...RECORD COLD SUBFREEZING TEMPERATURES THIS MORNING ACROSS MUCH
OF THE SOUTH BEFORE A GRADUAL WARM UP BY THIS WEEKEND...
...WET WEATHER PATTERN IN PLACE ACROSS THE PACIFIC NORTHWEST AS
SEVERAL ROUNDS OF MODERATE TO LOCALLY HEAVY RAIN IMPACT THE
REGION...
A LARGE AREA OF HIGH PRESSURE STRETCHING FROM THE NORTHEAST TO THE
SOUTHERN PLAINS WILL ALLOW FOR A FRIGID MORNING ACROSS MUCH OF THE
CENTRAL AND EASTERN UNITED STATES. IN FACT, RECORD COLD IS
POSSIBLE FOR SEVERAL LOCATIONS FROM LOUISIANA TO MAINE IN THE FORM
OF DAILY RECORD LOW TEMPERATURES. READINGS INTO 20S AND 30S ARE
LIKELY TO BE WIDESPREAD, WITH LOCALIZED TEENS POSSIBLE IN THE
TYPICAL COLD VALLEY LOCATIONS JUST BEFORE SUNRISE. THE MAIN
IMPACTS ASSOCIATED WITH THESE TEMPERATURES WILL BE THE FIRST
FREEZE OF THE SEASON FOR MANY LOCATIONS. SENSITIVE PLANTS COULD BE
DAMAGED OR KILLED AND EXPOSED PIPES COULD BURST IF PROPER
PRECAUTIONS ARE NOT TAKEN. FREEZE WARNINGS EXTEND FROM EASTERN
TEXAS TO SOUTHERN PENNSYLVANIA AND NEW JERSEY. FORTUNATELY, FOR
THOSE WHO DISLIKE THE COLD, CONDITIONS SHOULD GRADUALLY WARM WITH
TEMPERATURES REACHING CLOSER TO AVERAGE FOR THIS TIME OF YEAR BY
SATURDAY.
ON THE OPPOSITE SIDE OF THE COUNTRY, UNSETTLED WEATHER IS SET TO
REMAIN ACROSS THE PACIFIC NORTHWEST AS A FEW ATMOSPHERIC RIVERS
MOVE INLAND OVER THE REGION. THE FIRST BATCH OF PRECIPITATION IS
ONGOING THIS MORNING AND WILL SPREAD MOISTURE INTO THE NORTHERN
ROCKIES THROUGH TONIGHT. SNOW LEVELS WILL BE RATHER HIGH, WITH
MOST SNOWFALL ACCUMULATIONS LOCATED ACROSS THE YELLOWSTONE REGION,
NORTHWEST MONTANA, AND THE HIGHEST TERRAIN OF THE NORTHERN
CASCADES. LOCALIZED SMALL STREAM AND URBAN FLOODING IS POSSIBLE
ACROSS THE CASCADES AND COASTAL RANGES. BY FRIDAY NIGHT THE NEXT
ROUND OF MODERATE TO LOCALLY HEAVY RAIN IS EXPECTED TO PUSH INLAND
AND CREATE ADDITIONAL CHANCES FOR LOCALIZED FLOODING. RECENT BURN
SCARS WILL BE MOST SUSCEPTIBLE TO FLASH FLOODING NEAR NORTHWEST
CALIFORNIA AND SOUTHWEST OREGON.
MOSTLY DRY AND TRANQUIL CONDITIONS ARE FORECAST THROUGH SATURDAY
ACROSS THE REMAINDER OF THE CONUS. WARMING TEMPERATURES WILL LEAD
TO WIDESPREAD HIGHS INTO THE 60S AND 70S BY SATURDAY FROM THE
SOUTHWEST AND CENTRAL/SOUTHERN PLAINS TO THE MID-ATLANTIC, MAKING
FOR A PICTURE-PERFECT FIRST WEEKEND OF NOVEMBER. MEANWHILE, STRONG
NORTHEASTERLY WINDS BEHIND A COLD FRONT WILL MAKE FOR BLUSTERY
CONDITIONS AND ROUGH SURF ACROSS MUCH OF THE FLORIDA COASTLINE
