Area Forecast Discussion
National Weather Service Shreveport LA
1113 AM CDT MON AUG 1 2016
.DISCUSSION...
Heat Advisory kicking in this afternoon for all of our northern
Louisiana parishes and the eastern half of our southwest Arkansas
counties as heat index values will exceed 105 degrees across these
areas later today. Slightly drier air in place farther north and
west will preclude our remaining CWA from meeting criteria so will
leave advisory as is for today. The current forecast is on track
and no changes are planned at this time. /19/

.PREV DISCUSSION... /issued 620 AM CDT MON AUG 1 2016/
AVIATION...
MVFR vsbys possible across LFK through 01/14Z. Otherwise, VFR
conditions to prevail across area terminals through the 12z
forecast period. South to southwest winds 5 to 10 knots today to
become light and variable after 02/06Z. /05/
PREV DISCUSSION... /issued 353 AM CDT MON AUG 1 2016/
DISCUSSION...
Upper ridge now becoming centered over the Sabine River valley as
the upper trof over the nrn Great Lakes region continues to push
ewd. The upper ridge will continue to increase its influence
across our region today through at least mid week, which will
allow for our temps to climb into the mid to upper 90s for most of
the region. Our far wrn areas are drier, and therefore may see
temps approaching the century mark today through mid week. Heat
index values reached 105-107 Sunday for several sites across srn
AR/nrn LA, and expecting that a few more sites will be added to
this occurrence. Therefore, have issued a Heat Advisory for these
areas from noon through 7 pm today. Expect that an extension/expansion
of this advisory may be needed as a our temps continue to inch
upwards through the work week. In addition to the heat, the
increase in influence of the upper ridge will likely keep our rain
chances on the decrease and mainly confined to the ern half of the
CWA.
Upper ridge will reinforce itself over TX, just west of where it
is now by mid week. This will cut its influence somewhat, and we
may see slightly cooler temps as a result. In addition, chances
for afternoon convection may increase, especially across our ern
areas all the way through the upcoming weekend.
