| Sea Level Pressure, Surface Wind & Infrared Satellite -
The satellite image identifies cloud locations. As the storm develops and moves west to east across the country a comma
shape develops. Winter-type precipitation is found in the 'head' of the comma and thunderstorms are found along
the warmer 'tail'.
The sea level pressure pattern coupled with the satellite allows meteorologists to identify where the clouds are
relative to the center of the storm. The green arrows provide information about the wind. Longer arrows indicate faster winds,
shorter arrows are slower winds. The arrows point in the direction the wind is blowing toward.
