PHOENIX — Our first 100 degree day of the year is here! The Valley taking to the triple digits just after 3 p.m. on Sunday.
On average, Phoenix's first 100-degree day happens around May 2nd.
High pressure stays put over the desert southwest for the next several days.
Triple digit heat will stay put for Monday in most Valley neighborhoods.
Heat risk will be minor to moderate the next few days. Make sure you are limiting your time outside, staying hydrated and using sunblock.
The above normal temperatures will stay put through Wednesday before a big cool down comes our way.
By the middle to end of next week, another weak storm system will move in. Winds will pick and temperatures will drop, bringing Valley highs down into the mid 80s again by Thursday.
As of right now we could see a few isolated showers and thunderstorms in parts of northern Arizona, mainly north of I-40 and along the Rim but the rest of the state is looking pretty dry.
Stay tuned for more updates as the system gets closer.
