Late week heat, humidity, and storms!

This is still quite a ways out, but here is your heads up. Through this week, high pressure will move south and anchor over the Southeastern US. This will create a persistent flow of Gulf moisture into the central US by Friday and is expected to last through the weekend.

What does this mean for us?
Humidity will climb for Friday and the weekend. Highs will be in the 80s and we will have a Heat Index to talk about. Potential Heat Index values could climb into the 90s!
Also, storm chances will return. Friday and everyday after that will have a chance for storms. We will continue to see rain chances until this weather patter breaks!

Other details will come into focus as we get closer. The severe weather threat could also return but it is undetermined at this time.

Racing season is back!

It has been a busy stretch of severe weather. Below are all the Tornado (red) and Severe thunderstorm (yellow) warnings that were issued between Friday the 15th through Monday the 18th. I am happy to say we are catching a break from severe weather for the rest of the week.

More storms tonight!

Great morning for a long run!

I’m not there yet, but I will be ready for ya EMC DAM to DSM

Only 2 weeks away!!!

We are still set to have a stormy evening/night!
Strong winds and large hail are the primary threats.

A Severe Thunderstorm Watch is in place for much of the NW 2/3rds of Iowa until 1:00am. Main threats are very large hail and damaging winds.

80s and 90s? It’s a great day for some Skyline Ice Cream!

Monday, May 18th could be the day with the strongest storms out of stormy stretch.

Monday will likely bring the highest and most widespread severe risk to the state. Some storms could be ongoing Monday morning, but will likely move out by midday, allowing the atmosphere to heat back up and recharge for a potentially stronger round in the afternoon. A front will be moving into Iowa helping to give a focus for storm development. The storms will likely develop in western Iowa during the late afternoon or evening, and then push east into central Iowa. Some significant severe weather is possible in the form of large hail, damaging winds, and a higher tornado risk. Heavy rainfall will be likely as well.

Below is a graphic showing were the Storm Prediction Center would place an Enhanced Risk (3 out of 5 chance for severe weather). This goes to show how strong the severe weather signal is for the beginning of next week.

If you have plans Sunday, you will still need to keep an eye on the radar through the day.

Non-severe showers and storms are expected to linger into Sunday morning which could inhibit stronger storm formation for parts of the afternoon and evening. This is the day that holds the highest amount of uncertainty for this reason. If conditions become favorable, Sunday late afternoon into overnight could generate another round of strong to severe thunderstorms. The current timeframe that seems most likely based on the current model data is Sunday night. Storms will be expected to develop over Nebraska, and then push east into Iowa. All modes of severe weather will be possible during this time with hail and wind being the highest threat. The strongest signal for severe weather will be in western and northwestern Iowa with most of the state covered in the 2 out of 5 chance for severe weather.
