Blizzard of 93

Great 18z Euro run. This is turning into another long duration event if it goes down like this! Snow from early Thursday morning that continues at least lightly until Friday afternoon.

Lol... don’t I wish...busy with work !

Absolutely great 18z GFS run... let’s lock this in!

Those afternoon gusts were brutal... @canderson was right!

The 18z GFS has a 18 to 24 hour event from Thursday morning to overnight into early Friday with light snow still ongoing.

We still need to get the snow on the ground... We all win if we get a Warning level snow!

For next Monday, The 12z Euro has a nice Advisory level event for us. The tracking train keeps rolling along this year!

I like your thinking!

Here is the latest Discussion & the Event snow maps from CTP as of this morning for the Thursday into Friday snow chance. ”The 1035 mb high pressure system responsible for fair weather on Wed will move northeastward into New England by Wed night, setting the stage for good cold air damming ahead of the next storm system. A shortwave trough originating in the southwestern US will round the base of a deep, longwave trough and provide broad vertical ascent to develop an East Coast cyclone Thu into early Fri. Models still differ on how the storm will impact central PA, particularly on how far north and west heavy precip will get. A blend of the guidance shows QPF ranging from 0.5 in the northwest to 0.75-1.00 in the southeast. Much of this looks to fall in the form of snow, given the aforementioned cold air damming. A west-east oriented band of fgen forcing showing up in some of the guidance suggests a northward propagating band of moderate to heavy snow is possible shortly after the onset of precip during the day Thu, but it is too early to say with confidence if this will happen. For now, went with a general 10:1 ratio of snow to QPF for most of the area, and a bit lower in the SE where the column is warmer and there is more potential for mixing. This translates to a general 5 to 8 inches inches of snow for a large swath of central PA, 3 to 6 inches in the NW where QPF is limited, and 3 to 6 inches in the SE where temps will be warmer. Most of the snow will fall between late Wed night and late Thu night.”

The 6z GFS & GFS Para continued to look great for the Thursday into Friday storm. The old GFS is mostly snow, except some mixing towards the end of the storm after a very good snow thump. The Para kept just above everyone snow for the duration of the storm. These are 10-1 maps.

The precious, somehow beloved by many, NAMs are coming onboard at 6z. This was a NAMing indeed! Here are the 12k & 3K (run ends at 60 hours) at 6z

Here are the 0z Euro 10-1 & Kuchera snow zoomed in maps for CTP.

The 0z Euro Op run was very nice with mostly snow for just about everyone, even at the height of the storm.

The 0z GFS, Para & GEFS continued to escalate the Thursday into Friday for many of us!

The 0z ICON has the snow thump for most of the LSV!

Yes, the 0z NAM took a big step towards every other available model for Thursday. Very nice front end thump despite only taking a step at this time. I’m looking forward to the rest of the 0z runs.

The 18z EPS remained steady for our Thursday into Friday snow chance. The 18z Euro Control looks very nice as well!

The 18z Euro still looks very good leading in to the storm with a well placed High pressure over Quebec as the steady snow gets underway in CTP. By Thursday evening the High is still in a great spot as the heavy snow still is unloading on all of us from the MD line on north. I like seeing the snow max zone at this range to our south... plenty of time to get this into the LSV!

@MAG5035 We were on the same page with our CTP zone posts within a minute of each other!

CTP is ramping up the zone forecasts for Wednesday night into Friday morning. Here is the current forecast for Harrisburg. Wednesday Night A chance of snow after 2am. Mostly cloudy, with a low around 23. Light and variable wind. Chance of precipitation is 50%. New snow accumulation of 1 to 2 inches possible. Thursday Snow before 2pm, then snow and sleet.

Lol...send the train North about 100 miles & then we will be Back in the jackpot that is South of DC !

The 18z Para GFS is on board the snow train as well ... Choo .... Choo!!!

I didn’t see the 12z Euro & 12z EPS posted from earlier... so here they are...

Here is the 18z GFS 10-1 ratio map just for this storm on Thursday into Friday.

Yes! Let’s go Euro in an hour!
