Unsurprisingly, the forecast for Bahrain later this week has lots of sunshine and warm temperatures - just what you'd expect for an arid desert region. At the surface, high pressure will be centered over the western portion of Saudi Arabia on Thursday, then drift east to the Persian Gulf through Friday and Saturday. In the mid and upper levels, a ridge will be crossing the area. As this ridge moves to the east of Bahrain on Saturday, there may be an increase in high and midlevel clouds behind it, associated with an approaching jet stream and upper trough. But other than some increasing clouds on Saturday, each day will have very similar weather conditions to the day before it, with high temperatures in the mid 80s (upper 20s C) and lows around 70 (around 21 C).

Saturday's weather could be a little wet and definitely windy throughout the day. It will not rain all day as showers moving onshore from the Atlantic will be scattered in nature, but a brief heavy shower could be possible, especially during the late morning through the afternoon hours. The chance of the speedway getting rain will be around 40%. Skies will be mostly cloudy when it's not raining and afternoon highs will be in the lower 70s. Winds will be out of the northeast at 10-20 MPH with gusts up to 28 MPH possible. Rainfall amounts throughout the day should be less than 1/4 inch. Let's cross our fingers that the rain activity stays to the north.
Radar will be up and running on our site throughout the day, so feel free to take a look at any time. If you're using a smartphone to browse the radar, be sure to view as desktop site.

No big changes to the forecast for COTA and the 24H Series races this weekend as the expected weather pattern is still on track. Today has had a good amount of cloud cover that has kept temperatures in the lower to mid 60s. Tomorrow looks like it will be very similar, but it should get a little warmer as winds will be from the southeast instead of the east-northeast. A few breaks in the cloud may allow a little sunshine now and then, but most of the day will be cloudy.
A cold front is still expected to approach the area from the northwest on Sunday. I think most of the shower activity with the front will remain to the west while the race is taking place, but I can't entirely rule out a shower reaching the track. I've left the Impact for the day at None because I think that even if there is a shower (which is only a 20% chance of happening at all), it will be very light and won't influence the race too much. Overall, it will be a nice weekend to get out and watch some awesome race cars.

FRIDAY: A small chance of showers will be possible during the early morning hours, but those shall be well before the cars hit the track. The day will feature more clouds than sun, and winds will be quite gusty at times, especially during the afternoon and early evening hours. Rain chances start to creep back into the forecast by the late evening hours, but the good news is that the main part of the day will be dry. Temperatures will be much cooler than the 82 degrees that was felt at the track on Thursday. Highs will only reach the lower 70s, and winds will be mainly out of the north and north-northeast at 7 to 16 MPH, with gusts up to 25 MPH possible. Grab those jackets and hang on to your hats.
SATURDAY: Mostly cloudy skies and a chance of rain will be possible at Daytona International Speedway throughout the day on Saturday, as the main flow will be blowing onshore from the northeast. Winds will be even higher on Saturday as well, averaging 15-20 MPH, with gusts up to 25 MPH possible. Rainfall amounts will be light if it rains at the track, well less that a 1/4 inch, while the main heavier rain action will stay over the Atlantic well northeast of the track. Highs will be a little warmer, making it into the middle 70s, but those higher winds speeds will make that feel cooler.
I'm more confident in this forecast as the forecast model are coming into a better agreement, but some changes could occur. I'll let you know if they do.

The Creventic 24H Series makes it first ever visit to the United States this weekend at COTA. If you're not familiar with the 24H Series, it features GT3, GT4, and Touring Cars. There will be one race on Saturday from 9 am to 11 pm CST and another on Sunday from 8 am to 6 pm CST.
The weather is expected to cooperate for the majority of the event, and the slight chance of rain on Sunday is not expected to have much impact. By Thursday, a large high pressure system will be centered over the Great Lakes region, dominating the eastern half of the country. This will provide cool and dry conditions for COTA on Thurday and Friday. The high will shift east on Saturday, and the resulting shift of low level winds to the southeast will start to bring a little more moisture off the Gulf of Mexico. Saturday should have warmer temperatures and a little more cloud cover than Friday.
An upper level trough will move into the Plains on Sunday, along with an associated cold front that will move across Texas. This is not a very strong trough or front, and there won't be a lot of moisture for it to work with, but it could produce a few isolated showers around central Texas on Sunday afternoon. I expect that if there are showers around, they will be light. As a result, I don't think that there should be much impact on the racing.
