...DANGEROUS ARCTIC AIRMASS WILL PERSIST OVER THE EASTERN GREAT
LAKES, OHIO VALLEY, MID-ATLANTIC AND NORTHEAST THROUGH SUNDAY...
...LOWER ELEVATION RAIN AND HIGHER ELEVATION SNOW CONTINUES FOR
THE PACIFIC NORTHWEST TO THE NORTHERN ROCKIES SUNDAY...
...WARMER-THAN-AVERAGE TEMPERATURES CONTINUE FOR MUCH OF THE
CENTRAL TO WESTERN U.S....
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 SUNDAY.
FORECAST HIGHS RANGE FROM THE SINGLE DIGITS AND TEENS FOR THE
INTERIOR NORTHEAST/NEW ENGLAND TO THE 20S AND 30S FURTHER SOUTH
INTO THE OHIO VALLEY AND MID-ATLANTIC. 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.
A PACIFIC SYSTEM AND ACCOMPANYING INFLUX OF MOISTURE WILL CONTINUE
TO OVERSPREAD THE PACIFIC NORTHWEST EAST THROUGH THE NORTHERN
GREAT BASIN AND ROCKIES SUNDAY. THE FOCUS FOR THE HEAVIEST
RAINFALL WILL SHIFT SOUTHWARD FROM WESTERN WASHINGTON TO WESTERN
OREGON/FAR NORTHERN CALIFORNIA TODAY, WITH LIGHT TO MODERATE RAIN
SHOWERS FOR LOWER ELEVATIONS/VALLEYS INLAND THROUGH THE NORTHERN
GREAT BASIN/ROCKIES. COOLING TEMPERATURES AS A COLD FRONT SINKS
SOUTH SUNDAY NIGHT INTO MONDAY MAY LEAD TO A WINTRY MIX FOR SOME
LOWER ELEVATION LOCATIONS, 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.
ELSEWHERE, ANOTHER CLIPPER-LIKE SYSTEM MOVING ALONG THE
U.S./CANADIAN BORDER WILL BRING WINTRY PRECIPITATION CHANCES TO
THE UPPER GREAT LAKES MONDAY, WITH SOME LIGHT ICING AND SNOW
SHOWERS EXPECTED. THIS SYSTEM IS ALSO EXPECTED TO BRING SOME MORE
MODERATE SNOWFALL CHANCES INTO UPSTATE NEW YORK/NEW ENGLAND
TUESDAY. INCREASING MOISTURE AHEAD OF A COLD FRONT MOVING THROUGH
THE OHIO/TENNESSEE VALLEYS SOUTHWEST THROUGH THE MISSISSIPPI
VALLEY INTO THE SOUTHERN PLAINS WILL BRING INCREASING SHOWER AND
THUNDERSTORM CHANCES 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 NEXT 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 ALSO SPREAD EAST INTO THE MISSISSIPPI VALLEY TODAY
AND THEN 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.
