Synopsis:

 

We’ve finally reached the back end of an early week heat wave that has brought temperatures well into the 100s. Today will likely be the hottest day of the week before a welcomed cooling trend lasting into this weekend. The strong area of high pressure responsible for the above normal temperatures will flatten out and push east of the area into Thursday in response to a weather disturbance sagging south out of the Pacific Northwest. Daily highs are forecast to drop back to around 100˚F on Thursday before dipping into the low to mid 90s through Saturday. There will also be periods of breezy conditions beginning this afternoon lingering into Friday.

For today plan on mainly sunny skies across the region. Afternoon temperatures will quickly warm into the 105˚F-107˚F range around the Valley with higher terrain areas reaching the upper 90s to low 100s. To those of you spending extra time outdoors, make sure to take frequent breaks and bring plenty of water. Initially light and variable winds will gave way to breezier conditions (6-12mph range) this afternoon/evening with gusts around 20mph. Overnight low temperatures will dip into the mid 70s around the urban corridor under clear skies and breezy winds.

Our cooling trend starts tomorrow with daytime highs expected to drop back into the 98˚F-100˚F range around the Valley. Plan on mostly sunny skies around the Valley with some passing high clouds. South/southwest winds will be breezy in the 7-14mph range with frequent afternoon/evening gusts around 20-25mph. Further cooling is expected on Friday and Saturday with highs limited to the low to mid 90s. Quiet weather will persist through this period, with mainly sunny skies each day and dry conditions across the lower deserts. More details on the upcoming holiday weekend will be covered in tomorrow’s extended Outlook.
