High Based Convection Produces evening downburst winds Star Valley Ranch

Strong daytime heating evidence by the temperature rising from an early morning low of 38 at Etna Elementary to a high of 90, produced very high based cumulonimbus which tracked across Star Valley Ranch during the late afternoon/evening. While only sprinkles actually reached the ground, the evaporation from the precipitation falling from the high based clouds, did produce down burst winds. The strongest reported gust was 45 mph at Star Valley Ranch at 6:13 pm.  The following cam video taken from Bedford looking north across Star Valley Ranch clearly shows the cumulonimbus clouds and the evaporating precipitation.
