WeatherNation’s second forecast will be a hair more challenging than the one in San Diego.
At 756PM, ET, Dayton was reporting moderate snow with a temperature of 24 degrees. Snow was in response to an upper level low that was being reflected at the surface over the mouth of the Mississippi. The upper low was centered over Missouri, and as a result, a great deal of warm air was overriding surface clouds and precipitation, all the way to the upper level warm front, which was near the Ohio River. As a result, an ice storm warning is in effect for Cincinnati, while a winter storm warning was in place for Dayton.
Ice is still a possibility overnight in Dayton on top of the significant snow they will be seeing, which will accumulate in the 6-10″ range. A tendril of warm air at the upper levels will reach into southwestern Ohio shortly after midnight, and a few hours of sleet or freezing rain seem likely. The upper level cold front will usher the warm layer out, and precipitation will continue to fall as snow. The snow will taper through the day, though flurries will remain possible well into the afternoon tomorrow, with clouds finally breaking own late in the day, and much cooler air will take hold. Fortunately, even though Thursday will be colder, it will also be partly cloudy and dry.

And now, we find that WeatherNation’s interface is very confusing. There will be falling temperatures through the day tomorrow (WeatherNation doesn’t have hourly forecasts) and they don’t have an overnight low for the coming night. How messed up is that? This is the best guess I came up with because it was the number pinned to “Night, February 5th” (and it didn’t match the low for what I would think would be Wednesday morning… or Thursday morning. Come to think of it, the top portion of the Dayton WeatherNation page didn’t match the extended forecast at all. So messed up.) Enough about that: Here is a very active radar. The yellow is rain, sleet and ice. Gads.
