...A PACIFIC STORM SYSTEM PUSHING INTO THE WEST COAST WILL BRING
LOCALLY HEAVY RAIN NEAR THE COAST, AND HEAVY HIGH ELEVATION
SNOWFALL INTO THE INTERMOUNTAIN WEST OVER THE NEXT COUPLE OF
DAYS...
...QUICK-HITTING WAVE OF LOW PRESSURE WILL BRING A ROUND OF
ACCUMULATING SNOWFALL ACROSS THE UPPER MIDWEST TONIGHT, AND HEAVY
SNOW ACROSS THE GREAT LAKES THURSDAY, AND INTO NEW ENGLAND
THURSDAY NIGHT AND FRIDAY MORNING...
...NEXT ROUND OF SNOW EXPECTED TO QUICKLY SPREAD ACROSS THE
CENTRAL PLAINS TO THE OHIO VALLEY ON FRIDAY WITH SHOWERS AND SOME
THUNDERSTORMS ACROSS THE MID-SOUTH...
MODERATE TO LOCALLY HEAVY PRECIPITATION ASSOCIATED WITH A PACIFIC
LOW PRESSURE SYSTEM IS CURRENTLY OVERSPREADING
NORTHERN CALIFORNIA AND INTO OREGON. THE MOISTURE WILL THEN
PENETRATE INTO MUCH OF THE NORTHWESTERN U.S. AND BEGIN TO INTERACT
WITH COLDER AIR SLOWLY FILTERING ACROSS THE NORTHERN ROCKIES.
THIS INTERACTION WILL EXPAND THE COVERAGE OF SNOW EASTWARD ACROSS
MUCH OF THE INTERMOUNTAIN WEST THROUGH THE NEXT COUPLE OF DAYS.
THE HIGHER TERRAIN OF THE CASCADES, SIERRA NEVADA, AND THE
NORTHERN ROCKIES WILL RECEIVE THE HIGHEST SNOWFALL AMOUNTS OF AS
MUCH AS 2 FEET WITH ISOLATED HEAVIER AMOUNTS GOING THROUGH
THURSDAY. BY FRIDAY, A REINFORCING PUSH OF POLAR AIR FROM CANADA
WILL BRING COLDER AND DRIER AIR INTO THE NORTHERN PLAINS AND
NORTHERN ROCKIES. MEANWHILE, THE SNOW WILL BE PUSHED FARTHER
SOUTH TOWARD AND INTO THE CENTRAL ROCKIES NEAR AND BEHIND THE
POLAR FRONT. A PIECE OF UPPER-LEVEL ENERGY EJECTING OUT OF THE
ROCKIES WILL HELP DEVELOP A NEW LOW PRESSURE SYSTEM OVER THE
CENTRAL HIGH PLAINS AND QUICKLY HEAD EAST ACROSS THE CENTRAL
PLAINS THURSDAY NIGHT INTO FRIDAY MORNING. THIS NEW SYSTEM WILL
BRING THE NEXT ROUND OF SNOW ACROSS THE CENTRAL PLAINS TO THE OHIO
VALLEY ON FRIDAY WITH SHOWERS AND SOME THUNDERSTORMS DEVELOPING
ACROSS THE MID-SOUTH BY FRIDAY AFTERNOON.
MEANWHILE, A DEVELOPING WAVE OF LOW PRESSURE ALONG A FRONT IS
EXPECTED TO SPREAD A QUICK ROUND OF ACCUMULATING SNOWFALL ACROSS
THE UPPER MIDWEST THROUGH TONIGHT, ACROSS THE GREAT LAKES ON
THURSDAY, AND INTO NEW ENGLAND THURSDAY NIGHT AND FRIDAY MORNING.
A FEW INCHES OF SNOW CAN BE EXPECTED TO ACCOMPANY THIS SYSTEM OVER
THE UPPER MIDWEST TONIGHT. AS THE SYSTEM INTENSIFIES ON THURSDAY,
6 TO 12 INCHES CAN BE EXPECTED ACROSS THE CENTRAL GREAT LAKES WITH
LOCALLY HIGHER AMOUNTS POSSIBLE. 6 TO 12 INCHES OF SNOW CAN ALSO
BE EXPECTED ACROSS UPSTATE NEW YORK INTO NORTHERN NEW ENGLAND
DOWNSTREAM FROM LAKE ONTARIO DUE TO MOISTURE AND INSTABILITY
ENHANCEMENT AS THE LOW PRESSURE CENTER QUICKLY MOVES ACROSS THE
REGION THURSDAY NIGHT AND THEN EXITS NEW ENGLAND FRIDAY MORNING.
TEMPERATURES ALONG THE EASTERN SEABOARD WILL BE GENERALLY BELOW
NORMAL INTO THURSDAY MORNING. MILDER AIR OVER THE MID-SECTION OF
THE COUNTRY TODAY WILL SPREAD EAST INTO MUCH OF THE EASTERN U.S.
ON THURSDAY. HOWEVER, AN REINFORCING PUSH OF ARCTIC AIR FROM
CANADA WILL BRING BELOW NORMAL TEMPERATURES THROUGH THE NORTHERN
TIER STATES ON FRIDAY WITH MUCH BELOW NORMAL TEMPERATURES
SPREADING INTO THE NORTHERN HIGH PLAINS. MUCH OF THE SOUTHWEST
WILL AVERAGE NEAR OR SLIGHTLY ABOVE NORMAL THROUGH FRIDAY.
