These storms are also producing torrential downpours.
All of central Maryland is under a Severe Thunderstorm Watch through 8 p.m., and Severe Thunderstorm Warnings have been issued for some areas throughout the day.
A watch means conditions are favorable for damaging thunderstorms in and around the watch area.
With showers and storms training over the same general area Monday afternoon and evening, the threat exists for some street and urban flash flooding. A severe thunderstorm watch is also likely this afternoon. Hail, damaging winds and significant rainfall are expected.
The National Weather Services cautions people in the line of this storm to move to an interior room on the lowest floor of a building. Although not becoming super dry initially, it should still become more comfortable tomorrow with refreshing air Wednesday and most of Thursday. The freshening winds will cause wind shear (the difference in wind speed between the ground and regions aloft) to increase, to about 30 to 40 knots.
A few of the storms we see could become strong to severe.
Morning: Isolated shower/storm, mainly west of I-91. The line may wane a bit as it crosses the spine of the Appalachians, but then is expected to re-intensify on the eastern side.
