Residents in Columbus, Cincinnati, Wilmington, and the wider Ohio region can expect a continuation of unstable weather as an upper-level low pressure system moves through the area, bringing with it occasional showers and storms. According to the Area Forecast Discussion from the National Weather Service Wilmington, OH, this low pressure is currently centered over western Tennessee and will be tracking northeast into the afternoon.
Weather experts forecast warmer conditions towards the end of the week, after the pesky low makes its exit. However, the reprieve may be brief as there's another chance for showers and thunderstorms beginning Thursday night. Today's maximum temperatures are expected to hover in the lower to mid 70s, but the rain and overcast skies could mean that some areas might register a few degrees cooler, according to the National Weather Service in Wilmington, Ohio.
The forecast indicates a drier overnight period into Wednesday, with some scattered showers still possible under the upper low. Wednesday's highs should be a tad warmer, hitting the mid-70s range. As for any hazardous weather concerns, the severe threat is notably low, though the National Weather Service in its discussion says areas that experience repeated storms or have storms that back-build could face isolated flooding.
A shift in the surface pressure pattern is expected Wednesday night as remnants of the surface low-pressure system fade away. The forecast calls for light southeasterly flow into Thursday morning with lows in the lower to upper 50s in the east. However, as is often the case with weather forecasts, uncertainty remains, particularly around the severe potential of the incoming storms on Thursday and Friday. "The farther east, the more challenging it will be for moisture to return northward. The shortwave trough will still provide the potential for showers and thunderstorms, but the potential for widespread severe impacts would be lower," explained McGinnis from the National Weather Service.
For those making weekend plans, the outlook hints at a trend towards more seasonable temperatures by Sunday and Monday as the system progresses eastward across the Great Lakes, with a lower chance of showers and thunderstorms focused south and east. But don't put your umbrellas away just yet, as the region prepares for the next weather system building up for the following Tuesday.
