Mesonet Freeze Assessment

Here are the durations of temperature below certain growing thresholds
for each of the Mesonet stations during the freezes of the last four days.
The durations are listed in hours, rounded to the nearest tenth.

Some things that stick out in the data:
* With the exception of the far northwest and Antlers, all Mesonet
stations avoided extended time below 28 F.
* Only Boise City dipped below 32 F all four nights.
* The proression of the overnight frosts from NW to SE is interesting
