Yeah that looks more positivity tilted than the 12Z

46.4/46.1... This is why I have a WSW and you dont.

All I am concerned with is where the SW in located and where it goes negative (if it does)

Thank you Mods for everything you do and everything you have to put up with.

They do... It is the Kuchera ratio

It is not the surface I am worried about.

it is way positive at 48 compared to 54@6Z

it is all about it going negative tilt now

I don't think I am liking the change... I could be wrong

The ICON is too late with the negative tilt

and as for the 3K... the meat of the storm is after the end of it run

THIS IS OUR STORM!!!

I do not know how it is a step back for Baltimore north.

Yeah... just need it to go negative a couple hours earlier

Looks better to me on the H5@18

The NAM at H5@15 is more robust out west

I think someone needs a timeout

Give me one good thing you have brought to the forum... other than the increased whining... have you bought any good analysis?

Yea. I don’t why people need to be negative. If they don’t think it is not going to happen then why be here. Just to say you were right?

I found his updated NWS forecast

I see Gray Hat is in a trolling mood like usual.

We are bring this one home!!!

Reminds me of Storm 2 in 2010

You are missing they have no idea what is going to happen so they are covering everything.
