While we wait in breathless anticipation for the NAMS….not sure if it was posted on here earlier, but here is @Ellinwood map for this storm.
He is a respected Met in the Mid Atlantic thread.
They are most useful for pattern recognition and are beneficial to get a good handle a week or 2 out instead of watching wild swings on Op runs.
I like to see ensemble snow maps to track long range pattern potential.
In the short term, when an ensemble locks in like EPS has over the last 24 hours, it usually is on the right track with the probable outcome.
Give me an inch of precip like the 18z Euro shows & I like the Harrisburg area’s chances to score Warning level snow with this low track & cold enough air in place.
If the precip stays moderate to heavy, it should stay mostly snow in my opinion based on my experiences over the years.
