8/7 – Rob’s HOT & HUMID Weekend Forecast
The area remains in a northerly flow aloft…which will help prevent widespread convection today. What will likely occur later this afternoon…will be a strong seabreeze boundary racing northward from the coast as a warm front. Higher surface dew-points will surge north basically covering the entire area by around sunset tonight. For areas that encounter this airmass change of higher dew-points at the time of peak afternoon heating.
Going into this weekend, this airmass change of higher dew-point air at the surface will drag forecast convective temperatures down during peak afternoon mixing on Saturday, leading to much better chances of isolated to scattered showers/storms. Generally speaking, we return to a normal summertime pattern beginning the day on Saturday, along with afternoon highs ranging in the mid-90s. With the increase of surface moisture and slight nudge up in afternoon highs, heat indices will range in the 100-105 degree range, so we are not anticipating any excessive heat issues at this time.
