Spokane cold snap expected to give up with more snow on Thursday night

A week of bitter cold temperatures should be improved on Thursday as a fresh layer of snow falls over the inner northwest.

A low of minus-2 was measured in Spokane International Airport on Tuesday morning-it is 29 degrees below the normal low, said Daniel Butler, a meteorologist for National Weather Service in Spokane. The high Tuesday was 18 degrees.

Cold weather advice is in effect through noon Wednesday, although temperatures are expected to remain in the individual digits overnight again through Thursday morning.

The arrival of a humid air mass over the region must warm temperatures in the upper 20s Thursday and bring milder overnight in the low 20s.

Two to 3 inches of snow are expected on Thursday night to Friday with more snow possible Saturday night through Monday. Snow can affect commuting Friday morning.

Heavier snow is expected over mountain passes and at higher heights.

Temperatures are expected to be heated closer to normal by Monday with heights over freezing.
