To see realtime and recent temp, rain, cloud cover and wind historical data look no further than the Black Rock Station and for forecasts, the closest to best is the Nat'l Weather Service's Gerlach report.
Don't be skimping on the stakes and ropes and use them with extreme prejudice upon arrival. Overnight wind speeds surpassed 50mph the last two nights, with continued whip-ups above 40mph for extended periods. Daytime wind speed is averaging in the teens and due to all the vehicle movement, dust laden winds will blow throughout the event.
