After a taste of fall-like weather this past week, a sweeping cold front will bring another reinforcing shot of cooler than normal air to much of the Great Lakes, Ohio Valley, Northeast, and Mid-Atlantic the next few days. High temperatures will mostly top out in the 60s and 70s, with overnight lows dipping into the 40s and 50s. Some of the typically colder spots may even drop into the 30s. In addition to cool temperatures, the front will also likely spark a few scattered showers and thunderstorms across parts of the Northeast through the holiday weekend. Otherwise, high pressure builds into the Great Lakes and Ohio Valley in the wake of the front, delivering very pleasant weather to round out the month of August. While much of the Lower 48 are experiencing temperatures that are more common in September and October, summer-like warmth continues to hold strong across parts of South Texas, the Desert Southwest, and the Pacific Northwest. Temperatures in these hot spots will soar well into the 90s, with some places climbing into the triple digits. The hottest temperatures will be found in the lower desert valleys of southern California, southern Nevada, and southwest Arizona where highs will near 110 degrees. To beat the heat this Labor Day weekend, remember to stay hydrated, take frequent breaks, and seek shade and air conditioning when possible. Wet and stormy weather is in store across much of the Plains, Gulf Coast, Southeast, and Florida through the weekend as several slow-moving frontal systems provide the focus for daily shower and thunderstorm activity. The slow motion of these systems combined with well above normal moisture will set the stage for frequent rounds of downpours and the possibility of localized to scattered instances of flash flooding. Multiple Slight Risks of excessive rainfall (level 2/4) have been outlined in these areas, highlighting the potential flash flood danger to Labor Day weekend travelers. If traveling this weekend, make a plan before venturing out, and be sure to be aware of alternate routes in case you encounter flooded roadways. Remember, Turn Around, Don`t Drown!
