VALID 12Z THU APR 10 2025 - 12Z SAT APR 12 2025
...ELEVATED RISK OF SEVERE WEATHER FROM PORTIONS OF THE LOWER OHIO
VALLEY AND THE MID/DEEP SOUTH THURSDAY INTO PARTS OF THE SOUTHERN
EASTERN SEABOARD FRIDAY...
...MIXED RAIN/WET SNOW FROM THE GREAT LAKES TO INTERIOR NEW
ENGLAND THURSDAY WILL BE FOLLOWED BY COLD SOAKING RAIN SHOWERS
ACROSS THE MID-ATLANTIC FRIDAY INTO EARLY SATURDAY...
...WELL ABOVE NORMAL AND NEAR-RECORD WARMTH BUILDS ACROSS THE WEST
AND INTO THE PLAINS THROUGH THE WEEKEND...
..TURNING COOLER AND UNSETTLED ACROSS THE PACIFIC NORTHWEST
THE MAIN WEATHER STORY ACROSS THE UNITED STATES WILL BE A LOW
PRESSURE SYSTEM THAT IS FORECAST TO PROGRESSIVELY DEVELOP OVER THE
EASTERN U.S. THE NEXT COUPLE OF DAYS. THIS SYSTEM WILL GRADUALLY
STRENGTHEN AND BRING EVERYTHING FROM SEVERE WEATHER, TO WIDESPREAD
COLD SOAKING RAIN SHOWERS, TO EVEN A LITTLE BIT OF SNOW THROUGH
THE EARLY PART OF THE WEEKEND. KICKING THINGS OFF WILL BE SOME
AREAS OF MIXED RAIN AND WET SNOW SHOWERS FROM THE GREAT LAKES TO
INTERIOR NEW ENGLAND THROUGH FRIDAY MORNING AS THE FIRST WAVE OF
MOISTURE ASSOCIATED WITH THE DEVELOPING LOW MOVES IN. THE LOW WILL
THEN CONTINUE TO STRENGTHEN AS IT MOVES SOUTHEASTWARD INTO THE
LOWER OHIO VALLEY AND MID-SOUTH THURSDAY AFTERNOON AND EVENING.
AHEAD OF THE LOW AND ITS ATTENDANT COLD FRONT, INCREASING MOISTURE
AND INSTABILITY WILL SET THE STAGE FOR STRONG TO SEVERE
THUNDERSTORMS ACROSS THE REGION LATE THURSDAY INTO EARLY FRIDAY.
AS A RESULT, THE STORM PREDICTION CENTER MAINTAINS A SLIGHT RISK
(LEVEL 2/5) OF SEVERE THUNDERSTORMS, WITH DAMAGING WINDS AND LARGE
HAIL THE MAIN HAZARDS. INTENSIFICATION OF THE LOW PRESSURE SYSTEM
CONTINUES ON FRIDAY AS IT BEGINS TO TRACK NORTHEASTWARD INTO THE
MID-ATLANTIC. WITH COLD HIGH PRESSURE ANCHORED ACROSS SOUTHEAST
CANADA, PLENTIFUL MOISTURE AND BRISK EAST AND NORTHEASTERLY WINDS
WILL COMBINE TO PRODUCE A COLD SOAKING RAIN AND A SOGGY, BLUSTERY,
AND RAW END TO THE WORK WEEK ACROSS MUCH OF THE NORTHERN
MID-ATLANTIC. IN THE WARM SECTOR FARTHER SOUTH, STRONG
THUNDERSTORMS WILL AGAIN BE A CONCERN FROM PARTS OF SOUTHEAST
VIRGINIA TO NORTHERN FLORIDA. RAIN SHOWERS WILL LIKELY CONTINUE
INTO SATURDAY ACROSS PARTS OF THE MID-ATLANTIC AND NORTHEAST, WITH
A LITTLE MORE SNOW POSSIBLE ON THE NORTHERN FRINGE OF THE
PRECIPITATION SHIELD IN NORTHERN NEW ENGLAND. CONDITIONS GRADUALLY
IMPROVE ACROSS THE EAST LATER SATURDAY INTO SUNDAY WITH THE STORM
SLOWLY PIVOTING OUT INTO THE ATLANTIC.
IN STARK CONTRAST TO THE COOL, WET, AND STORMY WEATHER EXPECTED IN
THE EAST THE NEXT FEW DAYS, VERY WARM AND DRY WEATHER WILL PREVAIL
ACROSS MOST OF THE WEST THROUGH THE WEEKEND THANKS TO A BUILDING
UPPER-LEVEL RIDGE OF HIGH PRESSURE. THE STRENGTHENING RIDGE WILL
PROMOTE PLENTY OF SUNSHINE AND INCREASING WARMTH FOR MOST OF THE
REGION THROUGH SATURDAY, WITH DAILY HIGH TEMPERATURES SOARING TO
BETWEEN 10 AND 30 DEGREES ABOVE NORMAL. THESE ANOMALIES TRANSLATE
TO HIGHS IN THE 70S, 80S, AND 90S ACROSS THE LOWER ELEVATIONS OF
THE SOUTHWEST, GREAT BASIN, INTERMOUNTAIN WEST AND
NORTHERN/CENTRAL PLAINS, AND HIGHS IN THE 90S AND 100S ACROSS
PORTIONS OF THE DESERT SOUTHWEST AND SOUTHERN PLAINS. HIGH
TEMPERATURES MAY EVEN APPROACH OR POSSIBLY BREAK RECORDS FOR MANY
PLACES THURSDAY, FRIDAY AND INTO THE WEEKEND.
UNLIKE THE REST OF THE WEST, THE PACIFIC NORTHWEST WILL TURN
COOLER AND UNSETTLED AGAIN THROUGH THE WEEKEND AS A SERIES OF
FRONTAL SYSTEMS PUSH INLAND. THE FRONTS THAT MOVE THROUGH WILL BE
ACCOMPANIED BY PACIFIC MOISTURE, LEADING TO EPISODES OF SHOWERS
OVER THE COURSE OF THE NEXT FEW DAYS. SHOWERS WILL BE COMPRISED OF
RAIN IN THE COASTAL REGIONS AND LOWER ELEVATIONS, WHILE SNOW WILL
FLY IN PARTS OF THE HIGH COUNTRY. SNOW ACCUMULATIONS IN THE
MOUNTAINS WILL MOSTLY BE LIGHT, WITH ANY HIGHER AMOUNTS CONFINED
TO THE HIGHEST PEAKS OF THE CASCADES. THE INCREASING CLOUDS AND
PRECIPITATION ASSOCIATED WITH THE COOL PACIFIC AIR BROUGHT IN BY
THESE SYSTEMS WILL LEAD TO HIGH TEMPERATURES TURNING PROGRESSIVELY
BELOW NORMAL THROUGH THE EARLY PART OF THE WEEKEND.
