We have been tracking an area of low pressure for a week now to impact us during the next few days. A warm front will begin to lift north tonight and tomorrow and position itself across southern Iowa. A wide range of temperatures will be across the front Tuesday. Northern Iowa will see highs in the upper 40s with southern Iowa near 70. Showers and thunderstorms will develop later tonight and continue on and off through Wednesday night. There will be a better chance of storms Tuesday. Here is the WPC forecast map for 1 pm Tuesday.

Apr 8 1 pm Tue Sfc Map
We will be on the northern edge of where some strong storms will be possible Tuesday. If any storms become severe it would be south of Cedar Rapids Tuesday afternoon and evening. The threat for severe weather will be mainly south of Iowa Tuesday and Wednesday (see map below).

Apr 8 Severe WX
We are still drought conditions across Iowa so the rain during the next two days will be beneficial. Also there is no longer any frost in the ground so the water will be absorbed into the ground. Rain amounts tonight through Wednesday evening could range from 1-3” (see map below).

Apr 8 QPFOnce the low moves east of Iowa it will pull cold air south and chance the rain over to light snow. Yes I just said there is a chance of snow. We have this chance Thursday. It is not unusual to have snow in April, but I am sure it not welcome. If you live north of Waterloo there is a chance of minor accumulations. Here are the chances of 1” of snow from Wednesday evening to Thursday evening.


The clouds will slowly clear Friday as high pressure move into the Midwest and provide more sunshine to region Saturday. Temperatures will warm back to the 50s by Sunday. We are tracking the next area of low pressure and cold front to bring a chance of showers/storms to area late Sunday into Sunday night.

April 8

TodayinWeatherHistoryFrom NWS
: A significant severe weather outbreak occurred across Iowa with 16 tornadoes touching down including two that produced F4 damage. One of these struck Slater and the other, which was a mile wide at times, passed through Taylor, Adams, Cass, and Adair counties. Farmsteads were swept clean to the ground and 12 people were injured. These were the last F4 or stronger tornadoes in the state until the F5 Parkersburg/New Hartford storm struck 9 years later. Large hail was also reported on this day, ranging up to golf ball size at several locations primarily in Guthrie and Dallas counties, and winds in excess of 80 mph were reported near Moravia and Sunbury. Strong winds also injured 5 people as vehicles were blown off I-35 between Ellsworth and Story City.

This Day in National/World Weather History …
 8 April 1993 → What was probably a waterspout struck land near the middle of Grand Isle, LA killing 3 and injuring 39 people.
 8 April 1998 → An F5 tornado smashed into Tuscaloosa and Jefferson Counties in Alabama, and came within 5 miles of downtown Birmingham. It was responsible for killing 32, injuring 258, and severely damaging or destroying more than 1,100 homes. It was the deadliest tornado in 50 years, while damage estimates were nearly $200 million. It was possibly the first time a local TV station went “wall-to-wall” with its coverage, meaning all programming and commercials were halted for continuous coverage of the tornado.
