ORIGINAL POST: If forecasters with the National Weather Service in Boise are correct, the city will smash its record high temperature Monday. On July 1, 1924, a heat wave pushed the temperature in Boise to 104 degrees. Forecasters think Monday's high will hit 109. (At one point Monday morning, they were predicting 112.) The official NWS forecast location for Boise is for the airport. The high in the city's downtown is expected to reach 107.
Temperatures Monday morning hovered around 80 degrees in Boise. Because of the extremely high temperatures in the afternoon and the lack of significant cooling overnight, the Weather Service has issued a heat advisory for much of southwestern Idaho. It will stay in effect through at least Wednesday morning.
Boise set a record high for Sunday at 104 degrees. That topped the previous June 30 record of 103.
The heat is also affecting mountain regions where temperatures dipped to near freezing last week. Highs in the west central mountains and in the Wood River valley are expected in the mid 90s.
Forecasters predict some slight cooling in time for the 4th of July holiday on Thursday.
