Today will be considerably cooler than yesterday, thanks to east winds and more clouds. Highs will struggle to reach 40. Drizzle and fog develop tonight; some freezing drizzle is possible mainly north of US 20. Sunday will be mild in the 50s with showers and fog. After Monday, though, very cold air surges southward, along with snow on Wednesday.
CLOUDS WILL CONTINUE TO INCREASE THROUGHOUT THE DAY...WITH A LAYER OF LOW STRATUS DEVELOPING ACROSS THE AREA TONIGHT. LOW LEVEL MOISTURE WILL MOVE INTO THE STATE FROM THE SOUTH AS AN AREA OF LOW PRESSURE APPROACHES. THIS WILL BRING THE POTENTIAL FOR DRIZZLE TO MUCH OF THE STATE - WITH FREEZING DRIZZLE POSSIBLE ACROSS PORTIONS OF NORTHERN IOWA WHERE TEMPERATURES WILL DIP INTO THE UPPER 20S TO AROUND 30 TONIGHT. CHANCES FOR PRECIPITATION CONTINUE ACROSS THE AREA INTO SUNDAY AND MONDAY MAINLY ACROSS THE NORTHERN 1/2. COLDER AIR WILL MOVE INTO POW CTY AS WELL...WITH CHANCES FOR SNOW IN NORTHERN IOWA MONDAY. ANOTHER STORM SYSTEM IS TAKING SHAPE TOWARD MID WEEK WITH ADDITIONAL CHANCES FOR SNOW AND WIND LATE TUESDAY, WEDNESDAY, AND INTO THE THANKSGIVING MORNING.
