Dangerous Heat Continues - Rain Returns Late Week

Long Term Looks HOT

The "Dog Days of Summer"

Heat Advisories continue into Tuesday and likely beyond. Take frequent breaks if you must be outside. Also, don't forget the pets. If asphalt is hot enough to burn your feet it's hot enough to burn paws.

Dangerous heat indices will continue each day as we enter the new work week through about the Wednesday/Thursday time frame. By late week, rain chances will steadily climb to becoming likely areawide, especially Thursday and Friday, which will reduce the dangerous heat somewhat. Remember to take heat precautions: Take frequent breaks in the shadeor air conditions. Drink plenty of water, even if not thirsty. Bring pets indoors if possible, or provide shade and water. Check on the elderly, ill neighbors and family members.

After a brief break in the heat courtesy of some higher rain chances this weekend, the last week of July looks to remain hot.

Year after year we often hear about the dog days of summer. Here is a little background on where it originated. Going into the upcoming weekend and new workweek next week, heat will build across the region once again as rain chances drop slightly.
