I know everyone is hoping for great weather at Daytona this weekend, and the forecast has some good aspects (warm temperatures!), but some bad as well (rain likely on Sunday).
A high pressure system will be moving across the Southeast states through Wednesday and Thursday, then move off the East coast on Friday. As this happens, winds will shift from a northeasterly direction on Thursday to an easterly direction on Friday, then southeasterly on Saturday and Sunday. The result of this will be a warming trend each day, but also increasing clouds each day as moisture starts to increase.
On Saturday, a low pressure system will be moving across the central United States, with a trailing cold front moving across the Gulf Coast region. The front will move across the Florida Panhandle on Saturday night, then into the Florida Peninsula on Sunday. There will be showers and possibly a few thunderstorms ahead of the cold front, but the big question is the timing. And for the race, timing is everything. On the bright side, and nice southerly wind will provide comfortable temperatures in the lower 70s on Saturday and Sunday, so there won’t be a cold rain like last year.
We are still too far away from Sunday to pin down the timing with any certainty, but I think the most likely scenario right now is that there may be some light rain showers Saturday night and Sunday morning, with an increasing chance of rain through the day. The potential for heavier showers and possible thunderstorms will come in the afternoon. The end of the race is at 2:40 pm EST, and I cannot say with any confidence whether the heavier rain will come before or after the end of the race. We’ll just have to wait and see how things develop through the week before I can give more detail on the timing.
