We're back to triple digits and sunny skies next week

Posted: Updated:
PHOENIX (3TV/CBS 5) -

Sunny skies and triple-digit temperatures return to the Valley with low-grade monsoon storms for the high country Sunday.

A drier air mass from the southeast is streaming into Arizona over the next couple of days. This is scouring out storm chances across the Valley and allowing only isolated to scattered weak storms develop across the high country with daytime heating during the afternoon for the next several days.

By Wednesday, an area of low pressure begins to track into Arizona from the west. This will increase storm chances for the mountains, but usher in a drier and cooler air mass for the end of the week. The Valley will remain void of any storms.

Models hint at some tropical moisture returning to Arizona next weekend.

In Metro Phoenix, look for a high of 104 Sunday afternoon with dew points dropping to the 50s. By Monday, highs heat up to about 107 and remain at or slightly above 105 through Wednesday. By Thursday, highs will dip to or slightly below 100 degrees. Morning lows will be in the 70s by Wednesday.

As for Hurricane Irma, as of their 5 a.m. update (Arizona time), it is a Category 4 storm with winds sustained at 130 mph and moving over the Florida Keys.

On the forecast track, Irma is expected to move near or over the west coast of the Florida peninsula later today, then inland over northern Florida and southwestern Georgia Monday afternoon.

Storm surge could be as high as 10 feet across south Florida with rainfall totals of 10 to 15 inches through Tuesday.

    We know the monsoon brings thunderstorms and rain to the valley during the summer, but it isn't our only rainy season. Phoenix and Arizona have two distinct rainy seasons.To get rain in the valley during the fall and winter months, we mainly look to the northwest. All summer long a large area of high pressure over the Pacific Ocean blocks storms and sends them north.
