...SLOW MOVING STORM TO PUSH EAST FROM SOUTHERN CALIFORNIA INTO
THE SOUTHWEST...
...LOCALLY HEAVY SNOWS EXPECTED ACROSS THE GREAT LAKES INTO
PORTIONS OF THE NORTHEAST AND NEW ENGLAND...
...ABOVE AVERAGE TEMPERATURES EXPECTED ACROSS MUCH OF THE CENTRAL
TO EASTERN U.S., WHILE BELOW AVERAGE TEMPERATURES STRETCH FROM
SOUTHERN CALIFORNIA INTO THE SOUTHWEST...
A SLOW MOVING UPPER LOW THAT BROUGHT SOME MUCH NEEDED
PRECIPITATION TO SOUTHERN CALIFORNIA OVER THE WEEKEND WILL BE
PUSHING SLOWLY EASTWARD OVER THE NEXT FEW DAYS FROM SOUTHERN
CALIFORNIA THROUGH THE SOUTHWEST. THIS SYSTEM, HOWEVER, WILL
BECOME INCREASINGLY MOISTURE STARVED OVER THE NEXT FEW DAYS AS IT
PUSHES INTO THE SOUTHWEST. SUBSEQUENTLY, PRECIPITATION AMOUNTS
ARE EXPECTED TO BE LIGHTER OVER THE SOUTHWEST TUESDAY-WEDNESDAY
THAN WHAT WAS OBSERVED OVER SOUTHERN CALIFORNIA THIS PAST WEEKEND.
THIS PRECIPITATION OVER THE SOUTHWEST WILL BRING LITTLE IN THE
WAY OF RELIEF TO THE ONGOING DROUGHT CONDITIONS OVER ARIZONA AND
NEW MEXICO. THERE WILL BE POTENTIAL FOR MORE WIDESPREAD HEAVY
PRECIPITATION WITH THIS SYSTEM LATE WEDNESDAY INTO THURSDAY ACROSS
THE SOUTHERN PLAINS INTO THE LOWER ARKANSAS VALLEY AS HIGH
MOISTURE VALUES FEED INTO THIS SYSTEM FROM OFF THE WESTERN GULF.
THIS SLOW MOVING UPPER LOW WILL KEEP TEMPERATURES BELOW AVERAGE ON
TUESDAY FROM SOUTHERN CALIFORNIA INTO ARIZONA, WITH THESE BELOW
AVERAGE TEMPERATURES SPREADING EAST INTO MUCH OF NEW MEXICO ON
WEDNESDAY.
IN CONTRAST TO THE BELOW AVERAGE TEMPERATURES ACROSS SOUTHERN
CALIFORNIA INTO THE SOUTHWEST, TEMPERATURES ARE EXPECTED TO REMAIN
WELL ABOVE AVERAGE OVER THE NEXT FEW DAYS ACROSS MUCH OF THE
CENTRAL TO EASTERN U.S. HIGH TEMPERATURES ARE FORECAST TO BE 10
TO 20+ DEGREES ABOVE AVERAGE OVER THESE REGIONS TUESDAY AND
WEDNESDAY. DESPITE THE WIDESPREAD MUCH ABOVE AVERAGE TEMPERATURES
EXPECTED ACROSS THE CENTRAL TO EASTERN U.S., THERE ARE NOT
EXPECTED TO BE MANY RECORD HIGH TEMPERATURES, WITH ONLY A FEW
FORECAST ACROSS SOUTH DAKOTA, NORTH DAKOTA AND IOWA ON TUESDAY.
MORE TYPICAL WINTRY WEATHER ON TAP ACROSS THE GREAT LAKES INTO
PORTIONS OF NEW YORK STATE AND NEW ENGLAND OVER THE NEXT FEW DAYS
AS TWO WINTER SYSTEM AFFECT THIS REGION. THE INITIAL SYSTEM WILL
BE A STRONG COLD FRONT DROPPING SOUTHEASTWARD THROUGH THE GREAT
LAKES MONDAY NIGHT AND THROUGH NEW ENGLAND EARLY TUESDAY. SNOW
SQUALLS ARE POSSIBLE ALONG AND AHEAD OF THIS STRONG FRONT FROM THE
GREAT LAKES INTO THE NORTHEAST, PRODUCING INTENSE SHORT TERM
SNOWFALL, ALONG WITH GUSTY WINDS, POOR VISIBILITY AND DANGEROUS
DRIVING CONDITIONS. THIS WILL THEN BE FOLLOWED BY AN AREA OF LOW
PRESSURE PUSHING SOUTHEASTWARD FROM THE UPPER GREAT LAKES TUESDAY
AFTERNOON INTO NORTHERN NEW YORK STATE AND NEW ENGLAND ON
WEDNESDAY. THIS LOW WILL BRING THE POTENTIAL FOR ACCUMULATING
SNOWS FROM THE UPPER PENINSULA OF MICHIGAN, THE NORTHERN PORTIONS
OF THE LOWER PENINSULA OF MICHIGAN, MUCH OF WESTERN TO NORTHERN
NEW YORK STATE, WESTERN MASSACHUSETTS, INTO MUCH OF VERMONT AND
NEW HAMPSHIRE.
