Early this morning, a cold front is crossing Belgium. As the front moves through, colder air at the surface will move in, dropping temperatures into the mid 30s. This will result in snow falling at Spa-Francorchamps this morning. Since temperatures are expected to hover just above freezing, it will be difficult for any snow to accumulate on the ground. At best, there may be a light dusting of snow on the grass around sunrise. The snow is expected to end sometime between 9 am and 11 am as some drier air aloft moves in behind the front. There will likely be a lull in any precipitation for a few hours as the pre-race ceremonies take place, and I expect that the start of the race will be dry, although some sprinkles will be possible at times. However, an upper level trough will be moving over the area in the afternoon, which will bring a return of some rain. I expect that this rain will remain quite light, with only a few hundredths of an inch or a couple millimeters expected to fall through the day. While the track will be wet and rain tires will be needed, I think the race should be able to run without significant impacts or delays - thus, I have put in green flags for the Impact. Toward the end of the race, rain will likely taper off or come to an end. Temperatures will be cold all day, never rising above the lower to mid 40s F or single digits C.
