Area Forecast Discussion
National Weather Service Shreveport LA
1007 AM CDT Sat Jul 22 2017

.UPDATE...
15z observations running a few degrees below those we saw this
same time on Friday. Dewpoints are near to a degree or so higher
compared to 24hrs ago as well. Cu field is developing a little
earlier than Friday as well across our southern most zones and
latest meso analysis suggests this is where the higher PWATs are
located, in proximity to the upper level low across the S LA
coast. This is also where our highest pops are for today so for
that reason, not expecting to have to make any changes to the
ongoing forecast or the current Heat Advisory which was expanded
to include our entire region early this morning.

.PREV DISCUSSION... /issued 730 AM CDT Sat Jul 22 2017/

AVIATION...
For the ArkLaTex, a quiet start with our KSHV VAD wind profiler
showing SW flow from sfc up to 6-8kft then backing to NE 15-25KT
for flight levels per our balloon sounding. An Easterly wave is
stationed offshore of SE LA moving W and will likely enhance
p.m. convection for us, but how far inland today may depend on TS
outflow winds. VCTS for KSHV/KMLU/KLFK today, but once again
other terminals may require amendments for this eventuality.
