Beaches, swimming pools and sprinklers will be getting a workout this weekend around the Buffalo Niagara region.
The first official weekend of summer will be the warmest one of the year so far, according to the National Weather Service forecast.
How high the mercury climbs this weekend will depend on location. Spots inland, or away from the lakes, could get into the 90s.
The heat wave is being generated by high pressure that will pull deep southerly air into the region as it drifts east.
Temperatures will get into the mid 80s Friday, but close to 90 degrees on Saturday and into the low 90s in parts on Sunday, forecasts show.
Humidity will also increase with the temperature, forecasters said.
Buffalo's temperature already made the 90 degree mark once this year - in a record-breaking Saturday back on May 28.
It was the earliest the thermometer hit 90 degrees in Buffalo since 1991.
