Next Week's Lower 48 Heatwave Could Peak At 111F In Central Plains

It was in the 80s along Alaska’s Arctic Ocean shores yesterday. Record hot temperatures for a far northern region facilitated by factors related to human caused climate change such as warming ocean surfaces, sea ice melt, and an increasingly wavy Jet Stream.

But extreme heat along the northern reaches of Alaska appears now to be ready to morph into another record heatwave for the lower 48. For the past two weeks, weather models have been consistently predicting severe heat for the Central US. And with each passing day, as the forecasts grow evermore certain, the development of yet one more period of record hot temperatures becomes more and more likely.

An extremely tall dome of hot and heavy air is expected to build up over Colorado, Oklahoma and Nebraska. Heat beneath the dome and near the surface is expected to intensify. By the middle of next week, temperatures over a continuous large swath from Northern Texas to Montana and the Dakotas is predicted to experience near or above 100 degree F (38 C) temperatures. By late week, some of these readings could peak at around 111 degrees Fahrenheit (44 C) for parts of Central Nebraska.

These temperatures are expected to range 18-25 F (10-14 C) or more above typical July averages. And if temperatures do hit so high, they will likely make a number of new record highs for this region of the US. By Sunday, the heat is expected to sprawl both east and west. And high temperatures near or above the Century mark could ultimately stretch in a great triangle from Alabama west to the Central Valley of California and north to Montana’s Canadian Border.

1. Mid-Michigan has been miserably hot and dry, this summer

Any rain we've gotten has been brief, and of little good. On the bright side, as long as I can keep my veg garden watered, it's going to be a banner year for tomatoes.

2. Yeah, but it was warmer once, somewhere

So no worries eh?

3. Yes, the climate is always changing - just look at the end of the Permian!

Silly chicken-little treehuggers!
