SHORT RANGE FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
249 AM EST MON JAN 16 2017

VALID 12Z MON JAN 16 2017 - 12Z WED JAN 18 2017

...BIG LOW PRESSURE SYSTEM AFFECTING PARTS OF THE CENTRAL U.S. AND
UPPER MIDWEST THROUGH MONDAY...

THE LARGE LOW PRESSURE SYSTEM CURRENTLY OVER THE CENTRAL PLAINS
MONDAY MORNING IS PRODUCING AN EXPANSIVE AREA OF PRECIPITATION,
AND THIS IS EXPECTED TO CONTINUE OVER THE NEXT TWO DAYS AS THE LOW
PROGRESSES TOWARDS THE NORTHEAST.  PERIODS OF HEAVY RAIN AND
THUNDERSTORMS ARE LIKELY FROM EASTERN TEXAS TO SOUTHERN MISSOURI
ON MONDAY AHEAD OF THE COLD FRONT.  FARTHER TO THE NORTH FROM
EASTERN COLORADO TO WISCONSIN, IT WILL BE IN THE FORM OF WINTRY
WEATHER, WITH FREEZING RAIN AND SLEET FROM KANSAS TO IOWA, AND
SNOW ON THE NORTHERN PERIPHERY OF THE PRECIPITATION FROM COLORADO
TO NEBRASKA WHERE THE COLD AIR IS DEEPER.

THE WEATHER PATTERN ACROSS THE PACIFIC NORTHWEST WILL BECOME QUITE
ACTIVE AGAIN BY TUESDAY WITH HEAVY RAIN AND MOUNTAIN SNOW,
COMPLIMENTS OF STRONG ONSHORE FLOW FROM THE NEXT APPROACHING STORM
SYSTEM OVER THE NORTHEAST PACIFIC OCEAN.  BY WEDNESDAY, THIS
MOISTURE SHOULD BEGIN REACHING CALIFORNIA AND THE NORTHERN
ROCKIES, WITH THE HEAVIEST RAIN EXPECTED FOR THE COASTAL MOUNTAIN
RANGES FROM NORTHERN CALIFORNIA TO WASHINGTON.  STRONG AND GUSTY
WINDS ARE ALSO LIKELY NEAR THE COAST AND FOR THE HIGHER ELEVATIONS.

FOR THE EAST COAST, EXPECT THE NEXT CHANCE OF NOTEWORTHY
PRECIPITATION TO ARRIVE BY TUESDAY MORNING AS THE CENTRAL PLAINS
STORM SYSTEM STARTS AFFECTING THE REGION, BUT WITH MUCH LESS
WINTRY WEATHER BY THAT TIME.  TEMPERATURES SHOULD ALSO MODERATE BY
THE MIDDLE OF THE WEEK WITH READINGS GENERALLY ABOVE SEASONAL
AVERAGES FOR MANY AREAS.
