It’s going to be another warm one out there to start the work week. Above average temperatures will once again persist today as highs will be in the low to mid 80’s for most locations. Scattered showers and thunderstorms will pop up tonight and last into tomorrow as a cold front moves through the region from the north.
By Wednesday, high pressure will settle in and we will also begin to see a significant change in the weather pattern. Over the past month or so, a large dome of high pressure aloft has been somewhat stationary over the south central and southeast US. As a result, the jet stream has stayed well to our north and above average temperatures have persisted. Quite frankly, it’s been downright oppressive. Beginning on Wednesday though, this upper level high will shift to the southwest, allowing for the jet stream to dip further south. You can see this illustrated in the image below.

Once this shift takes place, we’re finally going to see average temperatures for this time of year with highs in the mid to upper 70’s and dewpoints being lower as well. While that is still pretty warm, it’s MUCH better than what we’ve experienced lately. This is expected to be an extended event, so hopefully August will be kinder to us than July was.
Wednesday through Friday look to be quite pleasant as high pressure at the surface provides us with lots of sunshine. Precipitation chances increase Saturday as another cold front moves through.
