830 PM CST TUE NOV 24 2009
A LOW PRESSURE SYSTEM MOVED ACROSS SOUTHERN IOWA ON TUESDAY AND WAS
LOCATED OVER SOUTHEAST IOWA ON TUESDAY EVENING. CLOUDS AND RAIN
ROTATED AROUND THE LOW...THEREFORE...MUCH OF THE UPPER MISSISSIPPI
RIVER VALLEY REGION SAW MOSTLY CLOUDY SKIES THROUGH THE DAY...WHILE
THE RAIN SHOWERS WERE OBSERVED ACROSS IOWA AND INTO EXTREME SOUTHEAST
MINNESOTA...THE SOUTHERN HALF OF WISCONSIN AND ILLINOIS. ALSO...A
WEAK FRONTAL BOUNDARY EXTENDED FROM THE LOW...NORTHWARD INTO
NORTHEAST MINNESOTA. ALONG THIS FRONT...LIGHT RAIN AND DRIZZLE WAS
SEEN THROUGH THE DAY. TEMPERATURES CONTINUED TO BE WELL ABOVE NORMAL
WITH AFTERNOON HIGHS IN THE 40S AND LOW 50S. LOCALLY...HIGHS RANGED
FROM 46 DEGREES AT MEDFORD WISCONSIN AND OELWEIN AND CHARLES CITY
IOWA TO 55 DEGREES AT SPARTA WISCONSIN.
FOR THE REMAINDER OF TONIGHT...THE AREA OF LOW PRESSURE WILL MOVE
INTO WISCONSIN...WHICH WILL SPREAD RAINFALL FURTHER NORTH AND EAST.
ALTHOUGH THERE WILL BE RAIN CHANCES ACROSS MUCH OF THE REGION...THE
MAJORITY OF THE RAIN WILL FALL IN AREAS CLOSER TO THE LOW...FROM
EASTERN IOWA INTO ILLINOIS AND WISCONSIN. MEANWHILE ANOTHER COLD
FRONT WILL PUSH ACROSS THE PLAINS BRINGING COOLER AIR AND MORE
PRECIPITATION CHANCES TO THE WESTERN PARTS OF MINNESOTA AND IOWA.
LOWS TONIGHT WILL RANGE FROM THE LOW 30S OVER THE WESTERN PARTS OF
MINNESOTA AND IOWA TO THE MID 40S IN SOUTHEAST WISCONSIN.
THE COLD FRONT WILL PUSH INTO WISCONSIN AND ILLINOIS ON WEDNESDAY...
THEREFORE TEMPERATURES ARE EXPECTED TO STAY NEARLY STEADY OR EVEN
DROP THROUGH THE DAY. PRECIPITATION CHANCES WILL CONTINUE ACROSS
MUCH OF THE REGION AS THIS FRONT PASSES BY..LEADING TO THE RAIN
MIXING WITH...AND POSSIBLY CHANGING OVER COMPLETELY TO SNOW IN SOME
LOCATIONS IN THE AFTERNOON. HIGH TEMPERATURES WEDNESDAY LOOK TO BE IN
THE UPPER 30S TO MID 40S.
THEN LOOKING TO WEDNESDAY NIGHT...TEMPERATURES WILL BE CLOSER TO
NORMAL...WITH LOWS RANGING FROM THE MID 20S TO THE MID 30S. SKIES
WILL REMAIN CLOUDY IN MOST AREAS...HOWEVER THE PRECIPITATION SHOULD
BEGIN SHIFTING EAST AS THE NIGHT PROGRESSES DUE TO BOTH SYSTEMS

THURSDAY...IT WILL BE POSSIBLE FOR SOME LOCATIONS ACROSS THE AREA TO
SEE SOME SNOW ACCUMULATIONS.
