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 Heat Advisory is in effect today for all of the Four State
Region. Temperatures will again climb into the mid and upper 90s
this afternoon across the area, and when combined with the
humidity, will result in heat indices ranging from 105 to 110
degrees. In addition, isolated to widely scattered showers and
thunderstorms will develop today over portions of East Texas and
North Louisiana, before diminishing by sunset.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday...

Very hot, humid, and mostly dry conditions will continue across
the region Friday through Sunday, as an upper level ridge of high
pressure begins to shift southeast into the area. This will result
in the hottest temperatures so far this summer, and when combined
with the humidity, will produce heat indices that will near or
exceed 105 degrees each day. However, a weak cool front will shift
south into the region late Sunday, which will focus an increase
in showers and thunderstorms over the area late Sunday through
Tuesday. The increased cloud cover and rain near and behind the
front will also contribute to slightly cooler temperatures Monday
through midweek.

.SPOTTER INFORMATION STATEMENT...

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