VALID 12Z THU JAN 29 2015 - 12Z SAT JAN 31 2015

***MORE WINTRY WEATHER FROM GREAT LAKES TO THE NORTHEAST***

***MUCH COLDER WEATHER ARRIVING TO THE GREAT PLAINS STATES***

***MOISTURE INCREASING FOR THE SOUTHWESTERN U.S.***

AFTER A BRIEF RESPITE IN THE WEATHER FOR THE NORTHEAST AND
MID-ATLANTIC REGION, ANOTHER ROUND OF SNOW IS FORECAST FROM THE
UPPER GREAT LAKES TO NEW ENGLAND ON THURSDAY AND MOVING OFFSHORE
ON FRIDAY.  A MIX OF RAIN AND SNOW IS LIKELY FROM KENTUCKY TO
WASHINGTON DC SINCE TEMPERATURES WILL BE MORE MARGINAL IN THESE
AREAS.  THIS EVENT WILL BE CONSIDERABLY WEAKER THAN ITS MONSTER
PREDECESSOR A FEW DAYS AGO, WITH MOST LOCATIONS GETTING LESS THAN
SIX INCHES OF SNOW.  THE EXCEPTION WILL LIKELY BE OVER MAINE,
WHERE GREATER SNOWFALL AMOUNTS ARE POSSIBLE.

AFTER WIDESPREAD HIGH TEMPERATURES IN THE 70S AND EVEN LOW 80S
OVER THE CENTRAL AND SOUTHERN PLAINS EARLIER THIS WEEK, EXPECT
MUCH COOLER TEMPERATURES TO ARRIVE AS A STRONG SURFACE HIGH SLIDES
DOWN FROM CANADA BEHIND A COLD FRONT AND EXPANDS OVER MUCH OF THE
CENTRAL U.S. TO CLOSE OUT THE WORK WEEK.  HIGHS WILL BE CLOSER TO
AVERAGE FOR THIS TIME OF YEAR, ALONG WITH GUSTY WINDS.

CONDITIONS WILL BECOME INCREASINGLY WET OVER THE SOUTHWEST AND
FOUR CORNERS REGION FOR THE NEXT FEW DAYS WHILE AN ELONGATED UPPER
TROUGH EDGES INLAND OVER NORTHERN MEXICO AND STRONG LOW-LEVEL
WINDS ADVECT INCREASING PACIFIC MOISTURE TO THESE AREAS.  THIS
MOISTURE WILL FUEL WIDESPREAD MODERATE TO LOCALLY HEAVY
PRECIPITATION, WITH THE GREATEST AMOUNTS EXPECTED FOR ARIZONA AND
NEW MEXICO.  ACCUMULATING SNOW IS EXPECTED FOR THE HIGHER
ELEVATIONS OF UTAH, COLORADO, AND NEW MEXICO, AND A MIX OF RAIN
AND SNOW FOR THE HIGHER ELEVATIONS OF ARIZONA.
