...Weekend storm system to generate showers and thunderstorms in
the Northeast and Mid-Atlantic, snow in the northern
Appalachians...

...Pacific storm to make for a wet and wintry start to the week in
the Northwest...

...Developing area of low pressure to cause wet and stormy
conditions from the Southern Plains to the Southeast...

The storm system responsible for Saturday`s episodes of severe
weather and flash flooding in portions of the Mississippi and Ohio
Valleys will track through the Great Lakes this evening. A cold
front tracking across the South and Mid-Atlantic will usher in
cooler temperatures and drier conditions on Monday. Meanwhile,
showers and thunderstorms will track across the Mid-Atlantic and
southern New England tonight while northern Maine witnesses
measurable snowfall. The snow in northern New England is a result
of a developing coastal low east of the Massachusetts Capes.
Portions of northern Maine can expect over 6 inches of snow
tonight before the snow tapers off Monday night. In wake of this
storm system, a coastal front will push south from southern New
England Tuesday to the Mid-Atlantic on Wednesday forcing cooler
temperatures to stick around through mid-week.

In the West, a northeast Pacific storm will roll into the
Northwest on Monday bringing widespread showers and mountain snow
to the Pacific Northwest, northern Great Basin, and Northern
Rockies. The Cascades will measure snowfall in feet through
mid-week while interior mountain ranges such as the Bitterroots,
Sawtooths, and Tetons also pickup heavy snow. In addition, a cold
frontal passage will lead to colder temperatures across the
Northwest Monday night and lasting into the middle of the week.

Farther south, an upper-level disturbance will track across the
Southwest Monday morning. Ahead of this feature, an area of low
pressure will form in the southern High Plains Monday afternoon.
The developing storm system will tap into Gulf moisture leading to
a blossoming shower and thunderstorm activity from the Southern
Plains Monday evening to the Lower Mississippi Valley some time
Monday night. There is a chance for flash flooding in parts of the
South Central region Monday afternoon and into the overnight
hours. By Tuesday, the storm will advance east and into the
Southeast where heavy showers and a threat of severe thunderstorms
are possible.
