We are tracking a few rounds of severe storms possible through Thursday night. The first round would be very late tonight. Storms are possible after 3 AM Thursday into mid morning, about 10 AM. The primary threat would be damaging wind and heavy rain.
The second round of possible severe storms would be after 5 PM Thursday to about midnight. All forms of severe are possible with this round including tornadoes, high winds, hail and heavy rain.
The humidity level remains high through Thursday night and becomes a bit more comfortable Friday through the weekend. Dry weather and cooler temperatures are expected during this time as well. The humidity level and temperatures increase early next with with a few storm chances.

We are tracking storms forecast to move through eastern Iowa tonight…mainly after 9 or 10 PM. An isolated shower or storm is possible before this time, but the more widespread storms will be after and through the overnight. Heavy rain, damaging wind and large hail are the primary threats with the storms. The storms are forecast to end between 4-6 AM Wednesday.
Most of Wednesday is dry with a slight chance of an afternoon shower/storm. High temperatures remain in the mid-upper 80s and humid. We are tracking another round for storm possible for late Wednesday night into Thursday morning. Again the main threat of any of the storms would be heavy rain, damaging winds and large hail.
Friday through Sunday is dry, a bit cooler and less humid before the heat and humidity with storm chances return early next week.

A warm front, southwest of Iowa early this afternoon, is forecast to move northeast across the state.
As it does, rain and storms will develop later this evening. The storms are expected to develop around 10 or 11 pm and become widespread in just a couple of hours. The initial storms could produce large hail and heavy rain. Then the threat turns to more of a flooding rain situation. Widespread 1-2″ of rain is expected with isolated higher amounts to near 5″. This is the reason why a Flash Flood Watch is in effect tonight.
The storms will be widespread overnight and eventually ending between 7-9 AM Wednesday.

A Severe Thunderstorm Watch is in effect for the counties along the Iowa/Minnesota border until 9 PM.
The primary threat would be large hail and damaging wind with any of the storms. The timing of the storms would arrive in this area between7-9PM.
Once the storms move south into Iowa, they are forecast to weaken quickly and in some cases fall apart completely. Any rain/storm chance would occur before midnight tonight. It remains warm and humid overnight.
Saturday is almost a repeat of Friday when it comes to the heat and humidity. The sky will be mostly sunny most of the day. Between 3-7 PM there is slight chance for a few storms to develop. At this point a severe storm is possible if they develop. The storm chance lingers into the overnight, but in an isolated fashion.
Sunday is still humid and slightly cooler by about 5-8 degrees. A mix of sun and clouds are expected.
The weather pattern becomes a bit more active next week with a chance of storms each day. Temperatures cool into the low -mid 80s, but the humidity level remains high.

A warm front is going to be moving across Iowa tonight and Thursday morning. A few showers/storms are forecast along this front. No severe weather is expected. Any storms that develop will have locally heavy rain, gusty wind and the potential for small hail. Here is the radar this evening.
Here is the forecast position of the warm front across Iowa Thursday morning. A few storms are possible in the morning. Behind the front the temperatures will increase and so does the humidity level.
