AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MORRISTOWN TN
939 PM EDT MON JUN 9 2014

.DISCUSSION...
AFTER ANOTHER FAIR WEATHER DAY...MOSTLY CLEAR AND CALM CONDITIONS
ARE PREVAILING FOR NOW ACROSS THE EASTERN TENNESSEE VALLEY AND THE
SOUTHERN APPALACHIANS. TO THE SOUTH AND WEST...ALONG THE BORDER OF
ALABAMA...GEORGIA AND TENNESSEE A WEAK THETA-E AXIS/STATIONARY
FRONT REMAINS FIXED. TO THE SOUTHWEST OF THIS BOUNDARY...A
MODERATELY UNSTABLE ENVIRONMENT STILL EXISTS WHICH HAS ALLOWED
ANOTHER MCS TO FORM/HOLD TOGETHER ACROSS THE MID-SOUTH INTO THE
SOUTHERN TENNESSEE VALLEY. TO THE NORTHEAST AND EAST...A MUCH MORE
STABLE ENVIRONMENT EXISTS...WHICH WILL PROHIBIT MUCH IN THE WAY OF
THUNDER ACTIVITY ONCE THE AFOREMENTIONED SQUALL LINE APPROACHES
THE CENTRAL VALLEY LATER TONIGHT. THE LATEST RUN OF THE
HRRR INDICATES A LINE OF STRONG/SEVERE CONVECTION MAINTAINING
ITSELF WELL INTO SOUTHEAST TENNESSEE AND EVEN INTO SOUTHWEST NORTH
CAROLINA LATER TONIGHT BETWEEN 03-06Z...BEFORE IT SPREADS NORTHWARD
INTO THE CENTRAL AND NORTHERN VALLEY AND BEGINS TO DISSIPATE
BETWEEN 06-12Z.

THUS FOR THE FORECAST...HAVE INCREASED POPS ACROSS THE SOUTHERN
PLATEAU AND VALLEY TO LIKELY BETWEEN 03-09Z AND HIGH-END CHANCE
AREAWIDE AFTER 06Z. THINK THAT THE INTENSITY OF THESE STORMS AND
HOW LONG THEY CAN KEEP GOING WILL BE TIED TO A FAIRLY STOUT 850-700
MB JET WHICH IS ACCELERATING THE LINE TOWARD THE I-65 CORRIDOR AS
OF 9:30 PM EDT. WHILE SOME WEAKENING IS EXPECTED WITH THE LOSS OF
HEATING AND SLIGHTLY WEAKER INSTABILITY...THINK THAT THE THREAT FOR
STRONG TO ISOLATED SEVERE STORMS ACROSS THE SOUTHERN PLATEAU AND
VALLEY WILL BE POSSIBLE THROUGH 06Z OR SO. THE PRIMARY IMPACT WILL
BE GUSTY CONVECTIVE THUNDERSTORM WINDS AND SOME LOCALLY HEAVY
RAINFALL WITH THE LINE...AS WELL AS SOME GUSTY WINDS FOR AN HOUR OR
SO IN WAKE OF THE LINE. THUS...WILL ADD A MENTION OF THIS TO THE
HWO.

LOCATIONS ACROSS NORTHEAST TENNESSEE WILL LIKELY JUST EXPERIENCE
SOME SCATTERED LIGHT SHOWERS AROUND DAYBREAK AS THIS ACTIVITY
CONTINUES TO WANE. OTHERWISE...CLOUDS WILL EXPAND QUICKLY OVER THE
ENTIRE AREA BETWEEN 03-06Z WHICH WILL HELP MAINTAIN TEMPERATURES IN
THE 60S OVERNIGHT.
