Let’s head out for a forecast in southwestern Ohio. Shall we?
At 756PM, ET, Dayton was reporting a temperature of 69 degrees with mostly cloudy skies. A sharp, late season trough over the Great Lakess was producing a surface area of low pressure in the lower Ohio Valley, while a leading band of precipitation ran from Virginia southward as a surface low was amplifying instability in that area. Ohio found itself between the two features, but that was not to be a long lived situation.
The broader, upper level low will shift from being centered over Illinois east towards Ohio. As the coastal feature shifts off shore by the early afternoon, the Gulf will be opened and moisture will flood northward. Expect widespread showers across Dayton through most of the afternoon on Wednesday and throughout the day on Thursday as the bloated feature drifts eastward. The best threat for heavy rain, or even an isolated thunderstorm will be late Wednesday when the center of circulation moves overhead. Thursday will see much lighter precipitation with wrap around moisture falling as drizzle.

If this was the winter, Dayton would be in for a great deal of snow, thanks to the slow moving nature of this system, and the temperature change would be much more pronounced. Instead, it’s just going to be gray and dull. Here is the satellite, with clouds across most of the region, but none of those bubbly rain clouds over the Dayton area….for now.
