Area Forecast Discussion
National Weather Service Shreveport LA
1239 PM CDT Mon Jun 26 2017

.AVIATION...
Rather light showers were noted northeast of ktxk/north of keld
early this afternoon and thus will likely not affect either
terminal as the movement was to the east. Some isolated rather
light showers have popped up west of ktyr and struggled to
sustain itself thus computer models hinting at the activity
possibly affecting ktyr and kggg is likely overdone. Will pay
attention to radar trends and if a VCSH is warranted, an amendment
will occur. Relatively light east-southeast winds early this
afternoon will become light and variable /and at times calm/
overnight. Low level moisture gradually increasing across the
region will lead to the return of MVFR-IFR CIGS /particularly at
klfk/ and VFR-MVFR VIS /particularly at kggg and ktyr/. Have
denoted the above with a prevailing and TEMPO group respectively.
By mid to late morning on Tuesday any lingering low clouds/fog
will be scouring out whilst VFR SCT-OVC decks ensue.

DISCUSSION...
Water vapor imagery shows a trough of low pressure over the
eastern half of the US this morning, with a couple of weak
disturbances moving around this trough. One of these weak
disturbances is triggering some light showers over southwestern
Arkansas this morning. So far, only trace amounts have been
reported, but did update the forecast this morning to add these
showers to the forecast. Otherwise, the forecast looks on track
for today, with temperatures running a few degrees warmer today
than yesterday. Isolated diurnal showers and thunderstorms are
possible along our southern and western fringes associated with
another weak boundary. Palmer

.PREV DISCUSSION... /issued 305 AM CDT Mon Jun 26 2017/

DISCUSSION...
Tight upper ridge ovhd, as seen by isold showers wrapping around
center to the south and west of the cwa, and mid lvl cloud decks
movg eastward across se OK and central AR around topside of ridge.
This pattern will hold in current nw flow aloft until mid week
when upper flow becomes zonal across midsection of conus, allowing
gulf mstr to begin spreading nwd. Isold to possible sct
convection, mainly south of I-20 mid week, with increased
cyclogenesis over southern plains allowing for further
enhancement convection areawide for at least the first part of the
upcoming wknd. Also, convection becoming increasingly diurnally
driven as upper flow becmg very lgt and losing shear. Temps
gradually also becmg more seasonally warm as the week progresses
as atmosphere rebounds from backdoor drier airmass currently in
place.
