High of 110 on Tuesday and excessive heat watch later in the week

Posted: Updated:

PHOENIX -- It's shaping up to be a hot and sticky week.

Plan on a high of 108 degrees under partly cloudy skies today. As a high pressure ridge moves in, those temperatures are going to go up.

 

Tonight's low will run between 78 and 88.s

Tomorrow will be 109 and the mercury just continues to go up from there. We should be right around 113 by the end of the week. We could see a heat warning on Thursday and Friday, especially since the overnight lows will be hovering right around 90.

We're also looking at a chance of thunderstorms in the forecast starting Thursday and lasting at least through the weekend.
