A POTENT DISTURBANCE AND STRONG COLD FRONT WILL BRING SNOW TO
PORTIONS OF THE EASTERN GREAT LAKES, INTERIOR NORTHEAST, AND
NORTHERN NEW ENGLAND TUESDAY INTO TUESDAY NIGHT. OVERALL, MOST OF
THE SNOW THAT FALLS IS EXPECTED TO BE LIGHT; HOWEVER, LAKE
ENHANCEMENT WILL RAMP UP THE INTENSITY DOWNWIND OF LAKE ONTARIO
OVER THE TUG HILL PLATEAU, WHERE ACCUMULATIONS HAVE THE POTENTIAL
TO EXCEED 6 INCHES LOCALLY. THE SNOW WILL ALSO BECOME HEAVIER FOR
PARTS OF NORTHERN NEW ENGLAND TUESDAY AFTERNOON, PARTICULARLY
ACROSS NORTHERN MAINE. THERE, MODERATE TO BORDERLINE HEAVY SNOW AT
TIMES WILL LIKELY LEAD TO SLIPPERY ROAD CONDITIONS AND HAZARDOUS
TRAVEL, ESPECIALLY FOR THE TUESDAY EVENING COMMUTE. IN TOTAL,
ACCUMULATIONS OF 4 TO 8 INCHES WITH LOCALLY HIGHER AMOUNTS ARE
EXPECTED FOR MUCH OF NORTHERN MAINE BY THE TIME THE SNOW WRAPS UP
LATE TUESDAY NIGHT.
THE SAME DISTURBANCE AND COLD FRONT THAT WILL BRING SNOW TO PARTS
OF THE NORTHEAST WILL ALSO USHER IN A MUCH COLDER AIR MASS ACROSS
MOST OF THE EASTERN U.S. TUESDAY INTO WEDNESDAY. THE LATE SEASON
BLAST OF CHILLY AIR WILL SEND TEMPERATURES PLUMMETING TO WELL
BELOW SEASONAL AVERAGES. HIGH TEMPERATURES ON TUESDAY WILL TOP OUT
ROUGHLY 10 TO 30 DEGREES BELOW NORMAL, WITH THE COLDEST ANOMALIES
FOUND IN THE NORTHEAST, MID-ATLANTIC, GREAT LAKES, OHIO VALLEY,
AND TENNESSEE VALLEY. TEMPERATURES WON'T BE QUITE AS COOL ACROSS
THE SOUTHEAST U.S, BUT EVEN THERE HIGHS WILL STILL BE AROUND 5 TO
15 DEGREES BELOW NORMAL. TONIGHT, LOW TEMPERATURES WILL DROP TO
NEAR OR BELOW FREEZING FOR MANY, LEADING TO FROST AND FREEZE
CONCERNS IN PLACES WHERE THE GROWING SEASON HAS ALREADY STARTED.
ON WEDNESDAY, TEMPERATURES ACROSS THE EAST WILL MODERATE SOME,
CLIMBING INTO THE 30S, 40S, AND 50S ACROSS THE NORTHEAST U.S. AND
THE 60S AND 70S ACROSS THE SOUTHEAST U.S. AFTER A CHILLY START.
A SERIES OF PACIFIC SYSTEMS WILL CONTINUE TO BRING UNSETTLED
WEATHER TO THE PACIFIC NORTHWEST AND NORTHERN ROCKIES THROUGH
WEDNESDAY, WITH SCATTERED LOWER ELEVATION RAIN SHOWERS AND HIGH
COUNTRY SNOW. MOST OF THE SNOW WILL CONTINUE TO FAVOR THE OLYMPIC
MOUNTAINS AND THE CASCADES WHERE SEVERAL INCHES UP TO A FEW FEET
OF ADDITIONAL ACCUMULATION IS FORECAST. PLENTIFUL CLOUDS AND
PRECIPITATION ASSOCIATED WITH THESE PACIFIC SYSTEMS WILL KEEP
TEMPERATURES ON THE COOLER SIDE OF NORMAL THE NEXT COUPLE OF DAYS
BEFORE TEMPERATURES WARM UP AND CONDITIONS DRY OUT STARTING ON
THURSDAY. FARTHER EAST, A FEW OF THESE DISTURBANCES WILL SURVIVE
THE TRIP OVER THE MOUNTAINS AND BRING RAIN AND/OR SNOW SHOWERS TO
PARTS OF THE UPPER MIDWEST, GREAT LAKES, AND OHIO VALLEY WEDNESDAY
INTO THURSDAY.
A DEVELOPING RIDGE OF HIGH PRESSURE WILL KEEP MUCH OF THE
SOUTHWEST U.S. PRECIPITATION FREE FOR THE NEXT SEVERAL DAYS, WITH
TEMPERATURES TRENDING MUCH WARMER THAN NORMAL THROUGH AT LEAST
MIDWEEK AND LIKELY BEYOND. TEMPERATURE DEPARTURES ROUGHLY 10 TO 30
DEGREES ABOVE AVERAGE WILL BE COMMON, TRANSLATING TO HIGHS IN THE
70S, 80S, AND 90S, WITH SOME DESERT VALLEYS EVEN CRACKING THE
TRIPLE DIGITS. HIGH TEMPERATURES MAY EVEN APPROACH RECORDS
WEDNESDAY AND ESPECIALLY THURSDAY.
