It's going to be sunny, so don't worry about anything but passing afternoon thunderstorms to spoil barbecues and picnics. But highs will likely near or surpass 90 degrees Friday through Monday, with uncomfortable humidity on what could be the hottest days of the year so far.
As of Tuesday, the National Weather Service was forecasting highs of 90 and 91 degrees Saturday and Sunday with relative humidity that would put dew points above 70 degrees. That means serious moisture in the air that will have many ready to turn on the air-conditioning and open up backyard pools.
AccuWeather.com is calling for highs of 90 degrees or higher Saturday, Sunday and Monday, with Sunday the hottest at 92 degrees.
With that sort of heat and humidity, afternoon thunderstorms are a possibility each day.
Considering that May's average temperature is already running 4.5 degrees warmer than normal, turning up the heat for the end of the month will only raise the average further. That would mean 16 consecutive months of warmer-than-average temperatures.
The heat won’t set any records -- 94, 95 and 97 degrees for Saturday, Sunday and Monday, respectively. It is well above the 78-degree highs normal for late May.
