Synopsis

Another quiet weather day is on tap for today as dry west/northwesterly flow dominates the mid and upper levels. Following suit, the warmest temperatures of the week are expected this afternoon as readings climb into the low 90s across southcentral AZ. Some unsettled weather, in the form of a weak passing disturbance, is expected on Friday into Saturday. Model guidance is still only calling for a modest cool down, breezy conditions, and an outside shot for some light showers to start the weekend before high pressure returns for Sunday.

 

For today plan on mostly sunny skies with a few passing high clouds into this evening. Afternoon highs will warm into the 87˚F-91˚F range around the Valley with higher terrain areas reaching the low to mid 80s. Winds will be breezy at times through this afternoon in the 6-13mph range with localized greater gusts around 20-25mph especially over the higher terrain north and east of the Valley. Overnight temperatures will dip into the low 60s to upper 50s around the Valley under mostly clear skies and light winds.

 

It will be a similar story for tomorrow with afternoon temperatures warming into the low 90s around the Valley. Increasing high clouds out ahead of an approaching disturbance will move in from the west into the afternoon/evening. Winds will be breezy at times especially over the higher terrain in the afternoon with localized gusts around 20mph. As highlighted above a weak disturbance will move through the state Friday into Saturday. The forecast calls for slightly cooler highs limited to the mid 80s. There will be slight chances for afternoon showers and even a high based dry t-storm or two with the focus over the higher terrain north and east of Phoenix. Measureable rainfall still isn’t look too good, but any high based storms could be capable of some light rain and gusty outflows.
