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

.DAY ONE...This afternoon and tonight.

Slightly milder conditions are expected today with afternoon high
temperatures forecast to climb into the middle-to-upper 90s across
most of the region. High humidity values will still allow for heat
index readings to range from 100-105 degrees during peak afternoon
heating.

Additionally, scattered to numerous thunderstorms will gradually
develop and expand with daytime heating as a weak frontal boundary
continues to linger just north of the region. Some storms may
produce brief heavy rainfall and gusty winds. This threat will
primarily exist this afternoon through early to mid evening before
storms gradually weaken with the loss of heating.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.

Isolated to scattered thunderstorms will remain possible on Tuesday.
Otherwise, a gradual warming and drying trend will resume thereafter
with heat advisories likely returning throughout much of this week
while thunderstorm chances increase again slightly by the middle of
the week. However, no organized threat of severe weather is
expected.

.SPOTTER INFORMATION STATEMENT...

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