Area Forecast Discussion
National Weather Service Shreveport LA
215 PM CDT Fri May 26 2017

.DISCUSSION...
Expect one more day of quiet weather during Saturday absent a
triggering mechanism for showers and TSTMS. By Saturday evening, a
weak shortwave trough approaches and combined with the approach of a
cold front will develop convection for Sunday and Monday. The airmass
ahead of the front will be unstable with CAPES ranging 3000 to 4000
J/kg and thus can expect some severe weather as well with the passage
of the cold front.

During next week for the remainder of this May and the first few
days of June, a late season long wave trough develops over the desert
SW. This long wave trough will eject several distubances eastward
across the southern plain states and SE US throughout much of next
week with unsettled weather as well. /VIII/.

.PREV DISCUSSION... /issued 115 PM CDT Fri May 26 2017/

AVIATION...
For the 26/18Z TAF period, Cigs have finally lifted to low VFR
status this afternoon at almost all sites with strong southerly
winds around 15 kts and gusts up to 25-30 kts. BKN-OVC cu field
will continue to linger through this afternoon before cigs lower
again this evening and through the overnight hours, becoming MVFR
and possibly IFR closer to daybreak Saturday. Expect cigs to come
in earlier and linger even longer than we saw this morning so do
see MVFR conditions lasting through the end of the TAF period as
southerly winds begin to increase once again around or after 15Z
Saturday morning.

PREV DISCUSSION... /issued 957 AM CDT Fri May 26 2017/

DISCUSSION...
Expect a warm and breezy start to the holiday weekend. Currently, a
surface low continues to slowly deepen across SW OK and NW TX. Across
the ArkLaTex region, expect increasing SRLY winds throughout this
Friday as warm air advection continues as well. This will initiate
SCT showers and TSTMS for late this weekend and during Monday as
well. /VIII/.
