3/11-3/12 Winter Storm

Not that anyone cares, but the upper level jet divergence is excellent on the GFS/NAM (aids in rising motion for precip)....but our 500mb / 850mb waves aren't quite sharp enough to ignite more precip.  Upper right panel shows the Carolinas in the right entrance region of the jet streak off the mid atlantic coast (=divergence aloft)

The CMC was actually a step in the right direction for Sunday as it increased the snow coverage, it is starting to strengthen the first piece of of this mess  as it gets to the SC coast....Nam also has a similar look...

00Z last night

12Z today

Just makes it more painful, this setup wasn't that far away from being a nice 2-4" overrunning event.

I have no good Euro access anymore.  Wave looks pretty anemic.  Anybody got a clown map?

From Charlotte Channel 3 futurecast. Is this Nam heavy?

Yeah they're both based on the WRF. It's WRF-NMM for NAM and WRF-ARW for the RPM which is the futurecast or whatever that most weather stations use. I think the RPM only goes out to 24 hours though. I don't know if the stations run it longer in house or if they just use NAM output after that.
