ST.PAUL, Minn (KFGO AM) -- A number of public utilities across Minnesota continue asking home and business owners to remain diligent about running water to prevent freezing water lines.
You may have heard that frost actually drives deeper into the ground briefly as weather warms up.
But Assistant State Climatologist Pete Boulay says there is a lag time in how long it takes for a cold wave to reach the lowest point in the ground -- so it can start warming up outside but the cold waves are still penetrating far down underground.
Boulay says there is still quite a bit of frost underground.
He adds frost always drives deeper under pavement than beneath your yard.
