If this is correct that band indicates the storm has gone Negative and pushed to the band back NW so much so the Cape Hatt is dry slotting....lol a full fledged EC snowstorm....

 

While I could see precip being bullish for sure, can the RAP's track really be THAT far off?  I honestly haven't paid much attention to it.

From the NOAA site  :whistle:

 

"When accurate and timely weather modeling is needed most, the new Rapid Refresh model delivers," said Louis Uccellini, Ph.D., director, NOAA's National Centers for Environmental Prediction, a part of NOAA's National Weather Service. "This new tool ensures that forecasts are the best they can be by using the latest science and computer techniques in an effort to create a more Weather-Ready Nation."

Looking at PSU's obs from Manchester earlier this evening it is interesting, in a depressing way, what an extra 400-450ft in elevation can mean when it comes to these marginal events. While he reported 3+ inches, only 10 miles up the road in Hanover, we have zilch. Went to bed at 8:30 last night with it still raining with the occasional icy rain drop mixed in while he had been reporting sn+ for quite awhile by then.

No surprises with the 06Z NAM. Slightly SE as well as a touch more consolidated with the low compared to the 00Z. The run does pull the better rates closer to the coast where another 50 miles would potentially put them into a moderate event if temps cooperate.

 

Edit: No major changes with the 06Z GFS compared to the 00Z.

I can confirm. Drove to pa last night after the snow. Going northeast to York good snow along the higher terrain through lineboro and Glenn rock (800-1000 ft). Then when I came down into York suddenly just wet. No snow the rest of the way up to pine grove just rain

Except on ridges.

Total elevation event.  This is why even in larger events we seem to  jackpot sometimes due to ratios being better.  Just an amazing micro climate around the Mason Dixon line due to elevation.

 Yep, for the V day storm I drove up a hill that was only 300ft tall they had 2 inches to my dusting at 50 ft. Amazing. It doesn't take much.
