Nov 23 Weather

What will the weather be like that weekend in Lee’s Summit Mo 2019?

Winter temps

I work out in the cold & this part of KC has been colder than normal since late October. The prediction for "colder temps" is correct to a degree but our February is twice as cold as any December we've ever had plus more precipitation than we've had since at least 2009. My prediction is a wet, wet year....worried about planting season now.

Weather

What is weather for midwest in April and May?
Really more Rainier than normal??? What's normal?

Forecast 8/31/19 and 9/7/19 in 66209 zip code
