Sally is now considered a Post Tropical Cyclone with no more advisories from the National Hurricane Center. However it still has an impressive circulation on the satellite loop, with plenty of rain moving well north of the Low in Georgia.
That rain is just now reaching southern Maryland. Some of the norther edge is expected in metro Baltimore tonight, but the very heavy rain will stay to the south. After looking at the latest radar simulation, we shift back to the Gulf of Mexico for what could be the next and last ‘named’ storm. After Wilfred, we go to the Greek Alphabet.
Afternoon Weather Set Up
The remnant Low of Sally is in southern Georgia, but the rain has shifted well to the north. A very impressive feeder band is pulling a thin line of heavy rain in from the Gulf of Mexico, across northern Florida, and into South Carolina. Some severe weather is still developing in this area, even though this is no longer an official tropical system.
Sally Satellite Loop
This visible loop shows the surface circulation well, along with that feeder band. The northern edge of the clouds has spread across our region. Look to the top edge and see the cirrus cloud fringe across New York and Ohio. If this storm was still over water, it would have a lot of support aloft to have keep it going. But this is dislodged from the surface Low now.
This radar loop matches the same image shows off that feeder band I mentioned above. It also highlights the bulk of rain now reaching into southern Maryland.

The NAM 3 Km forecast is trying to bring in light rain across central Maryland later this afternoon and evening. This may be a bit early and overdone. But light rain should try to arrive this evening near Baltimore.
The moderate to heavy rain will clip southern Maryland and linger into the morning Friday. It will clear out in the afternoon.

My ‘bonus’ daughter made this map of Maryland a few years ago. We brought it back for needed positivity. Now on her pick of tanks, and this cool Maryland T for men or women.
