Official Forecast For Saturday’s Iron Horse Ride

For those of you not attending or participating in Saturday’s big event, I will be posting a “regular” weather update this afternoon.

Here is the updated forecast for Saturday. The biggest changes are slight variations in wind directions and wind speeds with slightly warmer temperatures. Winds will be slightly higher in the afternoon, but the weather models are not showing the gusts that were there earlier. The other change is a 20% chance of showers and thunderstorms after 12 pm. The model consensus is showing .01″ of precipitation. This indicates to me that if showers do develop, they may not make it to the surface before evaporating. That being said, this is something I am watching very closely.

I have edited the summary and forecast grids with the changes.

The big day for the IHBC is going to be the nicest day of the week and one of the nicest days this spring! At the start time in Durango, the temperatures will be in the mid to upper 40s. Winds for the event will start out of the northeast. But will transition by mid-morning to the south and southwest. Between noon and 3 pm winds will be between 12 and 18 mph. The high temperature in Durango on Saturday will peak near the mid-80s with high temperatures in Silverton around 70 degrees. Skies will start clear and end up partly cloudy towards the end of the day. At this point, there is a 20% chance of very light precipitation between noon and 4 pm on the passes and in Silverton.
