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...

Showers and thunderstorms will be on the increase once again today
along and ahead of a strong cold front and deep upper level
disturbance. This activity will be more likely to move into our
region this afternoon before ending to our east later this
evening into the overnight hours. Some small hail cannot be ruled
out with this thunderstorm activity later today as the convection
will be accompanied with cold temperatures aloft making the hail a
possibility.

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

After a cool start to the day on Thursday, temperatures should
rebound quickly by afternoon and especially on Friday and through
the upcoming weekend. An upper level disturbance will approach our
region during the late weekend, early upcoming work week time
frame, bringing with it a chance of showers and thunderstorms
along and ahead of an associated cold front. It`s too early to
determine if severe thunderstorms will accompany the activity
Sunday into early next week but this possibility will continue to
be monitored.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency management personnel...amateur radio
operators...and storm spotters should not be needed through
tonight.
