January 22-23 Storm Threat


Ralph Wiggum

Recommended Posts

We have most of the global models trending towards a big hit in our area. The hi Res short range are screaming major hit. The Ukie came North and is a big hit. I know the Euro is the King, but I'm not sure it is on the same page right now with other guidance. Could be the one model that actually is handling this the best so who knows. After last January, I don't tend to trust the Euro when its by itself as much as I used to in the past.

Euro and Canadian are a lot alike, no?

maybe things have changed, but i believe the Euro verifies best at this range out of all models. im open to contradictory information

 

 

I think I heard the same  in regards to the global models.  From here on I am going to concentrate on the RGEM.

GGEM qpf is misleading. Surface and upper features suggest otherwise IMO. The surface low really tries to stick back near the coast on the GGEM. I call it a near or partial capture, but that is debatable I suppose. Euro looks to do the center jump thing. I think the deep convection out over the Gulf Stream is really wreaking havoc on the globals models. They don't know where to place the slp. Some have 3 or 4 centers. I'm leaning towards the higher resolution models at this range. Not hugging them, but using them for better guidance and handling of key features.

Euro has multiple lows...i know the canadian has gone that route in other runs, i have to look at it again.  Interestingly, qpf down across the board on the Euro, I'm wondering if the result of having multiple lows is that a lot of the best moisture is being robbed offshore.

Could very well be. Whether it is right or wrong, I don't think we truly resolve this 100% until Saturday. Its like a see-saw....the models are going to struggle with that convective feature. As u said could rob moisture and jump the low center away in a hurry or the convection is a non factor and the slp hangs back closer to the coast. Difference between a SECS and a HECS IMO.

The Euro is almost always the driest model out there and yes I agree with Ian that the Euro usually backs off significantly on qpf as it gets closer in to an event.

 

As long as the general track is the same then I think we're fine.  I also agree that we are actually in the better wheelhouse now of the hi-res models versus globals like the Euro.  We are like 35 hours out now or less.

I think at least for PHL and immediate burbs, we are good for a MECS.  I would bet against a HECS, I just think the very best stuff stays south, but 15 inches or so definitely on the table.

Other models also have had multiple lows, is this from poor capture issues...?

Several factors causing guidance to struggle with slp and number of lows. Confluence attempting to halt Northward progress, ridge flattening out West trying to kick everything East, NAO going neutral trying to fight confluence and pull North, convection over gulf stream trying to jump slp center, low trying to occlude and stay tucked near coast. Its like a balancing act. Still think we in SE PA are in a good spot. Not sure the somber mood past hour based on the Euro op?

Thanks Ralph...I'm okay with things as they stand now since all we have to do is get underneath mesoscale banding and I'd like the wind to verify...

His comment to DT it's great....in the MA forum...lol.  Dt wanted to know why RIC isn't under a blizzard watch when NYC was since nyc was only getting 3-6 inches of snow and irishbri told dt that snow accumlation isnt a requirement for a blizzard. 

 

I enjoyed this since dt is all over people for their errors...and he should know that

I think the somber mood is based on the ggem and euro.  That precip gradient is getting WAY too close for comfort (and down right inappropriate for some).

If the NAM stays the course we make out, if the slp has issues capturing and coming north like globals are showing quite a few in this forum might be hoping to bust high just to make it to Mount Holly's current minimums.

I take it you are a stones throw from the oxford valley mall.....correct.  We are in a good spot as long as the wind verifies who cares if we only see a foot of snow.  If it's as intense as it could be, it wont matter and you'll love it.

Can't find it. What I did find however are people in MA jumping off bridges due to the North trend. Yet in NYC they are jumping off bridges due to South trend. Puts us in a good spot really! :-D

It may have been deleted....ill see if i can find it

 

EDIT: begins at post#1332 in the old thread...they started a new one look for thread #3

I think if you blended all the models you'd get a 8-14" for Philly...with isolated more...There is going to be a lot of mesoscale banding with this one....

 

OT; Does anyone want to storm chase with me" I need an answer ASAP. Looking for someone to split hotel/motel costs. I'd pay for gas unless you drive then I'd split. PM me. I'd leave tomorrow morning like 11am ish. PM me !

Where u thinking of heading? I'm actually fairly content where I'm at but just curious as to where you see 'ground zero'?

I really think you're in pretty good shape currently...location.

North trend?  every model for 6 days has slammed the MA with no exceptions.  I've never seen a storm more locked into an area.
