AY 1 CONVECTIVE OUTLOOK 
   NWS STORM PREDICTION CENTER NORMAN OK
   0302 PM CDT WED JUN 04 2014

   VALID 042000Z - 051200Z

   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS THE OH AND TN RIVER
   VALLEYS TO THE CENTRAL APPALACHIANS...

   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS THE NORTHERN AND CENTRAL
   HIGH PLAINS...

   ...SUMMARY...
   STRONG TO SEVERE STORMS ARE EXPECTED TO DEVELOP ACROSS THE OHIO AND
   TENNESSEE VALLEYS TODAY THROUGH TONIGHT WITH A THREAT FOR MAINLY
   DAMAGING WINDS AND LARGE HAIL...ALTHOUGH AN ISOLATED TORNADO CANNOT
   BE RULED OUT. OTHER ISOLATED STRONG TO SEVERE STORMS WILL BE
   POSSIBLE ACROSS MUCH OF THE NORTHERN AND CENTRAL HIGH PLAINS THIS
   AFTERNOON AND EVENING.

   ...OH/TN VALLEYS...
   EARLY-MID AFTERNOON SURFACE ANALYSIS SHOWED AN AREA OF LOW PRESSURE
   CONTINUED TO MOVE EWD THROUGH THE LOWER OH VALLEY...AND AT 19Z WAS
   LOCATED IN EAST CENTRAL INDIANA.  A WARM FRONT EXTENDING ESEWD FROM
   THIS LOW HAD MOVED INTO SWRN OH TO WV...WHILE A TRAILING COLD FRONT
   HAS AND WILL CONTINUE TO ADVANCE SWD...WITH THE 19Z POSITION OF THIS
   BOUNDARY EXTENDING WSWWD FROM SRN IND/IL TO SOUTH OF STL IN MO.
   ENVIRONMENT ACROSS THE WARM SECTOR HAS BECOME MODERATELY-STRONGLY
   UNSTABLE THIS AFTERNOON GIVEN THE PRESENCE OF RICH MOISTURE /PW
   VALUES EXCEEDING 1.6 INCH AND SURFACE DEWPOINTS IN THE UPPER 60S TO
   LOWER 70S/ COMBINED WITH STRONG SURFACE HEATING AND ERN EXTENT OF
   STEEP LAPSE RATES.  GIVEN THESE FACTORS AND SEVERAL HIGH RESOLUTION
   CONVECTIVE ALLOWING MODELS SUGGESTING ONE OR MORE FORWARD
   PROPAGATING MCS STRUCTURES MOVING SEWD ACROSS WRN-CENTRAL KY INTO
   MUCH OF TN...THE 30 PERCENT SEVERE WIND PROBABILITY HAS BEEN
   EXPANDED SOME...WITH THE POTENTIAL FOR STRONG-SIGNIFICANT WINDS
   SPREADING ACROSS THIS REGION INTO THE EVENING.  TORNADO PROBABILITY
   HAS BEEN EXPANDED ACROSS THE OH VALLEY INTO SERN MO GIVEN GOOD
   HODOGRAPH CURVATURE WITH VERTICALLY VEERING WIND PROFILES.

   ...NRN AND CENTRAL HIGH PLAINS...
   SMALL ADJUSTMENT TO THE SLIGHT RISK AND ATTENDANT SEVERE
   PROBABILITIES HAS BEEN MADE ACROSS SERN WY TO ACCOUNT FOR HAIL/WIND
   THREATS INTO THIS AREA.

I was playing golf this evening and I'm not sure if the cloud I saw was a wall cloud or just a shelf cloud. This structure was west of the main rain shaft as the storm was moving southeast. The whole base was rotating very slightly. As it passed over a lot of scud clouds formed making it look even more ominous.

Any ideas as to which type of cloud this was? The pictures from my iPhone don't really do it justice.

Anyway the storms this afternoon and evening have been more discrete than just forming into a MCS as Morristown and other models were showing.

Afterwards the storm left a beautiful rainbow:

Post on MRX's FB page. They are pretty good at responding.

I sent email WCYB an email and they said it did resemble a wall cloud and Morristown said that it was a hint of a wall cloud but it was hard to tell. They said if nothing else it was a rain-free base and indicated a inflow/updraft location. Very cool nonetheless. Meanwhile if the line of storms in West KY misses us another line of storms is forming further north which may hit us in the early morning hours. The threat is not over with yet.

I made a more detailed post in the Ohio Valley sub-forum, but I was positioned right in front of that cell near Morton's Gap and I can vouch for a rotating wall cloud. Whatever it was became rain-wrapped, but I wouldn't rule out it being a weak tornado at one point. Not a good area to chase or observe with such a high density of trees.

Day 3 see text valid on Monday for the Mid South will become a slight risk tomorrow. If you believe the NAM/Euro it'll be a small MDT risk by Monday. We'll see what GFS does today. Unseasonably strong short-wave to eject from Texas into the Mid South on Monday. OFB will be in place ahead of any pre-frontal trough. I don't expect much trouble in eastern Tennessee; however, looks like a strong/severe storms day farther west in the heart of the Mid South and/or Mid Mississippi Valley on Monday.

 

Sorry I was off the board a lot for that great action June 4. I was on my way back from the Plains. We saw CG right in front of us down in deep south Illinois. It hit right next to the road. Smoldering hole left in some guy's yard. Did not wanna take pix but it was pretty wild. When we first approached it looked like when someone burns leaves. However, no leaf pile, raining very hard, and brown/black smoldering depression in grass. No tornado June 4, but that lightning strike was beyond incredible. Cheers!

We like to welcome visitors with good storms! Saturday afternoon was my daughter's second birthday party so I was out of touch after my morning post. That little surprise was a classic outflow boundary sleeper set-up. Jet stream energy was meager but there was plenty down around 500 mb. Plus the jet stream was enough back where it initiated along the Mississippi River. Finally low level turning was enhanced on the outflow boundary. Saturday rocked!

 

I still think Monday will go; and, Saturday was a kind of hint to be on the lookout. NAM wants to do bows/segments, but it has been stuck in that mode for a while. Perhaps summer climo? However we see how things want to start out as supercells as May type upper systems come through in June. Monday turning and speed shear with height will be excellent from surface to 500 mb; and, I expect plenty of outflow boundaries from weekend festivities. Only issue is veer-back up toward 200 mb along with lighter winds. OK/AR may be bogged down in previous convection issues. Personally I expect an outflow boundary to go, well east of that mess, in the Delta on Monday, tracking into the rest of the Mid South. June boom continues..

That is crazy. Glad you made it out in one piece! Thanks for stopping by.

Just about time to rock and roll in Memphis and West Tenn. Severe bow echo coming out of Ark. Book-end of line on radar is appropriately warned tornado in east-central Ark. Outflow boundary remains in/near Memphis. OFB will help to focus energy and keep the line of storms quite intense. Should be mainly very high straight line winds; but, one might catch a brief spin-up in the Memphis metro and West Tenn. Be safe!

Nearly east-west outflow OFB noted in West Tenn. Cells along it are starting to rotate. I'd have gone 50/20 or even 60/20 on the TOR probs. Oh but the high-res models have been choking; and, as the HRRR goes so the SPC goes. These models are suffering climatology bias, trying to depict a summer pattern with a spring strength short-wave.

 

Mississippi cells are suspect too, but they don't have the low level turning of an OFB to work with; plus, not quite as much upstairs. That said, CAPE is high in Miss. Otherwise we have the big red bow behind all of the supercells. Will deal with tomorrow after morning OFBs become established mid-morning.

 

For now, today would have been a good day to visit Memphis and chase east back toward home. If you liked Saturday, EF-1 tornado confirmed by both PAH/MEM, you're gonna love today!
