The models agree in the general pattern of a low pressure system tracking east across the Great Lakes region this weekend. This system will drag a cold front across Ohio at some point during the race event, possibly as early as Saturday afternoon or as late as Sunday morning. As of today, the most likely timing for the front to pass through is Saturday night. Ahead of the front on Saturday, there will be a south wind at 10 to 15 mph that will bring some warm, moist air for scattered showers and thunderstorms to form in the afternoon. Again, the timing of the front will impact how numerous these storms will be during the day. I have the chance of rain affecting the on track action at 50%.
I have a slight chance of showers in the forecast for Sunday to account for the possibility of a later frontal passage. If the earlier timing turns out to be correct, Sunday will be dry as high pressure builds over the area from the northwest. It will also feel less humid and slightly cooler behind the front. If the later timing of the front pans out, then the chance of showers on Sunday will increase.
Check back for updates through the week.
