Chasing weather history for the midway point of the work week.
Today’s forecast high of 102° is slated to match the record set on this date in 2009. This afternoon would mark the 4th 100° day of the year. Climatology says the 4th triple digit day of the calendar year usually doesn’t arrive until May 29th.
High pressure over the Baja peninsula begins to break down tomorrow, courtesy of an approaching storm system. This system stalls north of the state through early next week, setting the stage for a blustery stretch in southern Arizona.
Strongest winds arrive Friday and Saturday. Southwest wind gusts approach 30-40 MPH across the Sonoran Desert, kicking up blowing dust. These winds combine with low relative humidity and the ongoing drought to increase the wildfire danger. All of southern Arizona is under a Fire Weather Watch for Friday and Saturday.
Outdoor burning is not recommended during this timeframe.
Along with the winds comes a drop in temperatures. Highs for Mother’s Day Weekend run roughly 10° cooler than today. Expect low to mid 90s in the forecast between Saturday and Tuesday. Breezes linger into early next week.
