...HEAVY SNOW FRIDAY NIGHT INTO SATURDAY FROM THE FOUR CORNERS TO
THE SOUTHERN ROCKIES AND NEARBY HIGH PLAINS...
...CHILLY AIRMASS SPREADS INTO SOUTHERN PLAINS BUT VERY MILD
ACROSS THE NORTHERN TIER AND THE SOUTHEAST...
...CRITICAL FIRE WEATHER ACROSS PARTS OF THE SOUTHERN HIGH PLAINS
INTO SOUTHWESTERN TEXAS...
A DEEP LOW PRESSURES SYSTEM IS TAKING ITS TIME DEPARTING INTO
SOUTHEASTERN CANADA WHILE DELIVERING ADDITIONAL LIGHT TO MODERATE
SNOW ACROSS NORTHERN MAINE INTO EARLY THIS EVENING. EVEN THOUGH
THE DEEP STORM WILL BEGIN TO MOVE AWAY FROM NEW ENGLAND TONIGHT,
ITS EXPANSIVE CIRCULATION WILL CONTINUE TO USHER COLD AIR INTO THE
NORTHEAST UNDER BLUSTERY NORTHWESTERLY WINDS THROUGH MUCH OF THE
WEEKEND. SOME LIGHT SNOW COULD REACH THE HIGHER-ELEVATIONS OF NEW
ENGLAND SUCH AS THE GREEN AND WHITE MOUNTAINS THIS WEEKEND.
PERIODS OF LAKE-EFFECT SNOW CAN ALSO BE EXPECTED DOWNWIND OF THE
LOWER GREAT LAKES AND ADIRONDACKS ESPECIALLY DURING THE PASSAGE OF
A REINFORCING COLD FRONT TONIGHT.
MEANWHILE, A CLIPPER LOW PRESSURE SYSTEM WILL MOVE SWIFTLY ACROSS
THE OHIO VALLEY THROUGH TONIGHT BEFORE DISSIPATING AS IT ATTEMPTS
TO CROSS OVER THE APPALACHIANS INTO THE MID-ATLANTIC SATURDAY
MORNING. A SWATH OF MIXED RAIN AND SNOW IS FORECAST FROM THE
MIDWEST TO OHIO VALLEY THROUGH TONIGHT, LINGERING A BIT LONGER
INTO SATURDAY AFTERNOON ALONG THE WESTERN SLOPE OF THE CENTRAL
APPALACHIANS.
STILL A THIRD LOW PRESSURE SYSTEM IS FORECAST TO DEVELOP OVER
TEXAS TONIGHT AND THEN TRACK EASTWARD NEAR OR JUST INLAND FROM THE
GULF COAST THROUGH THE WEEKEND. THE SYSTEM WILL BRING HEAVY SNOW
ACROSS THE HIGHER-ELEVATIONS OF ARIZONA TONIGHT, ACROSS THE
SOUTHERN ROCKIES INTO THE NEARBY HIGH PLAINS ON SATURDAY. IN
ADDITION, THIS SYSTEM WILL BRING A PERIOD OF RAIN, HEAVY AT TIMES,
ALONG WITH EMBEDDED THUNDERSTORMS FROM WEST TO EAST FROM EASTERN
TEXAS THROUGH THE GULF COAST STATES THROUGH THIS WEEKEND, WITH
LOCALIZED FLOODING ISSUES POSSIBLE FOR THE EASTERN GULF COAST.
BY SATURDAY NIGHT INTO SUNDAY, MOISTURE FROM THE NEXT PACIFIC
SYSTEM WILL BE SPREADING LOW-ELEVATION RAIN AND MOUNTAIN SNOW INTO
THE WESTERN HALF OF THE PACIFIC NORTHWEST.
BEHIND THE THIRD LOW PRESSURE SYSTEM, MUCH COLDER THAN NORMAL
CONDITIONS WILL OVERSPREAD THE SOUTHERN PLAINS THIS WEEKEND.
MEANWHILE, VERY MILD TEMPERATURES FOR MARCH WILL EXPAND ACROSS THE
NORTHERN TIER STATES BEHIND A WARM FRONT. IN CONTRAST, MILD
CONDITIONS ACROSS THE SOUTHEAST WILL SHRINK THIS WEEKEND AS THE
THIRD LOW APPROACHES FROM THE WEST. ACROSS THE SOUTHERN HIGH
PLAINS INTO SOUTHWESTERN TEXAS, VERY DRY AND GUSTY CONDITIONS
BEHIND THE LOW WILL SUPPORT CRITICAL FIRE DANGER INTO THIS
WEEKEND, WHERE RED FLAG/HIGH WIND WARNINGS AND WIND ADVISORIES ARE
IN EFFECT.
