The 120-day Rainfall Accumulation map displays accumulated rainfall observed at each Mesonet site in the last 120 days. This map also displays the NWS Arkansas-Red Basin River Forecast Center
's rainfall estimates (in color) across Oklahoma based on radar.
During precipitation events involving ice, hail, 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 and be recorded.
