Phoenix weather: More rain on the way

Posted: Updated:

PHOENIX -- Mother Nature is once again gracing the Valley with some much-needed rain, and more -- possibly quite a bit more -- is on the way.

According to 3TV meteorologist April Warnecke, the storms that are in the forecast Monday and Tuesday have the potential to drop a significant amount of rain, possibly on par with what we saw Friday.

Early morning storms rumbled through the Valley at about 4:30 a.m., dropping about 0.39 inch on north and central Phoenix. There was also a tiny bit of rain -- 0.03 inch -- at Sky Harbor International Airport.

Our rain total for the year is 3.31 inches, 3 of which came from the monsoon. While that's above average for the monsoon, we're still far behind where we should be for the year. The average amount of rainfall for this time of year is about 5.5 inches, which means we're about 2.20 inches short.

Most of Monday morning's storms seemed to be settling down relatively quickly, but there is quite a bit of moisture in the air.

The National weather Service issued a Flash Flood Watch for the northwestern part of the state starting at 9 a.m. and running though late Monday night. A watch means significant weather is possible, while a warning means it is happening or imminent.

"As an area of low pressure slowly approaches from the south today thunderstorm activity will increase," reads the watch. "These thunderstorms will have the potential to produce very heavy rain and flash flooding. The threat of flash flooding is high today and much of tonight."

That potential for flash flooding should serve as a warning to drivers to be aware of the possibility of flooded roadways and washes. Those are to be avoided at all costs. It only takes a few inches of water to disable a vehicle.

While the monsoon officially started on June 15, most of the weather action has been relatively recent. The season comes to a close on Sept. 30.

Storm chances remain in the forecast through Tuesday, diminishing by Wednesday. In addition to the rain chances, the weather pattern is also bringing us some cooler temperatures.

Plan on a high of just 93 degrees in Phoenix Monday, well below the seasonal average of 102. We'll warm up as the week goes on and should return to the low triple digits by the weekend.
