What is SkyWarn?

The Southwest Missouri Regional Skywarn Net is sponsored by the National Weather Service Office in Springfield, Missouri and the Amateur Radio Clubs of Missouri and Southeast Kansas. It is affiliated with the ARRL, ARES and RACES organizations. Member stations of these groups provide emergency tactical communications for the American Red Cross, the National Weather Service, and any federal, state, or local emergency management agency. The primary repeater for the Skywarn system is the 145.490 MHz Repeater with a PL tone of 136.5 Hz. If this repeater is unavailable, the secondary system will be the Southwest Missouri Linked Repeater System (otherwise known as the SMLRS).

When is the Skywarn Net Active?

The Southwest Missouri Skywarn Net is activated at the request of the National Weather Service office in Springfield, MO any time there is an imminent threat of severe weather in the Springfield office forecast area.

Reports needed during these active Skywarn nets are:

  1. Hail the size of a Quarter or larger
  2. Winds in excess of 58 MPH or breaking tree limbs 3 inches or larger
  3. Property damage
  4. Continuous cloud-to-ground lightning
  5. Sighting of a wall cloud, funnel cloud, or a tornado
  6. Also, other reports of “current conditions” may be requested by the meteorologists whether they are of a severe nature or not.

During a period of severe weather activity

During threatening weather conditions, identified watches, or warnings, or other emergency conditions in the area, all stations are encouraged to monitor NOAA Weather Radio, Local Radio or TV Broadcasts,to keep abreast of the situation until it no longer exists. It’s also preferable during these times that normal conversations cease so that stations reporting severe weather conditions may acquire the repeater. Also, stations are advised to make needed preparations for protection of your family, home, and station equipment and to prepare for possible activation of a Skywarn or other emergency services net with little or no advance notice.
