Incorrect date and high temp in 7-day forecast

[ndb-gov]

Description

I viewed the 7-day forecast for Portland, OR on beta.weather.gov on 12/4 at 10:28pm Pacific time and saw a couple of errors:

1. Both "Today" and "Tomorrow" showed 12/5
2. For "Today", the high and low temperature both showed 35 degrees F. (The high temperature that day was in the high 40s.)

I didn't reproduce the issue when I checked again at 6:19pm Pacific on 12/5. (I'm curious whether there is a date localization issue since at the time I saw the bug, it was 12/5 in UTC and ET but 12/4 in PT.)
