Natural Air Conditioning.....

What a beautiful couple of days we have ahead of us, unseasonably cool highs, along with a relatively dry air mass to enjoy. Now, we won't be able to repeat this performance throughout the year, so let's take advantage of it while we can. At least our upper level air pattern is on our side. I have included two pictures of the upper level wind flow around 17,000 ft for you to study.


The first picture shows the current location of our jetstream. A dominant ridge is holding the heat out over the west, while a trough begins to deepen over the Great Lakes. Typically, we would see that ridge build over our area after the passing of the trough; however, take a look at what happens in the second picture. An upper level low becomes cut off from the main jetstream, and this low deepens across the southeast, creating a northeasterly flow at the surface. This low will act as a temporary blocker from the heat.
This is what I call a natural air conditioning pattern. As long as that low sits to our east, we'll be able to hold off the heat. Unfortunately, the cut off low is forecast to move east, and we'll eventually warm back up toward the weekend.
