..HEAVY SNOW WINDS DOWN OVER NEW ENGLAND AND SIERRA NEVADA
...HIGH WINDS LIKELY FOR CENTRAL GREAT BASIN AND FOUR
CORNERS/INTERMOUNTAIN WEST...
...CRITICAL FIRE RISK FOR CENTRAL/SOUTHERN HIGH PLAINS THIS
WEEKEND...
A VERY STRONG AND IMPACTFUL LOW PRESSURE SYSTEM, WHICH HAS ALREADY
BROUGHT HEAVY SNOW TO THE SIERRA NEVADA, WILL SPREAD RAIN AND SNOW
INTO THE INTERIOR WEST OVER THE NEXT COUPLE OF DAYS. TONIGHT,
HEAVY SNOW OVER THE SIERRA NEVADA WILL WEAKEN AS THE FOCUS FOR
SNOW, RAIN AND WIND SHIFT EASTWARD. OVER THE NEXT 24 HOURS,
BETWEEN 6-12 INCHES OF SNOW IS EXPECTED TO ACCUMULATE OVER THE
SIERRA NEVADA; RANGES OF NORTHEASTERN CALIFORNIA, NORTHERN NEVADA,
SAWTOOTH; AND THE BLUE MOUNTAINS. HIGH WINDS WILL ACCOMPANY THIS
SYSTEM, PARTICULARLY OVER PARTS OF THE GREAT BASIN AND
INTERMOUNTAIN WEST, WHERE SUSTAINED WINDS OF 35-45 MPH AND GUSTS
UP TO 60 MPH ARE POSSIBLE. HIGH WIND WARNINGS AND WATCHES ARE IN
EFFECT FOR THOSE AREAS AS A RESULT. SNOW SHOWERS SPREAD INTO THE
NORTHERN/CENTRAL ROCKIES FRIDAY NIGHT INTO SATURDAY, WITH 4-8
INCHES POSSIBLE OVER THOSE AREAS.
THIS SYSTEM WILL REORGANIZE AND QUICKLY INTENSIFY AS IT EMERGES
OVER THE FRONT RANGE THIS WEEKEND. HIGH WINDS, WARM WEATHER AND
LOW DEW POINTS WILL SUPPORT A CRITICAL RISK OF FIRE WEATHER OVER
PARTS OF THE CENTRAL AND SOUTHERN HIGH PLAINS BEGINNING FRIDAY AND
CONTINUING THROUGH AT LEAST SUNDAY. SCATTERED RAIN SHOWERS AND
THUNDERSTORMS WILL DEVELOP OVER THE CENTRAL/SOUTHERN PLAINS ON
SATURDAY NIGHT, WHILE SNOW CONTINUES OVER THE NORTHERN
ROCKIES/HIGH PLAINS.
MEANWHILE, IN THE EAST, A DEEP UPPER-LEVEL TROUGH WILL SLOWLY MOVE
OFF THE NORTHEAST COAST OVER THE COMING DAYS. THE ASSOCIATED LOW
PRESSURE SYSTEM, WHICH HAS ALREADY DUMPED SEVERAL INCHES OF SNOW
OVER PARTS OF THE NORTHEAST AND NEW ENGLAND, WILL LINGER AROUND
DOWNEAST MAINE OVER THE NEXT COUPLE OF DAYS, SPREADING SNOW
SHOWERS ACROSS THE STATE AND SURROUNDING AREAS. TONIGHT, THE
HEAVIEST SNOWFALL WILL COME TO AN END, BUT BETWEEN 4-8 INCHES MAY
STILL ACCUMULATE AS THE PARENT LOW LINGERS NEARBY. SNOW SHOWERS
CONTINUE OVER THE ALLEGHENY MOUNTAINS TONIGHT, PRODUCING AROUND
4-8 INCHES OF SNOW. AN OMEGA BLOCK UPPER-LEVEL PATTERN WILL
SUPPORT BELOW AVERAGE TEMPERATURES ACROSS THE WEST AND EAST AND
ABOVE AVERAGE TEMPS IN THE CENTRAL U.S. OVER THE NEXT COUPLE OF
DAYS.
