VALID 00Z FRI NOV 10 2023 - 00Z SUN NOV 12 2023
...AFTER A PERIOD OF ABOVE AVERAGE TO RECORD BREAKING WARMTH,
COLDER TEMPERATURES TO FILTER SOUTH AND EAST ACROSS THE EASTERN
AND SOUTHEASTERN U.S. THROUGH THE END OF THE WEEK...
...LOCALLY HEAVY RAIN AT TIMES FROM EASTERN TO SOUTHERN TEXAS
THROUGH THROUGH AT LEAST FRIDAY MORNING...
...RAIN AND SNOW TO IMPACT THE NORTHWESTERN U.S. WITH THE HEAVIEST
PRECIPITATION ACROSS WESTERN WASHINGTON...
...CRITICAL RISK OF WILDFIRES OVER PARTS OF SOUTHERN CALIFORNIA
TODAY, DIMINISHING THROUGH FRIDAY MORNING...
A COLD FRONT EXTENDING FROM THE NORTHEAST TO TEXAS WILL CONTINUE
TO BE FOLLOWED BY MUCH COOLER TEMPERATURES IN ITS WAKE. HIGH
TEMPERATURES WILL FALL 20 TO 30 DEGREES OVER THE NEXT 1-2 DAYS
BEHIND THE FRONT IN THE MID-ATLANTIC AND SOUTHEAST DUE TO THE PUSH
OF COLDER AIR FROM THE NORTH ALONG WITH CLOUDS AND RAIN ALONG AND
BEHIND THE BOUNDARY. LOCALLY HEAVY RAIN IS EXPECTED AT TIMES FOR
PORTIONS OF EASTERN AND SOUTHERN TEXAS WHERE A FEW LOCATIONS COULD
PICK UP 2-4 INCHES THROUGH SATURDAY MORNING.
ACROSS THE GREAT LAKES REGION, LIGHT RAIN AND SNOW SHOWERS WILL
LINGER THROUGH FRIDAY NIGHT AS AND UPPER TROUGH AND WEAK COLD
FRONT MOVE THROUGH THE REGION, BUT PRECIPITATION TOTALS ARE
EXPECTED TO REMAIN LOW. A FEW INCHES OF SNOW WILL BE POSSIBLE
ACROSS THE WESTERN UPPER PENINSULA OF MICHIGAN THROUGH FRIDAY
AFTERNOON BUT ANY SNOWFALL ACCUMULATIONS ACROSS REMAINING AREAS
ARE LIKELY TO REMAIN AN INCH OR LESS.
ACROSS THE WESTERN U.S., PORTIONS OF VENTURA AND LOS ANGELES
COUNTIES IN SOUTHERN CALIFORNIA, A CRITICAL RISK OF FIRE WEATHER
CONDITIONS WILL CONTINUE THROUGH THE REMINDER OF THE DAY TODAY,
WITH A DIMINISHING THREAT OVERNIGHT. WIND GUSTS OF 40-50 MPH AND
LOW RELATIVE HUMIDITY WILL HELP SUPPORT THE THREAT, BUT DECREASING
WINDS OVERNIGHT SHOULD ALLOW FOR SIGNIFICANTLY IMPROVED CONDITIONS
BY FRIDAY MORNING.
A PACIFIC COLD FRONT WILL CROSS WASHINGTON AND OREGON TONIGHT,
COINCIDENT WITH A BAND OF LOWER ELEVATION RAIN AND MOUNTAIN SNOW.
LIGHT MOUNTAIN SNOW ACCUMULATIONS ARE EXPECTED FOR THE NORTHERN
ROCKIES AS THE FRONT MOVES THROUGH ON FRIDAY. AFTER A BRIEF LULL,
ANOTHER PACIFIC STORM SYSTEM WILL REACH THE PACIFIC NORTHWEST
FRIDAY NIGHT AND LIKELY BRING SOME HEAVIER PRECIPITATION TO THE
NORTHWEST, FOCUSED ACROSS WESTERN WASHINGTON. SNOWFALL
ACCUMULATIONS OF 1 TO 2 FEET ARE LIKELY IN THE HIGHER ELEVATIONS
OF THE NORTHERN WASHINGTON CASCADES THROUGH SATURDAY EVENING WHILE
THE COASTAL RANGES AND LOWER ELEVATIONS POTENTIALLY PICK UP 1-2
INCHES OF RAIN.
