Persistent dryness prevails until midway through the coming week, accompanied by a forecast of elevated heat in Pittsburgh.
The Upper Ohio Valley is bracing for a stretch of hotter weather in the coming days, with temperatures gradually climbing and remaining above normal for the entire forecast period over the next week.
Starting Sunday through next Tuesday, a stretch of low 90s is likely, as each day gets progressively hotter. Highs today will reach the mid to upper 80s for most of the area. The heat indices are expected to be in the mid to upper 90s due to the steamy, humid air.
Scattered showers and thunderstorms may provide some relief amid generally drier soil conditions and sporadic rainfall chances in the Upper Ohio Valley. These storms are anticipated sporadically through the week, mostly tied to cold fronts moving through. For example, better chances for storms are during the morning to midday hours of Wednesday. If the front clears the area, storm chances may cease, but if it gets hung up, low storm chances may persist.
There is uncertainty about whether the front will get hung up just south of the area on Thursday. More clouds may appear by Monday and Tuesday as moisture levels gradually increase.
Regarding cooler air prospects, some short-lived cooler trends may occur if early August’s cooler air lingers a bit longer, but the overall outlook favors warm to hot conditions with only transient cooler periods.
In summary, the Upper Ohio Valley can expect above-normal high temperatures, often upper 80s°F or warmer, with high humidity leading to elevated heat indices. The region is under a high-pressure influence causing warm, occasionally hot conditions. Scattered showers and thunderstorms, mainly mid-week associated with cold fronts, are possible, mostly non-severe but gusty winds possible. Precipitation will be sporadic and occasional, generally drier conditions but some rain expected with frontal passages.
This aligns with the broader August 2025 outlook predicting warmer-than-average temperatures in much of the U.S., with above-normal precipitation favored in the Ohio River Valley but with variable and sporadic storm activity. A strong ridge of high pressure aloft and at the surface is dominating the large-scale pattern.
The weather news for the Upper Ohio Valley this week indicates a rise in temperatures, with the weather forecasting predicting a stretch of hotter weather starting Sunday through next Tuesday, likely reaching the low 90s. Amid this heat, scattered showers and thunderstorms may provide some relief, especially during the morning to midday hours of Wednesday, as these storms are anticipated sporadically throughout the week, tied to cold fronts moving through.
