The weekend was a scorcher – at least by May standards.

Temperatures on Saturday and Sunday set new record highs for South Lake Tahoe and were expected to do so again today.

But a cooling trend is forecast to start Tuesday, with highs of 75 on Tuesday and 55 on Wednesday, and there’s even a chance of showers or thunderstorms this week.

On Saturday, South Lake Tahoe’s high temperature was 84, beating the previous record high for that date of 76 and tying the all-time recorded high (since 1968) for the month of May of 84 degrees.

Sunday’s high of 82 broke the record for that date of 77; and today’s high, forecast to reach 83, also is expected to beat the all-time high for that date of 76.

A hot spell in May is unusual, but it isn’t unheard of, said Kyle Mozley, meteorologist with the National Weather Service in Reno.

“It doesn’t happen often, but it can happen,” said Mozley, who noted 1954, 1973 and 2006 also had warm weather in May.

And it’s too soon to say if this weekend’s weather portends a sweltering summer, he said.

“That depends on what happens globally,” Mozley said, explaining that we are emerging from a La Niña weather pattern and heading into “neutral conditions.”

For those looking to cool off by jumping into the lake or a stream, the Weather Service has some words of warning. Despite the warm weekend, water temperatures in lakes and streams still are only in the upper 40s to mid-50s – low enough to easily result in hypothermia.

Also, those venturing into rivers and streams are urged to use caution, as flows may be swift because of spring snowmelt.
