Look for thunderstorms each afternoon.

Big Idea

  • Moisture will increase
  • July was a very wet month
  • Rainfall records were broken in several places
  • Expect scattered afternoon thunderstorms each day.

It could rain every afternoon this week!

 

Overview:

Following a mostly dry week, this week looks to become more active again as moisture once again surges north into our region.  This will bring a chance for thunderstorms each afternoon.

Forecast:

Moisture will increase today, with a good chance of thunderstorms from late afternoon and lasting into the evening. There may be some stronger storms this evening, with shower activity lingering overnight and into Tuesday morning. For the remainder of the week, expect scattered afternoon thunderstorms each day. Temperatures will be a little cooler due to increased cloud cover, with highs generally in the upper 80’s to lower 90’s.

 

Additional notes for the weather nuts:

July was a very wet month, with rainfall records broken in several areas. This was partly because the average July subtropical high pressure center at middle levels (500 mb or about 18,000 ft) of the atmosphere was located near the Four-Corners. Since air rotates clockwise around highs, this placed most of Arizona within moist east or northeast flow for much of the month. At other times of the year, high pressure generally brings settled weather. However, the movement of our summer monsoon thunderstorms is largely controlled by the location of the high. When the high moves to our south, dry westerly flow usually shuts down monsoon precipitation. However, when the high moves to our north as it did in July, moist easterly flow allows storms that form over the Mogollon Rim to propagate westward into Yavapai County.  Disturbances within this easterly flow can help to organize convection. This pattern will return for this coming week.

 

Have a great week!

 

Mark.
