Aside from less forcing, there’s a trend up here for some drier sfc air to work in overnight. That may be attributing to some of the sharp cutoff in S NH.
51° here with full sun in downslope land. I honestly figured you’d be colder than 48°.
High here was 52°. If we get our typical 25° drop on a rad night I’ll be around 27°. Seems about right.
