 Wouldn't be surprised if we see another heat advisory. We're still in the 90s on Wednesday, again on Thursday, and a one-day break with highs in the lower to middle 80s on Friday. We're back into the mid to upper 90s for the upcoming weekend. DC's mayor has extended the district's heat emergency through Thursday this week, which means DC's cooling centers and water spray parks are open for folks to find some relief. In Fairfax County, the public school system has canceled all outdoor activities for today.
