We'll start with clear skies for our Saturday, but clouds will increase throughout the day:
Highs will struggle to reach the low 60s, and rain will arrive after dark; we'll see lows in the mid 40s overnight as the rain continues. Mother's Day will be cool with showers and temps only getting into the mid 50s. More rain will be around Monday and it'll be even cooler with highs around 50. There could be another round of passing showers Tuesday as temps only reach the low 50s once again; by Wednesday morning, most of the Valley will have gotten between .75" and 1" of rain:
Wednesday looks a bit milder with highs in the mid 60s and a passing shower possible. Thursday will be mostly cloudy with highs in the mid 60s. Partly sunny Friday with highs near 70.
