Heh. 18z is definitely colder than 12z at the surface and at 850. To be honest, if it went the other way I'd be calling it noise, but since it confirms my biases I'll say its a trend.
Control is hideous though. Better hope we can toss it.
Totally forgot the 18z doesn't go past 90. I was refreshing like a maniac, haha. I'm not smart enough to extrapolate but I'm not seeing any obvious warning signs here. I will say the CAD looks better on the 12z.
fwiw. slightly more west than 06z but there are some big members messing with the mean again (986mb over Hagerstown, for example).
I'd say there are more along the Chesapeake than we'd like but it's more than workable.
It may be the 18z stress but if we get another "where are Bob and Showme" message I'll have to add it to the Bingo board. I don't think we know and we may never know. Been a weird year. Hopefully they show up but if they don't, we do out best without them and hope they are doing well and are healthy wherever they are at.
