I'm not sure you could ask for much better weather for Le Mans week than what I'm expecting this year. There is good model agreement in the general weather pattern, so my confidence in this forecast is fairly high, which means I don't expect bug changes to it as we go through the week.
Practice sessions begin on Wednesday, and that could be the only day that has a chance of rain. There is likely to be a low pressure system moving west to east across southern or central France that day. The position of the low will affect how much, if any, rain falls at the track on Wednesday. It may stay far enough south that no rain will fall, but I think there's enough of a chance to include a 30% probability of rain. It does appear that any rain will be light, so any impact on the practice session should be low. Amounts will likely be less than a tenth of an inch, or less than 2.5 mm.
The rest of the week looks dry as surface high pressure will be centered off the west coast of France, providing a north to northwest flow across the country. Thursday may be a little breezy as the high starts to build in behind the low, with a northwest wind at 10-15 mph (16-24 km/h). Sunny skies with a slight warming trend are expected through the rest of the week and into the weekend. Unless there's a major shift in the pattern shown by the models, it's going to be perfect racing weather through all 24 hours.
