March 6th Storm Banter Thread

I realize the clown maps are just that, but can anyone explain totals in FDK?  It has been present on just about every run of the nam for the last 6 cycles.  Not complaining, just curious...12znamsnow_NE036.gif

Frederick is in a valley, and in a marginal storm like this, elevation could have a big role. So that means less snow for Frederick due to lower elevation.

Shutup. I want my foot of snow so I can watch it melt in 28 hours.

I meant they seemed underdone in places like DC etc. 0z was a snow bomb for most everyone and it still had that same look.

I know we are in a valley, but the lower amounts don't correlate to the valley...in fact most of the area in the lighter shading is well elevated.

I'd then say the clown maps don't have enough resolution to properly locate the exact area with less elevation.

Nice to see that 100 wrong NAM pbp posts are ok but ask one question about when it can be trusted and that is called silly

You guys are so uber sensitive .. I dunno.

People like Matt my buddy have confused others into thinking the nam is totally useless when that is incorrect.

I just don't get how people who spend so long here don't understand how models work or the caveats associated with all of them.

That's much better than the last two runs.  Bad news for Rockville though for some unlikely micro reason.

I would love to know the algorithm used to generate this map. What causes the reduced snowfall in Frederick County and that spot in MC?

Fdk is in a shadow sometimes with e-ene flow. You can see the max zone over parrs and fdk is on the lee side. 

 

As far as rockville goes....voodoo hex

We just had a NAM run within 12 hours of storm onset giving the three airports 2" QPF with soundings that support all snow (at least for DCA/IAD, didn't check BWI).  The fact that we aren't all freaking out is a testament to how far the NAM has fallen out of favor amongst the weenie masses.

So you're suggesting we should be freaking out, or that nobody believes the NAM with good reason?

I would like to see the best VVs a bit closer.. they like the NW burbs. But honestly I don't expect to get superbanded the whole storm.. that happens to places like FDK.

 

No one should use the NAM as sole guidance but in this range having it in your camp is certainly a plus.

"this will be the blizzard of 96 of March events. I bet the DC metro area averages more for this storm than the 1993 superstorm. The 1993 superstorm will crush this event in the mountain areas though"

 
Somebody please put Ji back in his cage.

I noticed that on another map yesterday, though it was a bit further north and west.    On the HiRes NAM you can see the initial precip with the NW/SE orientation is lighter N of the Potomac.   Later, the banding sets up on the backside to the NW and SE and leaves that little hole with lighter precip for both stages of the storm.
