Mission statement






* Radar of approaching precipitation
The Forecast Radar image shows where precipitation is expected to be in the next 20-30 minutes. Precipitation type is indicated by the color - green is rain, pink is a mix of rain, freezing rain, sleet, and/or snow, and blue is snow.

Nowrad weather radar is updated 4 times per hour and distinguishes between rain, sleet, and snow. 

     Rain is falling where the image shows green (light rain), yellow (more intense rain), or red (very intense rain).  Reload the link if think you are not getting the latest image.  Subtract 4 hours to convert Greenwich Mean Time (GMT) to Eastern Daylight Savings Time.  Subtract 5 hours to convert to Eastern Standard Time.  Converting UTC time to Local time
