Blizzard of 93

Exactly! I think the Tuesday/Wednesday wave is coming into better focus. I like the Warning level snow potential for much of CTP. Beyond that, stay tuned. 50 to 100 miles will make a difference on where the boundary sets up.

But we should throw out Weatherbell maps because they are not the precious Pivotal maps… Lol!

Also with the low dew points, temps will fall when steady precipitation begins.

There will be tons of issues tomorrow. This should not be downplayed.

29/17 in Marysville & cloudy

6z GFS brings out the system next week in a couple of waves, but delivers the goods this run.

0z Euro was a PA crusher for next week’s snow chance.

0z ICON is a hit for next week.

I’m trying to rest up a bit…it’s going to be a long week or so with 3 events. Fun times not far away on here.

To clarify, we have seen this amount on an ensemble run a couple of days before a major storm, like in 2010 or 2016. But I have not seen this amount over a 16 day ensemble run period, especially with the first major snowstorm chance being 7 days away. MU is right… Buckle Up!

This is something that I have never ever seen in my over 20 years of following weather models closely… The 18z GEFS snow map showing over 14 inches of snow.

LSV is in the jackpot for next week.

The overnight ensembles are still looking very encouraging for the next 2 weeks.

More from CTP for this first event. By Wednesday evening, broad southeast flow in the wake of retreating high pressure will keep cold air locked in east of the mountains as a warm nose of overrunning precipitation overspreads the region. The aforementioned band of snow will gradually lift northeast ahead of a broad area of low pressure moving in from the Ohio Valley with a transition to sleet and eventually freezing rain during the overnight hours. Model soundings have indicated that the layer of cold air at the surface could be a little bit deeper than previous runs, indicating potential for a longer period of sleet overnight before an inevitable transition to freezing rain. QPF amounts are generally 0.25-0.5" along and north of I-80, >0.75" in the Laurels, and 0.5-0.75" east of I-99 and south of I-80. Accounting for the expected precipitation type transitions and timing, the current forecast paints snow/sleet accumulations of up to an inch for much of central and northeast PA (higher amounts under the aforementioned Wednesday snow band), and widespread 0.10"+ ice accretion with amounts >0.25" favored in the Laurel Highlands through midday Thursday.

From CTP forecast discussion… Temperatures are progged to rebound considerably Thursday afternoon, though temperatures soaring into the 50s appears less and less likely as the event draws closer. It is difficult to scour out the cold air after these events, so trending below guidance seems prudent

The LSV holds the cold & it is tough to scour out in these icing situations.

RGEM freezing rain

RGEM sleet

Sign me up for either NAM for this first event. I don’t mind ice storms as much if there is an inch or 2 of snow at the onset. It just makes the ice look more Wintry to me & it gives a little traction on the roads.

“Ice showers”, Lol!

I’ve seen both NAMs disagree with each other 6 hours before game time.

For the Saturday event, the 18z Euro has a couple of inches of snow before the ice takes over.

12z GEPS & 12z EPS are also quite remarkable. The signal has been showing on the ensembles & Ops for several days now, across all major guidance.

18z GEFS with yet another impressive run for the 16 day period.
