VALID 00Z SAT APR 12 2025 - 00Z MON APR 14 2025
...STORMY WEATHER FROM THE MID-ATLANTIC TO THE NORTHEAST WITH LATE
SEASON ACCUMULATING SNOW IN THE HIGHER ELEVATIONS...
...ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS FORECAST FOR THE
SOUTHERN PLAINS SATURDAY AND SUNDAY...
...RECORD WARMTH EXPECTED THROUGH THE WEEKEND FOR PORTIONS OF THE
INTERMOUNTAIN WEST, SOUTHWEST, AND SOUTHERN PLAINS...
A SLOW-MOVING COASTAL LOW WILL CREATE STORMY WEATHER CONDITIONS
WITH WIDESPREAD PRECIPITATION CHANCES AND GUSTY WINDS FROM THE
MID-ATLANTIC TO THE NORTHEAST THIS WEEKEND. HEAVY RAIN ACROSS THE
MID-ATLANTIC TODAY COULD RESULT IN ISOLATED INSTANCES OF FLASH
FLOODING, ESPECIALLY IN URBAN AND POOR DRAINAGE AREAS. AS
PRECIPITATION EXPANDS INTO THE NORTHEAST ON SATURDAY, COOLER
TEMPERATURES WILL ALLOW FOR A TRANSITION TO WINTRY PRECIPITATION
TYPES. HIGHER ELEVATIONS IN THE NORTHEAST CAN EXPECT PRECIPITATION
TO FALL MAINLY AS SNOW WITH ACCUMULATIONS OF UP TO A FEW INCHES
POSSIBLE. ELSEWHERE IN THE NORTHEAST, A MIX OF WINTRY
PRECIPITATION AND RAIN IS EXPECTED. PRECIPITATION WILL TAPER OFF
ON SUNDAY AS THE LOW MOVES TOWARDS THE CANADIAN MARITIMES, BUT
GUSTY CONDITIONS MAY LINGER ALONG THE COAST.
IN THE WEST, A FRONTAL SYSTEM IS EXPECTED TO PUSH SOUTH AND EAST
ACROSS THE REGION THIS WEEKEND, BRINGING PRECIPITATION CHANCES
FROM THE NORTHWEST ACROSS THE NORTHERN AND CENTRAL ROCKIES TO THE
NORTHERN PLAINS AND UPPER MIDWEST. PRECIPITATION WILL FALL AS RAIN
AT LOWER ELEVATIONS AND WINTRY MIXED PRECIPITATION AND SNOW AT
HIGHER ELEVATIONS. WINTRY PRECIPITATION WILL ALSO BE POSSIBLE
SATURDAY NIGHT ACROSS THE NORTHERN AND CENTRAL HIGH PLAINS ON THE
BACKSIDE OF THE SYSTEM. THE CENTRAL LOW ASSOCIATED WITH THIS
SYSTEM WILL STRENGTHEN OVER THE NORTHERN ROCKIES/PLAINS ON
SATURDAY THEN TRACK TOWARD THE UPPER MIDWEST ON SUNDAY.
THUNDERSTORMS WILL BE POSSIBLE IN THE VICINITY OF THE LOW, AND
ISOLATED SEVERE THUNDERSTORMS WITH DAMAGING WIND GUSTS WILL BE
POSSIBLE SATURDAY AFTERNOON.
TO THE SOUTH OF THE WESTERN FRONTAL SYSTEM, DRY DOWNSLOPE FLOW OFF
OF THE ROCKY MOUNTAINS IS EXPECTED TO CREATE ELEVATED TO CRITICAL
FIRE WEATHER CONDITIONS ACROSS THE SOUTHERN PLAINS SATURDAY AND
SUNDAY. VERY LOW RELATIVE HUMIDITIES COMBINED WITH GUSTY WINDS
WILL CREATE FAVORABLE CONDITIONS FOR RAPID FIRE SPREAD.
TEMPERATURE WISE, AN EASTWARD MOVING UPPER RIDGE WILL RESULT IN
WELL ABOVE NORMAL TEMPERATURES ACROSS THE WESTERN AND CENTRAL U.S.
THIS WEEKEND. THE CURRENT FORECAST CALLS FOR RECORD WARM HIGH
TEMPERATURES FOR PORTIONS OF THE INTERMOUNTAIN WEST, SOUTHWEST,
AND SOUTHERN PLAINS WITH HIGHS IN THE 80S AND 90S. SOME LOCATIONS
IN THE SOUTHWEST MAY SEE TEMPERATURES REACH OVER 100 DEGREES.
BELOW AVERAGE TEMPERATURES ARE EXPECTED THROUGH THE WEEKEND FOR
THE EASTERN U.S., AND BELOW AVERAGE TEMPERATURES WILL ALSO DEVELOP
ALONG THE NORTHERN TIER OF THE WESTERN AND CENTRAL U.S. WITH
EXPECTED PRECIPITATION.
RIVER FLOODING IS STILL ONGOING IN THE OHIO AND MISSISSIPPI
VALLEYS FROM THE MULTI-DAY HEAVY RAINFALL EVENT LAST WEEK, AND
FLOOD WARNINGS AND ADVISORIES REMAIN IN EFFECT.
