Boise to near heat record Thursday, cool down for weekend

Boise temperatures will near record-breaking highs this week, then dip down to below normal by the weekend, according to the National Weather Service.

On Wednesday the high temperature is predicted to be around 79 degrees, well above the normal temperature of 63 degrees. But the area won’t likely see temperatures that match the record of 89 degrees set for this day in 1994, according to Les Colin, meteorologist with the National Weather Service.

Thursday, the high will swing up to a predicted 86 degrees and possibly could nudge out the record of 87 degrees, set in 1934. The normal high for that day is 64 degrees.

Wednesday and Thursday are expected to be mostly sunny and dry, Colin said.

After that, temperatures will begin to dip down. Friday is expected to be around the upper 70s and rain could move into the Treasure Valley that evening, sticking through Saturday. By Saturday the high temperature is expected to drop to the upper 60s. By Sunday, it could be in the low 60s. Come Monday, temperatures are predicted to be below normal — in the upper 50s.
