THE WEEKLY - June 24 - 30

Last week THE WEEKLY talked about how that dome of high pressure moved east and allowed a stormy pattern to take over. Well guess what? High pressure is coming back, and it could be the first true heatwave of the season for most of the eastern US.

Before we get to the big heat and humidity we have to make our way through one more storm system that'll move through on Wednesday:

A storm system from the northern Plains will head our way, firing daytime storms along the cold front and also well out ahead. Above is the NAM simulated radar from Tuesday night where you can see a storm complex that develops out in the hot and humid warm sector. I think we'll deal with some overnight storms Tuesday before getting the frontal storms Wednesday. Already a couple days out I can imagine our Wednesday storms will depend on how quickly our atmosphere recovers from leftover morning storms.

After that, prepare for the torch:

We're about a week out from the start of the really hot weather, but from this temperature anomily map you can tell the heart of this heat wave will be centered over the Great Lakes. The 8-10 day time frame has all the making of extreme heat, one that I feel confident right now saying we will probably see triple digits then or soon after. We could be in high heat through the second week of July.

We haven't experienced a true heat wave like this in a while. Summer of 2012 is the last time I remember something this extreme setting up. 

But keep in mind, it's still a week away, so this isn't set in stone. Many jumped the gun and thought our mini heat wave last week would be bigger, too. For right now I want to be conservative, like I usually am, but a hot a dry pattern seems more likely than not.

If storms become strong on Wednesday I'll post. Otherwise expect another post before next Sunday about our potential heat wave.
