.PREV DISCUSSION... /ISSUED 410 AM CDT Sat Jul 22 2017/

Increasing Louisiana area shower and thunderstorm coverage early
this morning in association with the northern Gulf of Mexico upper
level low will gradually work its way westward and into our area
over the weekend as the low continues heading westward. We`ll
generally carry increasing increasing rain chances today through
Sunday as both instability and moisture levels rise. The extra
cloud cover should cool high temperatures down a couple degrees
for a large part of the area. Models continue to indicate lowering
precipitable water values during much of the upcoming week as
mid/upper level high pressure attempts to build into our area, but
for now we`ll need to keep some low mainly daytime rain chances
in the forecast. The main weather story might end up being rising
heat indices as the upcoming week progresses. Area dew points stay
in the 70s while mid 90s to around 100 afternoon high
temperatures become more common, and this could have the potential
to bring heat indices closer to our 108 degree heat advisory
criteria. 42
