Cloudy tonight; rain likely Wednesday with a high of 65

PHOENIX -- A winter storm is coming our way, which means everything is about to change weather wise.

A steady stream of moisture is moving in from Southern California. While rain is possible this evening and tonight -- chances will increase during the overnight hours -- it is likely tomorrow.

The National Weather Service in Phoenix has issued a flash flood watch for portions of Arizona and extreme southeast California. The watch includes the lower Colorado River Valley, northwest Maricopa County, southwest deserts and the Yuma and Martinez Lake areas.

We will see a temperature drop with this storm, but not a huge one. The storm is wet, but not terribly cold. That means snow levels will be relatively high.

In the lower elevations, there is the possibility that washes, creeks and drainage areas could flood. Low desert areas could get as much as an inch of rain, with up to an inch and a half possible in the higher areas near Wenden and Wickenburg.

Plan on a high of 68 degrees today, 67 tomorrow and 63 on Thursday.

The front should clear out by Friday. We're looking at a clear Christmas Eve and Christmas Day.
