yikes

oof, bitter much? not much you can do about the weather, but survive it.

I think it’s been pretty mild

I think it’s been pretty mild with the exception of this polar vortex. At least here in NW Iowa. Ppl seem to forget what doesn’t help their Argument. Climate change is also starting to drastically change weather cycles... and the predictions will have to be figured out depending on them.

weather

this is just normal winter weather for this part of the country. We have
had mild winters the last few years.

winter weather

True. People keep complaining about how bad the weather is, but it's pretty much what I remember from childhood in the 50's and 60's. We've been spoiled and have come to expect milder winters. Snow and cold is the norm for the Midwest. Climate change has been happening for thousands of years. We just happen to be living during the end of the most recent ice age (there have been many). Glaciers melting, water levels rising as a result. But then, every once in a while, we get a really cold, snowy winter. I realize I'm in the minority, but I like the snow and cold. It's easier to bundle up and keep warm than to try to keep cool during a hot and humid summer. We won't even talk about the insects!

ikr

totally it is 11 degrees right now and I'm freezing I can't even go outside because it's too cold

Weather Predictions 2019

According to the handy little chart provided by the Farmer's Almanac, we in the Midwest can expect cooler than normal temperatures in the hottest part of summer this coming spring. I have to keep myself contained as I'm already dreaming of fresh lettuce and spinach for my salad in July; and that NEVER happens. Yes, I know, "they" say never say never; but I'm telling you NEVER, not in Kansas. I so want to believe that I could have a growing season in which I don't have to start the lettuce and spinach in cold frames and hope against all hope that I have found the miraculous row covers that will protect my salad greens from bolting through June and maybe even until July 4th! I'd like to know how these predictions are made, using what data and their past accuracy? I can't very well scrap the cold frames, plan for succession planting, and revise my seed orders until I've gotten this information.

clarification

What do you mean by this sentence: "we in the Midwest can expect cooler than normal temperatures in the hottest part of summer this coming spring"?

Will we have a white Christmas?

I was hoping we could get a white Christmas I never had a white Christmas. It always snowed New Years Eve,

Bing Crosby: a forecasting genius or merely a dreamer?

It would help to know where you're planning to be at Christmas if your hopes are for an accurate prediction. I've lived in northeastern Kansas since the 1980s and have only experienced a handful of white Christmases. Nothing is ever halfway here, if we get "it" regardless of what "it" is, we get record amounts of it from tornadoes to tulips and everything in between. Truth be told, with climate change insisting upon rearing it's ugly head, unless you live in northern Canada, Alaska or at one of the poles, chances are that the only snowflakes you'll see at the end of the year are those paper ones we were forced to cut up as kids.
