Area Forecast Discussion

636 AM CDT Fri Jul 28 2017

.AVIATION...
An upper level disturbance across Eastern Oklahoma and Central
Arkansas was helping to produce some weak showers which may begin
approaching the TXK/ELD terminal airspace a little later this
morning. This precipitation would be falling out of a 12kft deck
so not sure if it`s even making it to the ground or not. This
activity should weaken in coverage and intensity through the mid
to late morning hours but the mid and high level cloud cover may
hang around through much of the day. Closer to the I-20 Corridor
terminal airspace, a mix of mid and high level cloud cover should
prevail today with a cu field developing by late morning into the
afternoon hours.

Have introduced VCTS in the evening and overnight hours for
terminals north of the I-20 Corridor and terminals along the
corridor as convection will be possible along and to the north of
a southward moving cold front. Left VCTS mention out of the
TYR/GGG terminals as coverage appears to be more widely scattered
through the overnight hours. Otherwise, expecting mostly VFR
conditions to prevail.

Southwest winds of 08/14kts will become variable just ahead of
the cold front late tonight with winds shifting around to a NNE
direction in the wake of the cold front during the day Sat.

.PREV DISCUSSION... /issued 534 AM CDT Fri Jul 28 2017/

DISCUSSION...
Another hot and humid day in store across the area as overnight
lows only falling into the upper 70s to around 80 for all but
extreme norther portions of cwa. A heat advisory has been reissued
for the aftn hours for LA/TX portions of the area, with heat index
values likely exceeding 100 degrees across AR/OK portions of area.
A backdoor cool front will enter sw AR durg the eve, where
scattered convection will develop near this boundary. Isold
convection possible by late aftn north of I-20. With pw`s possibly
reaching near 2.5 inches near the frontal boundary, locally heavy
rainfall may occur at a few locations. Increased northerly flow
aloft may also create cold pooling outflow boundaries and gusty
winds near storms, mainly closer to peak diurnal heating
associated with storm development across mainly sw AR portions of
the area. Convective redevelopment Saturday will be mainly south
of I-20 durg the morning hours, with slightly drier mid lvl air by
aftn. For the remainder of the wknd, welcomed reduction in
humidity as dewpoints fall well into the 60s across northern
portions. A return to more seasonal heat, humidity, and isold to
scattered convection possible by the middle of next week across
the area.
