...Stormy weather pattern returning to the Pacific Northwest and
heavy rain remains likely for the Gulf Coast...

The low pressure system currently over the Great Lakes region
Tuesday morning will continue tracking towards New England by
Wednesday, before quickly moving out to sea.  Periods of heavy
rain and thunderstorms are likely from eastern Texas to the Ohio
Valley along the trailing cold front.  Farther to the north from
Wisconsin to northern New England, it will be mainly in the form
of wintry weather, with freezing rain and sleet across the Great
Lakes region, and snow for interior New England once the low
intensifies off the coast on Wednesday.  

Heavy rain chances will continue across the Gulf Coast region
through the middle of the week as the southern portion of the cold
front is forecast to stall out.  The highest rainfall totals are
anticipated from southeast Texas to Mississippi, where a few
inches of additional rainfall is possible.  Some strong
thunderstorms are also likely south of the front, and could
produce localized flooding.

The weather pattern across the Pacific Northwest will become quite
active
starting Tuesday with heavy rain and mountain snow, compliments of
strong
onshore flow from the next approaching storm system over the
northeast
Pacific Ocean.  By Wednesday, this moisture should begin reaching
California and the northern Rockies, with the heaviest rain
expected for
the coastal mountain ranges from northern California to
Washington.
Strong and gusty winds are also likely near the coast and for the
higher
elevations.
