Mix tonight, Severe on Tuesday?

We will be warm on Tuesday. All of the state will see at least 50 on Tuesday, and the southern portions of the state will see 60-65. This, along with a cold front coming through will cause some showers and thunderstorms. There is definetly a severe weather threat with these storms late Tuesday into Tuesday night, mainly for the southern half of Ohio. Here's why: A low riding a long the front will bring in more energy, and as this happens the warm front, dividing the warm air from the tropical air will be right over the middle of Ohio. I think south of the warm front, there will be enough instability for a severe weather outbreak. North of the warm front, I think there could be some thunder and heavy rain, but the severe weather threat looks to be much lower. I will have much more on this potential severe weather outbreak tomorrow and Tuesday.

Tonight, as precipitation moves in along a warm front, the temperatures aloft will be above freezing, but it looks like surface temperatures, mainly in extreme NE Ohio could be just bellow freezing, so areas from Cleveland-Akron-Youngstown and northeast could see at least some ice at the onset of precip, and areas that are normally a little coolder may see 2-4 hours of ice to start the precip. With temperatures being marganal, most roads should be fine, but bridges and overpasses and un-treated surfaces my recieve a glaze of ice late tonight. Tomorrow any ice will quickly change to rain with highs of 45 to 50.
