Miami Valley , Whitewater Valley, and the I-71 corridor of Ohio/Indiana:
A winter storm will cut across the Southern Ohio Valley tonight producing 3 to 6 inches of wet snow through Southern Ohio. Our region will be just on the North side of this storm meaning areas along I-71 may see periods of snow with an inch or less possible. While places SE especially along US 22 may see up to 2 inches of snow by dawn. Tomorrow brief high pressure will build in allowing for some pm sun but cold to lock in. This will set the stage for the next possible winter storm that will track further North. Current forecast tracks are for the low to track just West of the Appalachian mountains weakening as it goes into West Virginia and then transferring its energy to a low off the coast of Virginia. Initially some warm aloft (Over our heads) will accompany the storm Tuesday evening allowing for a rain/sleet/freezing rain mix to occur but as the low weakens colder air will filter in aloft changing precipitation to snow late Tuesday night and Wednesday am. This would put moderate accumulations of snow and some ice accumulations across the I-71 corridor and mainly rain SE of the I-71 corridor. Areas well NW of the I-71 corridor may stay all snow with significant accumulations likely. Stay tuned as there are several more model runs to analyze as this is a developing winter storm and has the potential to shift in track and bring significant winter weather to the area.
Behind this storm very cold air will return to the region with another brief high pressure building in. Another low pressure may effect the region over the weekend.
