VALLEYWIDE -- Mother Nature reappeared with a vengeance Tuesday night, hitting virtually every part of the Phoenix metro area with rain and wind.

The storms also brought a lightning show accompanied by thunder. Lightning is actually being blamed for two overnight house fires.

Rainfall totals varied greatly throughout the Valley.

  • Apache Junction - 0.24 inch
  • Downtown Phoenix and Gilbert - 0.31 inch
  • Anthem - 0.35 inch
  • Queen Creek - 0.55 inch
  • Tempe and Mesa - 0.63 inch
  • Peoria - 0.91 inch
  • Surprise - 0.98 inch
  • Glendale - 1.02 inches
  • Goodyear - 1.06 inches
  • Chandler 1.18 inches

Some scattered flooding was reported on area roadways but traffic generally was moving well, even along eastbound Interstate 10 at 79th Avenue where a sinkhole dumped mud onto the freeway. That mud blocked the right exit-only lane, said 3TV Traffic Reporter Gina Maravilla.

The rain has also brought cooler temperatures, with highs not expected to top 100 degrees.

3TV Meteorologist April Warnecke says we could see more of the same as the storm chances are staying in the forecast for at least the next couple of days.

Rain is possible throughout the day Wednesday with chances increasing in the evening and overnight hours.

A moist and unstable air mass is responsible for this weather pattern and some of the individual storms it's spawning could be slow moving, which means heavy rain and flooding are possible.

Strong thunderstorms are expected in northwestern Arizona as the day progresses. The weather service has issued a flash flood watch for Coconino and Yavapai counties through late Wednesday night.

By Friday, storm chances should diminish significantly and the mercury should be back on the rise.

This is about par for the weather course for this time of year. August traditionally is our most active month in the monsoon. According to dates set by the National Weather Service, the monsoon ends on Sept. 30.
