OHSnow Posted May 24, 2011 Share Posted May 24, 2011 Tornado warning for Trumbull County, Ohio. Doppler radar shows a supercellular thunderstorm with some rotation north of Newton Falls or near Warren tracking to the east-southeast, very near to the track of the May 31, 1985 F5 tornado. If it holds together Mercer or Lawrence Counties may need severe thunderstorm or tornado warnings. Link to comment Share on other sites More sharing options...

OHSnow Posted May 24, 2011 Share Posted May 24, 2011 Not good. This looks like a tornado to me. Link to comment Share on other sites More sharing options...
OHSnow Posted May 24, 2011 Share Posted May 24, 2011 Fortunately, the storm has weakened a bit and there is not as much rotation... so the warning has been allowed to expire and replaced with a severe thunderstorm warning. Still capable of producing golf-ball size hail per the warning however. Link to comment Share on other sites More sharing options...

blackngoldrules Posted May 24, 2011 Share Posted May 24, 2011 Seems like that line of storms that were charging through Ohio earlier did the splits when it reached our area.

OHSnow Posted May 25, 2011 Share Posted May 25, 2011 I'm detecting a little rotation with the line of storms passing through northern Ohio... nothing major, but I wouldn't be entirely shocked if a brief, rainwrapped F0 or F1-type tornado occurred somewhere along that line as it moves eastward. Also potential for golfball (or larger) hail... VILs are practically off the chart. Link to comment Share on other sites More sharing options...

OHSnow Posted May 25, 2011 Share Posted May 25, 2011 No sooner do I note the rotation and a tornado warning is now in effect for the Akron area. Trained weather spotters reported a funnel with that at 7:38 PM near Cuyahoga Falls. That corresponds right to where I was detecting the weak rotation... that area of rotation is moving into northern Portage County. There's another area of weak rotation just north of Akron, which may follow the path of that rotation. It's also capable of producing funnel clouds or a weak tornado.

blackngoldrules Posted May 26, 2011 Share Posted May 26, 2011 The storms that are in northern Ohio right now may effect northwestern PA later, if they hold together by then. May just be a little too far north, and moving in too much of a northeasterly direction, to affect our area at all. Unless something develops on the southern end, then we may have a shot at something. Something to keep an eye on anyway. Looking ahead a bit, it looks like the unofficial start of summer is going to feel very much like summer. Temps may get up near 90 around Memorial Day. Very warm weekend coming up it looks like too.

OHSnow Posted May 26, 2011 Share Posted May 26, 2011 Hmm... looking at the data back home at Youngstown, today was the 8th straight warmer than normal day. Looking at the forecasts for the next week, as well as long-range models, that streak could really begin to add up. I'm thinking this summer could be similar to last with sustained warmth and humidity, but no really extreme heat (due at least partially to the very wet ground).

north pgh Posted May 26, 2011 Share Posted May 26, 2011 It looks like the line is weakening. This is reminding me of several years back where almost every mcs that came from the northwest falls apart as soon as it hits Allegheny County. Link to comment Share on other sites More sharing options...
