Tropical Depression Two is forecast by the National Hurricane Center to
strengthen into a tropical storm today as it heads west northwestward
toward the Southeast U.S. coastline. The system will begin to spread
showers and thunderstorms into eastern portions of the Carolinas by late
today. The system is forecast to linger along the coast of the Carolinas
into Monday. Moisture streaming north along with an approaching cold front
will spread rain and thunderstorms north into the Mid-Atlantic and
portions of the Northeast by Sunday. Heavy rain and flash flooding are
possible for some areas from South Carolina northward to portions of the
Northeast through Sunday.
A slow-moving frontal system will bring scattered to numerous showers and
thunderstorms from the southern plains to the Upper Midwest today. The
cold front will move east across the Great Lakes on Sunday with scattered
showers and thunderstorms. The southern end of the front will stall across
the southern plains, keeping areas of showers and thunderstorms a daily
occurrence in that area. Locally heavy rain and flash flooding will also
be possible for portions of the southern and central plains.
Scattered showers and thunderstorms will also be possible across the
Rockies through the next couple days as a frontal system moves slowly east
across the region and weakens. Another Pacific cold front will move into
the northwestern U.S. bringing showers today. This front will move into
the interior West Sunday into Monday, bringing another round of scattered
showers and thunderstorms.
A ridge of high pressure at the mid and upper-levels of the atmosphere
will keep warm temperatures in place from the Great Lakes to the
Mid-Atlantic and Northeast today. Afternoon high temperatures are forecast
to be 10 to 20 degrees above average for many areas.
