Pittsburgh/Western PA Winter 2024-2025 Thread

[Ahoff]

Had a nice blast in the south hills.

[blackngoldrules]

I'm on the back edge of it in the South Hills now but it looks like there's some backfilling so maybe we'll get a little more?

Nice burst again.  Too bad KPIT isn't getting this, so totals will officially be pretty low.

 

[Rd9108]

Idc if this next wave is south. I'm rooting for this. This is crazy.

 

[Ahoff]

But honestly, we go from winters where we're too far south for the good to too far north.  We need a good old middle ground winter.  Maybe soon.  Not that this one's been bad, just funny every major storm has missed south this year, after years of waiting for more southern solutions.

Looks like more light snow should develop as the afternoon progresses. Somewhere between a quarter to half an inch so far.

[Mailman]

Try to cheer you folks up...

 

[TheClimateChanger]

Not much of anything here. Minor coating earlier, snowing lightly again now with a new light coating.

[Rd9108]

NAM 3k is showing two solid squall lines on Tuesday so maybe something to watch for.

[SteelCity87]

That line has been hammering far west AGC for over an hour now. Curious what they've picked up since.

Looks like a little Squallish weather to move in.

Yeah HRRR shows a squall through the center of the county. See what happens. 

That snow game was fun to watch.

Hope that band holds together and moves east spending some time over my yard. Looks like it originated off Huron, but may be losing its link as the winds shift. Not super confident it makes it here.

[TheClimateChanger]

Snowing quite heavily here. Looks to be about an inch or so of new accumulation. Wasn’t expecting much this far northwest.

[TheClimateChanger]

Very impressive snowfall rates, with rapid accumulation. Watch out for that coating.

 

[blackngoldrules]

Snowing very hard in Bethel right now. I'll enjoy this for another 10 minutes! Lol

Snowing hard here. Not really a squall. Not much wind but big fluffy flakes. 1/2 mile visibility and accumulating.

[Burghblizz]

POUNDING here. 2” last hour 

[meatwad]

Coming down heavy here in Monroeville.

[RitualOfTheTrout]

Ugh.. as expected completely fizzled before making it to westmoreland. 

[RitualOfTheTrout]

Getting some intermittent light to occasionally moderate bursts as what's left of that band finally made it. Much higher ratio / better flake structure than any point today. Should add another half inch or so.

Too bad the arctic front is coming through at 3am, could be fun, although Ill be up for work at 430, roads will probably be dicey.

The current 00Z sounding alludes the the heavily anticipated
arctic frontal passing overnight tonight, with a tropopause of
500mb with dry stratospheric air above that. An adiabatic,
nearly saturated layer is observed from the surface to roughly
800mb, which has been responsible for the convective snow during
the early overnight hours tonight. The forcing for snow has
mostly been the stark surface convergence as the cold air
bullies is way in along the front. The frontal passage will
cross tonight, leading to dramatic drops in temperatures. The
most likely passage time will be roughly 9pm for Zanesville, 1am
for Wheeling, 3am for Pittsburgh and Morgantown, 5am for
Latrobe, and 7am for DuBois.

Flow is expected to be progressive enough to result in minimal
totals. Less than 1" of additional snow may be possible along
the front on in dry, fluffy, high- ratio convective snow.
Visibility may drop as low as 1/2 mi, but even lower
visibilities are possible in blowing snow. Observations in Ohio
indicate winds gusting as high as 20mph to 30mph along and
behind the frontal passage. Webcams show snow-covered roads.

[Burghblizz]

Another nice band dropping into SW Butler county and entering northern AGC.

i got a coating of pixie dust off the initial system, but probably will be close to 3” total off these LES bands.

Well this didn't age well, may have missed that specific band, but made up for it between 11pm last night and now. When I left the house at 4:45 I had 2 fresh inches since 11pm and that heavier band was about to pivot through which I ended up driving through, heavy snow and 12 degrees, cars sliding all over on 28 pretty crazy, then when I got to the city clear as a bell until I hit another band. 

Late save by the lakes on this one. Looks like flow is rapidly shifting westerly so the fetches will get cutoff shortly but the arctic air will be spilling in. Wondering if this may be our last bout of LES assist as this incoming airmass should finish icing Erie over and start building up quickly on the others.

Yes I shoveled and salted my driveway last night so I could get up the hill this morning. I woke up to it snow covered and had to shovel again All in all I picked up 1/2 inch of snow during the day from the first batch, 1 inch last night and another 1 inch overnight. Currently 9 and bitter with the biting wind. 

[Burghblizz]

Got 3.5” total last night. Didn’t happen exactly the way I thought, but definitely did the job of freshening up the snowpack.

[Gordo74]

We got around 1” yesterday but picked up an additional 3-4” overnight. The latter seemed to catch everyone off guard - some streets are not touched from the overnight snow near me.

Pretty great event all in all. Now for the frigid cold. Hopefully the pipes are up for it!

[Rd9108]

Idk what we got just north of the city probaly 2 or 3 from the whole event. Nothing crazy but helps with the snowpack and let's see how low the temps go. Will we finally break -10. Gonna be tough.

Still looking like some possible impacts tomorrow. NWS thinking less than an inch, but with temperatures this cold a brief burst of heavy snow will deteriorate roads pretty quickly especially later afternoon / early evening.

Along with cold weather, a potential shortwave is expected to
cross the region Tuesday afternoon and increase the threat of
hazardous travel due to snow. Snowfall amounts are expected to
stay below Advisory criteria (likely 0.5 to 1.0 inches in
isolated areas; a trace to 0.5 elsewhere). However, brief
periods of low visibility from heavy snow can`t be ruled out.
The 0-3km CAPE values range from 25J/kg to 50J/kg along the
trough axis. Hi-Res guidance also has some noted potential
stronger bands (reflectivity on the radar could measure 20DBZ to
30DBZ at times) between 3pm to 6pm (including Pittsburgh). If
models remain consistent with this potential outcome, short-
fused special weather statements and/or snow squall warnings may
be needed to highlight the threat.

Nam 3k kept showing those squalls so I'm assuming they will materialize.

Btw this is a crazy map
