The Weekend Rule? Saturday 2/17 - The Icon Storm

[stormtracker]

Onset still between 10-1

[stormtracker]

Still the same, but withOUT that ridiculous heavy stripe that was over DC and like mont county...so it will be *drier* for that like 15 mile corridor

[stormtracker]

Looks like a hold with the above posted caveat

 

[Terpeast]

Sfc right at freezing at IAD

[stormtracker]

4-6 for everyone north of southern MD and that includes DC with some wiggle room to the south.  These are with the wonky ass SV maps, so use with caution

I’m expecting temps to plummet as soon as I hear the thunder.

A dewpoint of 12 says the bottom falls out

Going by QPF it's 0.45" for both IAD and DCA with a local max of 0.58" near Frederick

Just go with 0-8 with a possibility of 10

That’s an Alaska forecast. If you’ve never looked at one, do. They are amazing

i've lowered my bar from 3" to 2". I pray I don't have to lower it any further

only in this area can we have 850 temps at -6  to -8 and worry about temps

Get used to it. Boundary is warming faster than other levels

DCA falls to 33 at 2 am.  It would be nice to get some accumulation here before that. 

I don't think DC proper reaches freezing at all, but outside of the beltway good chance of that. Either way, if we're lucky enough to get sustained rates for more than two hours, we should be good

Saw that mentioned in a wx disco two days ago. I haven't experienced it here in well over a decade, but here's hoping.

Difference for MBY between 3k NAM and gfs is like 0.05” of precip? 

[Solution Man]

Radar out west is money

In DC I wouldn't either... it will likely be history if you wake up after 9am.

[Imgoinhungry]

What time should i set my alarm to get up and take a walk in two inch per hour snowfall?

I'm fine with that, I'll be up tonight.

For me, it's 0.5 vs. 0.3. Big difference. Either way, 3-5" is a reasonable forecast, or 2-4" if being conservative.

I'm gonna try 1am. Maybe a little earlier where you are at. It's a 3-hour storm

For all the DC yappin' gone off the rails...just thought I'd post up this ditty. Bears reminding based on where you are.

"The highest natural elevation in the District is 409 feet (125 m) above sea level at Fort Reno Park in upper northwest Washington. The lowest point is sea level at the Potomac River. The geographic center of Washington is near the intersection of 4th and L Streets NW."

Topographic map below. DC is a combo of appalachian ridge and plains. Like a bowl, edges are high, middle part low. Mt parents and grandparents said the mall was swampy at one time. I saw an old pic of cows grazing on the WH lawn! Crazy stuff. NW is large areas of high elevation. SE is a staircase that keeps going up and most of the streets are hills in all directions. My neighbors can sit on their front porch and see the Cathedral in NW clear as a bell. On Howard road SE you have a clear site line to the monument like its a mile away. Wild.

We now return to your regularly scheduled snow channel...
