Some Mesonet rain gauges in the state may be impacted by frozen precipitation. This precipitation will be recorded on our maps when temperatures rise above freezing and the snow and ice melt in the gauges.

During precipitation events involving ice, sleet, or snow, the rain gauges used by the Oklahoma Mesonet may freeze over and record no rainfall. Once air temperatures raise enough to allow thawing, accumulated frozen precipitation in the gauge will melt (sometimes over several days) and be recorded.
