How often it hails in Montgomery County

NOAA's Storm Prediction Center has logged 21 separate hail days here since 2010 -- 1.2 a year over 17 years of record. Those days carry 68 separate reports between them, better than three on a typical one. 7 of those 17 years produced none at all. One year dominates the record: 2011 alone produced 5 of the 21 days. The last five years have been quieter than the long run: 3 days since 2022, against 1.5 a year before that.

2 of the 21 days reached 2 inches or more -- 10%, or about one hail day in 10, the last on 2012-07-26. Those big days do not follow the county's usual calendar: most of them fall in May, not April. Golf-ball size is rarer still: 1.75 inches or more on 4 of the 21 days.
