Ensembles, extended products & pro forecasters absolutely nailed the pattern change between the 10th & 15th from forecasts several weeks ago….
We are actively already tracking a Winter storm threat in that window.
6z NAM is best case scenario run for southern PA & northern MD.
The Low tracks further southeast off of coast this run, but it still gets heavier rates to southern PA.
The 18z GEFS & 12z EPS are similar with amounts in the LSV.
GEFS gets 5 inches to Harrisburg & York while the EPS gets 4 to these locations.
The GEFS gets the overall snow line about 50 miles further south than the EPS.
I think some people are already drinking at Happy hour?!?
The 18z GFS IMPROVED over 12z…even for the southern tier.
Reminder… Most of us don’t live right on the MD line, lol!
The initial low in the 12z Euro gets to WV before the transfer to the coastal.
Slight improvement over 0z Euro on the Kuchera snow maps for Rouzerville, York & Harrisburg areas.
Good run especially turnpike area on north.
While hopefully feasting on the Euro over my lunch….
Here are the 12z GEFS individual ensemble members,
I count roughly 20 of the 30 members would work for many of us.
I guess my point is that at this range I would rather see the stabilizing of the Euro & GFS, with the risk of whiff on the other models instead of a locking in of models saying “wagons north”.
We still have a long way to go until the Monday night/Tuesday am event.
Later today, the NAM & RGEM wil be in range towards the end of their runs.
The Euro & GFS say we are in the game, so it will be interesting to see where this ends up by Monday.
