Satellites: NOAA-15 and NOAA-17, part of NOAA's 850km-high (530 mile-high) Polar Orbiting satellites

After yesterday's cold front moved into the southeast...now comes the snow.
Yesterday's cold front brought moving through collided with the moist air moving up from the Gulf of Mexico.
This image shows the classic weather pattern that includes
(a) the counterclockwise circulation characteristic of mid-latitude northern hemisphere systems,
(b) how that circulation brings the warmer moist air up from the Gulf, and
(c) how that circulation pas pulled arctic air into the southeast from the Upper Plains states.
Put all those together, and...snow for the southeast!
Also note how this system is pulling moisture off of the northern Atlantic Ocean and dumping it as snow in northeastern Canada.
