Increasing clouds, high of 69 today; rain coming this weekend

Posted: Updated:

PHOENIX – Rain is imminent as the storm system we’ve been watching all week makes its way to Arizona just in time for the weekend.

Clouds started moving in Friday morning ahead of the storm. The storm is already dumping rain on San Francisco and Sacramento, and forecasters are predicting that rain will turn into snow by Friday night when the colder air moves in, If it happens, it will be the first time in 35 years those areas have seen snow.

Here in the Phoenix Metro area, we’ll see quite a bit of cloud cover throughout the day Friday. It’s likely that the snow in the high country will start in the early morning hours Saturday.

Forecast models show rain moving into the Phoenix area at about 6 p.m. Rain is still possible during the day on Saturday, but it looks like most of the action will be Saturday night and into the early hours of Sunday morning.

Behind the rain, which should move out fairly quickly although lingering showers are possibly Sunday afternoon, is some very cold air.

It’s going to be partly sunny Friday with a high of 69 degrees. The overnight low will be about 48 under partly cloudy skies.

Saturday brings clouds, breezy conditions and a chance of showers. The high will be about 66. Rain is almost a sure bet overnight and into Sunday. The winds will also kick up a bit, which means there could be some areas of blowing dust.

It's going to be breezy, cloudy and cold on Sunday. With that cold air mass moving through on the heels of the rain, we’re looking at the high of just 53 degrees. That would be the lowest high ever reported on the Feb. 27.

The cold temperatures won’t last, though. We’ll be back up to 65 on Monday and then into the 70s as the week goes on.
