PHOENIX -- The 3TV Forecasters are tracking what could be a big rain event and cool down starting Saturday afternoon and continuing into Sunday across Arizona.

As of the model update, it looks like the bulk of the rain is going to start sometime late Saturday night and during the day Sunday. This is all thanks to a tropical depression near Baja California that will be pumping moisture into the state, along with an increase in monsoon moisture coming out of the southeast. Dew points will be in the 60s to 70s, so it will feel pretty humid outside.

Along with the rain, temperatures are going to take a tumble. Afternoon highs for Saturday and Sunday should be in the low hundreds to the low 90s across the Valley. As of this article, forecasting models are indicating 1 to 2 inches of rain possible this weekend across the state, with locally higher amounts. This could bring some flooding problems.

Friday morning was pretty quiet across the Valley. Skies started mostly cloudy to partly cloudy with temperatures in the 80s. Dew points started in the upper 50s and low 60s.

By lunch in Phoenix, we're looking at a temperature of around 98 and an afternoon high of 105 under partly cloudy skies. Isolated storms are going to be possible once again during the afternoon and evening, with the main threats being gusty winds, lightning and dust in the Valley.

The best chances will be in the higher terrain. Tonight, look for a low of 85 in Phoenix under mostly cloudy skies.
