Euro just keeps the precip a strung out mess.. there is a low, but way offshore and not a good surface reflection...

120 looks interesting out west and in the plains.. nice +PNA building, precip into TX, OK.. although, im sure thats for a diff thread...

it goes snow to ice to maybe rain then ice to snow.... interior is fine....trof went negative to quickly so you get a low track from nc to about 75 miles east of acy

Not bad at this range Tom, interesting how different the Euro and GFS are about this threat and its timing (aka right after the first storm on the GFS to 150 on the Euro)

Doubt its rain..504 thicknesses over OH and 2M temps are very cold. It's very close to being a big snowstorm

Western ridge is a bit far west, and there's still some warm air and ridging in the SE . Of course most other models have everything too far east.

But how serious is this ice storm threat? .25 to .50 is not to bad anything over .75 is serious. I agree nothing is worse than 1 inch of ice and a cold front blowing through with no power.. Everyone has forgotten about the sleet storm of 2007 in the same general area that is being discussed - a storm that was not forecasted to be sleet . Somebody better wake up and the smell the roses. Instead of discussing the chances of coastals and snow, lets discuss the chances of a serious ice storm from ABE to Hazelton. Frankly, I am tired of hearing about the chances of lows developing along the coast and snow chances in NYC when the real threat is an ice storm in the LV to Scranton. Thanks

I would say .25-.5 of ice is serious, .75 would be near-crippling for us here in LV.

With this 18-29th frame becoming a 50-50 and helping re-establish the -NAO 9somewhat east based on this run), and a MJO wave forecasted to be in an amplified Phase 7, and a +PNA ridge AND a PV dropping in, this time frame has HUGE potential written all over it. Maybe a thread for this threat/time period John?

That is a good idea.

Yeah, you can go ahead and start it if you'd like. For the record, I think it has potential, but I wouldn't call it huge. The blocking is east based and doesn't really stretch very far west towards Greenland.

If you believe the ECMWF ensemble means after 6 days..the blocking actually semi-breaks down again. The saving grace is the big +PNA ridge..which is supported by the MJO. But the problem is that without the blocking to help force the amplification of energy underneath, it becomes a cold and dry pattern with a big ridge out west and a big trough in the east.

For next weekend's storm, we need the energy come out of the SW slower, so we can give more the time for the -NAO block to mature. Otherwise, it might become a wintry mess.

we need it to be slightly flatter than the euro's solution. our best hope is a moderate event along the wave that rides the front

the pattern in no way supports a big storm
