10.10.2020 wedding

Wedding in Northern IL oct 10th..... what's weather look like? Thank you

outdoor wedding

What will it look like October 26th for an outdoor ceremony?

Wedding weather October in Omaha

I’m planning a backyard wedding for October 17th in Omaha, NE. Any idea what the weather might be like that day?

November 21st Wedding

Might have to move our wedding... again due to covid. We are debating on keeping the date but moving the location to our farm outdoors! A little nervous but what do you think the weather will be like


You got July completely wrong!

40th class reunion

I am planning a 40th class reunion for March 19-20, 2021, all outside activities. Can you be so kind to give me your prediction for those days. Thank you in advance.

Rain for tree reforestation


My great grandparents were long time subscribers to your predictions and I have never found myself in need until this year. I have actually inherited their old home in northeast Missouri and decided to work on reforesting an acre of land. I have planted 300 bald cypress, sweetgum and swamp white oak in an area that often floods in the spring due to poor drainage in the soil. I have found myself fearful of what will happen if we run short on rain this year for any length of time as these are small tree seedlings with small roots and it is not a feasible option to continuously water 300 trees where they are located. Would you expect there to be 1" of rain per week throughout this growing season? I really appreciate your feedback as I am thinking about learning how to do some rain dances :D.

Moving long distance

From June 4-6 wondering what the weather will be like in Missouri to Houston. It’s not fun moving in the rain.

Swimming Pools

Hi, every year my family and I always look to see what the future summer forecast will be to determine whether or not we should put our above ground pool up. Would you say this summer will be a warm summer for an above ground pool to be up? Due to Covid-19, and the possibility that we may still be at home, having the pool up would be great get-a-way for the kids.


everybody in the pool!

Hi, Nickkie, For the Heartland we are predicting both temperatures and precipitation to be slightly above normal, so you should expect some fine days for fun in the pool. Best to you all!
