AREA FORECAST DISCUSSION

720 PM CDT SUN APR 6 2014

...TORNADO WATCH 65 IN EFFECT UNTIL 3 AM CDT MONDAY MORNING...

.MESOSCALE UPDATE...JUST A QUICK UPDATE FOR THE TORNADO WATCH FOR
OUR ENTIRE AREA INCLUDING ADJACENT BAYS. UPDATED ZONES AND COASTAL
WATERS FORECAST OUT SOON.

A SURFACE WARM FRONT CURRENT NEAR/ALONG THE I-10 CORRIDOR IS SLOWLY
LIFTING NORTHWARD. WARM MOIST AND UNSTABLE AIR IS MOVING INLAND
GRADUALLY. LOCAL VERTICAL WIND SHEAR AND THERMODYNAMIC INSTABILITY
PROFILES ARE SUPPORTIVE OF TORNADO-PRODUCING MESOCYCLONES...SOME OF
WHICH MAY PRODUCE ISOLATED TORNADOES UP TO EF-2 INTENSITY. ONE MAIN
AREA OF CONCERN FOR ISOLATED TORNADO OCCURRENCE IS WEST OF THE I-65
CORRIDOR THIS EVENING (ESPECIALLY OVER SOUTHEAST MISSISSIPPI). THE
LATTER IS WHERE TORNADOES WILL MOST LIKELY DEVELOP BEFORE THE THREAT
SHIFTS MOVING FURTHER EAST DURING THE OVERNIGHT HOURS.

A SQUALL LINE IS EXPECTED TO FORM LATER TONIGHT AND IT TOO WILL
CONTAIN EMBEDDED TORNADOES ALONG WITH DAMAGING WINDS (AND LARGE HAIL)
ASSOCIATED WITH BOW ECHOES. AT THIS TIME...CURRENT THINKING IS THAT
THE SQUALL LINE WILL MOVE INTO OUR SOUTHEAST MISSISSIPPI COUNTIES
AROUND SUNRISE AND STILL BE WEST OF THE I-65 BY MID MORNING. THE
THUNDERSTORM LINE WILL MOVE EAST OF THE I-65 CORRIDOR DURING THE
EARLY AFTERNOON. THE THREAT SHOULD END ALTOGETHER BY MID AFTERNOON
INCLUDING POINTS AS FAR EAST AS GREENVILLE TO DESTIN.

FINALLY...THE FLASH FLOODING RISK IS VERY HIGH ALONG AND NORTH OF THE
HIGHWAY 84 CORRIDOR (ESPECIALLY) WHERE THE HEAVIEST RAINS HAVE FALLEN SINCE LAST
EVENING. AS STORMS DEVELOP AND REPEATEDLY MOVE OVER THE SAME LOCATION
EXPECT 6" OR MORE OF WATER TO FLOW ACROSS THE ROADS AND POSSIBLE ROAD
CLOSURES. THE FLASH FLOOD THREAT MAY DEVELOP SOUTHWARD THIS EVENING
AND OVERNIGHT. /23 JMM
