A frontal boundary is driving scattered showers and thunderstorms across much of the central and eastern United States through the weekend, while high pressure maintains hot, mostly dry conditions from the Intermountain West into the central Plains. NOAA's 6–10 day outlook for August 9–13 indicates near- to above-normal rainfall probabilities over most of the contiguous U.S., with the highest chances tied to this frontal activity, contrasted by drier-than-normal conditions from eastern Texas into the lower Mississippi Valley. Short-range models show 20–40% precipitation probabilities in the Midwest and Northeast on the 9th, with lower odds farther west; these can shift with overnight model runs from the National Weather Service. Traders should monitor updated NWS local forecasts and quantitative precipitation outlooks for resolution thresholds.
