Update
Updated for 18z aviation discussion

Aviation
18z TAF discussion:
vfr conditions will prevail through the period. Dry weather is
expected across the area, with the exception possibly being at
kpib khbg. Here there could be a shower or storm this afternoon
but confidence in affecting the TAF site is not high. Southerly
winds will occur today around 5kts or less. Calm winds will occur
overnight at most locations. No significant aviation concerns are
expected. 28

Discussion
Similar conditions will occur today as the ridge remains in place
across the region. Pw values on the 12z kjan sounding is a little
higher this morning than yesterday but still relatively dry for
mid august(1.21 inches). This all will help keep showers and
storms suppressed today, with some potential in the far southern
part of the forecast area later this afternoon. It will be in this
region where better low level moisture and flow will occur this
afternoon. Temperatures today will once again be warm with highs
in the mid to some upper 90s. Thankfully, with enough drier air
remaining in place, this will keep heat indices mostly in check
for most eastern locations. Locations in the west will see heat
indices reaching 100 to 105 degrees this afternoon. 28
prior discussion below:
today through tonight:
the subtropical ridge will maintain relatively dry deep layer air
over much of the arklamiss today with precipitable water values
less than 1.5 inches at most locations helping to limit the
potential for deep convection. An exception will be over northeast
la into far southern ms where southerly low level flow will begin
to increase this afternoon, resulting in greater
moisture instability and the potential for isolated showers. In
addition, the southerly flow will raise boundary layer rh, and
this will cause heat stress to creep back up with a few values
reaching the 100-105 range. Any showers should dissipate quickly
by early this evening and quiet weather is expected to follow for
the overnight. Ec
Sunday through Friday:
the forecast through the end of this week remains on track from the
last few cycles. For the new week ahead, the synoptic pattern will
feature a building upper-level ridge over the western central conus
and weak troughing over the east coast. Better moisture returns back
into our region as the old frontal boundary washes out, with pwat
values mostly between 1.5 to 2.0 inches throughout the week -
especially in southern parts of our area closer to the gulf coast.

Flow around a weak disturbance over the eastern gulf of mexico early
in the week may actually keep drier air in place just a little
longer in northern parts of the arklamiss. By the end of the week,
more vigorous shortwave moving across the northern tier of the u.S.

Should push another front southward toward the deep south, but
confidence on seeing it push too far into our forecast area is low
at this time. Therefore, the chance for scattered summertime air
mass showers and thunderstorms is expected areawide each afternoon
through Friday.

With increased humidity and the upper-level ridge in place just to
our west, it still looks likely for especially northeast louisiana,
far southeast arkansas, and western portions of mississippi to see
peak heat index values around 105 degrees Sunday through Wednesday.

Therefore will keep the limited threat area for heat stress as is in
the hazardous weather outlook text and graphics. A heat advisory may
be needed through the delta region at some point over the next few
days, but increasing chances for showers and storms may limit
heating potential. Nf
