Synopsis:

 

The area of high pressure that brought our early week heat wave has flattened out and is moving east of the region today in response to a large trough moving into the Western US. This change in the upper-level pattern will bring a modest cool down to the region along with periods of breezy conditions. Daily highs will retreat to the upper 90s today before falling back into the low to mid 90s for Friday and Saturday. Looking ahead, high pressure is forecast to redevelop over the region Sunday into Memorial Day meaning a likely return to triple digit heat. It’s also worth noting that longer range guidance shows another possible cool down and even some shower activity in the cards by mid-next week.

For today plan on mostly sunny skies with some passing high clouds. Increased breezes this afternoon may lead to hazier conditions due to suspended dust. Daytime highs will step back into the 98˚F-100˚F range around the Valley with higher terrain areas reaching the low to mid 90s. West/southwest winds will be breezy in the 7-14mph range with afternoon/evening gusts as high as 20-30mph. Overnight low temperatures will dip into the low 70s around the urban corridor under clear skies and breezy winds.

Fully sunny skies will return tomorrow along with another drop in temperatures. Afternoon highs will fall back into the 92˚F-94˚F range around the Valley. West/southwest winds will be breezy again in the 7-14mph range with localized afternoon gusts around 20mph. Pleasant weather is expected through the first part of the Memorial weekend with highs limited to the mid 90s on Saturday to go along with clear skies and light winds. High pressure will redevelop over the region for Sunday and Monday with high temperatures returning to the low 100s.
