Midsummer heat and humidity will not relent this weekend with temperatures continuing to run above normal courtesy of Atlantic high pressure pumping warm and moist air into the area while high pressure remains resident aloft for a few more days.

Heat and humidity continues for Friday and the weekend with high pressure aloft the main weather driver. Atlantic high pressure will continue to drive high dewpoints into the area, and that not only will drive heat indices well into the 100s, but it will keep us quite toasty at night, too. Expect lows in the upper 70s each day, perhaps not dropping below 80° closer to the coast and downtown.

High pressure rebuilding aloft will bring more sunshine — but more heat, too. We’ll start Thursday in the mid-70s inland to upper 70s near the coast. From there, plenty of sunshine will drive highs into the mid-90s. Dewpoints will be fairly juicy — generally in the mid-to-upper 70s — and this will drive heat indices well into the mid-100s. Closer to the coast as well as in downtown, dewpoints near 80° will help drive the heat index up toward 108° for at least a brief period. Heat Advisory criteria is a heat index 108°-112° for two hours or more, and we certainly could be close in the coastal corridor. Regardless, be sure you’re taking frequent breaks in the shade with plenty of water if you’re working outside.

The pattern turns a little more settled as high pressure builds back in aloft. As a result, we will see more sunshine as the week progresses, though with that will come warmer temperatures, too, which could push Heat Advisory thresholds in spots.
