4:30 p.m. update: The flood watch for the Baltimore region has been canceled, though the coastal flood advisory remained in effect. Forecasters are calling for up to an inch of rainfall.
Original post, as of 3 p.m.: A high chance of rain throughout Tuesday afternoon and evening has caused the National Weather Service to issue a flood watch for much of the Baltimore region, starting at 3 p.m.
Streams and low-lying areas could flood, and minor tidal flooding is also possible, the weather service said. A coastal flood advisory for the western shore of the Chesapeake Bay, including Baltimore and Anne Arundel, Baltimore and Harford counties, was in effect Tuesday afternoon through noon Wednesday.
Light rain started around the region by about 3 p.m. and was expected to get heavier in the evening, with 1-2 inches possible. Light rain could continue into early Wednesday morning.
The rain is coming on the southern side of a potent winter storm that bore down on the U.S. southern Plains on Monday. It dumped more than a foot of snow and creating blizzard conditions in Oklahoma, Texas and parts of Kansas still digging out from a winter storm last week.
Interstate and smaller highways in the Texas and Oklahoma panhandles and parts of Kansas were closed by the heavy and drifting snow that cut visibility and forced flight cancellations at airports across the region.
But the heavy snowfall is expected to stay to the north and west sides of the storm, with an area of ice in between. An ice storm warning was in effect Tuesday for parts of West Virginia, with a winter storm warning in Garrett and western Allegany counties calling for as much of a quarter inch of ice there.
One report made to the weather service's Pittsburgh office, which covers Garrett County, said a tenth of an inch of ice had accumulated near Oakland as of about noon.
In the Baltimore area, mild conditions are expected to be behind the storm. Partly sunny skies with highs in the mid-50s will likely move in on Wednesday afternoon.
