...HEAVY MOUNTAIN SNOW ALONG THE CASCADES WILL SPREAD SOUTHEAST
INTO THE SIERRA NEVADA AND FARTHER INLAND ACROSS IDAHO INTO THE
NORTHERN ROCKIES THROUGH MONDAY...
...THERE IS A SLIGHT TO ENHANCED RISK OF SEVERE THUNDERSTORMS
THROUGH THIS EVENING FROM THE LOWER GREAT LAKES SOUTHWARD, WHILE A
SLIGHT RISK OF SEVERE THUNDERSTORMS EXTENDS FARTHER DOWN THE EAST
COAST THROUGH NORTHERN FLORIDA PENINSULA...
...A WINTER STORM WILL BEGIN TO IMPACT THE NORTHERN AND CENTRAL
ROCKIES FOLLOWED BY THE HIGH PLAINS ON TUESDAY WITH INCREASING
RISK OF WILDFIRES ACROSS THE CENTRAL AND SOUTHERN HIGH PLAINS...
AN INTENSIFYING LOW PRESSURE SYSTEM WHICH IS TRACKING QUICKLY
NORTHEASTWARD ACROSS THE LOWER GREAT LAKES INTO CANADA WILL PUSH A
SHARP COLD FRONT ACROSS THE ENTIRE EAST COAST REGION THROUGH
TONIGHT. THE INCREASINGLY WARM AND UNSTABLE SOUTHERLY FLOW AHEAD
OF THE FRONT WILL BE LIFTED BY THE STRONG DYNAMICS AHEAD OF AN
UPPER-LEVEL TROUGH EDGING IN FROM THE WEST. THESE INTERACTIONS
WILL TRIGGER LINES OF SHOWERS AND THUNDERSTORMS, SOME OF WHICH ARE
EXPECTED TO REACH SEVERE LEVELS. THE STORM PREDICTION CENTER HAS
ISSUED AN ENHANCED RISK OF SEVERE THUNDERSTORMS THROUGH THIS
EVENING FROM THE LOWER GREAT LAKES SOUTHWARD TOWARD THE CENTRAL
APPALACHIANS. AREAS CLOSER TO THE COAST SHOULD SEE A BETTER
CHANCE FOR THE THUNDERSTORMS TO PASS THROUGH LATER TONIGHT INTO
THE EARLY HOURS ON MONDAY. THESE THUNDERSTORMS COULD BE
ACCOMPANIED WITH FREQUENT LIGHTNING, SEVERE THUNDERSTORM WIND
GUSTS, HAIL, AND A FEW TORNADOES. ON MONDAY, THE COLD FRONT WILL
BE HEADING EAST INTO THE ATLANTIC BUT WILL BEGIN TO SLOW DOWN.
SOUTHEASTERN NEW ENGLAND COULD STILL SEE THUNDERSTORMS PASSING
THROUGH MONDAY MORNING AS THE FRONT WILL BE SLOWING DOWN FURTHER.
BY MONDAY NIGHT INTO TUESDAY, ALL OF THE EAST COAST SHOULD HAVE
CLEARED OUT AS A HIGH PRESSURE RIDGE BUILDS IN FROM THE WEST.
MEANWHILE, ACTIVE WEATHER FROM THE PACIFIC CONTINUES TO MOVE INTO
OREGON AND NORTHERN CALIFORNIA AHEAD OF A LANDFALLING CYCLONE.
THIS SYSTEM IS CURRENTLY BRINGING HEAVY RAIN FOR THE LOWER
ELEVATION WHILE HEAVY MOUNTAIN SNOW IS IMPACTING THE CASCADES.
THE HEAVY SNOW IN THE CASCADES WILL BEGIN TO TAPER OFF LATER
TONIGHT, BUT THE SIERRA NEVADA, NORTHERN INTERMOUNTAIN WEST AND
THE NORTHERN ROCKIES WILL BE THE NEXT TARGETS OF HEAVY SNOW FROM
THIS SYSTEM ON MONDAY. FROM MONDAY NIGHT INTO TUESDAY, A WINTER
STORM WILL BEGIN TO TAKE SHAPE ACROSS THE NORTHERN AND CENTRAL
ROCKIES AND INTO THE NEARBY HIGH PLAINS WHERE A LOW PRESSURE
SYSTEM IS FORECAST TO RAPIDLY DEVELOP AND EXPAND IN SIZE. IN
ADDITION, STRONG AND GUSTY WINDS ALONG WITH MOUNTAIN SNOW WILL
ACCOMPANY THE PASSAGE OF A COLD FRONT ACROSS THE GREAT BASIN LATER
MONDAY INTO EARLY TUESDAY. THE EXTENT OF THE HIGH WINDS WILL
LIKELY EXPAND ON TUESDAY ACROSS THE CENTRAL ROCKIES INTO THE HIGH
PLAINS AS THE LOW PRESSURE SYSTEM INTENSIFIES MORE RAPIDLY OVER
THE CENTRAL PLAINS. THE HIGH WINDS WILL BE ACCOMPANIED WITH VERY
DRY CONDITIONS ACROSS THE CENTRAL TO SOUTHERN HIGH PLAINS, WHICH
WILL RAISE THE CONCERN OF FIRE DANGER IN THESE AREAS BEGINNING ON
MONDAY ALONG WITH A RAPID WARM-UP ACROSS THE PLAINS.
