...FRIGID AIRMASS DESCENDS INTO CENTRAL U.S. THIS WEEKEND
SPREADING INTO THE SOUTHEAST ON MONDAY WHILE THE WEST WARMS UP...
...SNOWY, VERY COLD AND WINDY FROM NORTHERN PLAINS TO GREAT LAKES
THIS WEEKEND...
..CRITICAL FIRE WEATHER IN SOUTHERN TEXAS ON SUNDAY
AN UNUSUALLY STRONG SURGE OF POLAR AIRMASS IS IN STORE FOR MUCH OF
THE EASTERN TWO-THIRDS OF COUNTRY OVER THE NEXT FEW DAYS. THE
LEADING EDGE OF THIS POLAR AIR MASS IS ALREADY PLUNGING SOUTHWARD
THROUGH THE NORTHERN PLAINS THIS SATURDAY AFTERNOON. THIS POLAR
PLUNGE WILL BE IN STARK CONTRAST WITH THE INCREASINGLY MILD
CONDITIONS ACROSS THE WEST AND ACROSS THE EAST THIS WEEKEND. THE
STRONG TEMPERATURE CONTRAST BETWEEN THE CENTRAL AND THE EASTERN
U.S. WILL WORK IN CONCERT WITH A DEEPENING UPPER-LEVEL TROUGH TO
SPAWN AND INTENSIFY A LOW PRESSURE SYSTEM WHICH WILL TRAVERSE THE
ENTIRE EASTERN HALF OF THE COUNTRY OVER THE NEXT COUPLE OF DAYS.
A SWATH OF WET SNOW IS FORECAST TO FOLLOW THE NORTHERN EDGE OF THE
LOW PRESSURE SYSTEM, SPREADING ACROSS THE MIDWEST THIS AFTERNOON,
REACHING INTO LOWER MICHIGAN TONIGHT. THE LOWER GREAT LAKES
SHOULD SEE THE PRECIPITATION STARTING OUT AS RAIN ON SUNDAY BUT AS
COLDER AIR ARRIVES BEHIND THE LOW PRESSURE SYSTEM, PERIODS OF SNOW
WITH FALLING TEMPERATURES ALONG WITH WINDY CONDITIONS ARE EXPECTED
ON MONDAY. AREAS NEAR THE SOUTHERN SHORE OF LAKE MICHIGAN
INCLUDING CHICAGO COULD BE IMPACTED BY A PERIOD OF LOCALLY
ENHANCED SNOWFALL SUNDAY NIGHT WHEN A SMALLER SCALE LOW PRESSURE
SYSTEM COULD FORM OVER THE RELATIVELY WARM LAKE MICHIGAN.
MEANWHILE, THE WESTERN SLOPES OF THE CENTRAL APPALACHIANS CAN
EXPECT TO SEE PERIODS OF SNOW LATER ON MONDAY AS WELL.
ACROSS THE SOUTH AND THE EAST COAST, BROAD SOUTHERLY FLOW AHEAD OF
THE INTENSIFYING LOW PRESSURE SYSTEM WILL BRING VERY MILD
CONDITIONS FOR NOVEMBER OVER THE WEEKEND BEFORE THE ARRIVAL OF
SHARPLY FALLING TEMPERATURES ASSOCIATED WITH THE POLAR SURGE.
HIGH TEMPERATURES OF 70 DEGREES COULD REACH AS FAR NORTH AS THE
NATION'S CAPITAL SUNDAY AFTERNOON TOGETHER WITH PASSING
THUNDERSTORMS ACROSS THE MID-ATLANTIC. A HIGHER CHANCE OF SHOWERS
AND THUNDERSTORMS IS EXPECTED ACROSS SOUTHERN HALF OF NEW ENGLAND
LATER SUNDAY AND SUNDAY NIGHT. A POTENT COLD FRONT WILL SWEEP
THROUGH THE EAST COAST AND THEN OUT INTO THE ATLANTIC SUNDAY NIGHT
WITH PASSING SHOWERS AND EMBEDDED THUNDERSTORMS UP AND DOWN THE
EAST COAST. THIS WILL BE FOLLOWED BY SHARPLY FALLING TEMPERATURES
AND INCREASINGLY BLUSTERY WINDS FROM THE WEST ON MONDAY. HIGH
TEMPERATURES WILL STRUGGLE TO REACH THE FREEZING MARK ON MONDAY
ALONG THE CENTRAL AND CENTRAL APPALACHIANS WHILE BELOW FREEZING
TEMPERATURES ARE FORECAST TO REACH DEEP INTO THE SOUTH BY MONDAY
MORNING. FREEZE WATCHES AND WARNINGS ARE ALREADY POSTED FOR MANY
AREAS ACROSS THE SOUTHERN PLAINS TO THE DEEP SOUTH.
IN THE WEST, AN UPPER RIDGE WILL BE AMPLIFYING AS THE POLAR PLUNGE
OCCURS IN THE CENTRAL AND EASTERN U.S. THE UPPER RIDGE WILL
EXPAND THE UNSEASONABLY WARM TEMPERATURES INTO THE NORTHERN HIGH
PLAINS BY MONDAY. MEANWHILE, INCREASING WINDS AND DRY CONDITIONS
ARE FORECAST TO SUPPORT CRITICAL FIRE WEATHER CONDITIONS FOR
PORTIONS OF SOUTHERN TEXAS ON SUNDAY, ACCORDING TO THE STORM
PREDICTION CENTER. ACROSS THE PACIFIC NORTHWEST, RAIN ASSOCIATED
WITH THE NEXT SYSTEM FROM THE PACIFIC IS FORECAST TO ARRIVE ON
MONDAY.
