...WINTER WEATHER POSSIBLE FOR THE RETURN FROM THE THANKSGIVING
HOLIDAY FROM PORTIONS OF THE SOUTHERN TO CENTRAL PLAINS INTO THE
MID TO UPPER MISSISSIPPI VALLEY AND WESTERN LAKES REGION..
...RAIN POSSIBLE ALONG THE GULF COAST AND THE NORTHERN
MID-ATLANTIC TO NEW ENGLAND COASTS...
...BELOW AVERAGE TEMPERATURES TO SPREAD EASTWARD FROM THE PLAINS
INTO THE MISSISSIPPI AND OHIO VALLEY REGION FOR THE START OF THE
WORK WEEK...
...TRANQUIL WEATHER ON TAP FROM THE HIGH PLAINS, WEST TO THE WEST
COAST...
THE LAST PART OF THE RETURN TRIP FROM THE THANKSGIVING HOLIDAY
WILL BRING THE POTENTIAL FOR ACCUMULATING SNOWS AND TRAVEL
DISRUPTIONS FROM PORTIONS OF THE CENTRAL TO SOUTHERN PLAINS,
NORTHEASTWARD INTO THE MID TO UPPER MISSISSIPPI VALLEY AND WESTERN
GREAT LAKES. THIS IS IN RESPONSE TO AN UPPER LEVEL LOW, THAT HAS
ALREADY PRODUCED WIDESPREAD HEAVY SNOWS ACROSS THE NORTHERN TO
CENTRAL ROCKIES, PUSHING NORTHEASTWARD FROM THE CENTRAL PLAINS
INTO THE GREAT LAKES AND A MORE NORTHERN AREA OF LOW PRESSURE
MOVING ALONG THE SOUTH CENTRAL CANADA/NORTH CENTRAL U.S. BORDER
AREA INTO THE GREAT LAKES. SNOWFALL AMOUNTS ARE EXPECTED TO BE
LIGHTER THAN WHAT FELL THROUGH THE NORTHERN AND CENTRAL ROCKIES,
WITH ACCUMULATIONS GENERALLY IN THE 2 TO 4 INCH RANGE. TRAVEL
DISRUPTIONS ALSO POSSIBLE ALONG THE IMMEDIATE GULF COAST FROM
TEXAS TO FLORIDA AS RAINFALL IS EXPECTED TO DEVELOP ACROSS THIS
REGION ON SUNDAY. STORMY WEATHER ALSO POSSIBLE LATE SUNDAY INTO
EARLY MONDAY FROM THE NORTHERN MID ATLANTIC COAST, NORTHEASTWARD
ALONG THE NEW ENGLAND COAST AS AN AREA OF LOW PRESSURE DEEPENS
ACROSS THIS AREA. THIS MAY PRODUCE SOME MODERATE TO LOCALLY HEAVY
PRECIPITATION TOTALS, BUT TEMPERATURES ARE EXPECTED TO BE WARM
ENOUGH TO KEEP THE PRECIPITATION AS RAIN.
IN THE WAKE OF THE SYSTEM PUSHING NORTHEASTWARD FROM THE PLAINS
INTO THE GREAT LAKES, BELOW AVERAGE TEMPERATURES WILL BE SPREADING
EASTWARD SUNDAY INTO MONDAY FROM THE PLAINS INTO THE MISSISSIPPI
AND OHIO VALLEY REGIONS. THIS COLD AIR WILL THEN PUSH INTO THE
EASTERN U.S. BY TUESDAY. AS THE COLD AIR PUSHES ACROSS THE GREAT
LAKES LATE SUNDAY INTO MONDAY, LAKE EFFECT SNOW SHOWERS WILL
DEVELOP FROM WEST TO EAST IN THE LEE OF THE GREAT LAKES. THIS
WILL SUPPORT LOCALLY HEAVY SNOWFALL AMOUNTS ACROSS THE FAVORED
LAKE EFFECT SNOW REGIONS OF THE UPPER PENINSULA OF MICHIGAN, THE
WESTERN PORTIONS OF THE LOWER PENINSULA OF MICHIGAN AND FROM FAR
NORTHEAST OHIO, FAR NORTHWEST PENNSYLVANIA INTO FAR WESTERN NEW
YORK STATE AND NORTHERN NEW YORK STATE.
MEANWHILE, MOSTLY TRANQUIL WEATHER EXPECTED FROM THE HIGH PLAINS,
WESTWARD THROUGH THE ROCKIES AND TO THE WEST COAST AS HIGH
PRESSURE WILL REMAIN CENTERED ACROSS THE CENTRAL ROCKIES AND
PROVIDE FOR DRY WEATHER. THE CLEAR SKIES AND DRY WEATHER WILL
BRING THE POTENTIAL FOR FREEZING TEMPERATURES OVER THE NEXT FEW
MORNINGS THROUGH THE INTERIOR VALLEYS OF CALIFORNIA WHERE FREEZE
WARNINGS ARE IN EFFECT FOR SUNDAY MORNING.
