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

A Heat Advisory is in effect today. Temperatures this afternoon
are expected to climb into the upper 90s to near 100 degrees
across the Four State Region, and when combined with the humidity,
will result in heat indices climbing to between 105 and 110 degrees.

time outdoors, and spend time in air conditioned facilities.
In addition, there will be a chance of afternoon and early evening

the eastern half of the Four State Region. Precipitation coverage
may pick up by late in the work week into the weekend due to a
disturbance moving our way from the north and west.

stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

To reduce risk during outdoor work, the occupational safety and
health administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
