The weather pattern across eastern China this weekend will be a wet one that will not change much from one day to the next, which means that rain will be a factor in the racing each day.
A front is expected to stall near the Shanghai area on Thursday. Moist air spreading from south to north will run up and over this front. A steady rain will start on Thursday night and continue through Friday. The upper level flow will be from west to east, parallel to the front, so the front will not move much over the weekend. It may drift slightly south, but that should have little impact on the weather, as rain will likely continue into Saturday, and probably into Sunday. One positive aspect of this forecast is that the rain does not appear to be heavy. I expect it will be a steady, persistent light rain that will produce about a quarter to half an inch (6 to 13 mm) each day. As a result, I have a Low impact each day, meaning that rain tires will be needed and there may be some delays to the action, but I do not expect the rain to be heavy enough to cause cancellations.
That's how the forecast looks today, and I plan to have the next update posted on Wednesday, unless there is a big change in the models before then.
