Highs will top out in the mid 90s across the Valley today, putting us a few degrees below normal for this time of year.
Breezes will die down and that will make our air more stagnant. As the sun beats down, ozone levels will be on the rise in the afternoon hours. The Valley is under an Ozone Health Watch today and it could be extended into Thursday and Friday, too. So, limit your time outside if you have asthma or COPD and try to carpool or use public transportation to help prevent our air quality from getting even worse.
Temperatures will climb as we head toward Memorial Day weekend.
It looks like we'll stay just shy of the triple-digit mark on Thursday, but we'll be back up to 100 degrees on Friday.
Then, we've got another cold front to track. Right now, it looks like it will move in on Saturday, picking up our breezes and dropping temperatures into the mid 90s Saturday and Sunday.
We'll start another warm-up next week, putting Valley temperatures near 100 on Memorial Day and in the low 100s by Tuesday.
