2014 Severe Storm season


downeastnc

Recommended Posts

Severe weather season in the SE is OVER. Or at least tornado season is. It's extremely rare to have tornadoes in the summer months in the south, unless it's the product of a tropical system.

Yes however I cannot recall if it was Accuweather or the Weather Channel that covered a great approximate three minute discussion on this but due to several contributing factors they stated that severe weather season would become rampant this year from the June-July timeframe rather than the traditional April-May timeframe. Be mindful of this maybe not so much for your neck of the woods but just watching the MCS and derecho talks starting to heat up for today and tomorrow it may be coming to fruition. Just some food for thought.

GSP has a good write up in their AFD . They say if the MCS misses to our north on Wednesday night, that the NAM shows cape of 4000+ in our forecast area ahead of the front on Thur. ! That's unusually high for our area and could lead to a very severe outbreak of damaging storms and they mention isolated tornado threat!

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.SCATTERED TO NUMEROUS THUNDERSTORMS...SOME PROBABLY SEVERE WITHDAMAGING WIND GUSTS AND HAIL...ARE EXPECTED TO ACCOMPANY A COLDFRONT THROUGH CENTRAL NC ON THURSDAY.

 

Looks like the system that is in the midwest today could affect us. WRAL said we will have a moderate risk Thursday for severe storms.

Moderate risk? I think you mean slight chance.

I just read that write up.  You don't see them talking something up and using that wording very often.  Here is the c&p for everyone to read.

 

THE THURSDAY FORECAST DEPENDS MUCH UPON WHAT HAPPENS WED NIGHT/THU

MORNING...AS CONVECTION WILL BE ONGOING SOMEWHERE WITHIN THE

MID-ATLANTIC AND SURROUNDINGS AREAS. IF THE ATMOSPHERE OVER THE

WESTERN CAROLINAS REMAINS RELATIVELY UNDISTURBED BY THIS AM

CONVECTION...WE FACE A POTENTIALLY VOLATILE SITUATION THU

AFTERNOON...AS THE COLD FRONT SAGS INTO THE AREA. FORECAST SOUNDINGS

ARE QUITE OUTLANDISH FOR OUR AREA...WITH CAPE IN SOME NAM SOUNDINGS

EXCEEDING 4000 J/KG. ALTHOUGH PROFILES ARE GENERALLY UNIDIRECTIONAL/

VEERED...SHEAR IS MORE THAN RESPECTABLE...ESPECIALLY FOR EARLY

JUNE...WITH DEEP LAYER BULK SHEAR EXCEEDING 35 KTS...AND LOW LEVEL

SHEAR IN EXCESS OF 25 KTS. GIVEN FORECAST DCAPE IN EXCESS OF

1000...INTENSE CONVECTION COULD ORGANIZE ALONG STRONG COLD

POOLS...RESULTING IN A POSSIBLE HIGH END DOWNBURST THREAT...WHILE

CAPE IN EXCESS OF 1000 J/KG IN THE -10C TO -30C LAYER WOULD ALSO

SUPPORT THE POTENTIAL FOR VERY LARGE HAIL. FAIRLY LONG/STRAIGHT

HODOGRAPHS WITHIN HIGH/EXTREME CAPE ENVIRONMENT WOULD ALSO SUPPORT A

GOOD POTENTIAL FOR DISCRETE/SPLITTING SUPERCELLS...WITH AN ISOLATED

TORNADO THREAT POSSIBLE WITH ANY CELL DEVIATING STRONGLY FROM THE

MEAN FLOW. AGAIN...ALL POSSIBLE ONLY IF MORNING CONVECTION DOESN/T

STABILIZE THE ENVIRONMENT.

Does not look like a good severe setup to me.  Hopefully, we can get some legitimate thunder at least.

 

Really depends on timing and how much of the MCS that fires NW of here today gets in here and leave trash around to kill instability.....SPC dropped all slight risk for the SE so they must think we don't get a lot of sun tomorrow to juice it up.

Well not much in the way of cloud cover perhaps a return to a slight risk is in order for central and eastern NC......its muggy and lots of midday sun should put us in the highest cape values we have seen so far and with decent lapse rates even the not so great shear should be enough to see some action especially 12-5ish as those storms will have the most to work with.

LI -4 already and cape is already building and the mid level lapse rates are high for here this time of the year so if we can keep a lot of crud from firing late morning and trashing it up we might see some pretty decent storms especially Fayetteville and up and east of I-95.

Cells firing around Raleigh and the instability is pretty high so we should see these spread the best chance to get any real severe stuff will be the next 3-4 hrs during peak heating when a storm has the most to work with and even then its going to be pulse type storms I bet with the shear so weak.
