Firstly the bsr looks excellent with an opportunity at phasing the PAC and artic jets
I notice an hp in the pna region which leans me to believe a +pna will be available BSR

A continued interesting looks extends from the 21st into the 23rd matching the soi delta dates
 A lot of Gom action 22-23rd continues during thread dates   This post has been edited by PoconoSnow: Jan 10 2018, 08:14 PM -------------------- Ensemble Primer use only for real forecasting :)

EAR
Shows a barely missed phase between to pieces  Euro has the same disturbancecon the 17th which would match a short correlation to the 20th but a 6d lead to the 23rd  For thread opening purposes I'm going to use these systems to correlate rather than revert back to the systems in Japan yesterday and today. Their look compared more favorably to what I see in the bsr anyway SOID Southern oscillation index delta displays a large 4 day drop centered on the night of the 24th There is a chance a stsytem may follow the heels of this thread. We just have to wait and see and adjust or open a new threat  RRWT averaged to 57 days and spanning 3 days to fit thread duration

It kind of busts my (according to rtcemc, ever evolving) LR winter outlook, I can't find anything to not like about this time pd. Might have to peck at this during Rooster shift, but weekend system has questions still, so maybe not quite yet. |

Statistical
Deterministics Gfs has shown a storm between the 21st and 23rd for quite a few cycles now, some suppressed some cutterish. Here is latests 18z  Euro out to the 20th has a digging Midwest trof  Probalistics Gefs on the 22nd shows a non washed out mean which is very interesting

Well, UT, maybe it will show 250 miles to the northwest and help keep your call intact

I know Earth 3D weather att is showing warm (50s - 60) in the Dover DE area so we will be keeping an eye on the changes as there will be many.

On a side note, sadly, the 6-20 day from there was discontinued a few days ago Darn The one thing I do notice in the 5d map you posted shoes the propensity for a +pna and some high latitude blocking. Currently esrl and ensembles have our pna going negative. So we wait and see:) I enjoy opening long range threads without the reliance of models deterministic or probalistics. It adds to the challenge and if you get a hang for it the dates become even more accurate than models believe it or not. Ofm is an excellent tool This post has been edited by PoconoSnow: Jan 10 2018, 09:57 PM -------------------- Ensemble Primer use only for real forecasting :)
