...THERE IS A MARGINAL RISK OF EXCESSIVE RAINFALL OVER PORTIONS OF
THE SIERRA NEVADA...

At 12z Saturday the cold front and associated moisture plume will
be dropping south across the central Sierra Nevada. By this time
rainfall intensity will be decreasing, and the axis of better
moisture will be dropping south of the areas hardest hit over the
past few days. Thus the flood risk should be pretty low Saturday
morning along this southward dropping front.

Some weak post frontal instability is forecast which could allow for
locally heavy showers in the wake of the front over the western
slopes of the central Sierra Nevada. Not expecting anything too
intense or widespread, however there is at least a chance that a few
cells could drop a quick 0.5" or so of rain. This would be falling
over increasingly saturated ground, and so a localized flood risk is
possible. Thus we will maintain the small Marginal risk where a few
heavier post frontal showers are possible Saturday.
