update Saturday morning
My CoCoRaHS rain gauge measured 3.38 inches of rainfall for Friday alone. Wow!
Enjoy the rest of the weekend as it should be cool yet mainly sunny. No rain.
Looks like my forecast was good, but the timing and location of the Low was off a bit. The Low is a bit more to the North, so DE and NJ coasts are receiving the brunt of the wind and rain, yet Central MD is receiving a good amount of rainfall. By late tonight and tomorrow all this should be over.
The question is: should this have been a named storm?
A look at the recent model data shows the non-tropical system currently off the coast will be heading our way. This is not a tropical system and will not become one, but it is acting like one, complete with wind and large amounts of rain.
The data shows the system heading directly over the Potomac Thursday morning into Friday morning. What this means is the chance for rain accumulations of 2 inches or more and quite windy conditions. Those along the Delmarva and Northern Harford county and to the North will most likely see accumulated rains in the 4 inches or so. Winds that far from the center over the Potomac should not be felt.
I will keep you posted, but as far as timing, the system is moving from the East in a WNW fashion, so those closest the coast and North will feel it longer then those in the South (Potomac), but it will begin there sooner. So, the timing, depending on your location, is early Thursday morning into late afternoon Friday.
I would not be surprised if there are flood watches/warnings issued.
