Everything looks good, the upcoming forecast should have no negative impact on the turf.
In this freeze thaw cycle we will be moving the flags on the North Course back and forth between the greens and approaches.When the ground freezes at night it's best to stay off the greens to avoid traffic footprinting.
From the 'Common Questions' page on this blog:
HOW SOON CAN THE NORTH GREENS OPEN IN THE SPRING?
A frost (frozen) layer in the greens causes water above that layer to sit, creating a "bathtub" effect. This condition leads to soft surfaces and foot-printing under traffic. As soon as the frost layer leaves and the water can release through the profile, creating a dry and firm surface, we will open the greens to traffic.
