A beautiful weekend is on tap for IMSA and INDYCAR at Long Beach. The main impact will be morning fog, as a southerly wind from the ocean will bring the marine layer inland each morning. With daytime heating, the fog will dissipate, likely by 10 AM, but it could impact some of the morning sessions. Temperatures will be pleasant, if a bit cool, reaching the upper 60s to lower 70s each afternoon.

The weather looks great for this year's edition of the 12 Hours of Sebring, with abundant sunshine, dry conditions, and warm temperatures. A large high pressure system off the east coast of Florida will dominate the weather pattern through the end of the week, producing a southerly flow that will warm temperatures well into the 80s, and around 90 by Saturday.

The weather continues to look great for the Rolex 24 this weekend. The first two day at the Speedway have been wet and windy, but conditions will be better for the rest of the event as high pressure builds over the area. Dry conditions are forecast each day, with breezy conditions on Friday. Winds will be lighter on Saturday and Sunday. Nighttime temperatures will be cold, but there will be plenty of sunshine during the day, with highs warming into the 60s for the race. 

Saturday evening's sunset time is 5:56 PM, and the sunrise Sunday morning is at 7:15 AM.

The weather will be wet to start the on-track activities at the Rolex 24, but conditions will improve for the weekend.

A cold front will push through Florida from north to south on Tuesday night and Wednesday. Showers with this front will affect Daytona mainly on Wednesday morning. Scattered showers may linger into the afternoon, and it will be quite breezy all day with gusts reaching around 30 mph. The front will be south of the area by Wednesday night, but it will make a northward push again on Thursday. This will bring another chance of showers, although the coverage is expected to be more scattered, and the timing is more likely to be in the afternoon. 

A large upper level trough will help to push the front to the east on Thursday night, bringing drier but colder air on Friday. Morning lows Friday and Saturday mornings will be in the 30s, so bundle up if you're camping at the track or arriving early. The race conditions look great, with sunny skies at the start and dry conditions expected for the entire 24 hours. Clouds will be increasing on Sunday, and temperatures will be trending warmer with highs in the mid 60s by the end of the race.

Confidence is increasing that rain will impact the Roar on Sunday, and running will likely be limited due to the rain.

Friday continues to look like nice weather, although temperatures will be chilly to start the day. On Saturday, winds will shift to the south as high pressure moves off the east coast of Florida. This will bring warmer temperatures, but also increasing clouds. Some models are showing light rain arriving in the afternoon, while others keep the day dry. I added a mention of late day sprinkles to account for this. 

A front slowly approaches Daytona from the north on Sunday. Rain will begin in earnest Saturday night and continue into Sunday. During the day, about a half inch of rain will be possible. I expect that the timing of this rain will be mostly in the morning, with light rain persisting into the afternoon. This will likely mean that running will be limited on Sunday as rain will likely be moderate at times.

It's time for racing in 2025! IMSA's Roar Before The Rolex 24 gets underway this weekend at Daytona, and the weather looks to be a mix of good and not-so-good. High pressure will be off the west coast of Florida on Friday, providing a north wind that will keep temperatures on the cool side. This high will shift east and be off the east coast of Florida on Saturday, turning winds to south and warming temperatures into the mid 70s. A cold front will approach the area from the northwest on Sunday, spreading showers into the area during the day. Details on timing and rain amounts are too uncertain to pin down this far out, but right now the chance of seeing rain on Sunday is about 50/50. Check back later in the week for more details.

Ideal weather conditions can be expected at Road Atlanta this weekend for Petit Le Mans. A front is currently located well south of the area, near the Georgia/Florida border. This will act like a barrier to Hurricane Milton, which will track across central Florida, and stay well away from northern Georgia. High pressure along the East Coast will continue to build over northern Georgia through the rest of the week, and provide dry conditions with pleasant temperatures. It will get a little chilly at night if you're camping at the track, especially Saturday morning when lows will drop into the 40s. Lows on Saturday night will be around 50 degrees.
