Wind Speed & Gusts, with Arrows

The Wind Speed and Gusts, with Arrows map displays the current wind speeds (in mph) at each Mesonet site. Arrows indicate the wind direction at each station. Wind gusts are also plotted when either:
  • The wind gust exceeds 15 mph
  • The wind gust is more than 5 mph greater than the wind speed.


This map is updated every 5 minutes.
Wind Speed & Gusts, with Barbs learn more

Wind Speed & Gusts, with Barbs

The Wind Speed and Gusts, with Barbs map displays the current wind speeds (in mph) at each Mesonet site. The wind barb is an "arrow" that depicts the wind speed and direction. The "feathers" of the arrow indicate the wind speed while the dot end of the arrow indicates the direction the wind is blowing toward. Wind gusts are also plotted when either:
  • The wind gust exceeds 15 mph
  • The wind gust is more than 5 mph greater than the wind speed.


This map is updated every 5 minutes.

Gradient-Filled Wind at 10 m

The Gradient-Filled Wind Map displays the average wind speeds (in miles per hour) at 10 m (33 feet) across Oklahoma. Arrows indicate the average direction the wind is blowing toward across the state.

Maximum Gusts in the Past Hour

The Maximum Wind Gusts for the Past Hour map displays the highest wind gust (in mph) recorded at each Mesonet station in the past hour. This map is updated every 5 minutes.
Maximum Gusts since Midnight learn more

Maximum Gusts since Midnight

The Maximum Wind Gusts since Midnight map displays the highest wind gust (mph) recorded at each Mesonet station since midnight. This map is updated every 5 minutes.

Yesterday's Max Wind Gusts

The Yesterday's Maximum Wind Gusts since Midnight map displays the highest wind speed (mph) recorded yesterday at each Mesonet station .
Current Mass Convergence learn more

Current Mass Convergence

Mass convergence (and divergence) measured by the Oklahoma Mesonet indicates rising or sinking air near the ground at a particular location based on the change in wind speed over a certain length. If winds speed up at a location, or flow away from each other, mass divergence occurs. The loss of mass near the ground due to divergence requires that air from above sink to fill the void. Therefore, areas of mass divergence are associated with downdrafts. Clear skies or thin cloud layers are often found with downdrafts since it is difficult for clouds to form in areas with sinking air.

Mass convergence is found in areas where winds come together. As winds come together, mass builds up and therefore causes air to rise, creating an updraft. Convergence may occur due to topography or daytime heating, and can be especially strong along fronts and dry lines. Meteorologists look for these areas of strong convergence, or updrafts, for possible storm development if the proper ingredients are present.
Gradient-Filled Wind at 2 m learn more

Gradient-Filled Wind at 2 m

The Gradient-Filled Wind Map displays the average wind speeds (in miles per hour) across Oklahoma at 2 meters (6 feet) above the surface. Arrows indicate the average direction the wind is blowing toward across the state at 10 meters (33 feet) above the surface.
Dispersion Conditions learn more

Dispersion Conditions

Dispersion condition categories indicate the ability of the atmosphere to dilute airborne particles (i.e. smoke, pollution, pesticides). Atmospheric dispersion includes both horizontal and vertical dilution of released vapor-like particulates. The higher the dispersion number category the faster atmospheric dilution is likely to occur. When conditions are poor (2) or very poor (1) vapors can stay concentrated for long periods of time. Dispersion categories are: Excellent (Category 6); Good (Category 5); Moderately Good (Category 4); Moderately Poor (Category 3); Poor (Category 2); and Very Poor (Category 1).
