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

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.

 

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.

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

 

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.

If this event beats the 14" my backyard got in jan 2011 (and probably march 93 as well based on KU maps), I'll be incredibly thrilled, especially if tssn is in the mix. But I don't expect more than 10" so we'll see.

Ian's reply was good.  Better to have it on your side. 

 

Shave precip by a 1/3, give it a 7:1 ratio, and we still are sitting at an 8-10" storm on the NAM in DC.  That's pretty good.

I think these snow maps have been historically terrible. Wouldn't worry about them

 

Hey, you're not snowholed ok. You cannot imagine the desperation and despair I'm feeling right now. I'm rooting for fire balls to drop out of the sky instead of snow and burn the whole place down. everything. poof
