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...This Afternoon and Tonight...

Dangerously hot temperatures with heat index values reaching or
exceeding 110 degrees are expected areawide this afternoon. An
Excessive Heat Warning is in effect as a result, and precautions
should be taken to avoid heat-related illnesses. As much as
possible, limit outdoor activities to the early morning or early
evening. Drink plenty of cool water, take frequent breaks in the
shade, and exercise caution while out in the sun for even short
periods of time. Wear lightweight, loose-fit, and light-colored
clothing. Remember to check on those most susceptible to heat-
related illness including the elderly, young children, and pets by
making sure adequate air conditioning is available.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday...

The Excessive Heat Warning has been extended through Saturday
Evening for the entire Four State Region. Very hot temperatures
in excess of 100 degrees, with heat index values near or above
110 degrees are expected to continue through at least Saturday and
may extend into Sunday as well. Heat related headlines may even
extend into early next week before a gradual decrease in
temperatures is expected by mid to late week as the upper level
ridge retrogrades westward away from our region. Chances for
thunderstorms will be increasing slightly during the mid to late
week timeframe as well, which may further aid in easing the
prolonged heat wave.

.SPOTTER INFORMATION STATEMENT...

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