Today's Records and Climate Data

The Heat Wave shows no signs of giving way as flash drought conditions continue across the entire Four State Region. As a result, much of the region is under a Burn Ban at this time. The wildfire threat will continue.

A Heat Advisory remains in effect across our entire Four-State Region through at least Thursday, as afternoon heat indices will approach 110 degrees through much of this week. Heed all heat safety protocols if you plan to spend extended time outdoors!

Another day of triple digit temperatures as most all areas should see afternoon highs ranging from near 100 to near 106 degrees. Afternoon maximum heat indices will climb to near 105 to 109 degrees as well. Use precautions if outdoor activities are planned.

With oppressive heat expected to continue through much of this week, remember these heat safety tips.

Here are today's climate records for selected sites across the Four State region.
