Yeah this morning was okay but a tad underwhelming

IIRC, advisory is 50% confidence to meet or exceed 2".

Not sure if this was posted- I didn't see it so here is the Euro AI. Better than the last 2 runs

They’ve actually juiced up but were a degree or two to warm and we waste a lot to rain

Afternoon Euro-AI now gives I-70 and points north a 10% chance of 6"+

That model is so bad!

We're officially hugging the 3k Nam.

[Alfoman]

Sheesh that WAA really screws the city and surrounding areas 

[yoda]

Should be an interesting AFD read in a few

Let’s ride. I’ll crash and burn with it 

[WEATHER53]

I mentioned in the obs disc that models are still in the B mode and this isn’t a B.   WWA will be placed for DC soon and we have low pressure actually along the coast and the cold air is mostly coming counter clockwise from Lows up to our north with assistance from a high around Nebraska.  The change in any evolution of the outcome Won’t  be a disappointment this time.  We’ve cleared now and should get some good radiation before clouds take over 

[WxUSAF]

omg that looks awful.  From out to sea to too far west and it's rain.

It isn’t really the surface temps that are the problem on the NAM. 33-35 is ok at night with decent rates. But there’s a really annoying warm nose at 950mb.

That doesn't look like a WxRisk map. There are no intersecting lines

That's not far off the deck at all. Higher elevations in Howard, Carroll and Baltimore counties should be able to overcome it...hopefully.

Were you summoned by @WxUSAFsaying warm nose?  (BTW what went into choosing that name? Sarcastic irony?)
