MinRHs to drop into the 30-40% range across portions of the
Central Mountains with a light westerly wind. In the late afternoon
and evening hours, some showers and thunderstorms have potential
to develop across the northern tier before a more widespread
soaking rainfall enters the area overnight into Tuesday.
