PHOENIX -- As advertised, your 3TV forecasters said we’d see our first 100-degree day on Sunday, and as of 1:15 p.m. Sunday afternoon, the National Weather Service confirmed that benchmark at Sky Harbor Airport.

According to the National Weather Service, the last time we saw 100-degree heat was on October 3, 2012, when the mercury rose to 106.

It looks like the triple digits will continue into the start of our next work week.

High pressure sitting over the northeastern Pacific continues to influence our weather pattern, keeping us dry and allowing daytime heating to push the mercury a good 10 to 15 degrees warmer than average.

For Monday in Phoenix, we’re forecasting a morning low of 70 with an afternoon high of 103. On Tuesday, we should reach a high of 100.

An area of low pressure diving down from Canada on Tuesday will swing a dry cool front in our direction starting Tuesday afternoon. Not only will this kick off a cooling trend for the Valley, but it will also kick up some breezy winds, especially in northeastern Arizona.

Highs in the Valley will dip into the mid 90s Wednesday, then continue to trickle into the low 90s for Thursday and Friday.
