Here's a simulated radar evolution through the storm. Precipitation really fills in this afternoon. Watch for rapidly changing conditions! | US National Weather Service Gray ME

Combining data from multiple radars and multiple sensors (known as MRMS), we can put together a more complete picture of what kind of precipitation larger scale storms are producing. Looking at an animation of multiple radars over the northeastern U.S. we can see the counterclockwise rotation associated with the low pressure system affecting the area. https://www.nssl.noaa.gov/projects/mrms/ | U.S. National Weather Service (NWS)
