RADAR

National Doppler Radar Image

This radar mosaic is created twice per hour, from observations taken at WSR-88D sites around 00:15 and 00:45. The mosaic is composed of the highest observed reflectivity category within map grid boxes approximately 10 km (~5 nautical miles) on a side. It is designed to give you an overall picture of the position, movement, and evolution of precipitation on a synoptic scale. Click on the mosaic for enlargement of any area. Animation is also available. (NWS)

National Radar Image

Radar imagery displays areas where precipitation is occurring, the intensity of the precipitation, and the type of precipitation (rain, snow, mixed). Mixed precipitation includes any combination of rain, snow, sleet or freezing rain. Clicking on the area of interest will display an enlarged image with a 24 hour archive. (Intellicast)

National Radar Summary

The radar summary graphics display cell movement and direction by arrows, with speed in knots, and the echo top heights in hundreds of feet. The NA on the chart indicates that the radar report from that station was "Not Available", and NE shows that the radar was seeing "No Echoes". Severe weather watch boxes are also plotted. Clicking on the area of interest will display an enlarged image with a 24 hour archive. (Intellicast)
