.DISCUSSION...
Per your request, spots will be sent at 1800 EDT going forward, with
a start time of 0800 the following morning. This request has been
communicated to other forecasters here.
Expect Saturday to be similar to Friday, with decent daytime mixing
and RHs bottoming out in the low 30% range. The most aggressive
forecast models do not bring RHs below 30%...and there`s good
agreement that there will simply be too much moisture aloft for
dewpoints to drop significantly lower than forecast. Winds during
the afternoon will be lighter than on Friday...with minimal gusts
expected.
Winds will remain light on Sunday. As moisture continues to build
into the region, expect RHs to struggle to drop below the upper 30%
range, and cloud cover to steadily increase from Saturday night
onward. Nonetheless, daytime mixing will be impressive on Sunday.
