Ohioans can expect a marked shift in weather today, according to the latest from the National Weather Service in Wilmington. The NWS reports that as high-pressure swings east of the Ohio Valley, the region will experience warmer temperatures, increased humidity, and a raised possibility of showers and thunderstorms heading into the weekend.
The short-term forecast suggests that while today will remain predominantly sunny, clouds will gather later in the afternoon. Those residing north of I-70 might notice the shift, with the forecast highlighting the increasing southerly winds that will usher in warmth and moisture. These conditions set the stage for a balmy evening, where temperatures are anticipated to stay mild, thanks to "increasing cloud cover and veering southerly winds," according to a statement obtained by the National Weather Service.
Thunderstorm activity could ramp up significantly by the end of the week. The NWS points to the elevated risk of showers and storms late Thursday night into Friday morning as a warm front lifts through the Ohio Valley. Though the initial wave of storms accompanying the warm front isn't expected to pose severe weather threats, the NWS advises that the "elevated MUCAPE and higher PWATs" signal periods of heavy rainfall may be on the horizon.
By Friday afternoon, storms that do manifest carry a potential risk of developing into severe weather, mainly due to high DCAPE and increasing shear, which could translate to hazardous wind conditions. However, it's not all doom and gloom. Saturday is predicted to cool down following a cold front passage. Temperatures, notably, are poised to decline across the board, with highs only topping out in the upper 70s to near 80 entering the weekend, the NWS provided in their long-term outlook.
Aviation interests throughout the Ohio Valley will also want to stay alert. The VFR conditions prevalent for most of the TAF period will be disrupted post 0600z Friday, as chances for showers/storms and MVFR/IFR ceilings surge with the warm front's progression. Pilots operating in the region should anticipate potential impediments to air travel and plan accordingly.
