WCCO meteorologist Mike Augustyniak is tracking the isolated severe storms possible over the next few hours, with hail the main concern.

Morning sunshine will give way to a fair amount of clouds this afternoon due to the increasing cold air aloft. Please direct all questions and comments regarding GOES-E (GOES-16) images to: Meteorologists rely on weather radar to see developing storms, and now you can, too. Unless otherwise noted, the images linked from this page are located on servers at the Satellite Products and Services Division (SPSD) of the National Environmental Satellite, Data, and Information Service (NESDIS). Since hail can cause the rainfall estimates to be higher than what is actually occurring, steps are taken to prevent these high dBZ values from being converted to rainfall.Satellite | Radar | Aircraft Recon | GIS Data | Analysis Tools The second of two noreasters began strengthening after the first dumped heavy rain from New Jersey to New England, and it will bring powerful winds with it- and maybe even snag the last name on. Hail is a good reflector of energy and will return very high dBZ values. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Depending on the type of weather occurring and the area of the U.S., forecasters use a set of rainrates which are associated to the dBZ values. The higher the dBZ, the stronger the rainrate. GeoColor is a multispectral product composed of True Color (using a simulated green component) during daytime, and an Infrared product that uses bands 7 and 13 at night. Typically, light rain is occurring when the dBZ value reaches 20. The winter storm continued to hurl rain, snow and ice across New England Friday, and AccuWeather forecasters say some more wintry conditions will develop this weekend in the Northeast. The scale of dBZ values is also related to the intensity of rainfall. GOES-16 Band 13 corresponds approximately. This channel is useful for detecting clouds all times of day and night and is particularly useful in retrievals of cloud top height. for LOCAL WEATHER: additional OPTIONS: City, ST -or- ZIP code -or- ST. The value of the dBZ depends upon the mode the radar is in at the time the image was created. 10.3 µm - 'Clean' Longwave IR Window Band - 2 km resolution - Band 13 at 10.3 µm is an infrared window, meaning it is not strongly affected by atmospheric water vapor. Notice the color on each scale remains the same in both operational modes, only the values change. The Northeast region radar loop is produced by combining imagery from multiple individual radar sites into one single regional radar loop via the Multi-Radar/Multi-Sensor System (MRMS). The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). Each reflectivity image you see includes one of two color scales. The dBZ values increase as the strength of the signal returned to the radar increases. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Low pressure is moving across Lake Superior. Loop provided by College of DuPage NexLab. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). Strong to severe thunderstorms moved across the Midwest Friday evening. "Reflectivity" is the amount of transmitted power returned to the radar receiver. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
