PHOENIX -- Once again on Monday we saw triple-digit high temperatures around the Valley, with a record high of 103. That is the third straight day of record heat.

But now we're in for a bit of a break. Look for a cooling trend for the rest of the week and by Wednesday night and Thursday, we have a chance for a few showers around town. It will also be much cooler. The highs on Thursday will be around 80 degrees.

There were some thundershowers in parts of Arizona on Monday, including the South Rim of the Grand Canyon and the Mt. Graham area in southeastern Arizona.

There is a big ridge of high pressure in place over the state, but it's beginning to weaken and move off to the east. Over the next few days, we'll come under the influence of a trough of low pressure, that first will drag in some high clouds out of the sub-tropics and give us mostly cloudy skies on Wednesday. Then, that low pressure begins to make its move in on Thursday and as it does there will be a chance for scattered showers statewide. The best chances will be in western and northern Arizona but we will have a chance for rain around the valley.

That low-pressure will bring us cooler temperatures later in the week.

Overnight lows on Monday will be in the 60s around the Valley and 40s in the high-country. Highs on Tuesday will be in the 90s in the Phoenix area and the 60s up north.

We'll start seeing mostly cloudy skies on Tuesday night and into Wednesday.

Expect to see a line of showers start moving into western portions of the state early Thursday morning.
