PHOENIX -- A strong Pacific storm system could break a more than two-month dry streak in the Valley.

Sunday marked 65 days without any rainfall in Phoenix.

Dry conditions will persist across Arizona through Wednesday as weak high pressure remains over the region.

Temperatures will also stay a good 10 degrees warmer than normal for this time of the year. Expect occasional high clouds in the Valley with daytime highs in the low 80s and overnight lows in the low 50s.

By Thursday, we will see a pattern change across our state, starting with a weak front that brushes across northern Arizona. This front will kick up winds and drop temperatures.

We could see sustained winds of about 15 to 20 miles per hour in the Valley. Higher gusts of around 30 to 40 miles per hour are expected in the mountains.

This front is also expected to drop Valley temperatures back down to the upper 70s and could bring some light showers to the high country.

By Friday, a stronger system will move onshore along California. It is expected to track east into Arizona Saturday and Sunday.

As of now, it looks like the Valley could see up to a half inch of rain between Saturday afternoon and Sunday morning. We could also see high elevation snow.

Temperatures in the Valley are expected to drop into the low 70s both Saturday and Sunday. Winds will be breezy.

Stick with us throughout the week as we fine tune this forecast.
