PM Edition and sister program Afternoon Outlook were launched in fall 2003 and helped finish the compartmentalization of the TWC programming day, which transformed the network from just Weather Center to a myriad of different shows with set hosts and tone.

In the event an ongoing significant weather event occurred (e.g., severe weather outbreak, winter storm, hurricane threatening the United States), the weekday edition of PM Edition began one hour earlier, preempting long-form programming during the 3pm-4pm eastern timeslot.

With this change, PM Edition became a weekend only show, airing four hour-long blocks at 4pm, 7pm, 10pm and 1am Eastern Time.

Due to this, Maria LaRosa and Todd Santos began hosting the 4pm eastern hour of PM Edition.

The addition of Weather Center Live airing at 4pm Eastern Time was implemented into the weekend schedule, thus ending PM Edition's runtime.
