Precipitation...

Several beneficial rainfall events occurred during the month of November.  At the beginning of the month, drought or abnormally dry conditions encompassed all of northern Alabama. However, by the end of the month, the relatively wet weather had reduced drought conditions and rainfall deficits in many areas.  A storm system during the first week brought around an inch of rainfall to many areas. On the 5th, conditions were cold enough at Huntsville to allow for some light sleet.  A couple of other low pressure systems brought more rainfall around the middle of the month, and then again during the fourth week.  However, it was the last system to affect the area on the last couple of days of November that brought the heaviest precipitation to the area.  Rainfall amounts for both days were over two inches at many locations, and were well over four inches at Huntsville.  In fact, a narrow swath of heavy rainfall from southern Lawrence County through portions of the Huntsville metro area totaled more than five inches in some spots.  By the time the month was over, precipitation totals were above normal at Muscle Shoals and Huntsville, and much of northern Alabama.  The 7.69 inches of rain that fell at Huntsville was the highest monthly precipitation total so far this year, and ranked as the 7th wettest November on record.  In addition, the 3.93 inches of rain that fell on the 30th broke a new record as the all-time wettest day in November history at Huntsville.
