After our week break, we are heading to Saudi Arabia where the weather will be beautiful. This brand new track will present its own challenges, so a clear weather report is just what these teams wanted to see. A high pressure to the east will keep the pressure gradient tightened and moisture low with light to gusty winds coming off of the Red Sea. There are no chances of rain with hardly any cloud coverage as well which will have track temperatures  well above the air temperature. 

I expect these conditions to remain constant as we get closer to race day, but I will keep monitoring this and update you all with any changes. A metric graphic is displayed below...

Harris is on vacation this weekend, so I'm taking over the updates for the Qatar GP. Not much change was needed from his original forecast. The weather continues to look great for the inaugural Qatar Grand Prix. Temperatures will be warm but not brutally hot, thanks to an easterly wind off the Persian Gulf. Sunday will have slightly higher wind speeds than Saturday, from the southeast at 10 to 15 mph through the day. A Celsius graphic is below.

As we head across the pond to Qatar, the weather conditions are expected to be perfect. Hardly any moisture will be over the area with clear skies. A Low pressure system to the west of the site will cause a wind shift from northwesterly to southeasterly as the weekend progresses. Wind speeds will be light to occasionally moderate as a bit of sea breeze gustiness could affect the drivers in the afternoon hours. 

Overall quite favorable conditions for these teams' which they hope for as we are rounding out this season. A metric graphic is displayed below...

A cold front will move through Road Atlanta early Saturday morning. No rain is expected with the front, and the air mass over Georgia is very dry. The main impact of the front will be chilly temperatures through the race. There will be abundant sunshine, but high temperatures will only reach the mid 50s. By the end of the race, we could see temperatures dropping into the 30s. For those who are camping at the track, low temperatures Saturday night will be in the lower 30s, so you could wake up to frosty conditions Sunday morning. Stay warm!

The forecast has not changed much with the same southeasterly flow and high moisture content expected. Moderate temperatures will be present with mostly cloudy skies and light to moderate winds. Higher pressures remain to the southeast of the site keeping the pressure gradient tightened over the site. This will keep wind speeds consistent throughout the weekend and will keep the chance of showers present as well. Chances are low as these potential showers will likely be short lived. I will keep an eye on it and update you all with any changes. A metric graphic is displayed below...

Good news on the forecast for Petit Le Mans with today's update - the best chance of rain has shifted earlier, mainly Thursday night, which will have less potential impacts on the racing. 

Wednesday continues to look like a beautiful day, with warm temperatures in the lower and mid 70s under mostly sunny skies.

On Thursday, clouds will increase, along with the chance of rain. I expect to see on/off light showers at times throughout the daytime hours, but they might be more numerous in the afternoon. While an isolated thunderstorm cannot be ruled out, I think the chance of one at the track is low. On Thursday night, heavier showers will be possible along a cold front, which is most likely to pass through the area between midnight and 4 am. The chance of rain will likely end once the front passes. However, The models still have some slight timing differences, and so I still kept a slight chance of showers in for early Friday morning (around or before sunrise). The rest of Friday should be very nice, with clouds clearing out and high temperatures in the mid 60s. 

Saturday will be noticeably colder as a second cold front will bring a surge of cold air from the northwest. Highs will only reach into the 50s, and winds will be brisk, from the northwest at 10 to 20 mph. If you're at the race on Saturday, don't forget to bring a coat!

As we head down to the Brazilian Grand Prix, we can expect cloudy skies with mild temps as southeasterly winds will be keeping moisture levels high. A gradually tightening high pressure gradient will be increasing wind speeds slightly over the weekend with occasional light showers around the area. This will make the teams' rain strategy a game time decision as these storms will be short-lived and spotty. 

The conditions are likely to change a bit throughout this week, mostly with the timing of the possible showers. I will continue to monitor this and keep you all updated with coming changes. A metric graphic is displayed below...

Rain could be a factor at times at Road Atlanta on Thursday and Friday as a cold front moves through the region. There is uncertainty about the timing, which makes for uncertain impacts on the racing. But I think the chance of seeing rain tires on the cars at some point is pretty good. 

Wednesday will be a beautiful day with southerly winds bringing mild temperatures in the lower 70s, and mostly sunny skies.

Scattered rain showers are possible in the area on Thursday, and timing is too uncertain at this time to pinpoint a favored time for showers. But it does appear likely that they will remain light and brief, so I don't expect much impact. 

Rain showers should be more numerous on Friday as a cold front gets close to Road Atlanta. With rain amounts on Friday expected to be light, I think the racing will be able to continue with wet tires. Timing is also uncertain as models are showing different timing of the frontal passage. The earliest timing pushes it through in the morning, with the latest timing pushing it through Saturday morning. So quite a big difference. The most likely solution is that it will exit by the start of the race on Saturday, and colder temperatures will follow the front. The main event should be dry and mostly sunny, and breezy with a northwest wind at 10 to 20 mph.

I will continue to monitor and update as needed through the week.
