Central PA Spring 2025

[MAG5035]

Looking at mesoanalysis, dynamics are definitely the big factor in the severe threat from this line. Effective helicity is pretty notable in a narrow corridor of west central PA just ahead of the line. 

Same goes for effective bulk shear as well. Limiting factor is CAPE, which is only of the few hundred J/kg variety in western PA. Thus, QLCS spinups are quite possible directly associated with the line given significant helicity/shear. Eastern PA still pretty stable, so we shall see how the atmosphere evolves as the line traverses PA.

We’re def in the warm sector here. Quite warm/humid considering the date (66/58ºF on the station here). Winds are really ripping. KAOO wind is SSE 33mph gust to 45 with a high gust of 55mph.

@WmsptWx is right in the tornado warning or just outside it.

64/60 here, so just one off on each. It feels sticky and summerish, even with the wind. I just wonder how far east the really severe weather can get.

Hopefully some one with expertise chimes in, but I did stay in a Holiday Inn express last night.

It might depend on if any sun can raise cape some ahead of line

Looks like nasty stuff going to stay North of me here in Bedford Co.

[MAG5035]

The wind part was quick but it was legit. Power flashed off at the height of the winds so unsure of the gusts, but definitely was easily of the severe variety. Had some pea sized hail as well.

Sun is peaking through

Sky is brightening in Marysville as well.

Power has now gone out after the fact. 

At least a couple trees came down in the woods around my parents house up the road in Bellwood.

3 diff tornado warnings now in N Central PA

Meanwhile here it is gusting to 46 mph from the SE, rare stuff. 

[str8liner]

A couple claps of thunder, wind and some heavy rain here.....See, even the severe spring events are meh for me.

I have always said if you like boring weather, Bedford Co. is the place to be. 

[canderson]

You can see storms firing on the dry line around Williamsport. 

The sun just came out for the first time in Harrisburg.

The issue I see is the total lack of lightning south of state college currently. This may just be some windy rain

Wind has knocked out power in the city. It’s blowing 50 now.

Less than that in Three Springs. 

 

Ridge and Valley from Bedford through maybe Sunbury is probably the most boring weather region in this state.

It’s 72 but the humidity is down to 57.  It was 67 about an hour ago. 
 

Big, big winds in what seems like a gravity wave here.

Like entering W Cumberland was just warned for severe.

I think I had a gust about 30 minutes ago that was stronger than anything since Isabel here. My trashcan is gone. Don't want to exaggerate but it had to be 60+.

You had some sun before us and that can upset stable stuff and the 70-80kn winds are at 2-3k so doesn’t take much to mix them down. I don’t doubt that guesstimate at all.
