8/9/2013 2:08 PM 0.07 M M M M Quite remarkable rain yesterday afternoon. Heavy rain began suddenly at 5:07 PM when I was at the old Soil Conservation Road exit from Goddard Space Flight Center onto MD 193. Heavy rain continued as I traveled east on 193, turned left onto Prospect Hill Road, and crossed Hillmeade Road onto Fletchertown Road (again going east). On Fletchertown Rd. the rain virtually stopped by 5:17, shortly before I reached Highbridge Road. I proceeded south on Highbridge, turned right on Old Chapel, and proceeded 1/2 mile west to my home (Station MD-PG-12). There was very little evidence of heavy rain along Highbridge or Old Chapel, and only 0.05" in my gauge at home. Today I measured 0.01" at 9:42 here at MD-PG-47. Yesterday's heavy rain essentially shot the gap between MD-PG-47 and MD-PG-12! Rain today began some time after 1:40 PM; +0.06" at 2:08.

The walls of the gauge extend 2.5 cm from the water level to the top of the gauge. It is therefore possible that an unknown amount of rainwater was splashed out of the gauge near the end of the storm if the rain was heavy at that time.

Based on loss recorded from rain collected on that date at a nearby station (MD-PG-12), this value should be increased by 0.06". However, a very light rain early this morning at both stations, amounting to 0.02" or so, should be subtracted from the total to provide the best estimate of rainfall at this station (MD-PG-47), i.e., 0.87".
