PHOENIX -- The hottest temperatures of the year are moving into Arizona as a ridge of high pressure tracks across the state from the west. Some relief could come late week as monsoon moisture moves in.

Many Valley communities will see highs at 110 to 112 through at least Thursday.

Meanwhile, from the Kaibab Plateau east to the White Mountains, dry thunderstorms are possible each afternoon through Wednesday.

As the ridge of high pressure tracks into the Four Corners region Thursday, monsoon moisture will start to pump into Arizona from the southeast. Storms with some rain are expected to develop in the high country of northern, eastern and southeastern Arizona Thursday and Friday.

For the Valley, outflow boundaries from any thunderstorms that develop to the southeast could produce blowing dust Thursday afternoon and evening as well as Friday.

As moisture seeps into the Valley Friday and into the weekend, we may see some thunderstorms develop along with a small drop in temperatures. If there is not enough moisture in the atmosphere as expected, we’ll just see some dust for Independence Day and the streak of 110-degree temperatures continuing.

As of Monday, the National Weather Service of Phoenix reported it has been 120 days since Phoenix saw rain. This is the fifth longest dry spell on record.
