...RAIN OVER PARTS OF THE NORTHWEST THIS WEEKEND ALONG WITH
INCREASING WINDS OVER INTERIOR PORTIONS OF THE NORTHWEST...
..WARM AND DRY FOR MANY ACROSS THE LOWER 48
A LARGE UPPER LEVEL LOW/TROUGH WILL MOVE INTO THE NORTHWESTERN
U.S. THIS WEEKEND, BRINGING RAIN TO THE PACIFIC NORTHWEST TONIGHT
INTO SATURDAY MORNING AND CONTINUING THROUGH THE WEEKEND. RAINFALL
INTENSITY WILL VARY OVER THE NEXT TWO DAYS BUT TOTAL RAINFALL
THROUGH SUNDAY OF 2 TO 4 INCHES ACROSS THE COASTAL RANGES AND
CASCADES (LOCALLY HIGHER) WILL BE BENEFICIAL AS MUCH OF THE REGION
HAS BEEN DRIER THAN AVERAGE OVER THE PAST MONTH. SNOW WILL BE
LIMITED TO THE HIGHEST ELEVATIONS OF THE OLYMPICS AND
WASHINGTON/OREGON CASCADES, AT LEAST THROUGH SUNDAY MORNING,
BEFORE COLDER AIR FILTERS IN FOR THE LATTER HALF OF SUNDAY.
EXCLUDING THE NORTHWEST, OUTSIDE OF A FEW SHOWERS AND
THUNDERSTORMS FROM THE OZARKS TO THE CENTRAL APPALACHIANS AND
SOUTHERN MID-ATLANTIC NEAR A PROGRESSIVE COLD FRONT, MUCH OF THE
LOWER 48 WILL REMAIN WARM AND DRY THROUGH SUNDAY. THIS WILL BE DUE
TO A LACK OF HIGHER ATMOSPHERIC MOISTURE AND THE STABILIZING
INFLUENCE OF HIGH PRESSURE FROM THE GREAT PLAINS TO THE EAST
COAST. LOCATIONS TO THE SOUTH OF THE PROGRESSIVE COLD FRONT, FROM
THE SOUTHEAST INTO TEXAS, AS WELL AS PORTIONS OF THE SOUTHWEST,
WILL SEE HIGH TEMPERATURES OF 10 TO 20 DEGREES ABOVE LATE OCTOBER
AVERAGES THIS WEEKEND. HIGHS IN THE UPPER 80S TO LOWER 90S ACROSS
THE DEEP SOUTH MAY BREAK A FEW DAILY HIGH TEMPERATURE RECORDS.
FARTHER NORTH, WHILE NOT EXPECTED TO BE RECORD BREAKING WARMTH,
ANOMALOUS HIGH TEMPERATURES OF 15 TO 25 DEGREES ABOVE AVERAGE WILL
FOCUS FROM THE CENTRAL TO NORTHERN HIGH PLAINS THIS WEEKEND WITH
DOWNSLOPING WINDS ALOFT. IN ADVANCE OF THE STORM SYSTEM TO IMPACT
THE NORTHWEST, SOME OF THESE WINDS WILL BE GUSTY ACROSS INTERIOR
PORTIONS OF THE NORTHWEST TO NORTH-CENTRAL U.S., ESPECIALLY IN THE
LEE OF THE NORTHERN ROCKIES IN MONTANA WHERE A HIGH WIND WATCH IS
IN EFFECT FOR SUNDAY WITH WIND GUSTS OF 55 TO 70 MPH POSSIBLE.
ONE EXCEPTION TO THE WARM AND DRY CONDITIONS FOR MUCH OF THE
NATION WILL BE SOUTHEAST OF LAKES ERIE AND ONTARIO WHERE LAKE
EFFECT SHOWERS WILL KEEP TEMPERATURES COOLER THAN AVERAGE BEHIND A
SERIES OF COLD FRONTS. NORTHERN NEW ENGLAND WILL ALSO SEE SHOWERS
UNDER THE INFLUENCE OF UPPER TROUGHING AND A SERIES OF COLD
FRONTS. SOME SNOW MIXING IN WILL ALSO BE POSSIBLE FOR SATURDAY
NIGHT INTO SUNDAY FROM THE ADIRONDACKS INTO NORTHERN VERMONT, NEW
HAMPSHIRE AND MAINE.
COOLER THAN AVERAGE TEMPERATURES WILL ALSO EXTEND SOUTHWARD INTO
THE MID-ATLANTIC REGION, BUT CONDITIONS WILL REMAIN DRY FOR THESE
SOUTHERN LOCATIONS. A FEW LAKE EFFECT SHOWERS ARE ALSO EXPECTED
FOR THE EASTERN U.P. OF MICHIGAN AND NORTHERN LOWER MICHIGAN THIS
WEEKEND BUT TEMPERATURES WILL BE A LITTLE ABOVE AVERAGE THROUGH
SUNDAY.
