Today’s rainy weather in the Southeast is caused by a large swirling low pressure center which is moving slowly over the area.  The color-enhanced satellite water vapor image below shows how wrapped up the system is, with dry air in yellows and oranges and moist air in blue, green and white.  Note the pop-up moist convection in the southeast part of Georgia associated with thunderstorms which are forming there.  For an animated version, please visit https://go.wisc.edu/uiyan3.
