A week of 100-degree-plus temperatures will bake the Rogue Valley before temperatures drop back into the 90s by Saturday.

A week of 100-degree-plus temperatures will bake the Rogue Valley before temperatures drop back into the 90s by Saturday.

The National Weather Service predicts the mercury will top out at 101 to 105 through Friday, before dipping down to a more normal 91 on Saturday.

Lows at night will only drop to the mid 60s, which will force residents to turn on fans and air conditioners in attempts to stay comfortable.

Smoky skies will continue through the week as well, aggravating those with bronchial conditions.

On Monday, the temperature gauge soared to 100 by 3:06 p.m., according to the weather service offices near the Medford airport.

The smoke will likely persist until at least next week, when air flows will shift to a more west to east direction from the current south to north movement.

"Right now there is not any strong flow at all," said Chuck Glaser,

Normally at this time of the year, the average high temperature should hit about 93. In another week, the average high normally drops to 90.

For the month, the only days that came close to the average high were Aug. 9 and 10 when the mercury rose to 91 degrees.

Overall for the month the average temperature, which takes account of the daytime high and night time low, has been 78.1, 2.7 degrees above normal.

The weather is a far cry from the cooler spring this year. Until Aug. 4, the valley had gone 709 days without hitting 100 — the second longest on record, after a 732-day streak that ended July 25, 1958. The high temperature on Aug. 4 was 105.
