...THERE IS A RISK OF SEVERE WEATHER FOR PARTS OF THE SOUTHERN
PLAINS/LOWER MISSISSIPPI VALLEY/TENNESSEE VALLEY/SOUTHEAST...

...COOL WEATHER WILL CONTINUE ACROSS THE NORTHEAST/GREAT LAKES AND
SPREAD ACROSS THE NORTHWEST US....

...RAIN WILL BE WIDESPREAD ACROSS MANY REGIONS OF THE COUNTRY
FOCUSING ON THE MIDDLE ATLANTIC STATES/OHIO VALLEY/MID MISSISSIPPI
VALLEY AND MUCH OF THE ROCKIES WITH MOUNTAIN SNOW...

A VERY SLOW MOVING WEATHER PATTERN WILL COVER MUCH OF THE COUNTRY
WITH A COUPLE OF STORM SYSTEMS BRINGING THE POSSIBILITY OF SEVERE
WEATHER, INCLUDING SEVERE THUNDERSTORMS, HAIL AND A FEW TORNADOES
OVER THE WEEKEND INTO MONDAY.

ONE STORM SYSTEM WILL MOVE FROM THE CENTRAL PLAINS EASTWARD ACROSS
THE OHIO VALLEY AND THE MIDDLE ATLANTIC STATES THROUGH SUNDAY.
SEVERE THUNDERSTORMS ARE POSSIBLE WITH THIS SYSTEM FROM THE
SOUTHERN PLAINS AND LOWER MISSISSIPPI VALLEY INTO SATURDAY AND
ACROSS THE TENNESSEE AND LOWER OHIO VALLEY INTO THE SOUTHEAST INTO
SUNDAY. ON THE NORTHERN EDGE OF THE STORM, A CHILLY RAIN WILL FALL
ACROSS THE MIDWEST AND UPPER OHIO VALLEY INTO THE MID ATLANTIC
STATES.

COOL WEATHER WILL CONTINUE TO PREVAIL ACROSS THE NORTHEAST AND
MIDWEST AND ONCE THIS FIRST STORM SYSTEM MOVES ACROSS, COOLER
TEMPERATURES WILL FOLLOW ACROSS THE LOW MISSISSIPPI VALLEY INTO
TENNESSEE VALLEY AND SOUTHERN ATLANTIC STATES.

ACROSS THE WESTERN HALF OF THE COUNTRY A COLD FRONT WILL WORK ITS
WAY SLOWLY SOUTH AND EASTWARD AND COOLER AIR WILL FOLLOW IN ITS
WAKE.  RAIN AND SNOW AT HIGHER ELEVATIONS WILL COVER MUCH OF THE
WESTERN US WITH SOME OF THE HEAVIER TOTALS IN MOUNTAINOUS AREAS OF
NORTHERN CALIFORNIA, UTAH, WYOMING, MONTANA AND COLORADO WHERE
RAINFALL OF .5 INCHES TO GREATER THAN AN INCH WILL FALL OVER THE
NEXT FEW DAYS.  SNOW WILL ALSO FALL ACROSS PORTIONS OF THE SIERRA,
THE WASATCH MOUNTAINS IN UTAH, ACROSS NORTHWESTERN WYOMING,
WESTERN MONTANA AND ACROSS PARTS OF IDAHO, AS WELL AS ACROSS THE
HIGHER PEAKS OF THE COLORADO ROCKIES.
