Good evening Mid Atlantic! Active day for some as a system begins its advance into the area.
Friday will bring about more activity for some along the I-95 and 81 corridors as that same system pushed more eastward. The severity of it hinges on what happens in the morning hours though. If we see cloud cover or, as some models suggest, a morning line of showers across parts of the region, then we will see a dulled effect on what happens in the afternoon. On the other hand, if we see less cloud cover and rainfall, the atmosphere will have more time to charge up and give us some more severe weather.
TIMING: This brings back what was mentioned above; we may see some AM rainfall across parts of the area. That would be mid-morning.
As for the bigger stuff, we are presently thinking around a kickoff of 3pm in the afternoon going into the night ending around 10.
HAZARDS: Right now it seems like our biggest risks are damaging winds and hail in storms that go severe. One thing that is also a fear is the possibility of storms beginning to “train” and dump large amounts of rainfall leading to a flooding threat. Now your probably thinking, “Tornadoes?” This risk is lower but still there. The possibility exists for a few warnings because of rotation on radar and a few spin ups are possible, but its not the biggest of the factors we are watching at all. We will continue to monitor this for you, check in with your local NWS Office, the NOAA NWS Storm Prediction Center, Maryland Weather Center, and local Foot’s Forecast zones for details locally.
