When someone tells you to keep a weather eye out or on something they mean watch it very carefully so you don't end up blindsided by change. That's always good advice when growing anything, but it's especially true about summer squash, cucumbers and other members of the Cucurbita pepo group. Once they start bearing fruit, it takes daily inspection to make sure you don't overlook some tender prize. And If you skip a few days of inspection you may find yourself looking at living baseball bats, because as tender as they are when they're young and small, they easily become tough skinned behemoths in a very short time.
These beauties will escape that fate. They'll make a nice side dish after they are battered and lightly fried.
