How far it goes: 48 hours (2.0 days), one value per 60 minutes
The primary forecast source was unavailable, so this location is running on the backup source, which publishes a shorter hourly horizon.
Columns are hidden when the source does not publish that measurement for this location, rather than showing an invented number.

Hourly timing is the least certain part of any forecast, and days six through eight are far less certain than tomorrow. Rain can arrive earlier or later than the hour shown. Official warnings always take precedence.
