Blizzard of 93

CTP has this near term update this evening. .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... Lots of sleet over York and Lanc counties and even working up toward Harriburg and Lebanon, now. This will hold the numbers down, but may make it even more difficult travel-wise since people drive on the sleet and compact it, making it a sheet of ice. That can be tough for the plows to clear. Snow has returned to THV, though as the precip has lightened up. Dry slot expanding a bit as it moves into far srn PA. But, instability still there with thundersnow over Mt Davis (Somerset Co). The dry slot is somewhat concerning as any break of a couple of hours would kill the snow totals if we don`t see the N-S oriented bands set up and move at a turtle-like pace. There are bands over wrn PA (with the thundersnow) and it still looks like we will have the same conditions over central PA for the first half of the night. The lack of seeding over the clouds in the dry slot means it will be a snizzly/freezing drizzle which could fall for those couple of hours from now until 8 or 9 PM. The HRRR has the snow closing in around the dry slot about that time. Will mention --ZR for the next few hrs in the srn mtns/lower susq.

6 inches of snow in Marysville as of a little after 6 pm, but we have now mixed with sleet as well here.

MDT reported 4 inches as of the 5pm daily summary.

Yes, same here in Marysville! The flake size increased in the last 15 minutes and intensity picked up even after the heavy band on radar moved through.

The 18z GFS still buries the LSV despite some mixing for a few hours in parts of the LSV.

It is absolutely dumping snow under this heavy band that is approaching from the south.

4.5 inches of snow in Marysville as of 5 pm ! I love being under a Special Weather Statement and Meso Discussion during a Winter Storm Warning!

The radar is really looking great! Enjoy the snow today everyone! We do not know when the next chance of a major storm will come....it could be weeks, months, or years from now, so please try to take it all in and enjoy!

It’s nice to be starting an event with temps in the 20’s and dew points in the low to mid teens!

Here are the 6z Euro snow maps.

This is the best GFS run yet for the LSV....just wait until @pasnownut sees this run for his backyard!

That’s the best GEFS run yet...wow!

The 0z EPS still looks good and even improved slightly for our southeast crew.

0z Euro still looks good for all of CTP. I added the total precip map to give an idea of where the max zones look to set up this run. It also indicated very little mixing in the LSV this run.

Here is the 0z UKMET...the 0z party continues for CTP.

Oh yes, I want thunder snow too! @MAG5035 or @MillvilleWx or @psuhoffman How is the thunder snow chance looking now?

My favorite part of this...!!! * WHAT...Heavy snow expected. Total snow accumulations of 10 to 20 inches with the highest totals between Harrisburg and Huntingdon.

Boom! 0z GFS 10-1 map & Kuchera ratio

Not just him... All of CTP! Forum wide crowd pleaser!!!

Yes, those 3k NAM snow maps that I just posted on the last page drop the hammer on Harrisburg & all of I-81 in PA. The hourly panels were spectacular.

Yes! That would be awesome! Bring it!

The 3k NAM is an I-81 crusher !!! Harrisburg and Carlisle up through Northeast PA is buried this run!

The 18z EPS looks good for all of CTP.

Just to see the beauty of it again... here are the 18z Euro snow maps.
