Area forecast discussion, Sep 5, 11:40 AM CDT, 2 hours 59 minutes before

Area Forecast Discussion
National Weather Service Shreveport LA
1140 AM CDT Tue Sep 5 2017

.AVIATION...
Cold front extends from across S AR from and KMEM and KHOT through
extreme SE OK and just S of the Red River across N TX this Tuesday
morning. This front forecast to move S into the NRN Gulf through
Wednesday with SCT TSTMS this Tuesday afternoon and evening.

Expect areal coverage and intensity to remain too sparse to produce
any MVFR ceilings or VSBY through this Tuesday evening through
sunset with clearing skies from N to S during Wednesday with
continued VFR conditions. /VIII/.

.PREV DISCUSSION... /issued 1133 AM CDT Tue Sep 5 2017/

DISCUSSION...
At 16z, the cold front was located just south of the Red River
between Oklahoma and Texas and extends east-northeast into Central
Arkansas. Scattered convection is still expected to develop across
much of the area this afternoon, especially Southern Arkansas and
Northern Louisiana. The atmosphere is not conducive to a
widespread severe weather threat. However, there is more than
enough instability to support a couple of isolated severe storms
this afternoon and into this evening. Damaging winds and large
hail will be the primary threats.

Otherwise, the remainder of the forecast for today looks on track.
Some minor updates were made to hourly temps to better follow the
latest trends.

PREV DISCUSSION... /issued 640 AM CDT Tue Sep 5 2017/

AVIATION...

cold front moves across the region. N winds will overtake the
region from n to s throughout today, and skies will clear in the
wake of the front by sunrise Wednesday. /12/
