Stormy at times for your Mothers Day Weekend with a frontal boundary dipping down into the Valley, which will provide a focus for storms. Disturbances will ride this front bringing potentially multiple rounds of rain and storms today into Sunday. Overall, the severe threat is low, but an isolated severe storm producing pockets of damaging winds and an isolated tornado can’t be ruled out, especially on Mothers Day. Otherwise, storms will generally produce heavy rain, frequent lightning, and gusty winds. Dry air will filter in on Monday, and hang around into Thursday. Weather looks gorgeous with sunny skies, highs around 80, and lows in the 50s. After that? Back to a more summer like pattern.
