March 31st Severe/Tornado Event


SmokeEater

Recommended Posts

Somewhat high end severe seems likely this afternoon and evening in AL and MS, meso discussion out from NE LA to NE MS for a tornado watch being likely.

MESOSCALE DISCUSSION 0306

NWS STORM PREDICTION CENTER NORMAN OK

0130 PM CDT THU MAR 31 2016

AREAS AFFECTED...CNTRL/NERN LA...CNTRL AND NRN MS

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY

VALID 311830Z - 312030Z

PROBABILITY OF WATCH ISSUANCE...80 PERCENT

SUMMARY...A SEVERE THREAT WILL LIKELY DEVELOP FROM CNTRL AND NERN LA NEWD INTO CNTRL AND NRN MS. TORNADOES...WIND DAMAGE AND HAIL WILL BE POSSIBLE ACROSS PARTS OF CNTRL AND NRN MS. ISOLATED LARGE HAIL AND WIND DAMAGE WILL BE POSSIBLE SWWD ACROSS WRN MS INTO NERN AND CNTRL LA. WW ISSUANCE WILL LIKELY BE NEEDED ACROSS THE REGION THIS AFTERNOON.

DISCUSSION...LATEST SFC ANALYSIS SHOWS A DISTINCT CORRIDOR OF

LOW-LEVEL MOISTURE LOCATED FROM ERN LA NNEWD ALONG THE MS RIVER INTO WRN TN. SFC DEWPOINTS ALONG THIS CORRIDOR RANGE FROM THE MID 60S TO THE LOWER 70S F AND MLCAPE IS ESTIMATED FROM NEAR 1500 J/KG IN NERN LA TO AROUND 750 J/KG IN NERN MS. OVER THE LAST HOUR...RADAR TRENDS SHOW CONVECTION TRYING TO INITIATE IN WRN MS BUT THIS PROCESS MAY TAKE AN HOUR OR SO. THE HRRR IS IN AGREEMENT WITH THIS THINKING...SUGGESTING THAT THUNDERSTORMS WILL DEVELOP IN NW MS AND NERN LA IN THE 19Z TO 20Z TIMEFRAME WITH A GRADUAL INCREASE IN

CONVECTIVE COVERAGE LATE THIS AFTERNOON. REGIONAL WSR-88D VWPS IN CNTRL AND NERN MS SHOW 0-6 KM SHEAR OF 60 KT WITH 0-3 KM STORM

RELATIVE HELICITIES NEAR 350 M2/S2. THIS COMBINED WITH SFC SSELY

FLOW ACROSS NERN MS WILL BE FAVORABLE FOR SUPERCELLS WITH TORNADOES AND WIND DAMAGE LATER THIS AFTERNOON. FURTHER TO THE SOUTHWEST ACROSS NERN LA AND WRN MS...SFC WINDS ARE GENERALLY FROM THE SOUTHWEST SUGGESTING THAT THE TORNADO THREAT WILL BE LESS.

STILL...STEEP MID-LEVEL LAPSE RATES AND STRONG DEEP LAYER SHEAR OVER

NE LA AND WRN MS WILL FAVOR SUPERCELLS WITH ISOLATED LARGE HAIL AND WIND DAMAGE.

bango dude!

Everything is going as expected Gulf storms robbing rain totals for NC today and clouds keeping instability at bay for late tonight. Still will see a few gusty wet storms tonight but widespread severe not expected just isolated.

Looks like a chance of widely scattered birds, with a slight chance of healing skies.

SOME BACKING AND STRENGTHENING OF WINDS AOB 1 KM AGL. THIS

ENLARGEMENT TO THE LOW-LEVEL HODOGRAPH IS YIELDING 0-1 KM SRH AROUND

250-300 M2/S2. WITH MIDDLE TO UPPER 60S SURFACE DEW POINTS HAVING

OVERSPREAD ALL BUT NERN AL AS AN EARLIER LARGE-SCALE CONVECTIVE
