I've only seen it in person 3 times in my entire life. Yeah cause to me a severe thunderstorm will contain the following: Winds of at least 60 MPH but for a good one at 70 MPH Cloud to ground lightning And lots of thunder ... Along with hail...preferably at least a quarter size cause we have had nickle, dime, and pea size plenty of times in the past .. This contained 2 minutes of nickle size hail.... When you been thru the likes of a hurricane..2 minutes of hail (if that) equates to nothing... No funnel cloud in my vicinity... Link to comment Share on other sites More sharing options...

FYI dude, the definition of a severe storm is disjunctive, not conjunctive. So if you see any of the "severe" events, that's a severe storm. It's not necessary to see all of them (and seeing all of them in a single storm is quite rare). Link to comment Share on other sites More sharing options...

IsentropicLift Posted June 30, 2015 Share Posted June 30, 2015 Mesoscale Discussion 1247 < Previous MD MESOSCALE DISCUSSION 1247 NWS STORM PREDICTION CENTER NORMAN OK 0157 PM CDT TUE JUN 30 2015 AREAS AFFECTED...PORTIONS OF FAR ERN PA...FAR WRN NJ CONCERNING...SEVERE THUNDERSTORM WATCH 372... VALID 301857Z - 302000Z THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 372 CONTINUES. SUMMARY...THE RISK FOR A COUPLE OF TORNADOES WILL EXIST ACROSS A SMALL CORRIDOR OF SEVERE THUNDERSTORM WATCH 372 -- ACROSS PORTIONS OF FAR ERN PA AND FAR WRN NJ. DISCUSSION...SFC OBSERVATIONS INDICATE PRESSURE FALLS AROUND 1.5 MB PER 2 HOURS NEAR AND E OF AN AXIS OF DISCRETE CELLS EXTENDING FROM NEAR ALLENTOWN TO W OF WILMINGTON DE WHERE DESTABILIZATION CONTINUES. OCCASIONAL MESOCYCLONES HAVE BEEN EVIDENT BASED ON SINGLE-SITE RADAR DATA. CONTINUED DIURNAL HEATING AMIDST MIDDLE-60S SFC DEWPOINTS WILL MAINTAIN PERSISTENCE OF THIS ACTIVITY. DYNAMIC PERTURBATION PRESSURES AT THE STORM-SCALE MAY ALLOW EWD PROPAGATION OF THIS ACTIVITY IN AN OTHERWISE SWLY-FLOW-ALOFT REGIME...PERHAPS TAKING IT TOWARD FAR WRN NJ AS WELL AS PARTS OF THE PHILADELPHIA AREA IN THE SHORT-TERM. DOX/DIX VWPS SAMPLE A VERTICALLY VEERING WIND PROFILE IN THE LOWEST COUPLE OF KM AGL THAT MAY CONTINUE TO ENHANCE LOW-LEVEL SRH SUFFICIENTLY FOR THE RISK OF ONE OR TWO TORNADOES. POOR MID-LEVEL LAPSE RATES AND ONLY MODEST LOW-LEVEL FLOW STRENGTH MAY MITIGATE A MORE SUBSTANTIAL TORNADO RISK OVERALL. ..COHEN.. 06/30/2015 Link to comment Share on other sites More sharing options...

Drz1111 Posted June 30, 2015 Share Posted June 30, 2015 It's amazing how we didn't even see this coming. Surprise severe days are the best severe days around here. TBF, the area where these couplets are forming was on the edge of the slight risk, and SPC highlighted the area near the boundary for better low level shear and a higher tor risk in their morning discussion. But generally agreed, this is a very tasty radar for severe in this neck of the woods. Link to comment Share on other sites More sharing options...

I know what the definition is lol I been following the weather for 40 years... this would not have even classified as an event of writing home about. And yes PRIOR to Sandy this area had seen PLENTY of severe storms with winds over 60 MPH.. quarter size hail (more rare i think once) but plenty of pea and nickel size hail.. with cloud to ground lightning and thunder that would shake the house.. to each his own what he expects out of a severe thunderstorm but this was a dissapointment.. how can you classify something without thunder and lightning as a severe storm yet alone even a thunderstorm? It was literally 2 minutes less of hail and 5 minutes of heavy rain-thats it.. Link to comment Share on other sites More sharing options...

Well, if your view is that a severe thunderstorm means what you want it to mean, and you mean it to mean something other than what the rest of the country defines a severe thunderstorm to be, then your logic is impregnable. For the record, when the rest of us say severe, we're using the NWS definition that the other 320 million people in this country use, and not the definition used by the dude posting under the nom de plume "atownwxwatcher".

Tatamy Posted June 30, 2015 Share Posted June 30, 2015 I'm in Bethlehem Township, PA and that feature just passed right over me 10 minutes ago. It was a sight to see. No tornado - just a rapidly rotating wall cloud. It's moved on into Warren County, NJ. In 40+ plus years of weather watching I have never seen anything like it. There was no wind to speak of at the surface. No thunder either. It just got deathly quite and still. But that was the extent of it. Link to comment Share on other sites More sharing options...
