...Weekend Winter Storm Has Impact on Central and Eastern Idaho...

.A winter storm coming in from the Pacific Ocean will spread snow
and wind into central Idaho late tonight, and eastern Idaho during
the morning on Saturday. While snow accumulations will be light,
the strong wind that will accompany the surface cold front will
cause heavy drifting snow and reduced visibility in blowing snow.
Persons planning travel through central and eastern Idaho should
be prepared for winter driving conditions. Check road conditions
and plan extra time to complete your travel. Carry clothing and
emergency items appropriate for the time of year.
