Blizzard of 93

Happy hour GFS looks good for both events. Here is tomorrow into Monday

Great point about the Canadian High. Hopefully it keeps trending better.

I like tracking multiple events in the short to medium range… let’s go!

Yes, hopefully we get a decent little event tomorrow pm while tracking the Wednesday front ender!

The 18z NAMs both are bringing 1-2 inches back to the LSV. Maybe the start of the trend back to a respectable Advisory event for parts of the LSV?

I’d sign up for the this Ukie for Wednesday! Most models for tomorrow as of a couple of days ago had Advisory level 1-3 or 2-4 inch amounts, especially from Harrisburg north & west. The exceptions were that 1 epic Euro run & that Ukie run that you re-posted this morning. I still think there is time for the Tomorrow event to trend back to a 1-3 inch snow for the LSV like the HRRR just showed at 18z.

Here is the 18z HRRR snow map

The 18z HRRR looks interesting for the Tomorrow pm into Monday am event. It has the initial period of snow to mix & then it shows a secondary low development that brings a decent period of snow on the back end.

The 12z EPS & 12z Canadian ensembles still look good for the Wednesday snow thump.

ALEET…I mean… Advisory…for some southern PA counties as well…including mine! Winter Weather Advisory URGENT - WINTER WEATHER MESSAGE National Weather Service State College PA 213 PM EST Sat Jan 21 2023 PAZ024>028-033>035-056-221000- /O.NEW.KCTP.WW.Y.0003.230122T1900Z-230123T0400Z/ Cambria-Blair-Huntingdon-Mifflin-Juniata-Somerset-Bedford-Fulton- Perry- Including the cities of Johnstown, Altoona, Huntingdon, Mount Union, Lewistown, Mifflintown, Somerset, Bedford, McConnellsburg, and Newport 213 PM EST Sat Jan 21 2023 ...WINTER WEATHER ADVISORY IN EFFECT FROM 2 PM TO 11 PM EST SUNDAY... * WHAT...Wet snow then mixed precipitation expected. Total snow accumulations of up to one inch and ice accumulations of up to one tenth of an inch. * WHERE...Portions of central Pennsylvania. * WHEN...From 2 PM to 11 PM EST Sunday. * IMPACTS...Plan on slippery road conditions. * ADDITIONAL DETAILS...There`s a chance that the changeover to mixed precipitation or freezing rain could be delayed by up to a few hours late Sunday. This would add around another inch or so to the snowfall totals.

The 12z GFS has another Winter storm the last couple of days of January & looks juiced for early February with plenty of cold air around.

Widespread 3 to 5 inches of snow for all of CTP according to the 12z GFS.

The high in Quebec is in a good spot as the main slug of precip arrives.

The 12z GFS was Very good again for Wednesday for CTP…sorry I logged off for a bit… @Bubbler86 must be out to lunch today!

While we wait for the rest of 12z runs to roll in…. Let’s have a little fun in looking at the 6z GFS snow map for the full 16 day run! @paweather this is for you…. Maybe we finally cash in this week & next week?

The 12z ICON has the Wednesday front end thump for all of CTP. The snow thump then changes to a little rain & then the dry slot quickly ends the rain this run, so maybe all of our snow won’t be washed away.

The 6z EPS improved the snow a little for the Wednesday event. It now gets the blue through all of Lancaster county and well into MD.

Also, the chances continue after next Wednesday’s event. The 6z GFS has this for Ground Hog day.

Yes, but I’ll take what little bit of snow that I can get tomorrow while tracking the Wednesday event which is improving.

The 0z EPS & 6z GEFS ensembles improved again for the Wednesday potential. This is only the 24 hr. period for the Wednesday event.

Yes, there is nothing better to me in this hobby than watching it snow, while tracking another snow chance a few days later. This week, we have the chance of getting snow on snow.

High pressure in southern Canada seems to stick around longer this 6z GFS run, which helps to pull the snow line even further south into MD. The “blue” now gets into northern MD this run, which @Itstrainingtime likes to see, which gives us some cushion.

The 6z GFS still looks great for the Wednesday front end thump of snow for all of CTP.

Here is the 0z Euro Wednesday snow map for this storm 24 hr period.

For Wednesday, the 0z Euro has a good front end thump of snow for all of CTP, including the LSV.
