VALID 12Z THU JAN 23 2025 - 12Z SAT JAN 25 2025
...VERY COLD WINTER TEMPERATURES CONTINUE FROM THE ROCKIES TO THE
EAST COAST WITH A SLOW WARM UP ANTICIPATED HEADING INTO THE
WEEKEND....
...PERIODS OF LAKE-EFFECT SNOW EXPECTED DOWNWIND OF THE GREAT
LAKES WITH SOME MODERATE ACCUMULATIONS POSSIBLE...
...THERE IS A CRITICAL RISK OF FIRE WEATHER OVER PARTS OF SOUTHERN
CALIFORNIA THURSDAY...
WELL BELOW AVERAGE, VERY COLD TEMPERATURES WILL CONTINUE FOR MOST
OF THE COUNTRY FROM THE ROCKIES EAST TO THE EAST COAST THE NEXT
COUPLE OF DAYS, WITH SOME OF THE MOST NOTABLE DEPARTURES FROM
AVERAGE OVER THE SOUTHEAST. FORECAST HIGHS THURSDAY GENERALLY
RANGE FROM THE TEENS AND 20S FOR THE NORTHERN PLAINS AND MIDWEST,
THE 20S AND 30S FROM THE ROCKIES AND CENTRAL PLAINS EAST THROUGH
THE OHIO VALLEY TO THE NORTHEAST, AND THE 30S AND 40S FROM THE
SOUTHERN PLAINS EAST TO THE SOUTHEAST. ALTHOUGH WINDS HAVE COME
DOWN COMPARED TO RECENT DAYS, WIND CHILLS WILL STILL BE QUITE
FRIGID AND MAKE TEMPERATURES FEEL AROUND 10 DEGREES COLDER. SOME
OF THE MORE ADVERSE IMPACTS FROM THESE TEMPERATURES WILL BE FOR
PORTIONS OF THE GULF COAST AND SOUTHEAST WHERE SNOW AND ICE LINGER
ON ROADS AND KEEP TRAVEL HAZARDOUS AFTER THE HISTORIC WINTER
STORM. IT MAY TAKE A FEW MORE DAYS FOR THESE ROAD CONDITIONS TO
IMPROVE. MORNING LOWS ARE ALSO EXPECTED TO DROP BELOW FREEZING
AGAIN FRIDAY AND SATURDAY ALONG THE GULF COAST AND INTO NORTHERN
FLORIDA, KEEPING SENSITIVE VEGETATION AT RISK. CONDITIONS WILL
MODERATE SOME ON FRIDAY, ESPECIALLY FOR PORTIONS OF THE PLAINS
WHERE WARM WESTERLY WINDS WILL BRING TEMPERATURES UP BY 10-20
DEGREES AND TO AVERAGE TO ABOVE AVERAGE LEVELS. MOST AREAS WILL
CONTINUE TO SLOWLY MODERATE INTO THE WEEKEND.
A CLIPPER SYSTEM PASSING THROUGH THE GREAT LAKES AND INTO THE
INTERIOR NORTHEAST/APPALACHIANS WILL BRING SOME SNOW SHOWERS
THURSDAY. SOME MODERATE ACCUMULATIONS ARE POSSIBLE WITH
LAKE-EFFECT SNOW BANDS FOR FAVORABLE DOWNWIND LOCATIONS OF THE
GREAT LAKES. ANOTHER CLIPPER SYSTEM FOLLOWING QUICKLY IN ITS WAKE
WILL BRING ANOTHER ROUND OF LIGHT SNOW SHOWERS TO THE NORTHERN
PLAINS/UPPER MIDWEST ON FRIDAY AND THE GREAT LAKES AGAIN BY FRIDAY
EVENING. TO THE WEST, PASSAGE OF AN UPPER-LEVEL WAVE/SURFACE COLD
FRONT WILL BRING SOME LIGHT TO MODERATE SNOW SHOWERS TO THE
NORTHERN ROCKIES THURSDAY AND INTO THE CENTRAL ROCKIES/EASTERN
GREAT BASIN FRIDAY.
VERY GUSTY OFFSHORE SANTA ANA WINDS WILL CONTINUE INTO THE DAY
THURSDAY FOR SOUTHERN CALIFORNIA, WITH GUSTS AS HIGH AS 70 MPH FOR
SOME OF THE AREA MOUNTAIN RANGES. THESE WINDS IN COMBINATION WITH
VERY LOW HUMIDITY AND DRY ANTECEDENT CONDITIONS HAVE PROMPTED THE
STORM PREDICTION CENTER TO CONTINUE A CRITICAL RISK OF FIRE
WEATHER (LEVEL 2/3). WIND GUSTS ARE EXPECTED TO COME DOWN IN
STRENGTH HEADING INTO FRIDAY, REDUCING THE FIRE RISK, THOUGH AN
ELEVATED THREAT WILL STILL EXIST GIVEN DRY HUMIDITY AND
CONDITIONS. ELSEWHERE IN THE WEST, CONDITIONS WILL BE MOSTLY DRY
WITH GENERALLY AT OR ABOVE AVERAGE TEMPERATURES. FORECAST HIGHS
THE NEXT COUPLE OF DAYS RANGE FROM THE 30S AND 40S IN THE INTERIOR
WEST AND PACIFIC NORTHWEST AND THE 60S AND 70S FOR CALIFORNIA AND
THE DESERT SOUTHWEST.
