Weather Outlook

Date & Time: 6/5/2023 @ 9:50 AM MST

Forecaster: Henz, D.

Large scale blocking patterns affecting the western US have been a big weather story most of this spring and continue to play a large role in the day-to-day and week-to-week conditions we’re seeing here in the Desert Southwest. We’re coming out of a wet winter/spring that has also featured many extended periods of colder than normal periods thanks to cold air intrusions and passing disturbances. Looking at the big picture for this upcoming work week, a blocking ridge will remain entrenched across the central US with troughing and a slow moving disturbance entering the Desert Southwest. Coming full circle, this pattern will promote a general downtrend in temperatures after today as well as periods of breezy conditions. We won’t see any rain chances through the extended forecast, but it’s hard not to love seeing upper 90s in June.

For today plan on mostly sunny skies with some passing high clouds. We’ll also see hazier conditions due to local fires burning across eastern AZ and perhaps lofted dust later today. Afternoon temperatures will quickly warm into the 103˚F-105˚F range around the Valley. South winds will climb into the 7-15mph range with gusts around 20-30mph into afternoon/evening hours. Overnight lows will dip into the mid to low 70s around the urban corridor under clear skies and breezy conditions.

Temperatures begin trending down tomorrow despite plenty of sun in the forecast. Daytime highs will step back into the 96˚F-99˚F range around the Valley. South/southwest winds will be breezy again in the 7-15mph range with gusts around 20-30mph perhaps leading to some areas of localized blowing dust. Additional cooling is expected in the forecast for Wednesday and Thursday with highs in the mid to upper 90s across the lower deserts to go along with dry and breezy conditions.
