osfan24 Posted October 29, 2021 Share Posted October 29, 2021 The coastal flooding is obviously very significant and could potentially be very costly but the rest of this storm is very meh. Rainfall will probably end up around an inch and the winds look like they will top out at gusts in the low 40's. Radar looks like the back edge, except for some isolated pockets, isn't all that far away. 1 Link to comment Share on other sites More sharing options...

Radar looks like the back edge, except for some isolated pockets, isn't all that far away. But the heaviest convective elements have yet to move through the areas on the east side of the Potomac, and the HRRR (and other CAMs) have been suggesting redevelopment which will keep the rain going for a while, and the latest HRRR runs suggest another 1-2 inches for some.

It just looks rather sporadic once you get past Southern MD. I guess it really depends on what happens in that area northeast of Richmond that seems to be trying to expand a bit. I'm curious if a new line is going to form or if the line northwest of DC is the one shown on most models as being the main show. The NAM looked really impressive about 24 hours ago but definitely looked less impressive since then. Link to comment Share on other sites More sharing options...

Yeah, that's definitely the story of this storm so far. Hope it doesn't rise too much higher for those folks. I wonder what the highest tides were during Isabel. I remember some areas in Baltimore County were basically wiped out. Link to comment Share on other sites More sharing options...

MN Transplant Posted October 29, 2021 Share Posted October 29, 2021 The thin line doesn’t have any wind punch to it. I’m guessing any chance to mix down is going to have to happen ahead of it. Amazing how October was bone dry until the final week, and will now go into the books as above normal in many spots. Soaked out there. 1 Link to comment Share on other sites More sharing options...

The NAM looked really impressive about 24 hours ago but definitely looked less impressive since then. There is a large area of heavy rain with convective elements now affecting the areas just east of DC moving north into Howard Co and the Baltimore area, with more redevelopment further south. I'm not saying that it's going to be a widespread 4-5" event or anything like that, but the totals are really going to add up over the next few hours. 2 Link to comment Share on other sites More sharing options...
