...MODEST ATMOSPHERIC RIVER ACTIVITY TO BRING MULTIPLE ROUNDS OF
BENEFICIAL PRECIPITATION ACROSS THE PACIFIC NORTHWEST AND THE
NORTHERN ROCKIES FOR THE REST OF THE WEEKEND INTO EARLY NEXT
WEEK...
...A ROUND OF MIXED LIGHT RAIN AND SNOW MAY BRUSH THE NORTHERN
BORDERS OF THE NORTHERN PLAINS TO THE UPPER GREAT LAKES SUNDAY TO
MONDAY...
...FAIR AND MILD WEATHER EXPECTED TO CONTINUE FROM THE
SOUTHWESTERN U.S. TO MUCH OF THE EASTERN U.S....
UNSETTLED WEATHER IS EXPECTED TO PREVAIL ACROSS THE NORTHWESTERN
PORTION OF THE COUNTRY AS A SERIES OF FRONTAL SYSTEMS ASSOCIATED
WITH MULTIPLE PACIFIC CYCLONES PUSH TOWARD THE PACIFIC NORTHWEST.
ROUNDS OF MODERATE TO LOCALLY HEAVY PRECIPITATION CAN BE EXPECTED
THROUGH MONDAY AS THESE SYSTEMS MOVE ONSHORE. THE CURRENT ROUND
OF MOSTLY RAIN ACROSS WASHINGTON AND OREGON IS FORECAST TO PUSH
FARTHER INLAND TONIGHT AND BRING HIGH-ELEVATION SNOW AND
LOW-ELEVATION RAIN ACROSS THE NORTHERN ROCKIES ON SUNDAY. AS A
LOW PRESSURE CENTER DEVELOPS OVER THE NORTHERN HIGH PLAINS ON
SUNDAY AND TRACKS TOWARD THE UPPER MIDWEST OF SUNDAY NIGHT, A
ROUND OF MIXED RAIN AND SNOW MAY BRUSH THE NORTHERN BORDERS OF THE
NORTHERN PLAINS TO POSSIBLY THE UPPER GREAT LAKES STARTING SUNDAY
TO MONDAY. RAIN IS EXPECTED TO SPREAD FROM THE UPPER MIDWEST
LATER ON SUNDAY TO MUCH OF THE GREAT LAKES SUNDAY NIGHT, REACHING
INTO WESTERN NEW ENGLAND ON MONDAY. MEANWHILE, THE NEXT SURGE OF
MOISTURE FROM THE PACIFIC WILL REACH THE PACIFIC NORTHWEST LATER
ON SUNDAY AND WILL PERSIST INTO MONDAY. THE LEADING EDGE OF THE
MOISTURE WILL THEN PENETRATE FURTHER INLAND AND BRING THE NEXT
ROUND OF ELEVATION-DEPENDENT RAIN/SNOW ACROSS THE NORTHERN ROCKIES
ON MONDAY.
AS THE UNSETTLED WEATHER CONTINUES OVER THE PACIFIC NORTHWEST,
FAIR AND MILD WEATHER WILL CONTINUE FROM THE SOUTHWESTERN U.S.
THROUGH THE CENTRAL AND SOUTHERN PLAINS AS WELL AS MUCH OF THE
EASTERN U.S. FOR THE NEXT FEW DAYS THANKS TO A RELATIVELY ZONAL
UPPER-LEVEL FLOW ACROSS THE SOUTHERN TIER OF THE COUNTRY.
SHORTWAVE ENERGY BEHIND A FRONT OVER THE SOUTHEAST WILL LEAD TO
AVERAGE TO BELOW AVERAGE TEMPERATURES. SLIGHTLY MILDER THAN
NORMAL TEMPERATURES ARE EXPECTED TO CONTINUE OVER THE PACIFIC
NORTHWEST AS THE UNSETTLED WEATHER PERSISTS.
