A BITTERLY COLD ARCTIC AIRMASS THAT HAS OVERSPREAD THE EASTERN
GREAT LAKES, OHIO VALLEY, MID-ATLANTIC, AND NORTHEAST FOLLOWING A
PAIR OF COLD FRONT PASSAGES IS EXPECTED TO PERSIST THROUGH
TONIGHT. LINGERING GUSTY WINDS WILL LEAD TO DANGEROUSLY COLD WIND
CHILLS AS LOW AS THE NEGATIVE 30S ACROSS THE INTERIOR
NORTHEAST/NEW ENGLAND AND THE SINGLE DIGITS AND TEENS ELSEWHERE,
PARTICULARLY THROUGH THE MORNING HOURS. CONDITIONS ARE EXPECTED TO
MODERATE THROUGH THE EARLY PART OF THE WEEK, WITH HIGHS MONDAY AND
TUESDAY INCREASING BY AROUND 10 DEGREES OR SO EACH DAY.
ONSHORE FLOW ACCOMPANYING A PACIFIC SYSTEM IS SPREADING
PRECIPITATION ACROSS THE PACIFIC NORTHWEST AND INTO THE ROCKIES
AND GREAT BASIN SUNDAY AFTERNOON. LIGHT TO MODERATE RAIN SHOWERS
SHOULD CONTINUE INITIALLY FOR LOWER ELEVATIONS/VALLEYS INLAND
THROUGH THE NORTHERN GREAT BASIN/ROCKIES. RAIN MAY TRANSITION TO
A WINTRY MIX FOR SOME LOWER ELEVATION LOCATIONS SUNDAY NIGHT INTO
EARLY MONDAY AS COOLER AIR FILTERS IN, THOUGH ACCUMULATIONS SHOULD
REMAIN LIMITED. SOME PRECIPITATION IS ALSO EXPECTED INTO ADJACENT
PORTIONS OF THE NORTHERN HIGH PLAINS. HIGHER ELEVATION MOUNTAIN
RANGES FROM THE SOUTHERN CASCADES TO THE NORTHERN ROCKIES WILL SEE
MODERATE TO LOCALLY HEAVY SNOWFALL. PRECIPITATION CHANCES WILL
QUICKLY DECREASE INTO THE DAY MONDAY AS THE INFLUX OF MOISTURE
ENDS, WITH THE SNOW LINGERING LONGEST FOR HIGHER ELEVATIONS OF THE
NORTHERN ROCKIES. ANOTHER SYSTEM LOOKS TO BRING SOME MODERATE
LOWER ELEVATION RAINFALL AND HEAVY HIGH ELEVATION SNOW FURTHER
SOUTH INTO CALIFORNIA AND THE SIERRAS TUESDAY.
THE NORTHERN TIER OF THE COUNTRY MAY SEE SOME LIGHT ICING AND SNOW
SHOWERS AS A CLIPPER-LIKE SYSTEM MOVING ALONG THE U.S./CANADIAN
BORDER. AS IT REACHES THE GREAT LAKES THE SYSTEM WILL INCREASE IN
INTENSITY YIELDING MODERATE SNOW FOR UPSTATE NEW YORK/NEW ENGLAND
TUESDAY. MOISTURE ADVECTING AHEAD OF A COLD FRONT IN THE
MISSISSIPPI VALLEY INTO THE SOUTHERN PLAINS WILL AID IN THE
DEVELOPMENT OF SHOWERS AND THUNDERSTORMS POSSIBLY AS EARLY AS
TUESDAY MORNING, BUT MORE LIKELY INTO THE DAY ON TUESDAY.
WARMER-THAN-AVERAGE CONDITIONS WILL CONTINUE INTO THE EARLY PART
OF THE WEEK ACROSS MUCH OF THE CENTRAL TO WESTERN U.S. THE
GREATEST ANOMALIES REMAIN FOCUSED ON THE NORTHERN TO CENTRAL
PLAINS, WHERE HIGHS AS WARM AS THE 60S AND 70S ARE UPWARDS OF
35-40 DEGREES ABOVE EARLY FEBRUARY AVERAGES. SOME DAILY
RECORD-TYING/BREAKING HIGHS MAY BE REACHED MONDAY ACROSS THE
CENTRAL PLAINS. A COLD FRONT WILL BRING CLOSER TO AVERAGE
CONDITIONS FOR PORTIONS OF THE NORTHERN PLAINS MONDAY, WITH HIGHS
IN THE 40S. WHILE NOT QUITE AS ANOMALOUS, CONDITIONS STILL REMAIN
ABOVE AVERAGE ACROSS MUCH OF THE INTERIOR WEST, WITH HIGHS INTO
THE 50S AND 60S, AND ACROSS THE SOUTHERN TIER WITH 70S TO LOW 80S
FROM THE SOUTHERN PLAINS WEST THROUGH THE SOUTHWEST TO SOUTHERN
CALIFORNIA. THE INCOMING PACIFIC SYSTEM WILL KEEP TEMPERATURES
CLOSER TO AVERAGE FOR THE PACIFIC NORTHWEST, NORTHERN CALIFORNIA,
AND NORTHERN GREAT BASIN, WITH HIGHS IN THE 40S AND 50S. IMPROVING
CONDITIONS WILL SPREAD INTO PORTIONS OF THE OHIO/TENNESSEE VALLEYS
AND SOUTHEAST MONDAY, WITH HIGHS INCREASING INTO THE 40S AND 50S
TO THE NORTH AND 60S AND 70S TO THE SOUTH.
