...FIRST WINTER STORM OF THE SEASON FOR INLAND NEW ENGLAND AND THE
MID-ATLANTIC CONTINUES TODAY WITH HEAVY SNOW AND IMPACTFUL ICING...
...SNOW SHOWERS FORECAST ACROSS THE NORTHERN PLAINS/GREAT LAKES
AND GREAT BASIN/ROCKIES OVER THE NEXT COUPLE OF DAYS IN AN ACTIVE
WINTER-LIKE PATTERN...
...CHILLY TEMPERATURES CONTINUE ACROSS MUCH OF THE EASTERN AND
CENTRAL U.S....
AN ACTIVE WINTER-LIKE PATTERN CONTINUES OVER THE CONUS, WITH A
WINTER-STORM RAMPING UP AS IT MOVES INTO NEW ENGLAND AND THE
MID-ATLANTIC TODAY. AN UPPER-WAVE WITH MOIST GULF FLOW OVERRUNNING
A FRONTAL BOUNDARY ALONG THE SOUTHEAST ATLANTIC AND GULF COASTS
HAS LED TO WIDESPREAD PRECIPITATION ACROSS THE MIDWEST/SOUTHEAST
OVERNIGHT. SHOWERS AND THUNDERSTORMS HAVE FOCUSED IN VICINITY OF
THE BOUNDARY ALONG THE COAST WITH SOME ADDITIONAL RAIN SHOWERS
FURTHER INLAND OVER THE SOUTHEAST, WHICH WILL PUSH EASTWARD AND
CLEAR THE COAST THROUGH THE DAY. FURTHER NORTH, A MESSY WINTRY MIX
IS MOVING EASTWARD FROM THE OHIO VALLEY INTO THE CENTRAL/SOUTHERN
APPALACHIANS AND PORTIONS OF THE MID-ATLANTIC THIS MORNING, WITH
ONGOING SNOW SHOWERS FROM THE UPPER OHIO VALLEY NORTH TO THE LOWER
GREAT LAKES SHIFTING EASTWARD INTO INTERIOR NEW ENGLAND AND THE
MID-ATLANTIC. MEANWHILE, A COASTAL LOW IS DEEPENING ALONG THE
MID-ATLANTIC, HELPING TO INCREASE MOIST FLOW OVER THE COLDER AIR
INLAND AND SIGNIFICANTLY ENHANCE THE WINTRY PRECIPITATION ACROSS
THE REGION. THIS WINTER STORM WILL BRING IMPACTFUL SNOW FOR
INTERIOR NEW ENGLAND AND THE NORTHERN MID-ATLANTIC TODAY, WITH
PERIODIC SNOWFALL RATES OF 1+"/HR LEADING TO TOTALS OF 5-10", WITH
LOCALLY HIGHER AMOUNTS OVER A FOOT POSSIBLE. IN ADDITION, FREEZING
RAIN THIS MORNING ALONG THE CENTRAL/SOUTHERN APPALACHIANS MAY
RESULT IN LIGHT ACCRETIONS OF 0.1-0.2 INCHES, CREATING SLIPPERY
AND DANGEROUS CONDITIONS ON ROADWAYS. PRECIPITATION ALONG THE
COAST INLAND TO THE I-95 CORRIDOR WILL LIKELY REMAIN MOSTLY RAIN.
THE WINTRY PRECIPITATION SHOULD TAPER OFF FROM SOUTH TO NORTH
THROUGHOUT THE DAY AS THE LOW BEGINS TO PULL AWAY FROM THE COAST,
WITH SNOWFALL LINGERING LONGEST INTO EARLY WEDNESDAY FOR NEW
ENGLAND.
TO THE WEST, ANOTHER COUPLE SYSTEMS ARE BRINGING WINTRY WEATHER TO
PORTIONS OF THE CENTRAL AND WESTERN U.S. FIRST, AN UPPER-WAVE
DROPPING SOUTHWARD THROUGH THE GREAT BASIN/ROCKIES WILL BRING
MODERATE TO LOCALLY HEAVY MOUNTAIN SNOW OVER THE NEXT COUPLE OF
DAYS. LOWER ELEVATIONS WILL ALSO SEE SOME SNOW SHOWERS, THOUGH
ACCUMULATIONS WILL GENERALLY REMAIN LIMITED. HOWEVER, ONE
EXCEPTION WILL BE ALONG THE COLORADO FRONT RANGE WHERE AREAS OF
THE HIGH PLAINS ALONG AND EAST OF THE FOOTHILLS ARE FORECAST TO
SEE SOME MODERATE ACCUMULATIONS. TO THE NORTH, A CLIPPER-LIKE
SYSTEM WILL BRING LIGHT SNOW SHOWERS TO THE NORTHERN PLAINS
TUESDAY. AS THE SYSTEM REACHES THE GREAT LAKES WEDNESDAY,
LAKE-ENHANCED SNOW SHOWERS WILL BRING MORE MODERATE ACCUMULATIONS
TO FAVORABLE DOWNWIND LOCATIONS. ELSEWHERE, SHOWER AND
THUNDERSTORM CHANCES WILL INCREASE ALONG PORTIONS OF THE
CENTRAL/WESTERN GULF COAST LATE WEDNESDAY AND INTO EARLY TUESDAY
AS A FRONTAL BOUNDARY LINGERING IN THE GULF BEGINS TO LIFT BACK
NORTHWARD. SOME MODERATE TO LOCALLY HEAVY RAINFALL WILL BE
POSSIBLE, THOUGH THIS WILL BE MORE LIKELY INTO THE DAY THURSDAY.
MUCH OF THE EASTERN AND CENTRAL U.S. WILL CONTINUE TO SEE WELL
BELOW AVERAGE, VERY CHILLY TEMPERATURES IN THIS WINTER-LIKE
PATTERN WITH BROAD, STAGNANT UPPER-TOUGHING IN PLACE AND REPEATED
COLD FRONT PASSAGES. FORECAST HIGHS GENERALLY RANGE FROM THE 20S
AND 30S FOR THE MIDWEST AND NEW ENGLAND, THE 30S AND 40S FOR THE
MID-ATLANTIC, AND THE 40S AND 50S FOR THE SOUTHEAST. AREAS ALONG
THE SOUTHEAST ATLANTIC COAST TUESDAY AND THE CENTRAL/WESTERN GULF
COAST WEDNESDAY WILL SEE MUCH WARMER HIGHS INTO THE 60S AS THE
POSITION OF THE LINGERING FRONTAL BOUNDARY FLUCTUATES. THE HIGH
PLAINS WILL ALSO SEE A WARM UP TODAY AS HIGHS RISE INTO THE
30S/40S NORTH AND 50S/60S SOUTH WITH DOWNSLOPING WINDS IN PLACE.
ANOTHER COLD FRONT WILL BRING A RETURN OF FRIGID TEMPERATURES
WEDNESDAY AS HIGHS PLUMMET INTO THE SINGLE DIGITS AND TEENS IN THE
NORTHERN PLAINS AND 20S AND 30S INTO THE CENTRAL HIGH PLAINS. THIS
COLD FRONT WILL ALSO BRING THE POTENTIAL FOR WIDESPREAD NEAR
RECORD-TYING/BREAKING LOWS THURSDAY MORNING ACROSS PORTIONS OF THE
MIDWEST, WITH TEMPERATURES AS LOW AS THE NEGATIVE TEENS. THE WEST
WILL GENERALLY REMAIN AT OR ABOVE AVERAGE, WITH HIGHS IN THE 40S
FOR THE INTERIOR, 50S AND 60S ALONG THE WEST COAST, AND 60S AND
70S IN THE DESERT SOUTHWEST. A COLD FRONT WILL BRING SOME COOLER
TEMPERATURES IN THE 30S TO PORTIONS OF THE INTERIOR ON WEDNESDAY.
