Weather Underground Forecast for Saturday,September 21,2013.
An extensive cold front will bring widespread showers and thunderstorms
to the Southeast, Midwest, and Northeast on Saturday, while a separate
cold front will bring wet weather to the Pacific Northwest.
A cold front extending from Texas to New England will bring showers and
thunderstorms to a great majority of the East Coast on Saturday, as
multiple low pressure systems will be embedded in the cold front. Texas
will get plenty of relief from their drought as remnants of Tropical
Cyclone Manuel will feed moisture into a low pressure system sitting off
of southeast Texas. Parts of Texas, as well as Louisiana,
Mississippi,and Alabama, may experience flash flooding as thunderstorms
will produce heavy rainfall for extended periods of time.
Rain from the same cold front may also bring flooding to the
Mid-Atlantic and Northeast, as a separate low pressure system is
expected to move over the Ohio Valley on Saturday. Pennsylvania, New
York, and parts of southwest New England will be the most prone to
flooding as this low pressure will feed moisture in from the south.
Northern Maine is likely to avoid wet weather on Saturday as the cold
front is expected to brush past the region.
Meanwhile, a relatively strong cold front for this time of year will
move through the Pacific Northwest on Saturday, bringing some early
rains to Washington, Oregon,and in particular northern California. Rain
may extend as far south as Central California, although it will be
fairly scattered. Temperatures are expected to drop 5 to 10 degrees as a
result of the cold front. The Southwest will avoid wet weather on
Saturday, although temperatures may drop a bit due to the previously
mentioned cold front.
The Great Basin will also experience spotty showers and thunderstorms,
which may not bode well for recently active flood zones in the Rockies.
