SHORT RANGE FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
249 AM EST SUN DEC 10 2017

VALID 12Z SUN DEC 10 2017 - 12Z TUE DEC 12 2017

...LOCALLY HEAVY LAKE EFFECT SNOWFALL TO CONTINUE DOWNWIND OF THE
GREAT LAKES...

...CRITICAL FIRE WEATHER PERSISTING ACROSS SOUTHERN CALIFORNIA...

RELATIVELY QUIET WEATHER WILL BE IN STORE FOR MUCH OF THE COUNTRY
AS A WINTER STORM CONTINUES TO PULL AWAY FROM THE NORTHEAST SUNDAY
MORNING. A QUICK MOVING AND MOISTURE STARVED UPPER LEVEL
DISTURBANCE WILL BRING A CHANCE OF LIGHT SNOW SHOWERS TO THE
NORTHEAST TODAY/TONIGHT BUT THE GREATEST SNOWFALL ACCUMULATIONS
WILL BE EAST OF LAKES ERIE AND ONTARIO DUE TO LAKE EFFECT SNOW
WHERE LOCAL TOTALS UP TO A FOOT ARE FORECAST INTO MONDAY.

HEAVY LAKE EFFECT SNOW ACCUMULATIONS WILL ALSO BE POSSIBLE ACROSS
THE MICHIGAN U.P. MONDAY NIGHT INTO TUESDAY BEHIND A QUICK MOVING
CLIPPER SYSTEM. THIS CLIPPER IS EXPECTED TO DROP INTO THE
NORTH-CENTRAL U.S. TONIGHT BRINGING LIGHT SNOW, 1 TO 3 INCHES, TO
NORTHERN MINNESOTA AND WISCONSIN BY MONDAY AFTERNOON.

REGARDING TEMPERATURES, THE EAST COAST WILL BE 5-15 DEGREES BELOW
AVERAGE TODAY WITH SOME MODERATION ON MONDAY. MOST OF THE PLAINS
WILL BE 10 TO 25 DEGREES ABOVE AVERAGE TODAY AND MONDAY WITH
WESTERLY TO NORTHWESTERLY DOWNSLOPE WINDS AT THE SURFACE. WINDS
WILL ALSO BE GUSTY AT TIMES, ESPECIALLY ON MONDAY AFTER THE
PASSAGE OF A COLD FRONT TIED TO THE AFOREMENTIONED CLIPPER SYSTEM.
THESE WINDS WILL ALSO GENERATE DRY CONDITIONS LEADING TO AN
ELEVATED RISK FOR WILDFIRES EXTENDING THROUGHOUT PARTS OF THE
SOUTHERN AND CENTRAL HIGH PLAINS THROUGH MONDAY.

THE GREATER RISK OF WILDFIRES WILL BE ACROSS CALIFORNIA THOUGH,
WHERE CRITICAL FIRE WEATHER CONDITIONS WILL PERSIST THROUGH AT
LEAST MONDAY GIVEN CONTINUED STRONG SANTA ANA WINDS AND LOW
RELATIVE HUMIDITIES.
