Gulf Low Satellite Image

This is a great look at the low pressure system that will affect our weather here in Middle TN this system moves north and east...moisture will overspread the southeastern region of the country and, with our cold temperatures, will cause some frozen precip to fall...the timing of the precipitation arriving along with the cold air in place are the biggest pieces to the puzzle!

Meteorologists use color enhanced imagery as an aid in satellite interpretation. The colors enable them to easily and quickly see features which are of special interest. Usually they look for high clouds or areas with a large amount of water vapor. In an infrared (IR) image cold clouds are high clouds, so the colors typically highlight the colder regions. The bar on the right side of the image indicates the pixel brightness values for the corresponding color.
