This Hazardous Weather Outlook is for portions of Southwest and
South Central Arkansas, Northwest and North Central Louisiana,
Southeast Oklahoma, and East and Northeast Texas.

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

A heat advisory will remain in effect until 7 PM CDT for the Four
State Region due to the combination of the hot temperatures and
relative humidity producing maximum heat indices of 105 to 108
degrees. Precautions should be taken to prevent heat
related injuries if out and about during the day. Scattered
showers and thunderstorms over the area will be capable of
producing gusty winds to 25 to 30 MPH, deadly lightning, brief but
heavy rain. An isolated storm may produce damaging winds as
storms develop on outflow boundaries from previous storms.

.DAYS TWO THROUGH SEVEN...Sunday through Friday...

An upper level ridge of high pressure will be weakening during
the late weekend with a gradual increase in rain chances with more
cloud cover possible. For the later half of the weekend daytime
high temperatures will continue to cool with higher rain chances
and additional cloud cover as an upper level low shifts across the
Louisiana and Upper Texas coastal sections. A possible wet
pattern will linger into the first half of the work week as the
upper low over Texas and another upper disturbance rounds the
base of an upper trough from the Great Lakes Region into the lower
Mississippi Valley. Rain chances will start to taper off as the
reformed and amplified upper ridge across the Rockies starts to
expand back across the Plains and Four State Region. For the
last half of the work week the daytime high temperatures will
climb back into the middle to upper nineties, with isolated
readings possibly reaching the century mark. This will return
the possibility of heat advisories for the late week.

.SPOTTER INFORMATION STATEMENT...

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