..COOLING TREND SPREADS FROM WEST TO EAST THIS WEEK.
...FIRE WEATHER CONCERNS FOR PORTIONS OF SOUTHERN CALIFORNIA AND
TEXAS THROUGH MID-WEEK...
SYSTEMS MOVING BY THE NORTHERN INTERMOUNTAIN WEST BRING THE
PROMISE OF SNOWY PERIODS IN AND NEAR WESTERN MONTANA, IDAHO, AND
WYOMING THROUGH WEDNESDAY. THE FIRST OF THOSE SYSTEMS MOVES OUT
INTO THE MIDWEST, OHIO VALLEY, AND NORTHEAST, BRINGING RAIN AND
THUNDERSTORMS NEAR AND TO THE CYCLONE'S EAST, WITH THUNDERSTORMS
MOST LIKELY ACROSS PORTIONS OF THE EASTERN SHORE AND NEW JERSEY ON
THE AFTERNOON AND EARLY EVENING OF NEW YEAR'S EVE. AS THE CYCLONE
MOVES THROUGH THE NORTHEAST ON WEDNESDAY, BOTH LAKE EFFECT AND
LAKE ENHANCED SNOWS WILL SPREAD THROUGH THE GREAT LAKES AND INTO
THE NORTHERN AND CENTRAL APPALACHIANS. BETWEEN 6-12 INCHES OF SNOW
ARE FORECAST TO ACCUMULATE DOWNWIND OF THE LOWER GREAT LAKES BY
THURSDAY MORNING. SOME MIXED PRECIPITATION IS EXPECTED ACROSS
CENTRAL NEW ENGLAND.
A SYSTEM ARRIVING FROM THE GREAT PLAINS WILL PROMOTE SNOW SHOWERS
FOR THE BROADER GREAT LAKES REGION ON TUESDAY. A COOLING TREND
STARTED IN THE WEST EXPANDS EAST THROUGH THE REST OF THE COUNTRY
OVER THE NEXT COUPLE OF DAYS. BUILDING HIGH PRESSURE ACROSS THE
GREAT BASIN IS EXPECTED TO INCREASE WINDS ACROSS SOUTHERN
CALIFORNIA OVER THE NEXT COUPLE OF DAYS, PROMOTING AN INCREASED
FIRE WEATHER RISK WHICH COULD BECOME CRITICAL THROUGH MID-WEEK.
WIND ADVISORIES, A RED FLAG WARNING, AND A FIRE WEATHER WATCH HAVE
ALL BEEN POSTED FOR THE AREA AS WELL FOR PARTS OF SOUTH-CENTRAL
TEXAS THROUGH TUESDAY.
