VALID 12Z SAT JAN 31 2015 - 12Z MON FEB 2 2015

***UNSETTLED WEATHER FOR THE SOUTHWESTERN U.S. ON SATURDAY***

***DEVELOPING STORM SYSTEM OVER CENTRAL U.S. THIS WEEKEND***

***WIDESPREAD SNOW FROM THE OHIO VALLEY TO NEW ENGLAND***

THE BROAD UPPER LEVEL TROUGH WITH EMBEDDED SHORTWAVES OVER
NORTHERN MEXICO AND THE DESERT SOUTHWEST CONTINUES TO KEEP
SCATTERED SHOWERS IN THE FORECAST ON SATURDAY FROM EXTREME EASTERN
CALIFORNIA TO NEW MEXICO.  SNOW SHOWERS ARE EXPECTED FOR THE
HIGHER ELEVATIONS OF THE FOUR CORNERS REGION.  THE WEATHER HERE
SHOULD IMPROVE BY THE END OF THE WEEKEND AS THE UPPER LEVEL
DISTURBANCE LEAVES THE REGION.

MOISTURE FROM THE SOUTHWESTERN U.S. FEATURE, ALONG WITH SOUTHERLY
FLOW FROM THE GULF OF MEXICO, WILL COMBINE WITH A DEVELOPING
SURFACE LOW OVER THE CENTRAL PLAINS LATE ON SATURDAY TO PRODUCE
WIDESPREAD PRECIPITATION OVER THE CENTRAL U.S.  RAIN IS EXPECTED
FROM KANSAS TO THE DEEP SOUTH, AND A BAND OF LIGHT TO MODERATE
SNOW NORTH OF THE SURFACE LOW TRACK.  ONCE THE SYSTEM DEVELOPS
FURTHER AND REACHES THE MID-ATLANTIC REGION BY MONDAY MORNING,
WIDESPREAD ACCUMULATING SNOW IS FORECAST FROM THE OHIO VALLEY TO
SOUTHERN NEW ENGLAND, WHERE NUMEROUS WINTER STORM WATCHES ARE
CURRENTLY IN EFFECT AT THE TIME OF THIS WRITING.

ELSEWHERE ACROSS THE CONTINENTAL U.S., EXPECT DRY CONDITIONS TO
CONTINUE FOR MOST OF CALIFORNIA THROUGH MONDAY.  RAIN AND SNOW
CHANCES INCREASE FOR THE PACIFIC NORTHWEST BY SUNDAY AS A WEAK
COLD FRONT APPROACHES THE COAST.  MOST OF THE NORTHERN U.S. WILL
CONTINUE TO HAVE BELOW-AVERAGE TEMPERATURES FOR THIS WEEKEND.
