A little perplexed at the consistency of the track between models this far out.

It may consistent but I am willing it will all change. I got 50 cents . Any takers ?

Do you have two tens for a five?

From a snow map perspective, this is better than prior runs.

Canadian ens also a tad better

Canadian model more snow friendly with Maine because they want Maine back.  They're hoping that through the weather model, residents will want to secede from the U.S.  🤪

Good sleeping material from Sterling. 

joys of living in southern mid Atlantic.

 

LONG TERM /SATURDAY THROUGH WEDNESDAY/...
Spotty shower chances and mild temperatures this
weekend before more widespread precipitation chances arrive with an
area of low pressure early next week.

High pressure will remain anchored over the western Atlantic with a
weakened cold front set to cross the region Saturday before stalling
to the south across central/southern VA Sunday. The highest
opportunity for rain areawide looks to be on Saturday afternoon when
the best forcing is overhead. Even with that said, no washouts are
expected with fairly light precipitation amounts and overall
spotty/scattered coverage. Outside of the rain chances will come the
extra clouds and very warm temperatures. Some locations may near
record territory Saturday afternoon pending any breaks in the cloud
cover. Highs for most will push into the low to mid 60s with 50s
over the mountains. Temperatures will cool back into the mid to
upper 50s and low 60s under northwesterly flow in the wake of the
front Sunday. Cloud cover Sunday will linger especially over the
southern 2/3rds of the forecast area with a few breaks in the clouds
further north as brief high pressure settle.

A much more impactful system looks to arrive on Monday and Tuesday
of next week. An area of low pressure will trek from the southern
Plains into the Tennessee River Valley and Carolinas during the
aforementioned timeframe. 12Z deterministic guidance continues to
show subtle differences in regards to the overall timing, track, and
precipitation type with this system based upon potential
interactions between the northern/southern stream. The 12z GFS/GEM
tends to be warmer with low pressure up across central/eastern VA
while the 12z ECWMF is a bit colder and further south. With that
said, confidence remain low in regards to the scope of wintry
precipitation especially in areas east of the Allegheny Front where
overrunning could occur.

Current thinking is that the Allegheny Front will see wintry impacts
with a mainly rain event further east toward the Blue Ridge and
Baltimore/Washington DC area. After several dry days, flooding does
not appear to be a concern, but given saturated soils and above
normal streamflows a few isolated/localized issues cannot be ruled
out especially east of the Blue Ridge. The highest probabilities for
1" of rainfall look to sit between 30 to 35 percent especially in
areas along the I-95 corridor. Of course, this is subject to change
based upon the track and overall intensity of the low Monday into
Tuesday AM.

12z guidance continues to illustrate a quick hitting low pressure
system that is into the area Monday and out of the region Tuesday.
Upslope snow showers will likely linger it`s wake through the middle
part of the workweek for areas west of the Allegheny Front. This is
due part to increased northwest flow and an additional front that
looks to push south from the Great Lakes region Tuesday into
Wednesday. Temperatures will fall back to average to slightly below
average during this time.

There is that shift north I am so used to in the past 10 years.  We used to regularly get snow.

All eyes then focus on the Tuesday forecast with notable shifts to
the 12Z operational and ensemble solutions regarding the potential
formation of a New England coastal low. Previous runs have kept this
system over the Mid Atlantic region and not overly intense. Current
guidance suggest more of a well developed surface low further to the
north, potentially along the New England coastline with impressive
cyclogenesis. Guidance produces significant QPF with the exception
of the fast Euro solution.

In any case however, there remains significant difference in the
ensemble solutions as to the location of potential snowfall. In any
event, this will need to be monitored (during a period of high
astronomical tides) as model solutions will continue to change over
the upcoming weekend and into early next week. Before we get to that
point, a prolonged period of above normal temperatures and gradual
snowmelt will continue.

Oh boy.  What happened to the northern system?  Southern looks very close to 12z

Energy coming through the western ridge is different too.

Geez, just looking at the 500mb GFS v Euro and they are not alike.

At the sfc they spit out roughly the same looking storm.

MJ's spaghetti have shown how different southern vs northern has been. Southern was pretty close together, northern been all over the place.

That trend is really only one direction... chance it starts to correct back east? The piece of energy at the 4 corners has accelerated way ahead to texas. The northern stream of energy has flip flopped back and forth.

Southern jet showing great consistency and should bring the moisture either way. The northern jet just can't figure out what it want's to do yet.

Hopefully, I just pulled a reference to 2010 in the latter storm thread.

Damn straight buddy! 
Throw a dart at this point. Somewhere within 500 miles north to south. 😂
