...Pacific storm to make for a wet and wintry start to the week in the
...Low pressure system lingering over the Northeast expected to bring
additional snowfall for northern New England...
...Developing area of low pressure expected to spread heavy rain and
thunderstorms quickly across the Deep South to the Southeast...
Quite an active weather pattern is expected for the next few days as three
major systems are expected to affect many parts of the country. The low
pressure system responsible for widespread precipiation from the Great
Lakes to the Northeast will weaken very slowly as it lingers over the
Northeast for the next couple of days. This will keep a good chance of
snow across northern New England through Wednesday morning where a few
inches of additional accumulations can be expected. A cold front behind
an intensifying storm off the New England coast will usher in cooler
temperatures and drier conditions through much of the eastern U.S. today.
This storm system will also push a back door cold front down from New
England into the Mid-Atlantic on Tuesday as rain ahead of a low pressure
system from the Deep South quickly moves into the Southeast and the
Mid-Atlantic by Tuesday evening. This low pressure system is currently
developing over the southern High Plains as an upper-level disturbance
tracks across the Southwest. The storm will tap into Gulf moisture
leading to a blossoming of showers and thunderstorms from the southern
Plains Monday evening to the lower Mississippi Valley some time Monday
night with a good chance for a quick round of heavy rain. By Tuesday, the
storm will advance rapidly into the Southeast where heavy showers and a
threat of severe thunderstorms are possible. By Wednesday morning, the
storm center should continue to move rapidly off the Southeast U.S. coast,
ending the rain over the Southeast. Farther north, some rain should
linger over the Mid-Atlantic and the Ohio Valley near a surface trough.
In the West, a northeast Pacific storm will roll into the Northwest on
today, 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.
