Potential for a rather potent severe weather event

That's such a tough situation to wish for. That's like being asked if you would rather see Miley Cyrus or Taylor Swift naked

 

I have my vote, and it wasn't that hard.

 

Oh wait, about storms? I can be happy with a long-tracked significant severe supercell, but I think we're due for a good EF-2 in our CWA.

If we can get steep lapse rates and the instability advertised with 50+ knots of effective bulk shear I would really be shocked if we didn't see an EF-2 or higher somewhere tomorrow

I'd probably like to see winds stay backed longer to keep helicity high for EF3 stuff, but with so much shear in the lowest 1 km, an EF2 shouldn't be too hard to pull off even off the brief ones.

 

I'm looking for the first TDS on GYX. I want to see what it will look like in our area. Though it probably won't be much different than BOX's or ALY's from the last couple of years.

DAY 2 CONVECTIVE OUTLOOK  
NWS STORM PREDICTION CENTER NORMAN OK  
1230 PM CDT MON JUN 22 2015  
 
VALID 231200Z - 241200Z  

   
..THERE IS AN ENH RISK OF SVR TSTMS
 
 
...THERE IS A SLGT RISK OF SVR TSTMS FROM THE NERN U.S. THROUGH THE  
MID ATLANTIC AND SRN OH VALLEY...

..SUMMARY
 
 
SEVERE THUNDERSTORMS WITH LARGE HAIL AND DAMAGING WIND GUSTS ARE  
EXPECTED FROM PORTIONS OF NEW ENGLAND INTO THE CENTRAL APPALACHIANS  
AND OHIO VALLEY. FARTHER WEST...OTHER SEVERE STORMS WITH LARGE HAIL  
AND ISOLATED WIND DAMAGE WILL ALSO BE POSSIBLE IN THE CENTRAL AND  
NORTHERN HIGH PLAINS FROM LATE TUESDAY AFTERNOON THROUGH THE  
EVENING.  
   
..NORTHEAST STATES
 
 
MCS WILL BE ONGOING EARLY TUESDAY MOST LIKELY OVER PORTIONS OF NEW

TO EXTEND FROM SRN NH AND VT NWWD INTO SRN QUEBEC. THE ATMOSPHERE IS  
EXPECTED TO DESTABILIZE IN WAKE OF AND UPSTREAM OF THE MCS AS RICHER  
LOW-LEVEL MOISTURE IS ADVECTED NEWD THROUGH WARM SECTOR IN ADVANCE  
OF A SEWD ADVANCING COLD FRONT. SOME BREAKS IN RESIDUAL LOW CLOUDS

IMPRESSIVE DEEP LAYER WINDS ASSOCIATED WITH A PROGRESSIVE SHORTWAVE

NEW ENGLAND WHERE A THREAT FOR A FEW TORNADOES WILL BE CONDITIONAL

That's a pretty great discussion, matches my thoughts exactly. A little conditional, but yet significant severe possible. Just feels like an enhanced kind of day.

My true meaning being......it's about time. 

 

Obviously a cautious approach is warrented, but I just went from 5% to 30% lol.

 

Also as a side:  I love the different number of emojis that we have.  We have Microsoft Lync at work and the emojis are so disappointing.

 

Yeah I wasn't comfortable with the prior risk outlook, neither was BOX, so collaboration was great today. We all talked it out and agreed this was best.

 

Just feels like an enhanced kind of day, not a run of the mill slight.

I'm really really amped up for this . Could be a day that goes down in infamy if things break right. It somewhat reminds me July 89 event

My earliest weather memory. Had a buddy in Hamden that instinctively ran to the basement every time he heard thunder for years after that outbreak. Don't know how comparable tomorrow will be. Didn't '89 have a pretty classic EML?

Right.  Agreed.  I was looking through the SPC probabalistic to categories tables......it seems like it is nearly impossible to get a High Risk anymore.  Which is probably a good thing as with time when a High Risk day occurs, then the public will take it more seriously.

But for us in New England, the new categories eliminates any chances we had of ever seeing a High Risk Day.

Meh, there haven't been any threats thus far this year that have warranted one, IMO.

The Euro has very meager instability into New England. 1000-1500 J/KG at most. Leftover MCS really screws things up.

 

I would take 1500 J/kg and run with it. Given the shear, that combo would be fine for storms.

 

Obviously more CAPE would help ensure storms aren't torn apart by the shear, but I think we would get plenty of severe with 1500.

Wasn't really my point.  Was just saying that to qualify as a High Risk we either need a major tornado outbreak or a 60% chance of sig severe wind. 

 

Hail is an after thought.....can't ever qualify as a High Risk.

I don't really see how the new categories eliminate any chance SNE had at a high risk though in the future, as unlikely as it is.

That's further north than seemed to be talked about lately? No way with the MCS in the morning that it extends that far north in the early afternoon storms. I was thinking they'd keep it more in the SNE/ENY and maybe SNH/SVT....not as far up as MPV-BML.

 

Yeah, tad farther north than I was thinking for the enhanced. I had it about LEB to IZG in NH, so it's close.
