The National Weather Service issued a dense fog advisory for the Treasure Valley until noon Thursday, so drivers, pedestrians and cyclists had to be extra vigilant until the mist clears away.
The fog caused some trouble for air travelers at the Boise Airport, as at least two planes were not able to land Thursday morning. That means delays for people flying into Boise and delays for those people who were schedule to fly out on those same planes later Thursday.
The reason we had so much fog is all the precipitation over the past several days is hanging around the valley floor thanks to an inversion.
The high pressure near the ground is expected to break up by Thursday afternoon, as a low pressure system is expected to move through the area. That system should move some wind down to the ground and help move out moisture as the day gets warmer, according to National Weather Service reports.
Its expected to be partly sunny and cool in the Boise area for the next several days before more rain moves in by Sunday, according to reports.
The estimated high temperature for the Boise area Thursday is a cool 48 degrees which is 12 degrees under the average high of 60, according to the National Weather Service.
It should warm up some through the weekend, with estimated high temperatures of 52, 58, and 60 for the next three days.
