...Heavy rain possible over parts of the Pacific Northwest...
...Heavy rain possible over parts of the Southeast Coast...
Moisture rich air will stream northward from the Atlantic over the
Southeast and upper-level energy will aid in producing showers and
thunderstorms over the Southeast and into parts of the Southern
Mid-Atlantic Coast through Monday evening. In addition, upper-level
energy over the Middle Mississippi Valley to the Ohio Valley will aid in
producing areas of showers and thunderstorms over parts of the region
through Monday morning.
A front extending from the Northern High Plains to parts of the Great
Basin will slowly move eastward to the Upper Mississippi Valley roughly
southwestward to the Great Basin by Monday evening. Showers and
thunderstorms will develop over parts of the Northern High Plains and move
eastward to the Upper Mississippi Valley by Monday. Behind the system
onshore flow off the Pacific will produce rain over parts of the Pacific
Northwest through Monday evening.
Elsewhere, monsoonal moisture and daytime heating will aid in producing
showers and thunderstorms over part of the Southern/Central Rockies and
parts of the Southwest/Great Basin on Sunday and Monday afternoon and into
the late evening.
