A Flood Watch will be in effect for South-Central Arizona from midnight through 9 PM MST this evening. Multiple rounds of showers and thunderstorms are likely to effect the area, with the potential for training of thunderstorms, meaning multiple may track over the same location, increasing the threat for flash flooding.
The Weather Prediction Center has issued a Moderate risk (3/4) for eastern portions of AZ today, while a Slight Risk remains for most of South-Central and Southwest AZ. Periods of heavy rainfall could lead to flash flooding of low water crossings and washes.
Abundant moisture, thick cloud cover, and a Pacific low pressure system moving over the region will lead to much cooler temperatures during the first half of the work week, especially across South-Central AZ. As the Pacific low pressure system departs, expect gradually warming temperatures through this weekend.
