No surprises are in store for the weather during the 24 Hours of Daytona. Dry weather is expected through the race, with mostly sunny skies today followed by clouds generally increasing through tonight and tomorrow morning. There is a chance of rain that will arrive Sunday night, but it will not arrive until long after the end of the race. By Doug Schneider The weather for the Rolex 24 continues to look great with today's forecast update.
Today, a few light showers are possible as a cold front approaches the area. Temperatures will be quite warm, with a high near 80 degrees. The cold front will move through tonight. Thursday will be much cooler behind the cold front, and it will be breezy as well with gusts up to 25 mph at times. The remainder of the event will see sunny skies and a gradual warming trend as winds shift to a southerly direction by Sunday. There will be a low chance of light showers arriving Sunday night. This timing has been consistent for the past few days, but I will keep an eye on it in case it moves up into Sunday afternoon and potentially affect the end of the race. By Doug Schneider Good news - the weather looks great for the 24 Hours of Daytona this year. After a cold front moves through on Wednesday night, large area of high pressure will be moving across the Southeast Thursday through Sunday, keeping dry weather and mostly sunny skies in the forecast.
The only chance I rain that I can see at this moment is on Wednesday, and even that looks very marginal. A cold front will be approaching during the day, and crossing Daytona at night, so what little rain may come with this front could be mostly on Wednesday night. There will be a couple practice sessions that day, but I don't expect that there will be enough rain to have any impact - just a few sprinkles or light showers. Behind the cold front on Thursday, the weather will get quite a bit colder, with breezy and gusty winds. Gusts of 25 to 30 mph can be expected at times. North winds at 10-15 mph will continue into Friday, which will keep temperatures cool, but at least it will be sunny all day. On Saturday, high pressure will move off the east coast, shifting winds to a more southerly direction, which will help warm temperatures into the 70s for the start of the race. An upper level low pressure trough will approach on Sunday, but any rain with it is expected to hold off until Monday. It will result in some increasing clouds on Sunday afternoon, but temperatures should still be able to rise into the mid 70s by the end of the race. I plan to have the next forecast update posted on Wednesday, unless there's a major change in the forecast. By Doug Schneider Beautiful California weather can be expected this weekend as IMSA heads to WeatherTech Raceway Laguna Seca.
A large high pressure ridge will be over the west coast for the second half of this week. Through the weekend, this ridge will shift to the east, and a low pressure trough in the upper levels will approach from the west. The main affect of this will be temperatures that will trend warmer each day of the event, and a slight increase in high clouds on Sunday. Morning fog is often an issue at Laguna Seca, and while it can't be ruled out, it is too far out in the forecast to mention it as a problem at this time. Forecasting fog is difficult even a few hours in advance, so I'm not going to try to do it 4 to 6 days in advance. We'll see how that develops in later forecast updates. By: Stephen McCoy The general weather pattern of the weekend remains similar to the initial forecast from Monday. High pressure will be present over the region through Thursday before a cold front stretching through much of the east coast move through on Friday. High temperatures ahead of the front will be mostly near-normal in the low to mid 70's; behind the front, Saturday's high temperatures will be in the mid 60's.
Winds on Thursday will start from the east, but will shift towards the south as the day progresses, with mostly cloudy conditions expected in the mid levels during the morning to mid-afternoon, with partly cloudy skies for the later afternoon. A slight chance for isolated showers is possible around mid-day as the front begins its approach; rainfall would likely be in the form of light drizzle. Conditions for Friday will begin as mostly to fully clear before partly to mostly cloudy skies move in during the afternoon. Winds will largely be from the north to northwest during the day; a similar chance for precipitation to Thursday is expected. The northwesterly winds on Friday will cool temperatures on Saturday to a low in the upper 40's. High pressure building in behind the front will cause winds to shift to the east to northeast, keeping temperatures relatively cool into the day. Zonal upper level flow will cause clear skies for the majority of the day, though some light cloud cover in the low levels may move in during the afternoon to evening. |
