Yes the humidity is also fairly high, mid-60s dewpoint.
No one is talking about this, but there is a chance of thunderstorms near Waco sometime on Saturday afternoon, the wind is supposed to shift from south to northeast after the storms go through, temperatures drop from near 100 to the low 90s. The timing of this is hard to say 3 days out, so there’s an outside chance it blows through late morning, pre kickoff or delaying kickoff due to lightning risk. Current official forecast for the most likely time for this is in the window 1-4 pm, which could be as early as the 3rd Quarter or as late as post-game.
