Jim, the short answer is again no. Please re-read my email, as well as 
the excellent discussion written by Rich. There is no "negative" 
temperature correction that can be applied to nighttime drainage or 
radiational cooling effects that occur in valleys or areas that differ 
in terms of land usage and nearby topographic effects (such as rivers). 
If you are confident in your readings, then simply ignore the QC flags. 
We have an official NWS airport site here in NW MO that gets flagged 
nearly every night because the airport is situated along the bottom of a 
river valley. Is the data bad? No, the site fogs in regularly.

As for the cucumbers and tomatoes however, I will question why annual 
vegetables would still be in a pre-harvest state in a location where a 
hard freeze by this date is certainly not an anomoly :)

Best regards,
Evan
