update Sat afternoon
If Mother Nature wasn't so powerful I might have some words with her; but I know my place ... Seriously, though, the cold front is not moving as quickly as we all thought, meaning the storms won't begin until a bit later. I had always been saying the storms wouldn't happen until the evening, but I'm now saying later in the evening. Again, S MD will see the bulk of the storms even later. Although, some storm cells in N VA have popped up, and a cell or two did briefly form in S MD. But, the main line of storms will be later.
Keep an eye on the sky. If you can hear the thunder, you can be hit by lightning.
With the cold front moving in from the Great Lakes later today, we have a great risk for storms later this evening into Sunday. The front should stall in PA, giving us rain and storms Sunday into Monday, then moving out Tuesday allowing another cold front to come in Wednesday from the west; more unstable weather. The bottom line ... cooler temps, but rain from now through next week.
TIMING: The rain could start in W MD and central MD late this afternoon, with storm activity early this evening in the same locales.Those in S MD will see rain and storms a few hours later than the rest of the state. Storm activity will last, off and on, through Sunday evening.
THREATS: The main threats are wind and hail, especially overnight and into Sunday afternoon. If this current cloud cover lingers long into the afternoon, the severity of the storms will be decreased.
I will have another update later today as needed. Follow me on Twitter (@wxmanmd) for storms updates and weather tidbits.
