Residents across Columbus, Cincinnati, Wilmington, and surrounding areas braced for scattered showers and a chance of thunderstorms today, as low pressure made its presence known. According to the National Weather Service, this weather event is due to a low tracking across the area, with a large upper-level low over the Great Lakes influencing cooler and unsettled conditions forecast for Thursday. A glimmer of relief may be in sight by Friday into Saturday as high pressure is expected to usher in some drier spells, but by Saturday night, the rain may return with another low pressure tracking south of the area.
Today's daylight hours will likely see a continuation of the moist narrative, with the potential for increased shower activity this afternoon as the short wave trough approaches. The National Weather Service cautions, "Some marginal instability develops across the east and therefore a brief window exists for thunder." Winds are also set to pick up, with forecasts indicating that gusts could reach from 30-35 mph during peak mixing times due to a tightening pressure gradient on the backside of the surface low pressure. Temperatures, meanwhile, will be on the cooler side under mostly cloudy skies, with forecasts predicting highs ranging from the lower and middle 60s in the west to lower 70s in the east.
The evening leads to a slight decrease in showers as the initial mid-level shortwave pivots eastward but don't plan on stargazing—the cloud cover is here to stay, with overnight lows hovering from the upper 40s to the lower 50s. Thursday's outlook isn't looking much brighter. With additional mid-level energy dropping into the Ohio Valley, the rainfall is set to pick back up. "The threat for showers increases on Thursday as additional mid level energy drops into the Ohio Valley," says the National Weather Service. These overcast skies and persistent showers will ensure that the cool temperatures persist, with Thursday's highs forecast from the mid 50s to the lower 60s.
Looking further ahead, the uncertainty looms larger. The National Weather Service notes that while most precipitation on Friday will be concentrated to the north and east of Central Ohio, rain is anticipated to make a more significant comeback late Saturday night into Sunday morning, thanks to a southeast-dipping shortwave in the central plains and its associated surface low. Waves of showers could then continue to dabble Southern Ohio as we head into the early week, with temperatures expected to remain below the seasonal average due to lower-than-normal atmospheric heights over the Great Lakes and Northeast U.S. As for aviation concerns, pilots should prepare to navigate variable conditions with the forecast pointing towards MVFR ceilings and visibilities into Thursday.
