Miami Valley , Whitewater Valley, and the I-71 corridor of Ohio/Indiana:
A cold front has still yet to come through until 9pm. This keeps the chance of a severe storm around with a line that will move SE across the region this evening. This line will mainly be damaging winds and hail. However with plenty of shear an isolated tornado cannot be ruled out still, hence the tornado watch until 9pm. Today's low level cloud cover has come from fast SW winds blowing whats called scud and other types of low clouds NE in to our region from storms to our South. This has kept temps down keeping the energy for the atmosphere to work with down as well. There have been plenty of strong storms South and North due to areas of sunshine, but here in SW and Western Ohio storms have been little to none due to this low cloud deck.
Behind this front tomorrow we can expect very cool air to move in from Canada with an upper level low that will cause scattered showers throughout the afternoon. Each day this week will be cool but a slight increase in humidity by the end of the week will mean a chance of a shower each afternoon and evening as several weak upper lows move through the Great Lakes.
