GFS Model valid from 7:00 am Friday to 7:00 pm Sunday (animation from TropicalTidbits.com).
As you can see by the above animation, rain still looks to be possible at times over Circuit Of The Americas throughout the weekend. There will be a weakening system moving through the area that will still have enough kick to fire off some scattered showers and thunderstorms during the a time frame that stretches from Friday evening through all of Saturday and Sunday.
At this point, all of the on-track activity for Friday will be dry as those shower chances do not ramp up until after 6:00 pm. Skies will be mostly sunny to start the day, but clouds will be moving in throughout the morning and afternoon hours. Morning temperatures will start off right around 50 degrees at 8:00 am and rise into the lower 70s for the daytime high. Winds will be out of the southeast at 1-5 to start and increasing to 5-10 by afternoon.
Really, there is no change to the forecast for Saturday... We'll have cloudy skies throughout the day with the possibility of showers and thunderstorms moving across the track at any time. Morning temperatures will start off in the lower 50s and only make it into the upper 60s by the afternoon. Winds will be out of the southeast at 6-12 MPH. The chance of rain for Circuit Of The Americas at this point is at 50%. Rainfall amounts throughout the day should end up around 0.25 inches.
With the possibility of lightning, you will have to be weather aware while at the track. If you hear thunder, you are close enough to the parent thunderstorm to be struck by lightning. Find a sturdy building or a hard top vehicle to see shelter until the storm passes. The good news is that there are no strong to severe storms expected, so you don't have to worry about strong winds or tornadoes.
Sunday will be a much warmer day at the track with more clouds than sun, but we will continue to have a very small chance of a passing shower or thunderstorm. The good news is that the model has been trending a little drier on this run so rainfall amounts, if any falls, should be around 0.05 inches... maybe just enough to bring out the rain tires for a stint. We'll start off in the lower 60s at 8:00 am and warm into the mid-70s for the afternoon high. Winds will be out of the south at 6-12 MPH. The chance of rain for Circuit Of The Americas at this point is at 20%.
