Another Clipper to Bring Snow Monday; Gulf of Mexico Storm to Bring Heavy Rain

A second clipper will move through the northern Plains into the Great Lakes, Ohio Valley, and Northeast Monday and Tuesday with additional light snow which may impact travel. A storm is expected to develop across the western Gulf of Mexico Monday and track east through Tuesday crossing Florida with gusty winds, heavy rain, and thunderstorms. Read More >

Coverage Map Notes

The coverage statistics and maps are calculated using a computer model and station data assuming ideal conditions. Coverage may be 5 to 10 percent below the computer predicted coverage for the following reasons:

  • The computer model is sensitive to antenna performance. Antenna performance is a function of local conditions, causing signals to be stronger signal level in some directions than others.
  • Placement of NWR antennas is dictated by the tower owner, which may result in a less than ideal set up.
  • The antenna may be affected by nearby structures or bodies of water.
  • In some special instances, the antenna may have been intentionally adjusted to be "directional" and provide better coverage to a specific area to the detriment of other areas.
  • Because of variations in local site conditions, the performance of an individual transmitter and antenna may be less than predicted or expected.
  • Seasonal environmental conditions, such as icing or heavy rain, affect performance of a transmitter station and its various components, particularly those subject to continuous weather exposure.
  • The coverage maps are shown in a single color format, which relates to an estimated signal level.
