...SIGNIFICANT WINTER STORM LIKELY ACROSS PARTS OF THE NORTHERN
PLAINS AND UPPER MIDWEST; SEVERE WEATHER AND CRITICAL FIRE RISK
OVER CENTRAL/SOUTHERN PLAINS ON SUNDAY...
...EXCESSIVE RAINFALL CONCERNS ALONG DC TO BOSTON URBAN CORRIDOR

A NUMBER OF LOW PRESSURE SYSTEMS WILL PRODUCE UNSETTLED WEATHER
ACROSS THE EAST AND WEST COASTS TODAY. IN THE EAST, A NORTHERN
STREAM SYSTEM WILL BRING HEAVY SNOW TO INTERIOR NORTHEAST/NORTHERN
NEW ENGLAND TODAY. WINTER STORM WARNINGS ARE IN EFFECT FROM
NORTHEASTERN NEW YORK THROUGH VERMONT, NEW HAMPSHIRE AND MAINE
WHERE A SWATH OF HEAVY SNOW WILL LIKELY DUMP BETWEEN 6-12 INCHES
WITH ISOLATED HIGHER AMOUNTS THROUGH TONIGHT. TO THE SOUTH,
SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO IMPACT THE
REST COASTAL NORTHEAST DOWN TO THE SOUTHERN TIP OF FLORIDA TODAY.
A PARTICULARLY HEAVY AXIS OF RAINFALL IS FORECAST TO SETUP ALONG
THE I-95 CORRIDOR FROM WASHINGTON DC TO BOSTON TODAY WHERE A
SLIGHT RISK OF EXCESSIVE RAINFALL LEADING TO FLASH FLOODING IS IN
EFFECT (LEVEL 2/4). CONDITIONS IMPROVE ACROSS THE EAST COAST ON
SUNDAY.
OUT WEST, A POTENT UPPER-LEVEL LOW WILL PROMOTE COASTAL SCATTERED
TO ISOLATED THUNDERSTORMS AND LOW ELEVATION RAIN SHOWERS, WHILE
HEAVY SNOW BLANKETS THE SIERRA AND SHASTA SISKIYOUS TODAY. SNOW
SHOWERS SPREAD INTO THE ROCKIES THIS AFTERNOON. SNOWFALL TOTALS OF
6-12 INCHES ARE EXPECTED FOR THE AFOREMENTIONED AREAS BY THE END
OF THE WEEKEND. THE UPPER TROUGH ASSOCIATED WITH THE UNSETTLED
WEATHER IN THE WEST WILL BE RESPONSIBLE FOR THE DEVELOPMENT OF A
MAJOR WINTER STORM OVER THE NORTHERN PLAINS AND UPPER MIDWEST
BEGINNING TODAY.
AN EXTENSIVE AND HIGH IMPACT STORM SYSTEM WILL PRODUCE WIDESPREAD
HEAVY SNOW AND GUSTY WINDS OVER THE NORTHERN PLAINS AND UPPER
MIDWEST THROUGH EARLY NEXT WEEK. HEAVY SNOW WILL LIKELY SPREAD
ACROSS MUCH OF CENTRAL AND EASTERN MONTANA TONIGHT, THEN EXPAND
INTO THE NORTHERN PLAINS AND UPPER MIDWEST ON SUNDAY AND CONTINUE
INTO MONDAY. THERE IS A HIGH CHANCE (>70%) OF AT LEAST EIGHT
INCHES OF SNOW EXTENDING FROM PORTIONS OF THE DAKOTAS AND
NORTH-CENTRAL NEBRASKA NORTHEASTWARD THROUGH MINNESOTA AND INTO
NORTHERN WISCONSIN. HEAVY SNOW AND GUSTY WINDS WILL PRODUCE AREAS
OF BLOWING AND DRIFTING SNOW AND POSSIBLE BLIZZARD CONDITIONS
SUNDAY INTO MONDAY. HAZARDOUS TRAVEL AND ROAD CLOSURES ARE
EXPECTED LATE SATURDAY INTO EARLY NEXT WEEK. STRONG WINDS AND
HEAVY, WET SNOW ON TREES AND POWER LINES MAY RESULT IN TREE DAMAGE
AND POWER OUTAGES. BLUSTERY WIND GUSTS IN EXCESS OF 50 MPH ON
SUNDAY MAY RESULT IN POWER OUTAGES, BLOWING DUST THAT RESULTS IN
REDUCED VISIBILITY AND DAMAGE TO PROPERTY.
THERE ARE SEVERE AND FIRE WEATHER CONCERNS WITHIN THE WARM SECTOR
OF THIS DYNAMIC SYSTEM. THERE'S A SLIGHT RISK OF SEVERE
THUNDERSTORMS (LEVEL 2/5) ACROSS PARTS OF KANSAS AND OKLAHOMA ON
SATURDAY, WHERE LARGE HAIL AND A FEW TORNADOES WILL BE THE MAIN
THREATS. STRONG SOUTHWESTERLY FLOW BEGINNING TODAY WILL SUPPORT AN
ELEVATED FIRE WEATHER THREAT OVER FAR WESTERN TEXAS. RAPID
CYCLOGENESIS AND STRENGTHENING OF THE PLAINS WINTER STORM WILL
LEAD TO INCREASED DRY SOUTHWESTERLY FLOW INTO THE CENTRAL/SOUTHERN
HIGH PLAINS BEHIND A WELL-DEFINED DRY LINE ON SATURDAY. THESE
CONDITIONS WILL SUPPORT A CRITICAL FIRE WEATHER THREAT ON SATURDAY.
