Severe Thunderstorm Warning 60, NWS Huntsville, AL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
305 PM CDT FRI MAY 17 2013

.DISCUSSION...
A TRICKY FCST SHAPING UP WITH TIMING/COVERAGE OF PCPN FOR THIS
WEEKEND...NOT TO MENTION TEMPS AND TIMING OF A CDFNT FOR THE MIDDLE
OF NEXT WEEK. FOR NOW WILL GO WITH A BLEND OF NAM/GFS FOR THIS FCST.

FOR THE REST OF THIS AFTN/EVENING...A SLOW MOVING UPPER TROF WILL
HAVE ENOUGH LOW LEVEL SHEAR/INSTABILITY FOR SOME STRONG TO SVR STORMS
WITH DAMAGING WINDS THE MAIN THREAT. HOWEVER CANT RULE OUT LARGE
HAIL...LOCALIZED HVY RAIN/FLOODING AND A FEW WEAK TORNADOES. THE SVR
WX THREAT SHOULD BEGIN TO DIMINISH LATER THIS EVENING...ESPECIALLY
AFTER THE LOSS OF DAYTIME HEATING. OTHERWISE ANOTHER MUGGY NIGHT WITH
OVERNIGHT LOWS IN THE MID 60S. WILL KEEP HIGH POPS TONIGHT ACROSS THE
TN VALLEY DUE TO THE SLOW MOVING UPPER TROF.

SATURDAY...THE AXIS OF THE UPPER TROF WILL BE ALONG THE AL/GA LINE
ARND 12Z. HOWEVER MODELS SHOW A WEAK WAVE ARND 8H WHICH WILL KEEP THE
CHC OF SHRA/TSRA THRU THE AFTN. HOWEVER BY LATE AFTN/EVENING THE
SHRA/TSRA ACTIVITY SHOULD BEGIN TO TAPER OFF.

SUNDAY...THINKING THAT MODELS MAY BE OVER DOING THE CHC OF PCPN SINCE
RIDGING WILL BEGIN TO BUILD ACROSS THE AREA. ANYHOW WILL KEEP LOW
POPS FOR THE MRNG/AFTN HOURS ONLY. RIDGING SHOULD BE STRONG ENOUGH BY
THE NIGHT TO REMOVE THE CHC OF PCPN.

MONDAY/TUESDAY...CONFIDENCE BEGINS TO DROP OFF BY THE BEGINNING OF
NEXT WEEK BUT FOR NOW...THINKING THAT UPPER RIDGING WILL CONTINUE
THE DRY CONDITIONS WITH VERY WARM TEMPS...HIGHS NEAR 90.

WEDNESDAY/THURSDAY...ANOTHER UPPER TROF/CDFNT WILL BEGIN TO AFFECT
THE CWA WITH MORE SHRA/TSRA. ATTM THE GFS HAS THE CDFNT MOVING THRU
THE CWA BY THURSDAY NIGHT.

FRIDAY...THE CDFNT IS PROGGED BY GFS TO BE WELL SOUTH OF THE TN
VALLEY WITH A LITTLE COOLER/DRIER AIR MASS.
