A FRONTAL BOUNDARY TO OUR SOUTH WILL LIFT NORTH TONIGHT AND MONDAY AND BE TO OUR NORTH BY MONDAY AFTERNOON. ANOTHER FRONTAL SYSTEM WILL APPROACH NWRN IOWA BY MONDAY NIGHT AND TUESDAY.
THE FRONT TO OUR SOUTH WILL CONTINUE TO BE THE FOCUS OF SHOWERS/STORMS THROUGH THE NEXT 24 HOURS. RAINFALL WILL BE MORE ISOLATED TO SCATTERED ACROSS ALL OF IOWA TODAY AND TONIGHT RATHER THAN WIDESPREAD AS WAS THE CASE OVERNIGHT.
AS THE FRONT PUSHES NORTH MONDAY...THE RAIN WILL LIFT TO THE NORTH AS WELL. MUCH WARMER AIR WILL STREAM NORTH INTO CENTRAL IOWA IN THE WAKE OF THE FRONT. TEMPERATURES WILL EASILY REACH THE MID 80S SOUTH OF IT MONDAY AFTERNOON.
THE REST OF THE WEEK LOOKS TO BE ACTIVE WITH A SERIES OF FRONTAL SYSTEMS ADVANCING THROUGH NRM IOWA/MN, PUTTING US IN A RAINY CYCLE EVERY TWO TO THREE DAYS. TEMPERATURES WILL BE CLOSE TO SEASONAL NORMALS FOR LATE SEPTEMBER.

Where has the summer gone??????
The air may already feel like autumn across parts of the United States, but there are still a few days left until the official end to summer. Summer officially comes to a close Wednesday (22 Sept) evening at 11:09 p.m. EDT, when the sun will be directly over the equator. From that point until the Winter Solstice, the sun will appear to migrate southward to the Tropic of Capricorn.
On this day in Iowa weather history...
1991: Unseasonably cold weather brought freezing temperatures to nearly every portion of Iowa on the mornings of September 19th and 20th. On the morning of the 19th the coldest air settled over northwestern Iowa where temperatures dropped to as low as 24 F at Hawarden, Sibley, and Sioux Center and some locations remained at or below 30 degrees for nearly eight hours resulting in severe crop damage. By the morning of the 20th the coldest air had moved over about the eastern two thirds of the state with temperatures bottoming out at 27 F at Cresco, Elkader, Fayette, Grinnell, Manchester, Oskaloosa, and Waterloo. Generally the only areas to escape the freeze were some of the urban centers, upland areas of southern Iowa, and portions of the Mississippi River valley. Nevertheless this was the earliest statewide freeze to occur in Iowa in more than a century.
