my hunch is that thing is gonna have localized 12 to 15 inch totals for some lucky folks....thats a bada## piece of energy!! the radar is totally convective....dont worry im certainly not thinking those totals for mby but whoever gets in on the primo dynamics is not going to be able to wave to their neighbors across the street for a few hours lol

There's not a bats chance in hell.

GFS trying to make the followup system a bit more interesting than 2/18. Has another miller B signal on 2/19

Yea 2/19 has been off and on with guidance..most likely be a late bloomer with Maine having the best chance for anything

With regards to the 2/18 system, the south coast is likely toast because of the BL..i.e. BOX map looks good.

Yeah with temps even at 925C too warm..however the precip is reallly confined to NE MA and especially Maine.

This all makes sense in the pattern. The pattern temporarily lifting out but still enough push for tomorrow's system. A little less push (further north) for the next one in terms of track.

really like the lowell area for this event .. def a lock for 3", and if everything breaks right could be 6"-7" .. the meso models will be interesting later on this afternoon . gotta be impressed with the obs in midwest this morning / the convective nature of this system.

I'm supposed to be there til 5. I hope they pull the plug on tomorrow...at least afternoon classes.

They're all SREF members so they're both pretty much weenieish. Usually the ARW ones are overamped/overjuiced. IIRC those are the SREF members that are too moist. Chris would remember.

 

It is the ARW members that have been incorrectly initialized with the GFS since Dec 2012. It would be cleared up until the next upgrade. The result has been ARW members that are too moist, since they are supposed to be initialized with the RAP.

I thought I remember reading verification on ARW was better, but I could be wrong.

I haven't seen the verification scores for the new (post ETA/RSM) SREFs so you may be right, but the ongoing joke around here has been to deselect the ARW members on the plume site.

This was on the upgrade announcement too (maybe you saw it already)...

B) replace inadvertent use of global initial conditions (too

moist) with use of Rapid Refresh (RAP) for ARW members to

reduce the surface wet and cold biases reported by NCEP’s Storm

Prediction Center (SPC) and other users
