THE NORTHERN GREAT
BASIN AND NORTHERN ROCKIES. TOTAL SNOWFALL AMOUNTS OVER A FOOT ARE
EXPECTED ACROSS THE HIGHER TERRAIN, WITH MULTIPLE FEET OF HEAVY
SNOW POSSIBLE IN THE SIERRA NEVADA. BY EARLY THIS WEEKEND THE
SNOWFALL POTENTIAL ENTERS THE NORTHERN PLAINS, WHERE HIGH
PROBABILITIES (70-90%) FOR AT LEAST 4 INCHES OF SNOW STRETCHES
EAST-WEST FROM NORTHERN ND ACROSS CENTRAL MN, AND INTO CENTRAL WI.
AS THE SYSTEM CONTINUES TO SLIDE EASTWARD ON SATURDAY NIGHT,
WINTRY WEATHER WILL QUICKLY BEGIN TO IMPACT MUCH OF THE GREAT
LAKES, UPPER OHIO VALLEY, MID-ATLANTIC, AND NORTHEAST. FREEZING
RAIN IS POSSIBLE FOR SOUTHERN AREAS SIMILAR TO WHERE THE ONGOING
ICE THREAT EXISTS TODAY, WITH HEAVY SNOW (OVER 4 INCHES) MOST
LIKELY IN THE NORTHEAST. BE SURE TO CHECK LOCAL FORECASTS FOR THE
LATEST UPDATED INFORMATION.
WHILE WINTER STORM SYSTEMS CROSS THE MIDDLE AND NORTHERN U.S.,
MUCH OF THE SOUTH IS FORECAST TO REMAIN QUITE WARM. IN FACT, SOME
AREAS COULD SEE RECORD BREAKING WARMTH CONTINUE THROUGH THIS
WEEKEND AS HIGHS INTO THE 70S AND 80S STRETCH FROM THE SOUTHWEST
TO THE SOUTHERN PLAINS AND MUCH OF THE SOUTHEAST. DOZENS OF
STATIONS ACROSS 13 STATES BETWEEN ARIZONA AND NORTH CAROLINA ARE
CURRENTLY FORECAST TO BREAK OR TIE DAILY HIGH TEMPERATURE RECORDS.
MEANWHILE, THE COLDEST AIR OVER THE NEXT FEW DAYS WILL BE CONFINED
TO THE NORTHERN HIGH PLAINS AS HIGHS REMAIN IN THE SINGLE DIGITS
AND LOWS DIP WELL BELOW ZERO.
