AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
325 AM CDT SAT MAY 18 2013
.DISCUSSION...
WATER VAPOR IMAGERY THIS MORNING DEPICTS DRIER MID LEVEL AIR
MOVING IN BEHIND THE SHORT WAVE RESPONSIBLE FOR THE WIDESPREAD
SHOWERS ON FRIDAY. ANOTHER WEAK WAVE WILL CLIP THRU MIDDLE TN
TODAY WHICH WILL INTERACT WITH INCREASING INSTABILITY TO KEEP SCT
CONVECTION GOING. CANNOT RULE OUT A PULSE SEVERE STORM JUST ABOUT
ANYWHERE IN THE CWA TODAY BUT THE GREATEST THREAT LOOKS TO BE IN
THE SOUTH/WEST. GUIDANCE TEMPS LOOK REASONABLE WITH AT LEAST A
LITTLE SUNSHINE EXPECTED.
MORE DIURNAL CONVECTION PSBL SUNDAY WITH EVEN BETTER INSTABILITY
PROGGED ACRS THE AREA. ONCE AGAIN A FEW STRONG/SEVERE STORMS ARE
POSSIBLE BUT NOT EXPECTING WIDESPREAD SEVERE. HAVE UNDERCUT THE
WARMER MAV TEMPS DUE TO HIGH MSTR CONTENT OF THE AIR/GROUND. DEEP
RIDGING TAKES OVER FROM SUN NGT INTO ERLY TUESDAY AND WITH A
DECENT CAP DVLPG HV KEPT THINGS DRY. WILL CONTINUE TO UNDERCUT
MAV/MEX HIGHS A CPL DEG.
PRECIP CHANCES WILL INCREASE TUESDAY THROUGH THE REST OF MID WEEK
AS VERY SLOW MOVING FRONT APPROACHES. FROPA STILL LOOKS LIKE WED
NGT INTO THURSDAY AND THAT IS THE PERIOD WHERE THE HIGHEST POPS
ARE CARRIED.
