...MAJOR WINTER STORM AFFECTING PARTS OF THE CENTRAL U.S. AND
UPPER MIDWEST THROUGH MONDAY...

A WINTER STORM SYSTEM IS IMPACTING MUCH OF THE CENTRAL U.S. THIS
WEEKEND. WIDESPREAD FREEZING RAIN WILL PERSIST FOR MUCH OF WESTERN
OKLAHOMA, KANSAS, NORTHERN MISSOURI AND WESTERN IOWA TONIGHT AS
WARM ADVECTION ALOFT OVERRIDES SUB-FREEZING TEMPERATURES AT THE
SURFACE.  ICE STORM WARNINGS, FREEZING RAIN ADVISORIES, WINTER
STORM WARNINGS AND WINTER WEATHER ADVISORIES IN EFFECT FROM
NORTHERN NEW MEXICO TO SOUTHERN MINNESOTA/WESTERN WISCONSIN.  THE
NORTHERN EDGE OF THE PRECIPITATION SHIELD, SPANNING FROM EASTERN
COLORADO TO SOUTHERN MINNESOTA, WILL LIKELY HAVE SIGNIFICANT
ACCUMULATIONS OF SNOW AND SLEET WITH THIS SYSTEM. PORTIONS OF THE
SOUTHERN PLAINS AND LOWER MISSISSIPPI VALLEY WILL HAVE PERIODS OF
HEAVY RAIN, WHICH MAY INCREASE THE THREAT FOR RAPID RUNOFF. FLASH
FLOODING WILL BE POSSIBLE FOR TEXAS, ARKANSAS AND NORTHWEST
LOUISIANA THROUGH TUESDAY.

RAIN AND MOUNTAIN SNOW IS FORECAST FOR PORTIONS OF THE PACIFIC
NORTHWEST BY MONDAY NIGHT AS STRONG ONSHORE FLOW FROM THE NEXT
APPROACHING STORM SYSTEM. STRONG HIGH PRESSURE OVER THE GREAT
BASIN/INTERIOR WEST WILL KEEP CONDITIONS MAINLY DRY AND MILD. ONCE
THE CURRENT SYSTEM OVER THE CENTRAL U.S. MOVES EASTWARD, RAIN AND
POSSIBLY A FEW THUNDERSTORMS WILL ARRIVE TO THE EASTERN STATES BY
TUESDAY MORNING.
