BUT SOME HAZARDOUS TRAVEL CONDITIONS ARE STILL EXPECTED WITH THIS
STORM SYSTEM THIS MORNING.

445 AM CST MON JAN 9 2006

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF EASTERN AND
CENTRAL MISSOURI AS WELL AS SOUTHWEST ILLINOIS.

.DAY ONE...TODAY AND TONIGHT

THERE IS A CHANCE FOR A WINTRY MIX OF RAIN...SNOW AND SLEET LATE
TONIGHT FOR PORTIONS OF SOUTHEAST MISSOURI...ROUGHLY ALONG AND
SOUTH OF A LINE FROM SPARTA ILLINOIS TO CUBA MISSOURI. NO SNOW OR
SLEET ACCUMULATION IS EXPECTED AT THIS TIME.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

A WINTRY MIX OF RAIN...SNOW AND SLEET WILL BE LIKELY ACROSS THE
AREA ON TUESDAY...ESPECIALLY DURING THE MORNING HOURS...FOR AREAS
ACROSS THE ST LOUIS METROPOLITAN AREA AND TO THE SOUTH AND EAST.
THIS IS DUE TO THE COLD START TO THE DAY AND WARM AIR BEING PUSHED
ALOFT BY AN APPROACHING STORM SYSTEM. ABOVE FREEZING SURFACE
TEMPERATURES AND RAIN EXPECTED TO BE THE PREDOMINANT PRECIPITATION
TYPE SHOULD LIMIT ANY SNOW ACCUMULATION TO LESS THAN A HALF INCH.

THE CHANCE FOR SNOW WILL CONTINUE THROUGH TUESDAY NIGHT AS THE
SYSTEM SLOWLY PULLS AWAY AND SOME COLDER AIR CAN WORK ITS WAY INTO
THE REGION. AGAIN...ONLY MINOR SNOW ACCUMULATIONS ARE EXPECTED WITH
LESS THAN AN INCH.

THERE IS AN ADDITIONAL CHANCE FOR SNOW ON FRIDAY AS ANOTHER SYSTEM
IMPACTS THE AREA.
