Sunday will be one last warm and largely rain-free day before shower chances arrive in the evening. Temperatures Sunday start in the mid-50s – 10°+ above normal for this point in the year – and head to the mid-70s as warmer and more moist air continues to surge into the area ahead of a storm system approaching from the west. Skies will remain mostly cloudy, though a few breaks in the clouds will still be possible especially in the morning.
