The latest forecast update for PWC weekend at COTA still looks good for a dry event. The general pattern hasn't changed much since the first forecast from Monday, as an area of high pressure will be to the east of Texas through the weekend, providing a southerly flow in the Austin area that will keep temperatures pretty warm. Humidity levels will be increasing each day as the southerly flow persists and spreads moisture northward from the Gulf of Mexico. With this forecast, I have increased the cloud cover a little for Friday through Sunday, as I think each day will start with broken to overcast clouds. The morning clouds should lift and scatter, so there should be some sunshine each afternoon. By Sunday, there may be enough moisture and instability to allow some isolated thunderstorms to develop around central Texas, but the chance of one hitting the track remains low, just 20%.
