Oklahoma East Water Vapor

This satellite image displays the lower-level water vapor wavelength band (band 10) of the three water vapor bands from the GOES-16 satellite. The water vapor depicted by this particular band is typically at a pressure level around 700 millibars (approximately 10,000 feet). With sufficient surface-based convection, dry air (oranges/reds) at this level can often be translated to the surface, resulting in very low relative humidity and increased fire danger. The map, useful during day or night, has a spatial resolution of 2 km with a central wavelength of 7.3 microns. This image is provided by the College of DuPage and is updated every 5 minutes. The time of the image is shown beneath the map in UTC time (CST = UTC - 6 hours; CDT = UTC - 5 hours). Click here to see an animation of this map with county boundaries over the past four hours.
