UPDATE: Expect multiple 100-plus-degree days next week, National Weather Service says

How many fans do you have at your house? How many wading pools? How many popsicles? That's probably not enough. Because next Wednesday, according to the National Weather Service, temperatures could get into the low 100s.

Some weather apps are listing a high of 107, and one person in The Oregonian/OregonLive's office even caught their app suggesting it might be 108. If Portland reaches 107, it will tie the all-time record for hottest day. 108 will break the record.

"107 has been hit three times," Will Ahue, a meteorologist with the National Weather Service, said Friday. "July 30, 1965, Aug. 8 and Aug. 10, 1981."

Ahue thinks that 107 is a little high of an estimate, at least for now. Currently the National Weather Service is predicting 100 or 101 degrees for Wednesday.

The rest of the week should be warm too.

"We are looking at a week of hot weather coming our way," Ahue said over the phone. "We have hot weather building into the area this weekend."

Tuesday's high is forecasted, as of now, at 97 degrees and Thursday's is 95.

By Friday, Ahue said, the temperatures should cool down into the upper 80s.

It's possible, even likely, that Wednesday's temperature will be record breaking, according to the National Weather Service. The current record for that day at the Portland Airport comes from 1986, when it temperatures reached 96 degrees.

There's another record that Portland won't break next week: longest streak of days without measurable precipitation.

"We are currently sitting at 42 days including today," Ahue said. "Right now, it's still out of the top 10."

The record? 71 days in 1967.
