Wedding Weather - August

Hello! I’m planning a wedding for early to mid-August between Lincoln and Beatrice Nebraska. Can you give me predicted precipitation and temperature for that timeframe? Or even specifically August 8 and 15!

Thank you!

April 10th 2020 wedding

I am having a (hopefully) outdoor wedding on April 10th in Carthage, Missouri. Could you give me a prediction of the weather that day? Thank you!

Wedding

My daughter is having her wedding reception April 11, 2020 in downtown Lincoln, Nebraska. Can you please give me a prediction of how the weather may be that day? The actual ceremony is hoping to be outdoors between LIncoln and Seward Nebraska at a winery. Thank you!

Seed Savers

Mid-October is the end of the gardening season in the Decorah, IA area. There will likely have been a killing frost by then, and most of the demonstration garden areas shut down by the time of your visit. You could still tour the farm, see the White Park cattle, and enjoy the Lillian Goldman visitor's center, which is a beautiful building. The weather will be cool so bring warmer clothes to be outside. You could always call them before your visit and ask them what activities are available.

Mid-October 2020

We are having a family reunion in the area of Decorah, Iowa October 14, 2020. We especially want to visit Seed Savers while we are there. Will they have had a frost by then? What temperatures can we expect?

In STL

For that last comment - I should have clarified for St. Louis, MO. :) Thanks!
