...Snow will develop over parts of the higher elevations of the
Cascades, Northern Intermountain Region/Northern Rockies on
Thursday, tapering off on Friday...

...There is a Slight Risk of excessive rainfall over parts of the
Southern High Plains on Thursday and over parts of the Southwest
on Friday and Saturday...

A quasi-stationary area of low pressure just off the Pacific
Northwest Coast will stream moisture into the Northwest Coast,
producing rain and highestelevation snow over the Cascades and
Northern Intermountain Region on Thursday into Friday evening.
Furthermore, a front extending from the Upper Great Lakes to the
Southern High Plains will advance eastward off the Northeast Coast
by Friday evening. The system will produce rain with embedded
thunderstorms over the Upper Great Lakes and rain over the Lower
Great Lakes through late Thursday night. Additionally, scattered
light rain showers will develop over parts of the Northeast
through Friday evening. Easterly flow off the Atlantic will bring
rain with embedded thunderstorms over parts of Florida through
Saturday.

In addition, upper-level energy will move over the Southern High
Plains, creating heavy rain over the region Thursday into Friday.
Therefore, the WPC has issued a Slight Risk (level 2/4) of
excessive rainfall over the Southern High Plains with these
thunderstorms on Thursday through Friday morning. The associated
heavy rain will create mainly localized areas of flash flooding,
with urban areas, roads, small streams, narrow canyons/gullies,
and burn scars the most vulnerable.

Moreover, flow off the Gulf of California and upper-level energy
will aid in producing showers and thunderstorms with heavy rain
over the Southwest on Friday. The WPC has issued a Slight Risk
(level 2/4) of excessive rainfall over the Southwest with these
thunderstorms on Friday through Saturday morning. The associated
heavy rain will create mainly localized areas of flash flooding,
with urban areas, roads, small streams, narrow canyons/gullies,
and burn scars the most vulnerable.

Flow off the Gulf of California will continue on Saturday,
creating heavy rain over parts of the Southwest and far
southeastern California. Therefore, the WPC has issued a Slight
Risk (level 2/4) of excessive rainfall over parts of the Southwest
and far southeastern California on Saturday into Sunday morning.
In addition, as moisture moves northward over the Great Basin,
rain with high-elevation snow will develop over parts of the Great
Basin, the Northern Intermountain Region, and the Central Rockies
from Friday into Saturday morning.
