NASCAR Homestead-Miami weather forecast: Mostly dry, chance of showers early in the weekend. The 2012 NASCAR season comes to an end this weekend at Homestead-Miami Speedway. I expect most of the time to be dry this weekend, but a chance of a passing shower later this afternoon and on Saturday cannot be ruled out. This afternoon there is a broken line of showers to the east of Homestead-Miami Speedway just off shore, slowly drifting west-southwest. Many of these are falling apart as they reach land but a few could hold together and reach the track. These showers are strong enough that they could cancel any scheduled practice or qualifying later today. See below for full schedule and forecast. For Saturday, the same scenario is possible, with a mix of sun and clouds and a chance of a passing shower. Most of the time will be dry but a few showers could form along a stalled boundary offshore and drift inland over the track causing possible problems. Sunday's Sprint Cup finale looks mostly dry and mostly sunny. There's still some question on whether or not isolated showers could form late in the day, but for now I'm going to leave them out. I'll wait on more data to come in and could see showers mentioned in tomorrow's weather forecast. Temperatures for today through Sunday are nice and warm with afternoon highs in the upper 70s to near 80. Please follow me on Twitter @NASCAR_WXMAN and like me on Facebook for the
