After a brief period of unsettled weather over the weekend, dry and quiet conditions will be the main focus to start off the new work week. Looking at the big picture, an upper-level disturbance continues to shift east into the Great Plains while a new ridge of high pressure takes shape off the CA coast. This ridge will slowly strengthen and shift east over AZ by Wednesday. We’ll see near normal daily temperatures and cooler morning lows the next few days before warmer conditions into mid-week.

For today plan on mostly sunny skies across the region with perhaps some passing high clouds into this evening. Afternoon temperatures will only warm into the 98˚F-100˚F range around the Valley. Variable winds will hover in the 5-10mph range with no gusts of any consequence throughout the day. There will be no storm activity around the state today. Overnight lows will dip into the mid to low 70s around the urban corridor under clear skies and light winds.

Plan on another round of mostly sunny skies tomorrow with daytime highs climbing into the 100˚F-102˚F range around the Valley. Variable winds continue to remain in the 5-10mph range with limited gusts around 15mph. No storm activity is expected around the state. Sunny skies and dry conditions will continue into Wednesday with high remaining in the low 100s. Expect breezier conditions in the 7-14mph range and localized gusts around 20-25mph. Moving ahead, it’s possible we move into a more unsettled weather pattern to end the work week, but for now there’s still too much uncertainty in the guidance. We’ll have more details on this in the coming days.
