Residents of Columbus, Cincinnati, Wilmington, and surrounding areas can expect a wet weekend peppered with thunderstorms as a low-pressure system moves through the Great Lakes region. The National Weather Service reports that while storms will be the theme through Sunday, a shift towards drier conditions is anticipated as we head into the work week.
Early risers on Saturday may have noticed a weakening band of showers and a few storms. "A less unstable environment" is the reason behind the dissipation, leading to expectations of a weakening trend, according to forecast discussion by NWS. Later in the day, however, things might pick up again. The area is set to destabilize Saturday afternoon into the evening, setting the stage for potentially severe thunderstorms. The primary concern is along and south of the Ohio River, "where CAMs are showing the best updraft helicities in the 21Z-00Z time frame."
On Sunday, the upper-level trough axis will slow eastward across our region, leading to widespread showers and potential thunderstorms again as the day heats up. Despite the chance for more storms, temperatures are projected to cool off, with highs only reaching the upper 70s to lower 80s.
Moving into the next week, temps are expected to take on a more autumnal feel. "Temps again 5-8 degrees below normal through Wednesday," describes the extended forecast of NWS. Daytime highs hovering around 75 degrees will be complemented by cooler nights, dropping as low as the lower 50s. An uptick is suggested for the end of the week, with temperatures approaching the mid-80s by Friday. While Monday evening could see lingering showers, a dry spell is anticipated to dominate the region from Tuesday onwards.
Pilots may encounter some difficulties during air travel due to the weather. A line of showers and thunderstorms could disrupt flights, particularly around KDAY during the early hours. However, conditions should improve as we approach Monday morning, with clarity ascendant as MVFR to IFR clouds clear.
