VALID 12Z THU NOV 06 2025 - 12Z SAT NOV 08 2025
...UNSETTLED WEATHER FOR THE PACIFIC NORTHWEST AND NORTHERN
CALIFORNIA, INCLUDING AREAS OF HEAVY RAIN FOR THE COASTAL RANGES
AND HEAVY SNOWFALL OVER THE HIGHER ELEVATIONS OF THE CASCADES
THROUGH EARLY FRIDAY...
...SOME POTENTIAL FOR SEVERE WEATHER WILL EXIST ON FRIDAY ACROSS
PORTIONS OF THE OHIO AND TENNESSEE VALLEYS ON DOWN TO THE CENTRAL
GULF COAST...
...DRY CONDITIONS WILL CONTINUE ACROSS MUCH OF THE SOUTHWEST U.S.
THROUGH THE SOUTHERN PLAINS...
...MUCH COLDER TEMPERATURES TO ARRIVE BY LATE FRIDAY AND SATURDAY
ACROSS THE UPPER MIDWEST...
ACROSS THE CONTINENTAL U.S. THROUGH THIS FRIDAY, THE PRIMARY
WEATHER FEATURES WILL BE A NEW QUICK-HITTING ATMOSPHERIC RIVER IN
THE PACIFIC NORTHWEST AND A NEW SET OF COLD FRONTS MOVING THROUGH
THE MIDWEST/GREAT LAKES AND INTO EASTERN U.S. THE UNSETTLED
WEATHER ACROSS THE PACIFIC NORTHWEST AND NORTHERN CALIFORNIA WILL
BRING COOLER TEMPERATURES AND AREAS OF HEAVY RAINFALL TO THE
COASTAL RANGES. LOCALLY A FEW INCHES OF ADDITIONAL RAINFALL IS
EXPECTED WITH THIS LATEST PACIFIC MOISTURE SURGE, AND WHILE THE
RAINFALL IS EXPECTED TO LARGELY BE BENEFICIAL, THERE MAY BE AN
ISOLATED CONCERN FOR SOME FLOODING. MEANWHILE, AREAS OF HEAVY
ACCUMULATING SNOWFALL ARE EXPECTED FOR THE HIGHER ELEVATIONS OF
THE CASCADES AND ESPECIALLY NORTHERN WASHINGTON WHERE THE HIGH
TERRAIN MAY 12 TO 18+ INCHES THROUGH EARLY FRIDAY. SOME OF THIS
MOISTURE WILL SPILL OVER INTO THE UPSLOPE ARES OF THE NORTHERN
ROCKIES AS THE NEXT PACIFIC FRONT MOVES THROUGH THE INTERMOUNTAIN
REGION, AND THIS WILL BRING SOME LOCALLY HEAVY SNOW HERE AS WELL.
HIGH PRESSURE WILL LARGELY CONTROL THE WEATHER PATTERN ACROSS MUCH
OF THE SOUTHWEST U.S. AND OUT ACROSS THE SOUTHERN PLAINS,
RESULTING IN PLEASANTLY WARM AND DRY CONDITIONS. TEMPERATURES ARE
EXPECTED TO BE ABOVE NORMAL FOR THIS TIME OF YEAR. HOWEVER, BY
FRIDAY, A STRONG COLD FRONT MOVING IN FROM CANADA WILL ALLOW FOR
MUCH COLDER TEMPERATURES TO SURGE INTO PORTIONS OF THE DAKOTAS,
AND ESPECIALLY THE UPPER MIDWEST WHICH WILL SET THE STAGE FOR A
COLD START TO THE WEEKEND WITH BELOW NORMAL TEMPERATURES. LOW
PRESSURE ASSOCIATED WITH THE INCLEMENT WEATHER ACROSS THE WEST
WILL BE EJECTING OUT ACROSS THE NORTHERN PLAINS AND MIDWEST BY
SATURDAY AND THIS WILL SET THE STAGE FOR AT LEAST A SWATH OF LIGHT
SNOWFALL NORTH OF THE LOW TRACK.
FARTHER EAST, IN THE WAKE OF LOW PRESSURE EXITING THE NORTHEAST,
AND A TRAILING COLD FRONT CLEARING MUCH OF THE EAST COAST, HIGH
PRESSURE WILL ALLOW FOR COOLER TEMPERATURES FOR THURSDAY WITH MUCH
OF THE NORTHEAST U.S. IN PARTICULAR SEEING TEMPERATURES BELOW
NORMAL. HOWEVER, ON FRIDAY, A NEW SET OF COLD FRONTS WILL BE
CROSSING THROUGH THE MIDWEST AND MOVING QUICKLY INTO THE EASTERN
U.S. RETURNING MOISTURE AHEAD OF THESE FRONTS WILL SET THE STAGE
FOR SHOWERS AND THUNDERSTORMS TO IMPACT MUCH OF THE OHIO AND
TENNESSEE VALLEY REGION ON DOWN TO THE CENTRAL GULF COAST. RAIN
WILL ALSO OVERSPREAD PORTIONS OF THE GREAT LAKES AND THE
NORTHEAST. THERE MAY BE SOME SEVERE WEATHER FOCUSED ACROSS
PORTIONS OF THE OHIO AND TENNESSEE VALLEYS IN PARTICULAR, AND THE
STORM PREDICTION CENTER HAS DEPICTED A SLIGHT RISK (LEVEL 2/5) OF
SEVERE WEATHER FOR SOUTH-CENTRAL KENTUCKY THROUGH MIDDLE TENNESSEE
WHERE A THREAT FOR LARGE HAIL MAY MATERIALIZE. MORE REGIONALLY,
THERE MAY ALSO BE SOME GUSTY WINDS WITH THE STRONGER THUNDERSTORMS
BEFORE THE COLD FRONT ADVANCES THROUGH THE AREA. THESE
AFOREMENTIONED FRONTS SHOULD ARRIVE ALONG THE EAST COAST BY EARLY
SATURDAY.
