Residents with family or plans in Ohio should pay attention to the latest weather developments, as the National Weather Service (NWS) has forecasted a pattern of isolated to scattered showers and thunderstorms through the weekend, with a particular emphasis on the afternoons and evenings, and temperatures set to be near or above normal for the week. According to an update from the NWS office, dry conditions may make a brief return next Monday and Tuesday, providing a short respite from the rain.
For those flying out or driving around regions such as Columbus, Cincinnati, Wilmington, and beyond, there's a bit of a mixed bag on the weather front, early morning fog is expected to clear up by 13z – that's just in time for some diurnally-driven cloud formation which might play spoilsport by triggering a spotty showers and thunderstorms especially near the I-71 and I-70 corridors. However, heavy rain and the potential for localized flooding seem like a risk in certain corridors like Montgomery/Miami through Hardin/Union/Delaware counties in Ohio.
The forecast from the NWS indicates that today's highs are expected to reach the mid-80s, which is quite seasonable for this time of year, after that patchy fog they mentioned clears out air traffic and transport hubs might see conditions temporarily return to VFR, but with the possibility of episodic thunderstorms through the weekend, travel may be met with intermittent delays or issues.
For the longer term outlook, a weak ridge building in Friday night may signal the end of afternoon or evening thunderstorms fading into the overnight hours but another shortwave from the central Plains, merging with a larger trough dipping into the Great Lakes on Saturday, is expected to continue disrupting the weather pattern with warm southwesterly flows bringing hot conditions and heat indices near the hundred-degree mark before moisture associated thunderstorm chances reassert themselves through mid-week.
As we move into Sunday, the NWS notes that the trough and associated cold front will likely bring another round of thunderstorms, particularly along and southeast of the I-71 corridor affecting both central and southern Ohio and northern Kentucky, areas which also stand a chance of experiencing isolated severe weather episodes. Following that, there may be a small window when the thunderstorm activity subsides on Monday and Tuesday before potentially picking back up by Wednesday.
