As mentioned yesterday, a broad troughing pattern to our north is promoting a dry westerly flow that will persist through the end of the week. Starting Sunday, a shift to southwesterly flow will occur as a trough develops to the west. This pattern will strengthen as a closed low develops off the NW Pacific coast and slowly makes its way south along the CA coast and then inland. Expect a cooling trend and windy conditions starting Monday as the system approaches AZ. Currently, model guidance suggests that precipitation may be possible for the Valley sometime in a Wednesday to Friday window as the low passes over AZ. However, confidence is too low at this time to determine precipitation chances/timing but we’ll have more details for you in next week's outlook.
For today, expect plenty of sunshine with clear skies county-wide. Afternoon highs will be similar to yesterday reaching the 82°F-85°F range for the Valley. Mostly calm conditions in the 5-12 mph range will lead to increased breeziness with gusts up to 15 mph towards the evening hours. Overnight lows will dip into the low to mid-‘50s around the urban corridor under clear skies and slightly breezy winds up to 12 mph around the Valley.
For tomorrow, expect similar conditions to prevail with clear skies and warm temperatures. Afternoon highs in the 82°F - 85°F range for the Valley.
