Description:
A plan view map of 114-hour, 6-hourly accumulated precipitation forecast from the Global Forecast System over the Southeast U.S. Precipitation amounts are shaded in inches at 0.01", 0.05", 0.10", 0.25" and 0.50" levels. The precipitation is forecast to occur in an overrunning band from northwest Tennessee east-southeastward into the Carolinas and Georgia. The Columbia SC National Weather Service Forecast Office is highlighted with a red dotted polygon.

Description:
Idealized graphic depicting a forecast MCS cloud shield at 15 UTC on a summer day, contoured in gray and black (shadow) in a forecast model that results from a convective "bulls-eye" upstream of Topeka, Kansas. While an MCS actually took place, it took place farther south and west (shaded in gray and black), and the resulting cloud shield is not expected to affect Topeka.

Description:
This image has two panels. The left panel shows the locations a pitcher needs to throw a ball in order for his running friend to catch it. The friend runs from right to left. The right panel shows the same situation but this time the friend is tired and runs slower. The pitcher will throw ahead of the friend and miss her.
