Blizzard of 93

CTP is going to make us wait for MDT’s official measurement today. The 5 pm climate summary just has “MM” now.

Moderate snow in Marysville continues with eyeballing over 1 inch covering all surfaces.

Snowing in Marysville with all surfaces lightly covered at 6 am.

School here is cancelled for Susquenita.

0z GFS holding strong for even the LSV

27 temp 20 dew point Bring it!

I really like seeing current temps region wide in the 20s with dew points in the upper teens at this hour.

Notable bump southeast on the 0z 3k NAM from its 18z run, which helps York & Lanco 0z top 18z bottom

18z EPS was also a step in the right direction, even for the York & northern Lanco crew.

The 18z Euro improved over 12z for Harrisburg & York.

CTP with a very detailed forecast here : SHORT TERM /3 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/... Quick moving storm to bring the first widespread plowable snowfall of the season to central PA early Tuesday. The snow accumulation will result in travel impacts and disruptions for the Tuesday morning commute to work and school. Key Takeaways/Messages: *Snow onset 3-6AM window from west to east (give or take 1hr) with temps cold enough to support accumulation and deteriorating road conditions *Heaviest snow 5-10AM west to 7AM-12PM east with rates generally <1 in/hr (0.50-0.75" range) *Snow end time 10AM-2PM west to east; snow showers or flurries linger through the evening downwind of Lake Erie over the western Alleghenies and Laurel Highlands *Total snowfall in the 2-4/3-5" range for most of the area; exceptions are the far southeast (lower amounts 0.5-2") due to rain/wintry mix and the Coal region into the Poconos (higher amounts 4-6") *Sullivan County has the highest probability (50-70%) of localized snowfall >6" *Snow character will initially be on the dry side with temps in the 20s but trend wetter/slushy as temps rise near/above freezing by the early afternoon *No significant wind impacts expected with this system; winds will increase early Tuesday night with gusts up to 20 mph We are most confident in a widespread moderate to high end winter wx advisory scenario given the fast moving nature of the system. We anticipate the highest snowfall totals over the northeast to east-central quadrant of the CWA or to the east of US-15 and north of I-81/I-78. Any melted snow or slush will refreeze Tuesday night with low temps in the lower 20s.

CTP : SYNOPSIS... * The first widespread plowable snowfall of the season will cause travel impacts and disruptions early Tuesday * Arctic cold front will deliver snow showers/squalls and bitter cold temperatures Thursday through Friday morning * Reinforcing cold blast will ensure the first part of December will be colder than the historical average with the potential for another storm system this weekend or early next week

The 18z GFS says hello!

I’ll be sleeping because it is not supposed to start until closer to 6 am, Lol!

I like this CTP call for most of the region, but I think a few lucky spots could get closer to 5 depending on where the heaviest bands set up.

NAMs finally at 6z jumped on board for most of us & the GFS held serve too.

0z GFS holds serve & delivers Warning snow to most of us again for Tuesday.

I’d sign for that to get on the official board for the season.

I also gassed up my snowblower and started it up. Ready for whatever this week brings!

@Itstrainingtime I did my snow mow today!

18z GFS still looking good for Tuesday for Warning snow potential for the vast majority of the Susquehanna Valley.

The Friday night into Saturday am potential event is still there on the 12z GFS & Canadian.

12z RGEM is looking good as well.
