So there is this cool website Lake Ice - Ice growth. Describes some ice growth formulas. I plugged in some numbers for the upcoming cold front on the front range. If a lake already has an existing cap, there should be around 5-7 inches of new ice growth by Tuesday of next week! If there is not an existing cap the ice will be much less thick. Crazy... Colorado is crazy. These numbers are only estimates, so I will BRING A SPUD BAR to be sure, but I expect there may be some new opportunities on the front range next week.
