...ACTIVE WINTER WEATHER PATTERN CONTINUES WITH SNOW EXPECTED
ACROSS THE NORTHERN TIER THIS WEEKEND...
..MODERATE TO HEAVY RAINFALL FOR THE GULF COAST LIKELY
...WELL BELOW AVERAGE TEMPERATURES CONTINUE FOR MANY AREAS FROM
THE NORTHERN PLAINS TO THE EAST COAST...
WINTER WEATHER WILL CONTINUE TO MAKE HEADLINES ACROSS MULTIPLE
REGIONS OF THE COUNTRY GOING INTO THE UPCOMING WEEKEND. A PACIFIC
LOW THAT MOVES INLAND ACROSS THE NORTHWEST U.S., AND INTERACTS
WITH AN ARCTIC FRONTAL BOUNDARY THAT WILL BE SITUATED ACROSS THE
NORTHERN ROCKIES THROUGH SATURDAY WILL PRODUCE HEAVY RAIN AND
SNOW. ONE TO TWO FEET OF ACCUMULATION LIKELY FOR THE HIGHER
TERRAIN OF NORTHERN IDAHO TO WESTERN MONTANA, AND THEN EXTENDING
TO THE WASATCH RANGE AND WESTERN WYOMING, AND THE COLORADO
ROCKIES. THERE SHOULD BE SOME ABATEMENT IN THE SNOWFALL BY
SATURDAY NIGHT AS THE LIFT AND MOISTURE EXIT THE REGION. SNOWFALL
BECOMES MORE LIKELY FROM THE DAKOTAS TO IOWA AND SOUTHERN
MINNESOTA BY SATURDAY AFTERNOON INTO EARLY SUNDAY AS THE LOW
PRESSURE SYSTEM REACHES THE MIDWEST STATES. SNOW SHOWERS SPREAD
ACROSS THE MIDWEST, FROM IOWA TO THE NORTHEAST ON SUNDAY.
ELSEWHERE ACROSS THE CONTINENTAL U.S., DRY CONDITIONS ARE EXPECTED
TO CONTINUE FROM CALIFORNIA TO THE SOUTHERN PLAINS, AND EXTENDING
EASTWARD TO THE MID-SOUTH AND TENNESSEE VALLEY. THERE'S POTENTIAL
FOR HIGH WINDS ACROSS CENTRAL WASHINGTON TONIGHT BEHIND A DECAYING
COLD FRONT. PERIODS OF MODERATE TO LOCALLY HEAVY RAINFALL ARE
LIKELY FOR THE LOWER ELEVATIONS OF WESTERN OREGON AND WASHINGTON
THROUGH EARLY SATURDAY AS THE PACIFIC STORM SYSTEM ADVECTS A PLUME
OF MOISTURE INLAND. ACROSS THE GULF COAST REGION, A LINGERING
FRONTAL BOUNDARY OFF THE COAST WILL KEEP RAINFALL CHANCES ELEVATED
THROUGH EARLY SUNDAY FROM SOUTHEAST LOUISIANA TO THE FLORIDA
PENINSULA TO SOUTHERN SOUTH CAROLINA, WITH SOME 1 INCH TOTALS
POSSIBLE IN SOME AREAS. IN TERMS OF TEMPERATURES, IT WILL BE QUITE
COLD FROM THE NORTHERN PLAINS TO THE NORTHEAST WITH A BIG DIP IN
THE JET STREAM AND MULTIPLE COLD FRONTAL PASSAGES HERALDING THE
ARRIVAL OF A POLAR AIRMASS. SOME SUBZERO OVERNIGHT LOWS ARE LIKELY
ACROSS PORTIONS OF THE DAKOTAS AND INTO MINNESOTA, ESPECIALLY BY
SUNDAY MORNING IN THE WAKE OF THE NEXT ARCTIC FRONT.
