SHORT RANGE FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
341 AM EST FRI NOV 28 2014

VALID 12Z FRI NOV 28 2014 - 12Z SUN NOV 30 2014

***COLD ON FRIDAY FOR THE EASTERN U.S. THEN WARMING***

***BIG COLD FRONT ENTERING THE NORTHERN PLAINS***

***PLEASANT WEATHER CONTINUES FOR THE SOUTHERN TIER STATES***

THE EASTERN HALF OF THE U.S. WILL HAVE COLDER THAN AVERAGE
TEMPERATURES TO CLOSE OUT THE WEEK WITH AN UPPER TROUGH OVERHEAD
AND NORTHERLY WINDS.  WIDESPREAD 30S AND 40S ARE EXPECTED FOR
DAYTIME HIGHS, AND SUBFREEZING LOWS.  SOME LAKE EFFECT SNOW
SHOWERS ARE ALSO EXPECTED DOWNWIND OF THE GREAT LAKES.  WARMER
WEATHER IS FORECAST TO ARRIVE FOR THE WEEKEND AS THE COLD SURFACE
HIGH MOVES EASTWARD AND THE WIND BECOMES MORE SOUTHERLY.

ACROSS THE NORTHERN ROCKIES AND NORTHERN PLAINS, AN ARCTIC FRONT
SLOWLY SAGGING SOUTHWARD FROM CANADA WILL BRING MUCH COLDER
WEATHER FROM WASHINGTON STATE TO THE DAKOTAS FOR THIS WEEKEND.  A
SHARP DROP IN TEMPERATURES IS EXPECTED WHERE THIS FRONT PASSES
THROUGH.  THERE WILL ALSO BE WIDESPREAD LIGHT TO OCCASIONALLY
MODERATE SNOW WITH THIS FRONT, BUT THE GREATEST CONCENTRATION OF
HEAVY SNOW SHOULD REMAIN NORTH OF THE CANADIAN BORDER.

ELSEWHERE ACROSS THE CONTINENTAL U.S., NICE WEATHER WILL CONTINUE
FROM THE SOUTHWESTERN U.S. TO THE DEEP SOUTH WITH MOSTLY CLEAR
SKIES AND DRY CONDITIONS.  PERIODS OF RAIN ARE LIKELY FOR NORTHERN
CALIFORNIA AND OREGON WITH ONSHORE FLOW AND A COLD FRONT MOVING
THROUGH THE REGION.
