It should be noted that small gaps exist in the data and some years contain incomplete information.  Where gaps were considerably large, the break in the period of record was noted, as in the case for Guntersville.  Freezing temperature records were included in the statistics for years that only contained a complete or nearly complete dataset (no more than 10 missing days during the spring freeze season).
