Warm Mother's Day weekend ahead

Posted: Updated:

PHOENIX -- A strong ridge of high pressure means a warm Mother's Day weekend ahead. 

Look for plenty of sunshine and highs near 100 degrees today and tomorrow. Overnight lows will be in the 60s and low 70s. 

On Sunday, a low pressure system approaches from the northwest, bringing breezy conditions and cooler temperatures. Mother's Day afternoon temperatures shouldn't pass the mid 90s, and on Monday and Tuesday, the Valley will top out in the 80s. 

The Valley is under another Ozone Health Watch today.  Residents are urged to carpool or limit driving, refuel after dark and avoid gas-powered equipment.
