DISCUSSION:

A storm system will cross the area today through Sunday, with
peaks tonight and early Friday morning and Friday Night through
Saturday. The most likely outcome is for 2 to 4 inches total being
common over much of the area for Thursday through Sunday, with 3
to 6 inches in the favored hills and mountains. There is a 10 to
20 percent chance of thunderstorms as well. Peak rainfall rates
between 0.25 and 0.50 inches per hour will be common, but there is
a potential for rates of 0.5 and 1.0 inches per hour esp under
thunderstorms.

Periods of rain now seem likely Sunday through Tuesday. This rain
would be much lighter in both amounts and in intensity compared
to Friday and Saturday`s system.
