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

Planning an outdoor party.

One week were in tee shirt weather and the next in 10 layers of clothing lol.

Couldn't be more wrong

How is this a mild winter? Seems we're having the coldest temperatures ever here in the midwest. It's colder in the midwest than it is in Alaska! School has been cancelled for 6 days so far.
