Forecast Discussion

With the exact same setup in place, high pressure to our east and a low to our west, south-southwest winds will continue to push more heat and humidity our way. High temperatures today will slide up a few more degrees, likely into the lower and middle 90’s under plenty of humidity. Isolated showers and storms will pop up, but only west of the I-81 corridor this afternoon. Little relief will be felt overnight, as most of us only cool off into the 70’s.

It’s going to be a constant battle between the ridge of high pressure off the coast and the low to the west for the next few days. On Tuesday, the high pressure will have more of an influence, and that means lower rain chances and higher temperatures. Record temperatures don’t look to be broken, but with air temperatures pushing the middle and upper 90’s and humidity pushing the heat index close to advisory levels, it’s going to be sweltering. On Wednesday, the ridge lets up as the low slowly approaches from the north and west. It won’t be a total washout yet, but scattered showers and storms will be more possible in the afternoon.

By Thursday and Friday, the ingredients are going to finally come together to produce widespread rain and storms to end the week. The low and very slow moving front coupled with it will be overhead and then slide south during this time, as with all of the heat and available moisture it won’t be hard to spark up plenty of rain. This will thankfully cool us back down into the 80’s as the holiday weekend arrives. The big question will be if this system and front continue to push away or linger nearby for the 4th of July. There’s still a lot of spread in the models currently, but if the system lingers storms will remain possible for the holiday but if it keeps moving we’ll end up dry. With plenty of cookouts and celebrations likely planned, stick with us for the latest changes by the weekend.

Have a great Monday and stay cool and hydrated!
