AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
1045 AM CDT WED MAY 14 2014

.UPDATE...

LARGE AREA OF SHOWERS AND STORMS THAT MOVED THROUGH THE MID STATE
EARLIER THIS MORNING NOW WELL OFF TO THE NORTH AFTER DROPPING
FAIRLY WIDESPREAD 1 TO 2 INCH RAINFALL TOTALS. ADDITIONAL SHOWERS
AND STORMS HAVE ALREADY FORMED AND NOW ENTERING THE UPPER
CUMBERLAND REGION AND SOUTHWEST MID TN. WITH STATIONARY FRONT
ACROSS WESTERN ZONES AND DEEPENING SURFACE LOW MOVING NORTHWARD
THROUGH THE AREA PROVIDING A FOCUS FOR CONVECTION...EXPECTING OFF
AND ON SHOWERS AND STORMS AREAWIDE THE REST OF TODAY. HIGHEST
COVERAGE LOOKS TO BE GENERALLY AROUND THE I-65 CORRIDOR TO EAST
OF FRONTAL BOUNDARY...WITH SOMEWHAT LESS COVERAGE FAR WEST AND ON
PLATEAU. SEVERE RISK STILL APPARENT ESPECIALLY THIS AFTERNOON WITH
ADDITIONAL SURFACE HEATING...AND HAVE ALREADY SEEN SOME WEAK
ROTATION IN SOME OF THE STRONGER UPDRAFTS. BEST CHANCE FOR SEVERE
STORMS WILL BE ACROSS THE EASTERN HALF OF THE CWA WHERE
TEMPERATURES ARE ALREADY IN THE MID 70S TO AROUND 80 UNDER MOSTLY
SUNNY SKIES. DAMAGING WINDS AND LOCALIZED FLOODING WILL BE THE
MAIN THREATS WITH ANY STRONGER STORMS TODAY...BUT CANNOT RULE OUT
AN ISOLATED TORNADO AS LLJ CONTINUES TO STRENGTHEN. HAVE ADDED
MENTION OF SEVERE STORMS AND LOCALLY HEAVY RAINFALL TO GRIDS AND
ZONES FOR REST OF TODAY AS WELL AS RAISED POPS. UPDATED PRODUCTS
ALREADY SENT.

.PREV DISCUSSION... /ISSUED 645 AM CDT WED MAY 14 2014/

AVIATION...
UNSETTLED WEATHER PATTERN IN STORE FOR THIS TAF PD AS A SLOW
MOVING COLD FRONTAL BOUNDARY PUSHES TOWARD THE AREA. AS A SFC LOW
DEVELOPS ALONG THE BOUNDARY AND MOVES NORTHWARD...SHOWERS AND
TSTMS WILL CONTINUE TO DEVELOP AND MOVE NORTHWARD ACROSS MIDDLE TN.
AS WE GET BEYOND 00Z...AREAL COVERAGE OF THE PRECIPITATION SHOULD
DECREASE.

PREV DISCUSSION... /ISSUED 352 AM CDT WED MAY 14 2014/

DISCUSSION...
TROUGH INVERSION BEGINNING TO SETUP ACROSS THE MID AND DEEP SOUTH.
LATEST SFC ANALYSIS PLACES THE TROUGH AXIS ACROSS SRN MS AND EXTENDS
NORTHWARD TOWARD MIDDLE TN. MEANWHILE...UPPER TROUGH WILL CONTINUE
TO DEVELOP ACROSS THE NATIONS INTERIOR AND WILL BEGIN TO MOVE SLOWLY
EASTWARD. AS THE STRONGER UPPER DYNAMICS BEGIN TO OVERLAP THE
DEVELOPING SFC TROUGH...CYCLOGENESIS IS EXPECTED TO COMMENCE LATER
TODAY WITH THE SFC LOW DEVELOPING ACROSS MIDDLE TN THIS AFTERNOON.
THE SFC LOW WILL CONTINUE TO TRACK OFF TO THE NORTH AND INTENSIFY
THIS EVENING. THIS WILL ACT TO KEEP THE BETTER SHEAR TO OUR
NORTH. NEVERTHELESS...THE DEEP SOUTHERLY MOIST FLOW AND NEGATIVE
SHOWALTER VALUES MEANS SHOWERS AND TSTMS FOR THE AREA TODAY. POPS
WILL BE IN THE LIKELY TO CATEGORICAL LEVEL.

TONIGHT...SHOWERS AND TSTMS WILL CONTINUE INTO THIS EVENING AS THE COLD
FRONT APPROACHES. THE WIND SHIFT LOOKS AS THOUGH IT WILL TAKE
PLACE JUST AFTER MIDNIGHT. AT THAT TIME...THE STRONG UPPER TROUGH
AXIS WILL BE ON A SLOW APPROACH WITH THE MAIN VORT CENTER STILL TO
OUR WEST. SOME DESCENT POS VORT ADVECTION WILL BE IN PLACE AND
WILL CONTINUE WITH A GOOD CHANCE OF SHOWERS FOR LATE TONIGHT.

COOLER WEATHER WITH A CONTINUING LOW CHANCE OF SHOWERS WILL CONTINUE
FOR THURSDAY AND FRIDAY. TEMPERATURES WILL DROP TO A GOOD 10 TO 15
DEGREES BELOW NORMAL...COMPLIMENTS OF THE STRONG AND SLOW MOVING
UPPER TROUGH.

IN THE EXT FCST...UPPER TROUGH AXIS WILL FINALLY MOVE EAST OF TN BY
THIS WEEKEND. HOWEVER...HEIGHT VALUES ARE STILL RATHER FLAT AND THE
BELOW NORMAL TEMPS WILL REMAIN INTO SUNDAY. LOW RAIN CHANCES WILL
PERSIST AS WELL AS A FEW WEAK IMPULSES TRAVERSE THE AREA.

BY THE VERY END OF THE EXTENDED...A STRONG UPPER HIGH WILL ATTEMPT
TO GRAB A FOOTHOLD ACROSS THE LOWER MS VALLEY. 850 MB TEMPS WILL
SOAR ALONG AND JUST NORTH OF THE UPPER HIGH WITH THERMAL RIDGING
ATTEMPTING TO SPREAD OUR WAY. BY TUESDAY...HIGHS BACK UP INTO THE
MID 80S LOOKS LIKELY.
