HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
300 PM CST SAT NOV 23 2002

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF IOWA...ILLINOIS...
AND MISSOURI.

.DAY ONE...

NO HAZARDOUS WEATHER IS EXPECTED.

.SPOTTER CALL TO ACTION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NECESSARY TODAY OR TONIGHT.

.DAYS TWO THROUGH SEVEN...

A LARGE RIDGE OF HIGH PRESSURE WILL BUILD DOWN ACROSS THE NORTHERN
PLAINS AND UPPER MIDWEST TONIGHT AND SUNDAY. THIS SYSTEM WILL ALLOW
COLD CANADIAN AIR TO SEEP DOWN INTO THE REGION...SETTING THE STAGE
FOR A CHILLY START TO THE WORK WEEK. AS THIS COLD DOME OF AIR SETTLES
ACROSS THE AREA...AN UPPER LEVEL DISTURBANCE WILL RIPPLE ALONG THE
SOUTHERN EDGE OF IT...BRINGING SNOW TO THE AREA SUNDAY AFTERNOON AND
EVENING. AT THIS TIME...IT APPEARS THAT THE BAND OF HEAVIEST
PRECIPITATION WILL EXTEND FROM SOUTHEASTERN KANSAS...THROUGH
SOUTHERN IOWA TO SOUTHERN MICHIGAN.  SNOW AMOUNTS OF 1 TO 3 INCHES
OF SNOW ARE POSSIBLE SOUTH OF INTERSTATE 80 TO ALONG THE
IOWA AND MISSOURI BORDER. NORTH OF INTERSTATE 80 AMOUNTS WILL TAPER
OFF TO AROUND AN INCH ALONG HIGHWAY 20. HOWEVER...THE PATH AND
STRENGTH OF THIS SYSTEM IS STILL SOMEWHAT UNCERTAIN...AS WELL AS HOW
MUCH MOISTURE IT WILL HAVE TO WORK WITH TO PRODUCE ACCUMULATING
SNOWS. THE SOUTHERN EXTENT OF THE COLD AIR DOME WILL ALSO COME INTO
FACTOR...AS WARM AIR TO ITS SOUTH WILL KEEP MUCH OF THE PRECIPITATION
AS RAIN.

...UPCOMING HOLIDAY OUTLOOK...
LOOKING AHEAD TO THE WEDNESDAY BEFORE THANKSGIVING...IT LOOKS LIKE
DRY TRAVEL CONDITIONS ACROSS EASTERN IOWA AND NORTHWEST ILLINOIS...AS
SNOW PRODUCING SYSTEMS PASS WELL TO THE NORTH AND SOUTH OF THE LOCAL
AREA. AS FOR THANKSGIVING DAY...A WEAK DISTURBANCE MAY CREATE SOME
LIGHT SNOW OR FLURRIES ACROSS THE AREA. TEMPERATURES WILL ALSO BE
MODERATING INTO THE UPPER 30S OR TO AROUND 40 DEGREES...ALLOWING SOME
RAIN SPRINKLES TO MIX IN WITH THE SNOW. THE DISTURBANCE CREATING THE
CHANCE FOR THE TURKEY DAY PRECIPITATION...WILL BE CLEAR OF THE
AREA FOR A DRY FRIDAY.
