***Official 2024 Weather Thread***

One of my window wells started filling up and water came in through the window. Luckily it was the one in the unfinished part of the basement and closest to the floor drain. Only had to move a rug and couple of totes.

I had that happen in 2019. Only the entire window well filled up with water (windows must have had a great seal) and eventually burst. Unluckily for me it was a finished basement (guest room). About 10k of damage, insurance paid out nothing (water originated outside of the house).

I've replaced the flat drain that was clogged with a dome shaped grate and had our entire back yard re-graded. The city also redid the grading behind our property (where the water came from to begin with).

Surprised Ankeny isn't running the sirens yet...

Anyone know of a place my son could park his pickup during the storm? :) He's a student at ISU, but would come to Ankeny. I'm guessing Costco after they close and before they open. Not sure if they monitor or not. He's worried about hail.
Parking at the MU ramp for 24 hrs is $20. That is always an option
 
No. Violet and indigo are on the other end of the rainbow. So they must be less severe than even the green and blue. There’s no way a scientist like a meteorologist would screw up something as basic as ROYGBIV.

Funny story: I never learned about ROYGBIV until I was like 35 years old.
 
Feel like we have a couple storms per year were the word 'derecho' gets thrown around. None of them come close to resembling the storm in 2020.
It is important to remember the 2020 derecho was an extreme ESPECIALLY for those of us in Iowa and the CR area. It did not produce those winds for it's entire duration.

Paul Douglas just mentioned the D-word here in Mpls. Doesn't carry the same weight as it does now for you guys after 2020 but it caught my eye.

Man I feel bad for SE Iowa. They are getting pounded
We spoke to our real estate agent in Bloomfield this morning and she said they had 4 inches, with some wind. Went by our house for sell, she was worried the basement had water, but she said it was dry, no water and everything looked good.

When the 2020 derecho hit, wasn't it only like the second or third one in 20 years or something? Now predictions of derechos seem to get dropped pretty regularly.

We had one in 2011 and 2020 in Marshall County. Don't remember any other storms that were called derechos...but I am very old so I may have forgotten, ;)

They happen more often than people think, it’s just not a term like tornado that everyone knows

Sorry, I meant in Iowa, not in general. Even on that list there aren't that many in Iowa, and I've seen predictions for possible derechos at least a few times this year alone. So we've either had a sharp increase in conditions for derechos in the span of just a few years, or some forecasters are becoming too reliant on that word.

Probably a bit of both, but the earth is also hotter than ever…

And maybe they can just do it by estimated max wind speed instead of stupid damage assessments.

Well, tornado damage assessments are the best way to estimate the max wind speed of a tornado at ground level. Nowadays, radar might be able to get you an estimated wind speed at elevation, but ground level wind gauges aren't going to give you that kind of data.

Tornado fajita levels are after the fact as well. Its not like you can forecast an individual tornado. Forecast do account for size by saying "large, damaging tornados" or "small spinup tornados" possible.

Hurricanes are slower, so you can forecast what they think it will be in the future.

A derecho could be forecast as well, although I think the VAST majority of Derecho's probably fall into the 58-80mph forecast. We saw one a week or so ago where as it was going and they got wind speed reports over 90, so the bumped up the warnings. But if they did do something like CAT 1=58-70, CAT2 =70-90, etc, it might be easier for people to understand.

There’s just one thing that drives me away from damage assessments. And that is the “if a tree falls in the woods does it make a sound?” phenomenon. “If a tornado doesn’t hit a man-made object, was it even a tornado?”.

If he is in Ames go to the MGMC ramp. My sis has done that with her truck when hail is predicted.
