Yesterday we had a short, sudden wind event at our station in the Denver Colorado area. The wind was strong enough that it blew over the barbecue grill on the patio.
Just before the event the wind speed was low, about one mile per hour with gusts of about two mph. The Wind Speed graph is calibrated in five minute intervals. The recorded wind gusts were 2 mph at 2:30 pm, 5 mph at 2:35 and then peaked at 29 mph at 2:40. I suspect that there had to be something higher to knock over the grill.
What is the likely cause of this event? Is there a way to know the size of this event? For example, would the event show up on weather radar? Or, is there a way to determine if other private weather stations experienced this weather event?
Does WeatherFlow record data more frequently than every five minutes? If so, is it saved in a location that I can access? Are there any organizations or individuals that collect weather data for events like this?
