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

.DAY ONE...Today and Tonight...

A potent upper level disturbance will move across the Four-State
Region this afternoon through this evening. This disturbance will
increase instability across the region, leading to the development
of a line of thunderstorms along a cold front. Some of the
thunderstorms will be capable of becoming strong to severe with
large hail, damaging wind gusts and isolated tornadoes being the
main threats. In addition, breezy conditions will occur along the
cold front, with northwest wind speeds increasing into the 15 to
25 mph range sustained, with gusts nearing 40 mph or higher this
afternoon through this evening. A Lake Wind Advisory is therefore
in effect from 9 AM this morning through 9 pm this evening.
Precipitation will be exiting the region around midnight tonight.


.DAYS TWO THROUGH SEVEN...Thursday through Tuesday...

A 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 development 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 be required early this
afternoon through this evening.
