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...

Hot and humid conditions are expected today as temperatures climb
into the mid 90s to near 100 degrees. When combined with the high
humidity, heat indices will range from 105-110 degrees. Thus, a
Heat Advisory is in effect through 7 pm this evening. In addition
to the heat, isolated to widely scattered showers and
thunderstorms will be possible this afternoon into the evening
hours as a cool front moves through the region. An isolated strong
thunderstorm can not be ruled out, with locally gusty winds and
brief heavy rainfall possible.

.DAYS TWO THROUGH SEVEN...Monday through Saturday...

Drier air will move into the region in wake of the frontal
passage, reducing heat index readings below 100 degrees for the
upcoming work week. Rain chances to return to portions of the
region during the afternoon hours from Wednesday through the end
of the week as an upper low develops across the lower Mississippi
Valley. Severe weather is not expected at this time.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency management personnel...amateur radio
operators...and storm spotters is not anticipated at this time.
