Wind Chill / Heat Index

Back to Air Temperature Share on Facebook Share Share on Twitter Tweet



Some Mesonet wind sensors in parts of Oklahoma may be impacted by frozen precipitation (snow or ice).  This may cause the wind chill temperatures we report on our maps to be warmer than expected.  

This Apparent Temperature map plots either:
  1. Wind Chill (degrees F) if temperatures are below 50 F and winds are greater than 5 mph,
  2. Heat Index (degrees F) if temperatures are above 80 F, or
  3. Current Temperature (degrees F) if neither wind chill or heat index is a factor.
This map is updated every hour using data from NOAA's National Weather Service.
