Weather forecast: It’s here. WNY heat wave set to intensify this week. How hot will we get?

Weather Forecasts

Detailed forecast for Rochester, the Lakeshore & Finger Lakes

An extended heat wave is now underway across WNY, and it’s only going to get hotter from here. A Heat Advisory is in effect from Tuesday-Friday, and it’s not often you see these issued for that length of time so far in advance. This will make for one of the hottest workweeks across the area in years. Temperatures around 90 degrees this afternoon will slowly drop through the 80s this evening with dry conditions expected. We’ll fall into the upper 60s by early morning, the coolest overnight low we’ll likely experience all week. 

Minus a slight chance at a passing shower or thunderstorm, Tuesday will be headlined by more heat. We have highs climbing into the lower and middle 90s tomorrow, so we’ll be begging for raindrops for more reasons than one. Wednesday is more of the same. A slight chance for showers or storms exists into the afternoon and evening, but if you strike out you’ll be back into the lower 90s again. The hottest of this period should be Thursday and Friday as we contend with a one-two punch. Not only will air temperatures likely get into the middle 90s, increasing humidity levels could drive the heat index up to around 100 degrees. The higher humidity will also help keep our overnight lows running very warm with lower 70s expected. This combination will make it not only uncomfortable, but dangerous for those without A/C. 

While it may sound like common sense, it is worth reminding that you cannot leave anything alive in your vehicle during days like this. Double check to make sure you have your pets/children with you before leaving the vehicle. Every year, this becomes a news story as people simply forget, and it’s often a fatal decision. The hope is that this pattern breaks by the weekend, offering at least some relief from the heat and increasing rain chances.
