NWS Sterling for Sunday.... like most systems we are in wait and see mode.
A wave of low pressure, infused with tropical moisture from the
remnants of multiple East Pacific systems, treks toward the OH/TN
Valleys Saturday into Saturday night. The track of the low beyond
this point will depend on (1) where exactly the stalled front is,
and (2) the strength of a transient blocking high pressure to the
north. Rain or showers become increasingly likely for much of the
region Saturday night into Sunday, with a soaking rain possible if
the wave of low pressure is a bit more organized/closer to the area.
