Cool Morning, Sunny and Warm Afternoon Across the Riverbend

Overnight, the low settles at 63 degrees and feels like 61. Winds ease to about 7 mph from the south-southeast, and the rain chance edges up to 4%.

On the allergy index, ragweed rates high and is the main concern. Grass, tree pollen and mold all rate low. Air quality is moderate, with particle pollution the primary pollutant.
