The Rogue Valley will heat up this weekend as a wave of summer-like weather hits.
On the heels of a midweek low-pressure system that brought rain on Wednesday and Thursday, temperatures are expected to climb above 90 degrees on Saturday and Sunday.
"Springs are like that," said Chuck Glaser, data acquisition program manager at the National Weather Service's Medford office.
"It's a transition period."
Rapid temperature swings aren't uncommon at this time of year, he explained. Indeed, the coming warm spell is not unlike the one that sent temperatures soaring in mid-April.
Records were set April 20 and 21 in Medford as temperatures climbed above 90 degrees. That was pushed by a ridge of high pressure that built up across the region and delivered unseasonably hot, dry weather.
A cold front had dissipated by Thursday afternoon, bringing sunshine and blue skies. Now, high pressure is expected to build through the weekend.
Some clouds are expected early today, but will clear out by the afternoon. Today's temperature should hit near 80, Glaser said.
Things will warm up even more over the weekend, with Saturday's expected high in Medford nearing 90, while Sunday could reach up to 95.
The warm spell mirrors a heat wave that brought record temperatures to the Rogue Valley one year ago. The record temperature for May 15, set last year, is 98, while the records for May 16 and 17 are 100 and 102, respectively, also set last year.
Glaser said the normal daytime temperature for this time of year is 72 degrees, but those average numbers tend to rise steadily as May progresses. By the end of the month, the normal daytime temperature is 76.
The forecast for next week still is uncertain, but expect clear skies. Temperatures should start dropping Monday, with daytime highs in a comfortable mid-70s to mid-80s range through Thursday, Glaser said.
