...ANOTHER STORM TO BRING ADDITIONAL HEAVY SNOWS TO NORTHERN
CALIFORNIA AND SOUTHERN OREGON...
...A WET WEATHER PATTERN FOR LARGE AREAS TO THE EAST OF THE
MISSISSIPPI RIVER...
..MUCH ABOVE AVERAGE TEMPERATURES EXPECTED FOR MUCH OF THE LOWER
48 TO THE EAST OF THE ROCKIES OVER THE NEXT FEW DAYS...
...RECORD HIGH EARLY MORNING LOWS POSSIBLE FROM THE LOWER
LAKES/OHIO VALLEY INTO THE NORTHEAST...
AN AREA OF LOW PRESSURE OFF THE NORTHERN CALIFORNIA/PACIFIC
NORTHWEST COAST WILL BE MOVING SLOWLY SOUTHEASTWARD TUESDAY AND
WEDNESDAY TO A POSITION OFF THE CENTRAL TO SOUTHERN CALIFORNIA
COAST. THIS STORM WILL BE SPREADING ADDITIONAL MODERATE TO HEAVY
PRECIPITATION AMOUNTS INTO NORTHERN CALIFORNIA AND SOUTHWESTERN
OREGON OVER THE NEXT TWO DAYS, WITH THE POTENTIAL FOR ADDITIONAL
SNOWFALL TOTALS OF 1 TO 2 FEET FROM THE SOUTHERN OREGON CASCADES
INTO THE NORTHERN SIERRA. WHILE THESE TOTALS WILL BE MUCH LESS
THAN THE PREVIOUS MORE LONG LASTING STORM, TRAVEL WILL REMAIN
DIFFICULT AND THE ADDITIONAL HEAVY SNOWS WILL EXACERBATE RECOVERY
FROM THE FIRST STORM. WINTER STORM WARNINGS ARE IN EFFECT FOR
THE NORTHERN SIERRA, NORTHERN CALIFORNIA COAST RANGE AND INTO
SOUTHERN OREGON FOR ADDITIONAL HEAVY SNOW AMOUNTS. THE GOOD NEWS
FOR THIS AREA OF THE COUNTRY IS THAT AFTER THE NEXT ROUND OF HEAVY
SNOWS, MORE TRANQUIL WEATHER IS EXPECTED FOR THE REMAINDER OF THE
WEEK.
A WET WEATHER PATTERN IS IN STORE FOR LARGE AREAS OF THE LOWER 48
TO THE EAST OF THE MISSISSIPPI RIVER OVER THE NEXT FEW DAYS. THIS
WILL BE ALONG AND TO THE EAST OF A SLOW MOVING FRONTAL BOUNDARY
STRETCHING SOUTHWEST TO NORTHEAST FROM THE SOUTHERN PLAINS INTO
THE MID MISSISSIPPI VALLEY, OHIO VALLEY AND INTO THE NORTHEAST AND
AHEAD OF TWO AREAS OF LOW PRESSURE MOVING FROM THE CENTRAL GULF
COAST UP ALONG THE EAST COAST. MOISTURE VALUES EXPECTED TO BE
MUCH ABOVE AVERAGE ALONG AND TO THE EAST OF THIS FRONT AND AHEAD
OF THE TWO AREAS OF LOW PRESSURE MOVING ALONG THE EAST COAST,
SUPPORTING THE POTENTIAL FOR WIDESPREAD REGIONS OF PRECIPITATION.
THE HEAVIEST RAINFALL TOTALS EXPECTED FROM THE CENTRAL GULF COAST,
ACROSS PORTIONS OF THE SOUTHEAST AND MID-ATLANTIC WHERE THE TWO
AREAS OF LOW PRESSURE ARE EXPECTED TO MOVE ACROSS. THE LEAD AREA
OF LOW PRESSURE WILL SPREAD RAINS ACROSS THE MID-ATLANTIC MONDAY
NIGHT AND INTO THE NORTHEAST ON TUESDAY. THIS WILL BE FOLLOWED BY
ANOTHER LOW MOVING FROM THE CENTRAL GULF COAST TUESDAY NIGHT, INTO
THE SOUTHEAST WEDNESDAY AND THE MID-ATLANTIC WEDNESDAY NIGHT.
RAINFALL TOTALS OF 1 TO 2 INCHES POSSIBLE ACROSS THESE REGIONS,
WITH ISOLATED AREAS OF FLASH FLOODING POSSIBLE, ESPECIALLY IN
URBANIZED AREAS OF THE CENTRAL GULF COAST.
MUCH ABOVE AVERAGE, SPRING LIKE TEMPERATURES WILL PERSIST FOR MUCH
OF THE WEEK FOR AREAS TO THE EAST OF THE ROCKIES. MANY AREAS WILL
SEE HIGH TEMPERATURES TUESDAY AND WEDNESDAY 15 TO 25+ DEGREES
ABOVE AVERAGE. THE WARMEST TEMPERATURES ARE EXPECTED ACROSS THE
SOUTHERN PLAINS INTO THE LOWER MISSISSIPPI VALLEY WHERE WIDESPREAD
HIGHS IN THE 70S AND 80S ARE FORECAST. THERE ARE NOT EXPECTED TO
BE ANY RECORD HIGH TEMPERATURES ACROSS THESE AREAS OVER THE FEW
DAYS, HOWEVER, THERE IS POTENTIAL FOR WIDESPREAD RECORD HIGH
MORNING LOW TEMPERATURES FROM THE LOWER GREAT LAKES INTO THE
NORTHEAST WHERE THE ABOVE MENTIONED MUCH ABOVE AVERAGE MOISTURE
VALUES WILL KEEP TEMPERATURES FROM COOLING AT NIGHT. BELOW TO MUCH
BELOW AVERAGE TEMPERATURES ARE EXPECTED FROM THE NORTHERN HIGH
PLAINS, NORTHERN ROCKIES, PACIFIC NORTHWEST AND NORTHERN
CALIFORNIA. ACROSS THESE REGIONS, HIGH TEMPERATURES ARE EXPECTED
TO BE APPROXIMATELY 10 TO 20 DEGREES COLDER THAN AVERAGE ON
TUESDAY AND WEDNESDAY.
