Blizzard of 93

Hopefully we are measuring snow & sleet and not ice accumulation!

I riding the Euro train that I posted above...not the Chattanooga one!

Hopefully things trend towards more snow or even sleet...anything but ice! @MAG5035 yesterday thought we had a chance to get more sleet & snow vs. freezing rain except for the southern tier. We still have 2 days to go before we see where the lines set up.

The 0z Euro still provides a moderate snowstorm for CTP & northern MD for Thursday with a storm that tracks to our south. This snow map is just for the Thursday period.

Here are the 6z Euro snow & ice map for Tuesday, It will not take much to move the ice or snow line in either direction with 2 days to go.

The 6z Euro said the northwest half of PA will be shoveling on Tuesday while the southeast half will be ice skating.

This could be a memorable week of Winter. Monday/Tuesday front end snow to major ice followed by a potential significant snowstorm on Thursday.... Sign me up!

The 18z Euro for tomorrow came in with a slightly more snowy look for the PA turnpike area on north. Now there is the chance of a solid coating of snow according to this run.

Here is the snow, sleet & freezing rain from the 18z GFS.

The 18z GFS agreed with your preference for a colder solution. It keeps the low below us and tracks it towards the DelMarVa and then off of the coast. There is High pressure to our north and Arctic air waiting to press in from the west. If the low takes this track, and the cold air presses even slightly further south, all of CTP could be looking good for more snow. As it stands now verbatim on this run, the 6 inch snow line gets down to Altoona & Selinsgrove. The 3 inch line gets down to Harrisburg this run. A lot of sleet shows up in the I -81 to I-78 corridor, while the bulk of the freezing rain hits the southern tier. Still a few days to go, but Plenty of time for this to trend for the better or worse, but I like where things are heading at this time.

Tomorrow night into Sunday am has always been a light event, but we might get a light dusting of snow or sleet or a minor glaze of ice, which could still cause trouble on the untreated roads.

The 18z Euro Op came in colder for the Saturday night event and looks similar to the runs a couple of days ago that brought 1 to 3 inches of snow to a good chunk of CTP, with mixing confined to the southern tier.

Here is Tuesday 7am on the 18z GFS.

Yes, very nice snow thump on the 18z GFS! A good portion of CTP stays mostly snow, except for the southern tier, but by that point, a lot of snow is on the ground according to this run. Here is the snow map for the Tuesday storm,

Here is the 12z EPS snow map for the Tuesday storm window. I think we should get at least a decent front end thump of snow. The question will then be if we mix, & if so, for how much of the event.

12z EPS was indeed east of the Op for the Tuesday event & the Thursday possibility. For the Tuesday event, Here are the low track clusters showing the transfer to the coast by a large group of ensemble members. This could put CTP in a great spot for more snow than mix if the coastal takes over at the right location.

Tuesday could be the main event, but Saturday afternoon into early Sunday could bring a couple of inches of snow followed by mixed precip.

For Tuesday, The 0z EPS is starting to come around to the idea of the initial low giving way to a developing coastal storm that tracks off of the DelMarVa. Here are the low clusters and the snow map just for the Tuesday storm on the 0z EPS. Still work to do on the EPS to get to a GFS like solution, but the trend is good for now.

The 6z GFS took just about an ideal track for the Tuesday event. It keeps the low under us and was mainly a snow event for CTP. The snow map is just for the Tuesday storm.

The GFS on Tuesday takes the low from North Carolina to off of the coast of the DelMarVa. With all of the High pressure to the north & west that is supplying Arctic air, this should trend to a colder look with at least a very solid front end thump of snow & then mixing for some areas depending on the final track.

My bar for this event for MDT is 3.5 inches to get the seasonal total to 30 inches. This would get them to be within 2 inches of exceeding the climo seasonal average. Everything after this weekend through March would just be stats padding to see how much we can pile on!

The 0z GFS is not backing down for tonight’s event! Here are the 10-1 & Kuchera maps.

Harrisburg MDT measured 2 inches last Sunday.

For Saturday, The 18z Euro & GFS both had 1 to 3 inches of snow. The models have been trending to a more snowy look for Saturday pm in especially from near I-81 on west. These maps are just for the Saturday event.

Flake size already picking up. Car tops are covered.
