...Widespread showers and thunderstorms continues across the Ohio
Valley, Mid-Atlantic, and Northeast this weekend...

...Scattered showers and thunderstorms are expected ahead of a
frontal boundary across the Intermountain West and the Rockies...


A large upper level system across the Eastern U.S. keeps showers
and thunderstorms in the forecast from the Ohio Valley to the
Northeast this weekend. The most organized of the rainfall should
set up along the occluded front from the Great Lakes to the
northern Mid-Atlantic on Saturday, lifting northward into the
Northeast/New England by Sunday. The cold front is forecast to
linger near the coast the next couple of days which may allow for
heavier rainfall totals across the Outer Banks and coastal New
England as well. Given heavy rainfall in these areas already the
past several days, localized flash flooding remains a threat.

A cold front pushing slowly across the northern Intermountain West
today will continue to allow for showers and thunderstorms to
develop across the Mountain West and into the Four Corners region
this weekend. Heavier rainfall may be possible across the favored
terrain of the northern Rockies and High Plains by Sunday as the
front moves into the region. Farther west, rain will be on the
increase across the Pacific Northwest as the upper level system
approaches the West coast. Heavy rainfall is possible along the
coastal ranges of northern California and southwest Oregon
Saturday evening into Sunday.
