...There is a slight risk of severe thunderstorms over portion of
Florida...

...Wet snow possible from parts of the Central Appalachians to New
England...

...Heavy precipitation possible over parts of the Pacific
Northwest and Florida...

A developing storm along the Southeast Coast will deepen
significantly as the system moves northeastward along the East
Coast to the Canadian Maritimes by Thursday morning.  The dynamic
storm will produce light to moderate rain over parts of the
Southeast on Tuesday evening that will become moderate to heavy
rain over parts of the Mid-Atlantic into Southern New England
Coast by Wednesday morning.  The moderate to heavy rain will
linger over Southern New England Coast through Wednesday evening. 
Wet moderate snow will develop over the Central Appalachians into
the Northern Mid-Atlantic that will move to the Northeast by
Wednesday evening.  The snow will wind down to light snow over
parts of Northern Maine by Thursday morning, Thanksgiving.  In
addition, showers and thunderstorms will develop over parts of
Florida on Tuesday evening ending by Wednesday morning. 

Meanwhile, another storm over the Northern Plains will move
southeastward to Eastern Ohio Valley/Central Appalachians by
Thursday, Thanksgiving.  The system will produce light snow over
parts of the Northern Plains that will move into Upper Great Lakes
and the Western Ohio Valley by Wednesday evening.  The snow will
taper off to a small area over parts of the Central Appalachians
on Thanksgiving. 

A weak boundary extending from the Pacific Northwest to the
Northern/Central High Plains will aid in focusing onshore flow
from the Pacific to produce areas of moderate snow from the
Northern Intermountain Region/Northern Rockies through
Thanksgiving morning.  Light snow will develop over parts of the
Northern/Central Rockies into the parts of the Northern/Central
High Plains through Thursday.  Light to moderate rain will develop
over parts of the Pacific Northwest/Northern Intermountain Region
through Wednesday morning.  Light rain will continue over parts of
the Northwest on Wednesday evening.  Light to moderate rain will
return to the Pacific Northwest Coast by Thursday morning,
Thanksgiving, ahead of the next boundary.
