I think in terms of surge they want it to swing out and come in across LI like a few of the earlier runs today tried to do. That would push more water up.

Bob Chill Posted October 28, 2012 Share Posted October 28, 2012 Sheesh. GFS is quite a hit. 952 @ LF smack dab in the middle of NJ then drifts over philly @ 956 and then floats along the mason dixon and then parks over the WV panhandle until it gets tired. Good god it's going to be windy and WET. Link to comment Share on other sites More sharing options...

Bob Chill Posted October 28, 2012 Share Posted October 28, 2012 right around here is when the whole megalopolis goes dark This is a damn funny post. I laughed. It's comical on so many levels...and then reality sets in because it's real. Literally millions without power. Literally billions in property damage. And not a damn thing that can be done about it except preparing, staying safe, and helping your neighbors when it's over. Link to comment Share on other sites More sharing options...

EasternUSWX Posted October 28, 2012 Share Posted October 28, 2012 what we lack in top speed we get back in longevity Lack? There is like 90KTS over Baltimore! lol. How much does 900mb transfer down? Guessing gust to 80mph on that map? Link to comment Share on other sites More sharing options...

Bob Chill Posted October 28, 2012 Share Posted October 28, 2012 which raises the question.... how long does it take to return power to several million people? Overall? 2 weeks tops if I had to guess. Vast majority? A week. Individually is the fun part. Why your power is out and where u live means everything. If u live on a rural road where your downed line serves 6 houses then you better hope you have a generator or you'll know exactly how your great grandaddy's granddaddy lived.

capitalweather Posted October 28, 2012 Share Posted October 28, 2012 Re: converting 900 mb winds to surface... I talked to Wes about this earlier and he said - back of the envelope - reduce them by 20 percent (that's assuming little/no instability to mix them down)... When you do the math, the numbers are still ominous! Jason Link to comment Share on other sites More sharing options...

When you do the math, the numbers are still ominous! Jason So lets say the map above Ian posted was 80 kts. I multiply *.8 and get 64 kts. Thats ~75 mph Link to comment Share on other sites More sharing options...
CoastalWx Posted October 28, 2012 Share Posted October 28, 2012 Those soundings did show a very slow temp decrease with height..IOW, it will take some sort of heavy precip drag I think to mix down a lot of it..but it's possible in those areas that get heavy rain.

It may be tricky though because heavier elements of rain may bring it down. Tough to really say. Even up here there is some inversion with strong WAA aloft too.
