Area forecast discussion, Jun 26, 4:24 PM CDT, 57 minutes before
Area Forecast Discussion
National Weather Service Shreveport LA
424 PM CDT Wed Jun 26 2019

.SHORT TERM.../Tonight through Thursday Night/

Scattered showers and thunderstorms were beginning to spread
nwd across East TX lakes but should diminish by later this eve.
High pressure will keep any convection very isold Thursday aftn
and eve and most likely limited to limited sea breeze in lgt
southerly flow. Aftn highs will rise to either side of 90 degrees
but mostly lower 90s on Thursday and fall to around 70 just above
dewpoints on Thursday night in lgt winds./07/.

.LONG TERM.../Friday through Wednesday/

Not much change from previous forecast in the extended.  An upper
ridge will continued to be centered over Eastern New Mexico and West
Texas by Friday and will gradually migrate northeastward into Kansas
and Nebraska during the weekend and through the early part of next
week. During the same period, a weak upper trough will slowly
retrograde westward across Arkansas and into Oklahoma, while a
stronger trough will move west along the Gulf coast and into South
Texas by Sunday morning. Diurnally-driven scattered showers and
thunderstorms will become fixture in the forecast during this
period. The highest chances for rain during any given day will
generally be south of Interstate 20 where deep layer moisture and
the influence of the sea breeze will be the greatest.

By next Tuesday, the trough over Texas will merge with a broader
trough axis in the westerlies that will be moving across the Plains.
This trough axis may act to further enhance our chances for
thunderstorms Tuesday and into Wednesday. Overall, the chance for
any organized severe weather appear low. However, downbursts will be
possible, especially from collapsing storms, which may produce
marginally severe wind gusts.

Moisture levels will remain relatively high. With the persistent
rain chances and associated cloud cover, daytime high temperatures
will generally hold steady in the upper 80s to lower 90s.
