Ok, I know I said this the other day and nothing happened, but this afternoon into the evening there is a good chance for scattered thunderstorms. What happened the other day is that the frontal boundary I had mentioned did not shift where it was forecast to shift, causing low temps for central and Southern MD, while those in Carroll county and west saw some storms as their temps where in the 70s and humid. Last night's storms in northern central MD were impressive, and I know I didn't say anything about them happening, but that is because the data originally indicated no threat. I know it's not an excuse, but I find it interesting that thus far this Spring's storms are resembling our Winter weather in that places west and north of us are getting the storms and rains.
Today's storms, though, are a different set up, and once the marine layer (that which is now causing the fog and clouds) lifts, as it should, the day will heat up in time for an approaching cold front to arrive from the west. The cold air mass hitting the warmer humid air mass gives us the potential for strong storms.
THREAT: The main threat will be strong gusty, potentially damaging winds and hail. Frequent lightning is to be expected as well. No tornadoes expected.
TIMING: Storms should hold off until late this afternoon, more than likely after 4:00pm into the evening hours. I expect storms to be out of the area before midnight.
These storms will be scattered and pop up in nature. Keep an eye on the sky if you are outside. Remember, if you can hear the thunder, you are close enough to be hit by lightning. Just sayin'.
