Expiration: 615 AM CST MON DEC 21 2009
THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHWEST...NORTH CENTRAL
AND WEST CENTRAL MISSOURI...AS WELL AS EXTREME EASTERN KANSAS.
.DAY ONE...TODAY AND TONIGHT
THERE IS A SLIGHT CHANCE OF SNOW IN AREAS FROM UNIONVILLE TO
LANCASTER AND KIRKSVILLE TODAY AS A CLIPPER SYSTEM MOVES FROM IOWA
INTO ILLINOIS. ANY SNOW AMOUNTS WOULD BE LIGHT.
.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY
A COMPLEX STORM WILL BE DEVELOPING FOR THE MIDWEEK TIMEFRAME AND MUCH
UNCERTAINTY REMAINS ON THE TRACK...SPEED...AND HOW MUCH WARM AIR
WILL BE FED INTO THE SYSTEM. FORECASTS SHOULD BECOME MORE CERTAIN AS
THIS SYSTEM MOVES ONSHORE IN THE NORTHWEST ON MONDAY.
INITIALLY ON TUESDAY WELL AHEAD OF THE MAIN STORM...LIGHT PATCHY
DRIZZLE...FREEZING DRIZZLE OR LIGHT SNOW MAY OCCUR AS MOISTURE AND
WARMER AIR START RETURNING. HOWEVER...THE EFFECTS OF THE MAIN STORM
SHOULD NOT START TO AFFECT THE REGION UNTIL TUESDAY NIGHT AND
WEDNESDAY.
TUESDAY NIGHT...THERE IS THE POTENTIAL FOR FREEZING RAIN
OR SNOW...WHICH SHOULD BE TRANSITIONING TO RAIN ON WEDNESDAY AS
WARMER AIR IS PULLED NORTHWARD. THE AREAS NEAR THE IOWA AND NEBRASKA
BORDER MAY NOT WARM ENOUGH TO GET ABOVE FREEZING AT THE SURFACE
DURING THE DAY ON WEDNESDAY...SO ICING OR SNOW MAY BECOME A PROBLEM.
WEDNESDAY NIGHT...AS THE STORM TRACKS NORTHEAST TOWARD MISSOURI...RAIN
OR SNOW WILL BE POSSIBLE...AND DEPENDING ON THE EXACT
TRACK...SIGNIFICANT SNOW ACCUMULATIONS COULD START OCCURRING TO THE
NORTHWEST OF THE STORMS TRACK. AT THIS TIME...THE BEST ESTIMATE ON
WHERE A HEAVIER BAND OF SNOW MIGHT FALL IS FROM EASTERN KANSAS ACROSS
NORTHWEST AND NORTH CENTRAL MISSOURI INTO IOWA.
ON THURSDAY...SNOW WILL REMAIN POSSIBLE ON THE BACK SIDE OF THE
EXITING STORM.
.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION WILL NOT BE NEEDED. BUT REPORTS OF SNOW AND ICE
WILL BE NEEDED WITH THE STORM SYSTEM MOVING THROUGH MIDWEEK.
