After more flooding occurred in the D.C. and Baltimore Metro's last night, what can be expected for today?

Yesterday brought with it more storms with flooding through the D.C. and Baltimore Metro areas. Unfortunately, there is another potential for flooding today as an area of low pressure advances from the west. Not only is there the chance for flooding, but also some isolated severe weather, as some of the storms may also have damaging wind gusts. With the already saturated grounds from recent storms and weakened trees from the derecho a few weeks ago, it may not take as much now for trees to fall.

Check out the thunderstorms that came through the region last night. I remember looking at them on Doppler Radar before heading to bed early and thinking they were definitely going to reach D.C. Sure enough, 10pm rolls around and it was rocking and rolling outside my bedroom! Here's a picture I snapped of the line last night. (On a side note, I went to bed at 8pm as I had to wake up around 3 a.m., just sayin..)

Line of thunderstorms last night

You can see the line extended from Carroll and Howard Counties south into Fairfax County in Virginia. Here are some of the heaviest rainfall totals from yesterday

Ocean City, MD    4.28" (No Joke!)

Inner Harbor, MD    3"

The Banner School, Frederick, MD    2.73"

Lowell School, D.C.    1.27"

Children's Hospital, D.C.    1.24"

WTOP Radio, NW D.C.    0.79"

Washington-Lee HS, Arlington, VA    0.73"

Here is a look at the HPC forecast for rainfall today across the country. This could easily change and be a lot higher if one storm moves over your region, so take it with a grain of salt. I just wanted to show it to display there is a chance for some heavy rainfall not only here but south as well in case you're traveling today. I-95 south in Virginia through eastern North Carolina does not look friendly for travelers today through tomorrow.

Precipitation forecast from the HPC through Saturday

As far as severe weather, there is a slight risk for severe storms as well from the Storm Prediction Center in Norman, OK. The highest threat in any storms today will be in the form of damaging wind gusts. I think this would be an isolated threat and the main focus should be on flooding.
