...COASTAL STORM TO BRING RAIN AND MAYBE SOME WET SNOW ACROSS
PORTIONS OF THE CAROLINAS SUNDAY MORNING...

...MUCH COLDER TEMPERATURES TO ARRIVE INTO THE NORTH-CENTRAL U.S.
SUNDAY INTO MONDAY ALONG WITH BLIZZARD CONDITIONS AT TIMES...

...WARMING TREND EXPECTED ALONG THE WEST COAST INTO EARLY NEXT
WEEK WHILE REMAINING DRY...

A DEVELOPING FRONTAL SYSTEM JUST EAST OF THE FLORIDA PENINSULA
WILL BY ACCOMPANIED BY A STRENGTHENING SURFACE LOW TONIGHT INTO
EARLY SUNDAY. THE SURFACE LOW IS EXPECTED TO TRACK CLOSE ENOUGH TO
THE SOUTHEAST COAST OF THE U.S. WHERE IT WILL BRING LOCALLY HEAVY
RAIN TO EASTERN NORTH AND SOUTH CAROLINA BEGINNING OVERNIGHT
TONIGHT. AS THE STORM STRENGTHENS, SOME WET SNOW AND MINOR
ACCUMULATIONS COULD DEVELOP OVER PORTIONS OF THE CAROLINAS EARLY
SUNDAY MORNING. ANY ACCUMULATIONS SHOULD BE MINOR, BUT WINDS WILL
BECOME GUSTY DURING THE DAY ON SUNDAY ALONG THE ENTIRE SOUTHEAST
COAST. AS THE SURFACE LOW ADVANCES INTO SUNDAY NIGHT AND EARLY
MONDAY MORNING, IT IS EXPECTED TO CLIP SOUTHEAST NEW ENGLAND WITH
A FEW INCHES OF SNOWFALL WHILE THE HEAVIEST SNOW STAYS OUT OVER
THE ATLANTIC.

A DEEP SURFACE LOW WILL TRACK ACROSS THE UPPER MISSISSIPPI VALLEY
ON SUNDAY, WITH A COLD FRONT TRAILING TO ITS SOUTHWEST. IT IS
ACTUALLY A SECONDARY COLD FRONT THAT WILL USHER IN MUCH COLDER
TEMPERATURES FOR THE NORTH-CENTRAL U.S. BY LATE IN THE DAY IN
SUNDAY. TEMPERATURES DEPARTURES FROM NORMAL HIGHS ARE EXPECTED TO
DROP FROM +25 TODAY TO -10 FOR MONDAY. IN ADDITION, WINDS WILL
STRENGTHEN THROUGH TONIGHT AND SPREAD SOUTHEASTWARD ACROSS THE
REGION ON SUNDAY ALONG WITH SNOW SHOWERS. WHILE SNOW ACCUMULATIONS
WILL BE LIGHT, THE COMBINATION OF FALLING TEMPERATURES, BLOWING
SNOW AND GUSTY WINDS WILL MAKE FOR BLIZZARD CONDITIONS AT TIMES,
FORCING TRAVEL TO BE HAZARDOUS.

ACROSS THE WESTERN U.S., A LARGE UPPER LEVEL RIDGE WILL DEVELOP
OVER THE ENTIRE REGION, GIVEN A REPRIEVE FROM RECENT WET/SNOWY
WEATHER. THE UPPER RIDGE WILL PREVENT RAIN/SNOW FROM IMPACTING THE
WEST, WHILE ALSO ENSURING WARMING TEMPERATURES THROUGH MONDAY.
HIGH TEMPERATURES FOR SUNDAY AND MONDAY ARE FORECAST TO BE BETWEEN
5 AND 15 DEGREES ABOVE AVERAGE FROM WESTERN WASHINGTON TO SOUTHERN
CALIFORNIA AND SOUTHWESTERN ARIZONA.
