Sounds like they think the storm mode may inhibit the potential from being fully realized

 

 

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1204 AM CST WED FEB 24 2016

VALID 241200Z - 251200Z

...THERE IS A MDT RISK OF SVR TSTMS FOR PORTIONS OF CNTRL NC AND FAR
S-CNTRL VA...

...THERE IS AN ENH RISK OF SVR TSTMS SURROUNDING THE MDT RISK FROM
FAR NE SC NEWD INTO SE VA...

...THERE IS A SLGT RISK OF SVR TSTMS FROM THE CNTRL FL PENINSULA
NEWD INTO THE DELMARVA...

...THERE IS A MRGL RISK OF SVR TSTMS OVER PORTIONS OF FL AND THE ERN
SEABOARD...

...SUMMARY...
STRONG TO SEVERE THUNDERSTORMS CAPABLE OF DAMAGING WINDS ARE
FORECAST FROM THE MID-ATLANTIC STATES SOUTHWARD THROUGH THE
CAROLINAS AND INTO FLORIDA TODAY. HIGHEST THREAT FOR SEVERE WEATHER
WILL BE FROM CENTRAL NORTH CAROLINA NORTHEASTWARD INTO FAR SOUTHEAST
VIRGINA.

...SYNOPSIS...
MATURE CYCLONE IS EXPECTED TO BE CENTERED NEAR THE CONFLUENCE OF THE
OH AND MS RIVERS AT THE BEGINNING OF THE PERIOD...WITH A GENERALLY
NEWD MOTION ACROSS THE OH VALLEY AND INTO THE LWR GREAT LAKES
EXPECTED THROUGHOUT THE DAY AND OVERNIGHT. POWERFUL MID-LEVEL JET
ACCOMPANYING THIS SYSTEM /WITH 500-MB WINDS OVER 100 KT/ WILL PIVOT
AROUND THE LOW...RESULTING IN STRONG FORCING FOR ASCENT ACROSS THE
CAROLINAS AND MID-ATLANTIC DURING AFTERNOON. CONTINUED NWD MOTION OF
THE JET WILL TAKE THIS STRONG FORCING INTO THE NORTHEAST DURING THE
EVENING AND OVERNIGHT. SURFACE LOW ASSOCIATED WITH THIS SYSTEM WILL
MOVE FROM ITS INITIAL POSITION OVER WRN KY NEWD ACROSS THE OH VALLEY
AND LWR GREAT LAKES REGION WHILE DEEPENING. WLY POSITION OF THIS
SURFACE LOW COUPLED WITH THE STRONG LOW-LEVEL FLOW ASSOCIATED WITH
THE MATURE CYCLONE WILL RESULT IN STRONG WARM AIR AND MOISTURE
ADVECTION ACROSS CNTRL AND ERN PORTIONS OF THE MID-ATLANTIC AND
CAROLINAS.

...MID-ATLANTIC...CAROLINAS...
00Z SOUNDINGS AT GSO...RNK...AND IAD SAMPLED THE WEDGE FRONT WELL
WITH TEMPERATURES IN THE 40S AND A LOW-LEVEL INVERSION IN PLACE TO
ABOUT 850 MB. GIVEN THE STRENGTH OF WAA EXPECTED DURING THE
DAY...THE TYPICALLY STUBBORN WEDGE FRONT WILL LIKELY ERODE BY THE
EARLY AFTERNOON...REPLACED BY WARM AND MOIST AIRMASS CHARACTERIZED
BY TEMPERATURES IN THE UPPER 60S/LOW 70S...DEWPOINTS IN THE MID
60S...AND MLCAPE AROUND 500-1000 J PER KG. THIS UNSTABLE AIRMASS IS
EXPECTED TO BE IN PLACE AHEAD OF THE FORCING FOR ASCENT ASSOCIATED
WITH THE APPROACHING MID-LEVEL JET.

STRONG LOW-LEVEL WIND FIELDS /70 KT AT 850 MB/ WILL LIKELY BE IN
PLACE BY THE LATE MORNING WITH THE STRONG MID/UPPER LEVEL WINDS
FOLLOWING BY THE EARLY AFTERNOON. AS A RESULT...AN IMPRESSIVE
KINEMATIC ENVIRONMENT WILL EXIST DURING THE AFTERNOON. GUIDANCE
SUGGESTS A LARGE AREA WILL 0-6 KM BULK SHEAR GREATER THAN 60 KT WITH
MEAN STORM MOTIONS LIKELY OVER 50 KT ACROSS MUCH OF THE REGION AS
WELL. THERE IS SOME BACKING IN THE MID/UPPER LEVELS OF THE WIND
PROFILES...SUGGESTING THE PRIMARY STORM MODE WILL BE BOWING LINE
SEGMENTS/CLUSTERS. A FEW DISCRETE SUPERCELLS ARE ALSO POSSIBLE.

GIVEN THE STRENGTH OF THE FLOW AND THE ANTICIPATED STORM MODE...
THE PRIMARY SEVERE THREAT WILL BE STRONG WIND GUSTS...WITH SOME
GUSTS OVER 65 KT POSSIBLE. A STRONG TORNADO OR TWO IS ALSO POSSIBLE
GIVEN THE STRENGTH OF THE LOW-LEVEL FLOW AND EXPECTATION OF AT LEAST
MODEST SURFACE-BASED INSTABILITY.

That line in the FL Panhandle/SW GA isn't a line anymore. Looks to be breaking into semi-discrete supercells.

Yup. Also a bunch of cells coming in off the Gulf that are in a very favorable environment. Still amazes me that we're talking about tornadic supercells in the middle of a February night.

 

Time to sleep.

Garbage event around here.

 

Back to bed I go.  We never get anything fun around these parts.  Again. can't wait to leave this stupid area.  Southeast garbage.  Just enough lightning to ruin a lake day always.  And always just enough warmth/wedge erosion in CAE to ruin Wintry weather.

Wedge holding strong here! Temp has only risen 4 degrees since 11pm. Currently 51 and have not had a thunderstorm all night! Timing has helped, the wind energy for the rest of today and through tomorrow , combined with soggy soils, will probably down a few trees

 

Wedge holding here for now; 44 degrees IMBY but was awoken by thunder last night with some downpours.

Not sure it was fun for the people hit by a tornado.

I must be right under the warm front now, temp was 60 at my house east of Greenville and at the plant it was 54, winds shifting SE at the airport how far inland this warm front gets will make or break the event in NC today.....

 

also at least IMBY we have had tons of rain this month over 10" and the ground is soaked, even the showers we have had has left standing water in yards etc.....winds will go for 45-50 mph today without storms and there may be a lot of trees down, it wont take much with the ground this wet.

Good luck to all the east coast members in the path of severe weather today. Yesterday was a wild ride on the gulf coast. Mother Nature and her miracles never cease however as according to local media reports there have been no serious injuries or fatalities from the Pensacola tornado. Thoughts & Prayers to the families affected west of us. As posted before thank you to all, especially those who came from other sub forums to input analysis.

Really concerned for my backyard as we seem to be in the most favored locale for tornadic supercells early this afternoon.

 

Depends on the warm front, right along and south of it gonna be nasty.....should be a few cells anchored to it and moving right along it that could be the worst ones of the day.....so where ever it is around 12-12 today should be in trouble and then from there east the cells will have prime conditions
