Climate Statistics for Mother's Day

Don't forget that this Sunday is Mother's Day, first recognized nationally in 1914 on the second Sunday in May.  It looks a chilly start, with some patchy frost around the area, and will likely register as a top 10 coldest morning. However, temperatures by afternoon should recover, with highs in the upper  50s to mid 60s, just a bit below normal readings for the day.  Listed below are extremes observed on Mother's Day over the period of record.
