18z 4k NAM shows about an 8 hour period of nearly non-stop thunderstorms from about 12z-21z. 

the 3K you mean.  it's always a bit overzealous in that dept-it had  alot of that for today and all we got were some popcorn showers here and here...

Yes the 3k, not even in the same ballpark in terms of forecasted storm coverage.

Jesus.

Just in time for the morning commute.

BTW, following the severe threat down South today. Seems that the HRRR is having major issues because of a few down radar sites. Seems as though that model analyzes what's currently going on based on radar and then inputs that into the next run, so I don't know if that will impact the HRRR for our region later tonight.

Parts of the Southeast being considered for an upgrade to high risk, interesting that they have mentioned a dry bias on the modeling. Hopefully that lends itself to an epic soaker up here downstream.

the key to the soaker up here is that big area of convection that rides up NJ and off the shoreline a bit...where that ends up will be the areas with the rainfall jackpot....

12z GFS says congrats Buffalo.  Quick round of rain for us and that's it...does give us an inch or so in a short period of time.

and CMC has the same dryslot b/w 2 maxes....

 

The GFS has an inch + in most areas and it's a much lower resolution than the RGEM and NAM.

It's certainly possible that we do get a bit of shaft between waves, but it's going to be nearly impossible to predict exactly where that's going to occur given the convective nature of the precip.

I'd tend to agree on a surprise either way-big dryslot or a deluge.

Glad to see the UKMET more than doubled it's amounts from 00z and the uniformity and intensity of the precip shield. Remember that a global model probably isn't going to see where the most training occurs with this convection.
