Considering the delay in the AWOS reporting, it may also be helpful to proactively use the radio to ask anyone on the ground for the current winds (e.g. Microbursts are not the only source of severe wind-shear close to the ground. Sudden and very powerful surface winds can have various other causes. the local FBO).

Moderate wind shear in some areas could make some thermals somewhat difficult to work but that, too, is typical. Between 5:10 and 5:34 PM, Rifle’s AWOS system reported light winds out of the west in the range of 4 to 9 kts (see chart below) with no wind gusts. 65 kts IAS given the high density altitude.

Weather Go-arounds due to weather occur due to wind shear caused by gusting winds or microbursts. When an aircraft encounters horizontal wind shear, it could be blown off centerline. Similarly, if an aircraft encounters vertical wind shear, it reduces or increases the sink rate.
