A Winter Weather Advisory remains in effect until 6 am EST
Thursday.

An area of low pressure will continue to intensify off the mid-
Atlantic coast overnight. Precipitation will continue across the
Potomac Highlands and temperatures across the higher elevations
will be cold enough for snow. One to two inches of snow is
expected across elevations above 3500 feet. Precipitation will
change to all rain Thursday morning as warmer air works its way
into the region.

A Winter Weather Advisory means that periods of snow... sleet... or
freezing rain will cause travel difficulties. Be prepared for
slippery roads and limited visibilities... and use caution while
driving.

... Street flooding...

Several inches of rain are possible over the next couple of
days... especially along and east of Interstate 95. The rainfall
will be steady and prolonged... therefore flash flooding or river
flooding due to heavy rain is not expected.

However... this time of year is prime for producing high standing
water on roads and streets... especially in urbanized areas.
It is also more difficult for rainfall to run off into tidal
areas because of higher than normal tides. It is a good idea to
check storm drains in your area and clear out fallen leaves and
debris. Baltimore City... Washington DC... Alexandria and Annapolis
are at greatest risk for street flooding.
