A large high pressure system is expected to be the main weather feature throughout the 6 Hours of Shanghai weekend, which should provide nice weather conditions each day. The high pressure center starts out to the northwest of Shanghai on Friday, and as it builds in behind an exiting front, it will be breezy, with a north wind at 10 to 20 mph. The high shifts east through the weekend, and as it moves toward the Korean Peninsula and Japan, it will turn winds to the east. This will bring some moisture off the ocean - enough to increase cloud cover on Saturday and Sunday, but likely not enough to produce rain as the moisture should be shallow and confined to the low levels of the atmosphere. However, I'll be keeping an eye on this to see if it changes as we get closer to the weekend.
