PHOENIX -- The storm system headed our way is shaping up to be the wettest storm for metro Phoenix this year.

The latest forecast models are still showing us a solid 1 to 2 inches of rain across the Valley by early morning Saturday. Some areas of the Valley, especially northern and eastern portions, could see even more rain than that. Rain stays in the forecast through Sunday.

Still, the main band of moisture appears to be moving in for Friday, beginning in the early morning hours and continuing throughout the day.

So far this year, the biggest rainfall total at Phoenix Sky Harbor International Airport was on Jan. 26 and 27 when we got 1.34 inches of rain. The next closest is July 19-21 when we got .98 of an inch.

The same charts are showing us that areas along the Mogollon Rim could receive more than 3 to 4 inches of rain. As a result, portions of north-central Arizona are under Flash Flood Watches.

Eastern Arizona is under a Winter Storm Watch for the weekend.

The storm will also bring us much cooler temperatures. Highs through the weekend are only expected in the low 60s. We will see more sunshine on Sunday than Saturday, but both days continue with chances for rain.
