NEXRAD – Select the NEXRAD Softkey to show NEXRAD weather and radar coverage information. Areas where radar coverage is not available will be shown in grayish-purple. The display is updated every five minutes.

NEXRAD Limitations

Certain limitations exist regarding the NEXRAD radar displays. Some, but not all, are listed here:

NEXRAD base reflectivity does not provide sufficient information to determine cloud layers or precipitation characteristics (hail vs. rain, etc).

An individual NEXRAD site cannot depict high altitude storms at close ranges, and has no information about storms directly over the site.

The resolution of displayed NEXRAD data is 4 square kilometers. Therefore, when zoomed in on the display, each square block is 2 kilometers on each side. The intensity level reflected by the square will be the highest level sampled within the square area.

ECHO TOP – Select the ECHO TOP Softkey to show the location, elevation, and direction the highest radar echo. This may not indicate the top of a storm or clouds, only the highest radar return echo. ECHO TOPS cannot be displayed along with NEXRAD and CLOUD TOPS. When ECHO TOPS is activated, NEXRAD and CLOUD TOPS are removed. Refer to the Legend for a description of the ECHO TOPS coding. The display is updated every 7.5 minutes.

CLD TOP – Select the CLD TOP Softkey to show the cloud top altitude determined from satellite imagery. The display is updated every 15 minutes.

LTNG – Selecting the LTNG Softkey shows the location of cloud-to-ground lightning strikes. The display is updated every five minutes.

NOTE: Strikes depicted represent cloud to ground strikes within a 2 kilometer radius of the actual strike location. Therefore, the exact location of the strike is not displayed.
