Thunderstorms are possible around Phoenix Thursday morning, and showers and thunderstorms are likely again today, with a Flood Watch covering the metro through 5 p.m. Localized flash flooding, hail and sudden wind gusts could make the morning commute and afternoon plans messy.

The National Weather Service Phoenix office describes uncertain storm coverage through the morning, with most activity possibly moving east of Phoenix by early afternoon. Rainfall could quickly reach 0.5 to 1 inch, with localized totals of 2 inches possible where storms train, so residents should monitor warnings from NWS Phoenix. The timing and flood-watch details update Hoodline's earlier outlook from Wednesday.

Storms Before The Sunshine

Thursday's high should reach about 82 degrees. Rain chances run about 70% for the day, with light easterly winds trending south to southwest and stronger, erratic gusts possible near storms.

Drivers should avoid flooded roads and washes, even if the water looks shallow. Stronger cells may produce large hail, damaging winds and an isolated tornado, while low-lying and flood-prone areas could see fast-moving runoff.

Friday Starts A Cooler, Drier Stretch

Storms should fade Thursday evening as dry air moves in. Friday is forecast to be sunny with a high near 78 as below-normal temperatures continue, followed by sunny Saturday and Sunday with highs near 78 Saturday and 80 Sunday and overnight lows around 60.

The cooler spell does not last forever: Monday climbs to about 83, Tuesday to 85 and Wednesday stays mostly sunny near 84. For Phoenix, the next several days look like a brief, cooler reset after Thursday's unsettled weather.
