National Weather Service Philadelphia/Mount Holly Transitioning
to a New Format for the Area Forecast Discussion Beginning Jan 06
2026

Beginning at 1000 AM EST on Tuesday, January 06, 2026, the
National Weather Service Philadelphia/Mount Holly Forecast Office
will transition to a Key Message format for the Area Forecast
Discussion (AFDPHI).

This strategic change aligns the Area Forecast Discussion (AFD)
with an impacts-first message philosophy, enabling our office to
streamline communication and reduce redundancy. This transition
moves away from a strictly chronological layout to focus
immediately on potential weather impacts and hazards. By
prioritizing Key Messages, we aim to enhance clarity and eliminate
duplication within the Area Forecast Discussion.

A side-by-side comparison of the old format and the new format
templates can be found at:
