Our trip today is taking us to the fine state of Indiana, home state of my alma mater.
At 350PM, ET, Columbus was reporting a temperature of 35 degrees with overcast conditions. The country is in a very chilly pattern which will make things very prone to snow, with the slightest disturbance expected to be able to generate some flurries. A slight perturbation in the jet is going to do just that starting tomorrow over the upper Midwest, despite an overall ridge dominating the country.
The coupling of a pair of jets is the only upper level indication of the system, but some lower level troughing will be tied into a stout surface low over eastern Canada by the time the disturbance drifts towards the Ohio Valley. While a focused stripe is expected further to the northwest when the forcing is almost exclusively influenced by upper air dynamics, the area of snow will become more dispersed as it arrives in Indiana, and moisture will be more diffuse. Total snow in Columbus, which will arrive Saturday will be in the neighborhood of 1-3″, with 3″ being on the very high end of projections.
