Rain Chances to End the Week

Excessive Rainfall Potential Saturday

Moisture out ahead of Hurricane Priscilla will help to promote some isolated shower and thunderstorm activity Wednesday afternoon, mainly across high terrain areas east of Phoenix. Quick heavy downpours and gusty outflow winds will be the main impacts. There is a very slight chance (10-15%) that a gusty outflow will move into the lower deserts.

Heading into the latter portion of the week, moisture associated with the approach of Hurricane Priscilla will continue to stream over the region allowing for a prolonged period of rain chances for most if not all of the Desert Southwest. Forecast accumulations range between 0.30-0.80" between Thursday morning and Friday night, with the high end of that range favoring higher terrain area.

With rainfall likely lasting into Saturday, the WPC has included eastern portions of our forecast area in a slight risk Excessive Rainfall Outlook. Potential accumulations range between 0.30"-0.75" for lower desert areas and 0.75"-1.00" for high terrain areas. High end accumulation forecasts (25th percentile) favor greater than 1.00" for some lower desert locales and greater than 1.75" for some higher terrain spots.
