....Showers and thunderstorms are likely, with heavy rainfall and flooding
possible, across portions of the southern Plains over the next few days...

...More heavy is rain likely, with possible flooding, for portions of the
Northeast today...

...Dangerous surf and rip current conditions to spread north along the
East Coast over the next couple of days...

Unseasonably cool temperatures, with showers and thunderstorms, will
continue north of a cold front that has settled into southern Texas.  A
series of upper level disturbances interacting with a moist atmosphere is
expected to produce periods of showers and thunderstorms across portions
of the southern Plains over the next few days, with heavy rainfall amounts
and flooding possible.

It will remain unsettled, with seasonal to below-average temperatures,
across much of the Southwest today as well.  Then drier air will support a
diminishing chance for showers and thunderstorms, as temperatures begin to
climb during the latter half of the week.

Farther to the north, a cold front will focus showers and thunderstorms as
it advances southeast from the northern Rockies and Great Basin today,
into the northern Plains, upper Midwest, and the central Rockies on
Thursday.

In the East, a cold front will slowly advance east today, producing
additional showers and thunderstorms along the Eastern Seaboard, with
heavy rainfall amounts possible, especially for parts of the Northeast. 
Flood watches remain in effect for at least of portion of today from
eastern Pennsylvania, northern Delaware, and New Jersey into southeastern
New York and southern New England, where locally heavy downpours may
result in excessive runoff.

Also along the East Coast -- even though Hurricane Lee remains well
offshore, the storm is already producing dangerous surf and rip currents
along portions of the Southeast Coast.  These conditions are forecast to
spread northward along the remainder of the East Coast over the next
couple of days.
