1157 AM CDT Tue Apr 25 2017

This Hazardous Weather Outlook is for portions of southwest
Arkansas, north central Louisiana, northwest Louisiana, southeast
Oklahoma, east Texas and northeast Texas.

.DAY ONE...This Afternoon and Tonight...

A surface tough across the Southern Plains will create a tightened
pressure gradient, which will lead to southerly wind speeds
increasing to between 15 to 20 mph with higher gusts. A Lake Wind
Advisory is now in effect from 10 am this morning through midnight
tonight.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday...

Scattered to numerous showers and thunderstorms are expected to
develop across the region Wednesday along and ahead of a cold
front and associated upper level disturbance. Moisture will
continue to deepen ahead of this front Wednesday, with strong
wind shear and instability expected to be in place as forcing
increases by the afternoon. This will result in the potential for
scattered strong to severe thunderstorms during the mid to late
afternoon on Wednesday, and possibly continue into the early
evening across mainly north central Louisiana portions of the
area. Large hail and damaging wind gusts will be the main threats
associated with the severe thunderstorms, however can not rule
out an isolated tornado.

Very warm, humid, and unstable conditions will return to
the region by Friday as this front lifts back north as a warm
front, with isolated to scattered showers and thunderstorms
possible along and north of this returning front Thursday night
and Friday. An isolated strong or severe thunderstorm can not be
ruled out Friday with this activity.

The approach of another upper level disturbance for the weekend
will result in the develop of a line of thunderstorms along a cold
front, that will move across the Four-State Region from west to
east Saturday night into Sunday morning. Once again, strong wind
shear and instability may lead to some of the thunderstorms
becoming strong to severe.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency management personnel...amateur radio
operators...and storm spotters will not be needed through tonight,
but may be required tomorrow afternoon.
