Central PA - Winter 2020/2021 Part 2

Future radar for my location has it snowing here until about 4pm. Then the usual drying out that rides up the I-81 corridor commences. Which begs a question from me.

What causes that feature to take place so often? We many times dry out before other areas of central, eastern, and northeastern PA. It'll mostly be finished here but out to the west of the Susquehanna, snow will continue for a couple to a few hours.

Here in Carlisle at 10:00am it is snowing heavily and has been heavy for the past 30 minutes.  After almost a 30 minute slowdown it suddenly picked back up again.  I just measured an additional 0.8" of snow during the past hour giving me a storm total of 1.8".  The temp is up to 28.8 degrees.  As I type this it is almost snowing the heaviest of the storm thus far.  Easily over an inch per hour rate.  Maybe the NAM will be wrong for me?  Biggest flakes so far also.

Gotta be elevation dynamics, no? @MAG5035 is there any scientific meteorology behind this type of phenomenon?

I honestly didn't expect this. We have great rates in Harrisburg. And the reports coming from the guys west of us give me hope. My temp dropped 3 degrees since this started

I finally went out and just measured about 2.25". You measure lately? The rate + flake size the last 45 minutes means business.

I thought there was a 50/50 chance, best of the year, yesterday as the day went on and the entire model set kept increasing, especially when the HRRR came started to come strong.

Here in Carlisle at 11:00am it is currently snowing heavily, though not quite as heavy as an hour ago.  There were a few lulls during this past hour as well.  I picked up an additional 0.5" of snow, giving me a storm total of 2.3".  The temperature has risen a little more and is now at 30.0.  Winds are light.  Looks like I'm going to reach 3" at the end which will just put me over the 30" mark for the season.
