...STORM SYSTEM TO BRING SNOW TO THE FOUR CORNERS REGION AS WELL
AS WIDESPREAD SHOWERS AND THUNDERSTORMS FROM THE PLAINS TO THE
MIDWEST/MISSISSIPPI VALLEY THURSDAY...
...FLASH FLOODING AND SEVERE WEATHER THREAT ACROSS THE LOWER
MISSISSIPPI AND TENNESSEE VALLEYS FRIDAY...
...HEAVY MOUNTAIN SNOW CONTINUES FOR THE CASCADES AS WELL AS
PORTIONS OF THE INTERIOR WEST THROUGH THURSDAY...
...WELL ABOVE AVERAGE TEMPERATURES CONTINUE FOR MUCH OF THE
CENTRAL AND EASTERN U.S. WHILE THE WESTERN U.S. TRENDS CHILLIER...
AN UPPER-WAVE DROPPING SOUTHWARD ALONG THE WEST COAST OVERNIGHT
WILL SWING EASTWARD OVER THE SOUTHWEST THIS MORNING. MOISTURE
AHEAD OF THE SYSTEM WILL BEGIN TO FIRST SPREAD INTO THE DESERT
SOUTHWEST, BRINGING SHOWERS AND THUNDERSTORMS, BEFORE SNOW BEGINS
SPREADING THROUGH THE MOUNTAINS OF THE FOUR CORNERS REGION BY
WEDNESDAY NIGHT. MODERATE TO LOCALLY HEAVY SNOWFALL IS EXPECTED
ESPECIALLY OVERNIGHT WEDNESDAY AND INTO THURSDAY AS THE UPPER-WAVE
PASSES OVERHEAD AND A SECOND UPPER WAVE QUICKLY DROPS SOUTHWARD
BEHIND IT. MEANWHILE, LEE CYCLOGENESIS IS EXPECTED AS THE
UPPER-WAVE REACHES THE PLAINS OVERNIGHT WEDNESDAY, HELPING TO
ORGANIZE A LOW PRESSURE/FRONTAL SYSTEM OVER THE CENTRAL/SOUTHERN
PLAINS. INCREASING MOIST, SOUTHERLY FLOW FROM THE GULF AHEAD OF
THE SYSTEM WILL LEAD TO AN EXPANDING AREA OF SHOWERS AND
THUNDERSTORMS FROM THE CENTRAL/SOUTHERN PLAINS THURSDAY MORNING
INTO THE MIDWEST/MISSISSIPPI VALLEY THROUGHOUT THE DAY. RAINFALL
SHOULD GENERALLY REMAIN MODEST. HOWEVER, AS THE SYSTEM MOVES INTO
THE LOWER MISSISSIPPI AND TENNESSEE VALLEYS FRIDAY, MUCH HEAVIER
RAINFALL IS EXPECTED, WITH SCATTERED FLASH FLOODING POSSIBLE, AS
WELL AS A SEVERE WEATHER THREAT. SOME WINTRY PRECIPITATION WILL BE
POSSIBLE IN THE COLDER AIR TO THE NORTHWEST OF THE LOW-TRACK,
GENERALLY FROM NEBRASKA NORTHEAST INTO THE UPPER MIDWEST, THOUGH
LITTLE TO NO ACCUMULATIONS ARE EXPECTED. THE MORE IMPACTFUL WINTER
WEATHER WILL BE IN THE POST-FRONTAL UPSLOPE FLOW ALONG THE FRONT
RANGE OF THE ROCKIES. ACCUMULATIONS OF SEVERAL INCHES ARE POSSIBLE
THURSDAY INTO FRIDAY FOR PORTIONS OF SOUTHERN COLORADO INTO
NORTHEASTERN NEW MEXICO, AND POSSIBLY EAST INTO SOUTHWESTERN
KANSAS AND THE OKLAHOMA PANHANDLE AS WELL.
VERY HEAVY SNOW WILL CONTINUE FOR THE MOUNTAINS OF THE PACIFIC
NORTHWEST INCLUDING THE CASCADES AND OLYMPICS AS ONE PACIFIC
SYSTEM PASSES THROUGH AND A SECOND APPROACHES DURING THE DAY
WEDNESDAY. AT LEAST 1-2 MORE FEET OF SNOW IS POSSIBLE BRINGING
STORM TOTAL SNOWFALL INTO THE 3-4 FOOT RANGE. THE SYSTEM PASSAGES
AND INLAND FLOW OF MOISTURE WILL ALSO CONTINUE TO BRING MODERATE
TO HEAVY SNOW TO THE MOUNTAIN RANGES OF THE NORTHERN/CENTRAL
ROCKIES AND GREAT BASIN, AS WELL AS SOUTHWARD INTO PORTIONS OF
NORTHERN CALIFORNIA AND THE SIERRA. MODERATE RAINFALL WILL ALSO
CONTINUE FOR COASTAL/LOWER ELEVATIONS OF THE PACIFIC NORTHWEST, AS
WELL AS A LIGHTER WINTRY MIX FURTHER INLAND ACROSS LOWER
ELEVATIONS OF THE GREAT BASIN. PRECIPITATION SHOULD TREND DOWNWARD
INTO THURSDAY BEFORE COMING TO AN END FOR MOST LOCATIONS BY
FRIDAY. ELSEWHERE, SOME LIGHT ICING AND SNOW WILL LINGER FOR
PORTIONS OF NEW ENGLAND TODAY AS AN AREA OF LOW PRESSURE LIFTS
AWAY FROM THE REGION INTO THE ATLANTIC.
AMPLIFYING UPPER-RIDGING WILL KEEP WELL ABOVE AVERAGE TEMPERATURES
IN THE FORECAST FOR MUCH OF THE CENTRAL TO EASTERN U.S. THIS WEEK.
THE TREND WILL BE FOR THE GREATEST ANOMALIES OF 25-35 DEGREES AS
WELL AS POTENTIAL FOR A HANDFUL OF RECORD-TYING/BREAKING DAILY
HIGHS TO SHIFT EASTWARD FROM THE PLAINS WEDNESDAY TO THE
MISSISSIPPI VALLEY/MIDWEST THURSDAY. THIS ALSO INCLUDES A WARM-UP
INTO ABOVE AVERAGE HIGHS FOR THE NORTHEAST FOLLOWING A CHILLY
PATTERN TO START THE YEAR. FORECAST HIGHS GENERALLY RANGE IN THE
30S AND 40S FROM THE NORTHERN PLAINS EAST THROUGH THE GREAT LAKES
AND INTO NEW ENGLAND; THE 40S AND 50S FOR THE MID-ATLANTIC; THE
50S AND 60S FROM THE CENTRAL PLAINS EAST THROUGH THE MIDDLE
MISSISSIPPI/OHIO VALLEYS; AND THE 60S, 70S, AND SOME 80S FROM THE
SOUTHERN PLAINS/TEXAS EAST THROUGH THE SOUTHEAST. IN CONTRAST,
MULTIPLE COLD FRONT PASSAGES WILL BRING COLDER TEMPERATURES TO
MOST OF THE WEST FOLLOWING A MILD WEEKEND AND START TO THE WEEK.
BELOW AVERAGE CONDITIONS WILL BEGIN TO SPREAD EASTWARD FROM THE
WEST COAST WEDNESDAY AND ESPECIALLY INTO THURSDAY, WHEN HIGHS WILL
RANGE IN THE 30S AND 40S FOR THE PACIFIC NORTHWEST/INTERIOR WEST,
THE 50S AND 60S FOR CALIFORNIA, AND THE 60S FOR THE DESERT
SOUTHWEST.
