If the meso models are right, cause the rgem has the same. The screw zone may be lessened for this area do to the coastal forming off nc/va coast instead of nj. Nam has .15-.2 for the region as well as the 6z rgem. 

 

Yes, at this point, the later the better for secondary redevelopment. The flow obviously won't allow for something closer to the coast so we might as well hope for a later/weaker transfer. Let's see how the GFS goes.

:lmao:

The conshy 1.6 was a conversion error. He measured

Your's not in Qpf, but FLAKES*

Anyhow, still sticking with my coating-2"

For most the area except Delmarva.

Although, according to the mid-ATL people,

Some places in MD got up 4-4" from that clipper last night. High ratios wildcard?

Seem to only affect the mobile skin and tap-a-talk. )

Where is the global superjet to help?!?!

 

I just love weakening front-running vort maxes in a semi-progressive flow. If we could get any type of fronto forcing in the mid levels, we would have no problem pulling off an advisory event. I haven't checked the soundings on the new GFS but it's almost like, "why bother?"

Yeah Its a shame to waste that 850 temp gradient

Isn't this still going to be advisory-level for some?

The HWO from early this morning mentioned that totals look to be in the 2-3" range, so that should generate a WWA for us unless their thinking/guidance changes...

Possibly...advisory fatigue....timing, if its slow enough to only be on back end of evening commute...well advertised event already, so not like a later issuance catches anyone by surprise...avoid issuing only to retract in case models go last minute totally dry/all snirga....or it just to make weenies more grateful if one is issued

12z euro brought up qpf compared to 0z, everyone over .1

I don't think if you'd showed 10 mets just the 500mb and 850 mb progs for tomorrow evening that you'd get many less than one inch forecasts (south).  On the other hand I know one of the guys who would go close to a 10:1 ratio for domani.  He is big on strong winds fracturing the snow crystals in dendritic growth zones and there will be plenty wind aloft tomorrow.  But if this ends up being a 1-3" event, I dont know if there is enough there to support or disprove the thoughts. Its easier to fluff when the accums are light. ----------->  (I did order a Captain Obvious tee shirt.)

C-1" above 195 in NJ, 1-3" south of a AC-Dover line, 1-2 everywhere else?

 

Yeah, looks like the depiction on the models shows dry air trying to wedge southwestward from New England. Maybe lowest numbers from ABE/TTN on northeast with 1-2 most other places. I think a shore location south of ACY could  squeeze out 3" if all the planets align. :)
