Hot & Humid May; How about June?

As you know, it has been quite hot and humid across the region of late. Not only that, but we have had plenty of showers and thunderstorms to contend with at times as well. That pattern can be blamed on the jet stream being positioned well to our north. That has and is still allowing warm and moist air to surge north from the Gulf of Mexico. As a result, we have seen high temperatures well above average in the 80s with dew points in the 60s to near 70°. So instead of May, it has felt more like July recently.

But as we all know, weather changes all the time. That statement will reign true regarding the heat and humidity. Once we get by Memorial Day Weekend and the beginning of next week, models begin to show a change in the upper levels of the atmosphere. This will be a change that features the jet stream dipping to our south. That means we will begin to see winds from the north, which translates to cooler and drier air. While models suggest this will happen into June, there is low confidence on when exactly this pattern change will begin to take shape locally. One model (the EURO) believes the change will occur by next Wednesday. The GFS model suggests it won't happen until after the first week of June. So it's something we will continue to monitor, but it is with decent confidence that we can say cooler air will move in eventually.
