OCF One week detailed weather forecasts for WA :
Interior
from
Forecast base time 4pm EST, 12/08/26


Wed 5 Aug 2026: The changes to the Daily Weather Summary and Daily Climatic Data sections of AWN are taking longer than anticipated. The switch to new sources of data has required more reprogramming than I thought would be needed, but the work is about 75% done. When the new programs are complete, all DWS and DCD data pages for this interim period back to 7 July will be recreated.

For more information on the changes and the reasons for them, go here.

OCF forecasts and other parts of the site are not affected.

This yellow box will update as changes are made.
