Warm Beginnings this Week, Colder & Possible Showers this Weekend Featured

Warm to start out this week, but much cooler and possible showers over the weekend.

Big Idea

  • Partly cloudy Monday and Tuesday
  • Warmer Wednesday - Friday
  • Cooler and maybe wet Saturday and Sunday
  •

Warm weather will become much cooler this weekend.

Forecast Summary:

Partly cloudy Monday - Tuesday, with light southerly to southeasterly breezes and a very slight possibility of light rain showers. Otherwise, the workweek should continue to be much warmer than normal, with highs in the upper 70s and lows in the mid to upper 40s. For the coming weekend into early next week, expect a pronounced cooling trend and very breezy weather, with highs dropping into the upper 50s and lows dropping into the 30s by Sunday. There is a chance of light rain showers on Saturday-Sunday, with another possible round of showers around next Monday.

High pressure will continue to dominate the weather pattern for the workweek. However, embedded within the upper-level ridge is a weak cutoff low that will circulate some moist southerly flow and create light breezes across Arizona through tomorrow. As a result, it will be marginally moist enough today or tomorrow for some isolated light rain showers. LIttle or no accumulation is expected.

Otherwise, it should remain much warmer than normal for the rest of the workweek, but changes are in store for the coming weekend. Two back-to-back troughs are expected to swing across Arizona this weekend. The timing of each trough and the potential for precipitation are still uncertain. It does appear that the weekend will become significantly cooler and very breezy, and that the second trough (expected around Monday) will be more likely to produce some measurable light rain or snow showers. Stay tuned to the local forecasts on the NWS website (see https://www.wrh.noaa.gov/forecast/wxtables/ and click on your location) for updated forecasts.
