Partly cloudy skies and cooler weather today in the Temecula Valley is the result of a weakening low pressure system grazing the region. There is a slight chance of light showers in and around the mountains, but that should be it. Warming will begin again tomorrow, and afternoon temperatures are predicted to be in the 80's Monday through Wednesday. Offshore flow will help fuel the warmth Sunday and Monday; temperatures will peak on Tuesday. Cooling is anticipated later in the week.

Today's pollen level is rated "high-medium".
