AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
1108 AM CST FRI MAR 2 2012

.MESOSCALE UPDATE...ROTATING STORMS FIRED UP THIS MORNING OVER OUR
EASTERN COUNTIES...IN A STRONG 850 THETA E AXIS. THIS CONVECTION
WILL MOVE EAST OF THE AREA SOON..AND WE HAVE A BREAK IN OUR
WARNING ACTIVITY FOR PROBABLY 2 HOURS. GUSTY SSW WINDS TO 40 MPH
WILL DEVELOP ACROSS THE MID STATE UNDER PARTLY SUNNY SKIES. A WIND
ADVISORY WILL REMAIN IN EFFECT THROUGH THE DAY.

ISOLATED TO SCATTERED CELLS ARE EXPECTED TO DEVELOP FROM THE WEST
EARLY AFTERNOON...WITH RAPID INTENSIFICATION. WE REMAIN UNDER A
HIGH RISK ALONG AND NORTH OF I 40...AND A MODERATE RISK SOUTH OF I
40. DAMAGING WINDS...LARGE HAIL AND TORNADOES ARE ALL POSSIBLE. THE
COVERAGE OF STORMS WILL INCREASE RAPIDLY AFTER 3 PM...WITH A QLCS
EVENTUALLY DEVELOPING. THE GREATEST CONCENTRATION OF HEAVY STORMS
WILL COME TOGETHER OVER EASTERN SECTIONS...AND THE RAIN COULD BE
QUITE HEAVY FOR A WHILE. A FLASH FLOOD WATCH WILL BE ISSUED FOR
THIS POTENTIAL.

13

&&

.PREV DISCUSSION... /ISSUED 918 AM CST FRI MAR 2 2012/

UPDATE...VERY BUSY ALREADY WITH STORMS FIRING UP...WATCH COMING
SOON...AND VARIOUS UPDATES NEEDED.

FIRST UPDATE ALREADY OUT TO EXPAND WIND ADVISORY ALL ZONES AND
ADJUST VARIOUS TRENDS. FORECAST WIND FIELDS SUPPORT WIDESPREAD
GRADIENT GUSTS OVER 35 OR 40 MPH ACROSS THE AREA. WE ARE ALSO
CONSIDERING A FLASH FLOOD WATCH EAST HALF.

13

PREV DISCUSSION... /ISSUED 736 AM CST FRI MAR 2 2012/

UPDATE...
SPC HAS UPGRADED OUR NORTHERN AREA TO A HIGH RISK. ASSOCIATED
HATCHED 30% AREA IS NOTED AS WELL FOR EF-2 TORS OR STRONGER. WILL
THEREFORE UPDATE THE ZONES WHICH NOW CALL FOR STRONGER WORDING.

PREV DISCUSSION... /ISSUED 609 AM CST FRI MAR 2 2012/

UPDATE...FOR 12Z AVIATION DISCUSSION.

AVIATION...12Z AVIATION DISCUSSION.
THE POTENTIAL FOR SVR TSTMS DEVELOPMENT WILL CONTINUE THRU AT LEAST
03/02Z AT MOST TAF SITES...AND BELIEVE OVERALL BEST WINDOWS WILL BE
02/18Z-02/22Z CKV...02/19Z-02/23Z BNA...02/22Z-03/02Z CSV. HAVE
MENTIONED SFC GUSTS TO 50KTS AT THESE LOCATIONS DURING THESE TIME
PERIODS. STORMS SHOULD DIMINISH W TO E AFTER 03/01Z-03/03Z...WITH
CEILING EROSIONS BETWEEN 03/05Z-03/07Z.

PREV DISCUSSION.../ISSUED 412 AM CST FRI MAR 2 2012/ WARM FRONT
CURRENTLY LIFTING NORTHWARD ACROSS THE MID STATE. DEWPOINT
GRADIENT IS QUITE IMPRESSIVE WITH 36F AT BNA AND 62F AT HSV AT 2
AM. WEAK SPEED CONVERGENCE WILL ACCOMPANY THE WARM FRONT PASSAGE.
THUS...A FEW SHOWERS WILL SPREAD NORTHWARD THIS MORNING.

DURING THE DAY TODAY...PROG SOUNDINGS SHOWING VERY DRY AIR FROM
700MB UPWARD THROUGH MUCH OF THE DAY. MEANWHILE...LOWER LEVELS WILL
BECOME INCREASINGLY UNSTABLE. WITH THE OVERALL AIRMASS DEPTH BEING
ON THE DRY SIDE...IT LOOKS AS THOUGH MORE IN THE WAY OF SCATTERED
CONVECTION CAN BE EXPECTED THROUGH THE MORNING AND EARLY AFTERNOON.
THEN...AS WE WARM UP...THE ADDED INSTABILITY WILL WORK IN FAVOR OF
MORE LINEAR AND ORGANIZED CONVECTION. THE POSITIONING OF THE COLD
FRONT LOOKS AS THOUGH IT WILL MOVE THROUGH THE NASHVILLE AREA AROUND
7 OR 8 PM TONIGHT. MUCH OF THE FORCING WILL RESIDE A FEW HOURS AHEAD
OF THE FROPA. SUMMING THIS ALL TOGETHER...IT LOOKS TO ME AS THOUGH
SCATTERED CONVECTION WILL OCCUR ACROSS MIDDLE TN THIS MORNING AND
INTO THE EARLY AFTERNOON. THEN...COVERAGE WILL INCREASE ACROSS
EASTERN ZONES IN THE AFTERNOON AS THE CAP BUSTS. MY POPS FOR TODAY
WILL RANGE FROM 50 ACROSS THE WEST TO 70 PLATEAU. I WILL LEAN
HEAVILY TOWARD ISC GRIDS AND ADJUST ACCORDINGLY.

AS FOR THE SEVERE POTENTIAL...WITH TEMPS EXPECTING TO WARM UP TO
NEAR 80 FOR MUCH OF THE AREA WEST OF THE PLATEAU...INSTABILITIES IN
THE LOWER LEVELS WILL INCREASE QUITE SUFFICIENTLY TO SUPPORT THE
SEVERE STORM DEVELOPMENT. FURTHERMORE...50-55 KT LOW LEVEL JET WITH
0-3KM HELICITY VALUES AROUND 250 - 300 IN THE LATE AFTERNOON WILL
PROVIDE AMPLE LOW LEVEL SHEAR. WILL THEREFORE INCLUDE THE MENTION OF
SEVERE STORMS IN THE FCST...WITH AFT WORDING USED...LATE AFT/EARLY
EVE PLATEAU. VERY LOW LCL LEVELS WILL SUPPORT ISOLATED TORNADIC
CONDITIONS.

AGAIN...AT THIS POINT IN TIME...THE TIMING OF THE SEVERE WEATHER
LOOKS AS THOUGH IT WILL OCCUR FROM NOON-4PM WEST...2P-6P
CENTRAL...AND 4P-8P FOR THE EASTERN PLATEAU. SCT SEVERE CONVECTION
WEST...WITH LINEAR FORMATION AND BETTER ORGANIZATION ACROSS OUR EAST
AS WE GAIN ADDITIONAL HEATING.

OTHERWISE...TIGHT GRADIENT TODAY WITH WIND ADVISORY CRITERIA ALONG
OUR WESTERN QUARTER. WILL GO AHEAD AND INCLUDE A WIND ADVISORY FOR
THAT AREA.

AFTER TONIGHT'S FROPA....COOLER AND MORE SEASONAL WEATHER WILL
RETURN. A QUICK MOVING DISTURBANCE WITH THE NW FLOW WILL BRING A
CHANCE OF SHOWERS FOR SUNDAY.

FOR THE NEAR TERM TEMPS...WILL UNDERCUT THE MAV HIGH TEMPS THROUGH
SUNDAY BY A FEW DEGREES.

IN THE EXT FCST...WE WILL HAVE DRY WEATHER WITH A WARMING TREND AS
WEAK UPPER RIDGING DOMINATES. NEXT STORM SYSTEM WILL NOT EFFECT THE
AREA UNTIL NEXT WEEKEND.

AGAINST THE MEX GUIDANCE...I WILL INCLUDE A SLIGHT UNDERCUT FOR THE
FIRST HALF OF THE EXTENDED.
