Moisture from the remnants of Tropical Storm Alvin will help increase humidity levels and eventually rain chances for cities such as Phoenix and Yuma, and potentially as far west as Las Vegas and Palm Springs, California.

Forecast models generally expect less than 0.25 inches of rainfall across southeast California, while parts of Arizona could see totals closer to half an inch.

Meanwhile, the NHC is now increasing the odds of tropical development for another potential disturbance off the western Mexico coast near where Alvin was born.

Speaking of poor air quality, forecasters are keeping a close eye on a significant plume of Saharan dust that is making its way off of Africa and through the Atlantic for the possibility that it could reach parts of the U.S. late next week.

If the current plume maintains its density, it could bring hazy skies and colorful sunrises to Florida and cut down on thunderstorm activity.
