hckyplayer8 Posted May 27, 2012 Share Posted May 27, 2012 are you talking about the cell over pine grove? looks like that one had some weak rotation a little while ago Yeah. Dark as hell over Blue Mountain. Poured here for 60 secs and now nothing. Link to comment Share on other sites More sharing options...
NeffsvilleWx Posted May 27, 2012 Share Posted May 27, 2012 Yeah. Dark as hell over Blue Mountain. Poured here for 60 secs and now nothing. nice looking cell with a decent hail threat. I'm hoping the MCS in western PA makes it over the appalachians, but I know it's probably not going to. 1" hail reported in butler, and numerous reports of fallen trees from that system.

Well it arrived and is pouring out there now but no severe wind gusts, nor hail, nor virtually any lightning! Looks like good 'ol Blue Mountain is devouring the ferocity of the storms right by me.

MAG5035 Posted May 28, 2012 Author Share Posted May 28, 2012 We were hit hard by this line, power and Internet out. Lots of trees and power line issues. Had M67 mph gust where I was at. More details and pics eventually. Link to comment Share on other sites More sharing options...
Blizzard92 Posted May 28, 2012 Share Posted May 28, 2012 Storm pretty anti-climatic here just northeast of Harrisburg, but now getting a nice soaking rain. This will definitely be good for the gardens. Link to comment Share on other sites More sharing options...
PennMan Posted May 28, 2012 Share Posted May 28, 2012 Last night's storm was relatively unimpressive here in Bellefonte. A few decent gusts and brief heavy rain followed by an hour or more of light to moderate stratiform rain with occasional thunder. I was out of town for a family GTG Saturday, but it looks like we got hit pretty hard here in the afternoon. Lots of leaf litter and small branches scattered around, along with few larger limbs. Mud and gravel all over the place from the torrential rains. At our cabin in Snyder County we must have had at least 2" of rain Saturday afternoon in just over an hour, washed down the dirt road pretty badly. I'm looking forward to another hot and humid day today, hoping for another storm this afternoon. Link to comment Share on other sites More sharing options...
MAG5035 Posted May 28, 2012 Author Share Posted May 28, 2012 Still on generator power here this afternoon. And I think rumor has it our road isn't going to get fixed until tomorrow. At least the cable/phone has been restored, so i can use my internet. What a storm yesterday, I was not in Bellwood when it happened as me and my cousin went down to a friends farm to do some shooting. If you use Wunderground at all it is actually this station. The guys weather station (Davis Vue) measured a 67mph wind gust as the storm went through and it was one of the better storms i've ever seen around here. I was caught flat footed by not taking my laptop or anything to take a video. Then I came back into Bellwood and it was really a mess with multiple trees and power lines down.

MAG5035 Posted May 28, 2012 Author Share Posted May 28, 2012 Power has been restored. Took a walk in the woods behind our house and found a couple trees that got sheared in half. Now to attempt to dig up some radar data of what the hell went through here yesterday. I'm really mad I didn't have a device that could take video with me yesterday, cuz I would've had some epic footage of this line roaring through. Some pics: This first one was where I was at when the storms hit, which is near the Blair/Huntingdon line on Route 22. Had to clear a tree to get out. Next two are in and around Bellwood, first pic is one of the culprits for our 24 hour power outage (other end of our road had lines down as well. Second one was one I found shared on my Facebook from around the school. This type of tree damage was pretty widespread around town. (No the cows not real and the storm didn't put it there..haha.) This last one I just discovered on my F-book (another shared image). Nice debatable picture, poster said this was on the Saxton, PA side of Henrietta Mountain...so in other words this is far southeastern Blair county looking east over the ridge to the far NW portion of Bedford and/or far SW Huntingdon county. I would say yes this was probably a quick spinup along the edge of the line. Would really like to see some velocity data for that area and the Bellwood area as well as the edge of the line was pressing in. Link to comment Share on other sites More sharing options...

PottercountyWXobserver Posted May 29, 2012 Share Posted May 29, 2012 Great pics MAG! lol that complex of storms comletely missed me, so I wasn't able to witness the fury. I have only gotten .18" in the last 17 days, I'm really hoping we can get some rain with this next batch tomorrow, and if not, we might be in trouble for a little while. My grandparents spring well water is running low, very noticible drop in water pressure. Link to comment Share on other sites More sharing options...

My grandparents spring well water is running low, very noticible drop in water pressure. Hopefully we can get something for ya tomorrow. Looks like a pretty good chance you should be able to get some kind of half decent rainfall. Tuesday was also technically the day that had been looked at more for any potential severe as SPC has had us in a slight risk, and probably will continue to do so when they update soon. Looks like a more typical type threat for C-PA, with probably some decent cells firing ahead of a main line associated with the front. Could be a chance for some rainfall at the end of the week as well. About the Sunday event, I downloaded the radar data off of the ncdc website and was able to successfully load it into GR2Analyst. Heavily scrutinized the area that possible tornado pic had come from..but couldn't come up with any definitive support from velocity products. Here is the storm relative velocity image as Bellwood was getting victimized. Was hard to set a storm motion since the line was expanding outwards. For instance up towards State College a slower and more easterly trajectory was needed. I set the storm motion for this segment of the squall line for 160 (SE)@45knots for this portion of the squall line. This frame and the next frame had a pretty consistent 45-55knots associated with the gust front. After looking at all the stuff I missed while I had been away from the computer when the line blew up and of course when I lost power for 24 hours I must say that this is one of the best examples of a full strength MCS i've seen anytime recently for the middle of the state. Typically of course, we watch these lines get to about Pittsburgh or so and lose alot of punch once it gets off the Laurels. In this case, the MCS blew up in west central PA and made its full stride southeast. I really hadn't anticipated much of a threat beyond heavy rain and perhaps a couple instances of wind and hail with some pop up storms, and neither did CTP or SPC, who only had us in a general thunderstorm risk area. On the SPC mesoanalysis the MCS maintenance and derecho composite parameters weren't high at all, lending to a lack of bulk/0-6km shear and downdraft CAPE's that weren't too terribly high. What we did have were high MUCAPE and low level lapses.. which helped translate the very high winds to the surface. There was plenty of moisture (high PWATs) and heat to work with, and the atmosphere managed to make do and produce a very rapid and hard hitting line of storms.

Jmister Posted May 29, 2012 Share Posted May 29, 2012 Pretty strong wording from the SPC who raised hail and wind probabilities to 30% for much of the area in the mountains and east. 1300 outlook snippet: AN EXPANSIVE PRE-FRONTAL BAND OF TSTMS IS ONGOING AS OF 12Z FROM SWRN ONTARIO/LAKE ERIE SWWD INTO NRN KY...LIKELY FORCED BY THE LEADING EDGE OF STRONGER HEIGHT FALLS ASSOCIATED WITH UPPER SYSTEM MOVING THROUGH THE GREAT LAKES.

THIS DESTABILIZATION ALONG WITH THE EWD PROGRESSION OF UPPER TROUGH WILL SUPPORT A MARKED INCREASE IN STORM VIGOR AND COVERAGE BY EARLY AFTERNOON ALONG COLD FRONT AND/OR LEADING EDGE OF COLD POOL ASSOCIATED WITH THE ONGOING STORMS. THE STRONGEST MID- AND HIGH-LEVEL WIND FIELD ASSOCIATED WITH THE TROUGH IS FORECAST TO LAG THE WARM SECTOR TO THE W...LIMITING DEEP-LAYER SHEAR MAGNITUDES TO GENERALLY 30-40 KT.

THE GREATEST RISK FOR A TORNADO OR TWO WILL EXIST ALONG WARM FRONT OVER NEW ENGLAND WHERE LOW-LEVEL SHEAR WILL BE ENHANCED.

JamieOber Posted May 29, 2012 Share Posted May 29, 2012 MAG - Saturday/Sunday surprised the hell out of me. I wasn't expecting anything like that. Been keeping track of rain fall and IMBY, we are at 6.24 for the month. Might be able to swing 7"...this is reminds me of last year. What do you think about today's severe chances?

canderson Posted May 29, 2012 Share Posted May 29, 2012 It was hot as balls last weekend in Columbus. Holy crap it sucked. Looks like Harrisburg got some rain when I was away, good for the plants and flowers. Link to comment Share on other sites More sharing options...
Billabong Posted May 29, 2012 Share Posted May 29, 2012 Svr Watch up for the western half of PA. No doubt expect a new watch issued later for the other half... best threat so far this season. Although shear is not overly impressive, 0-6km shear around 30 knots is enough with plenty of instability to compensate. The storms already firing (with warnings already by 10:30am) to the west will probably develop into a southwest to northeast oriented line and propagate east through the state.... bowing out in places. Wet bulb zero level around 10k ft will likely aid in a decent hail threat as well. Link to comment Share on other sites More sharing options...

She's from Boston area, and never heard it. She loves it, actually. I think it's a total central PA thing but could be wrong. Svr Watch up for the western half of PA.
