BOISE -- A thin layer of snow on slick roads closed dozens of schools to close Thursday in the the Treasure Valley.
Notably, Kuna schools, Mountain Home schools, Horseshoe Bend Schools, and schools in BlaineCounty stayed open.
While the bad weather also caused several slide-offs and car accidents, they were reportedly far fewer than during Monday's winter storm.
Just about an inch of heavy, wet snow accumulated in Boise overnight Thursday. Temperatures hovered around 30 to 31 degrees.
KTVB meteorologist Larry Gebert says it wasn't the volume of snow that made travel dangerous, it was a layer of freezing rain underneath.
It was the worst case scenario because it was freezing rain first, Gebert said.
Traffic slowed in many places because of the slippery roads.
However, Interstate 84 and the Treasure Valley's main artery roads were largely cleared of snow throughout Thursday morning.
ITD spokesman Reed Hollingshead said state crews had been working throughout the night to prepare roads with de-icer, salt, and sand.
Roads in Boise and Meridian were snow packed and slippery during Thursday's commute. Hilly areas near Boise's foothills were reportedly very slick.
Both westbound lanes of I-84 westbound were blocked for two hours near Nampa at 4:25 a.m. after a semitrailer jack-knifed near the Garrity exit.
Two semitrailers slid-off at milepost 74 near Mountain Home, with one driving through the median and ending up on the opposite shoulder. No one was injured.
Another semitrailer reportedly slid-off at milepost 86 near Mountain Home.
Ada County dispatch reported less than six weather related accidents, and none with injuries.
Canyon County dispatch reported five accidents, one that included minor injuries.
Sergeant John Gonzalez of the Meridian PD reported several accidents, but no major problems.
