Dangerous heat this weekend in the Valley

Posted: Updated:
PHOENIX (CBS5) -

Valley residents need to brace themselves for a heat wave by the end of this week.

Daytime highs will stay close to average today, with temperatures warming up to 106 degrees.  By Wednesday, however, temperatures will be around 108 degrees. 

The warm up will continue Thursday with 112 degrees and then the dangerous heat will set in, as a ridge of high pressure strengthens over the Valley.

On Friday highs could reach to 117 degrees and it will stay hot for Saturday, also.

The National Weather Service has issued an excessive heat watch for Friday, Saturday and Sunday for a large portion of Arizona.  Highs will be anywhere from 115 to 119 degrees.

The Valley will be close to record breaking high temperatures this weekend.

On Friday, June 28, the record high, based on about 118 years of data, is 118 degrees.  The Valley's forecast high is 117 degrees.

Saturday the record high is 117 degrees.  Temperatures out at Sky Harbor International Airport should reach 117 degrees, tying that record.

Temperatures will also stay warm overnight.  Most locations will stay in the upper 80s/low 90s this weekend, even late at night and early in the morning.

It is a good idea to avoid the direct sunlight during this hot week.  Also, check in on those who may be especially vulnerable in the heat, like children and the elderly.

Humidity levels will also increase early next week, as monsoon moisture starts to move into the state from the east.

Temperatures will drop a bit by Monday and Tuesday.
