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

.DAY ONE...This Afternoon and Tonight...

Isolated to scattered showers and thunderstorms will occur
along and to the South of Interstate 20 during the afternoon
and expected to end in the early evening. Gusty winds of 25 to 30
MPH along with brief but locally heavy rainfall and deadly
lightning will be possible in and near the stronger thunderstorms.
Under the influence of a large ridge of high pressure aloft, the
daytime temperatures will warm into the middle to upper nineties.
The combination of the heat and relative humidity will produce
heat indices from around 100 to 105 degrees during the afternoon.
No hazardous weather is expected at this time.

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

An upper level ridge of high pressure will continue to build into
the region and dominate the weather pattern into the weekend.
Showers and thunderstorms will become more isolated with the best
chances South of Interstate 20. This ridge will also allow for
warmer daytime temperatures with high temperatures in the middle
to upper 90s. Heat indices will range from 100 to 105 degrees and
may rise higher to near the criteria for a heat advisory for
areas generally along and South of Interstate 20 across Louisiana
and East and Northeast Texas. This would be dependent on where
the dew points look to remain higher near the middle seventies during
the mid to late week. The upper ridge weakens going into the
weekend and a closed low pressure system aloft over the Southern
Atlantic Coast off South Carolina and Georgia, moves West
providing an increase in rain chances and a gradual cooling. No
hazardous weather is expected at this time.


Activation of emergency managers, spotter networks, and amateur
radio operators, should not be needed through tonight.
