The 2-7 day forecasts have been replaced with a 3 day forecast, broken into 12 hour increments:
The way NWS works is that the URLs are update 2x a day and when the update would happen you would switch from
Day 2 1pm, Day 3 1pm, Day 4 1pm etc
to
Day 2 1am, Day 3 1am, Day 4 1am etc
The effect was that all of the sudden the forecast would look "better" (snowier) but actually all you were seeing was the effect of colder overnight temps.
Works better for me anyway.
