The low pressure system that brings rain on Thursday will be long gone by Friday, and a weak ridge will build over France and southern England. With a mix of sun and clouds and a westerly wind, temperatures will remain rather cool, with a high near 70 F or low 20s C. Another low pressure system will be tracking between Iceland and Scotland on Saturday, but it should stay far enough north that it will not have much impact on Silverstone. It will be getting breezy with a west wind between 10 and 20 mph with gusts to near 30 mph at times, and the majority of the day will have cloudy conditions. A few drops of rain cannot be ruled out at this time, although it should be so light that I doubt it will have an impact.
Sunday looks rather like Friday, with a weak ridge building over the area while another low pressure system tracks across the northern Atlantic. With a little more sunshine expected, temperatures will reach the mid 70s F or mid 20s C. Some models are hinting at some light rain on Sunday, so I have a few sprinkles mentioned in the forecast, but like Saturday, I don't expect it will have any impact, if it happens at all.
Other than Sunday, the models are in pretty good agreement on this pattern, so my confidence is moderate right now. There may be some tweaks to the forecast as we get closer to the weekend, so check back through the week for the latest forecast and follow our social media streams on the right..
