The Valley's second bout of snowfall slowed evening rush-hour traffic to a crawl and sparked many crashes Thursday, but conditions are expected to improve for the morning commute Friday, the National Weather Service reports.
It was fairly dry overnight Thursday, but parts of the Treasure Valley could get snow or freezing rain Friday morning, according to meteorologist Dave Groenert at the National Weather Service in Boise. Temperatures likely won’t get above freezing until Friday afternoon, when there will be a chance of rain. Interstate 84 and other major routes are expected to be mostly clear, but secondary roads could still present challenges for drivers.
The good news: The cold weather should ease up Saturday, with temperatures in the low-40s.
And wherever you're driving Friday morning, local law enforcement agencies urge caution and patience.
