This presently ranges from 0 to 2.5 inches around my precipitation reporting location, my back yard, which is overall more sheltered than average for this part of town; partly shaded by trees on the south side, and sloping slightly northward. Areas that get little direct sun show negligible loss of snow during these short cold days.

9/10/2013 7:00 AM 3.26 2.0 1.18 M M Heavy precipitation as rain plus pea-size hail took place over about 15 minutes, around 3:30 p.m., tapering off to light rain, then off-and-on showers through the evening and night. Total precipitation recorded in gauge from the main storm event (measured about 2 hours later, about 5:30 pm) of rain + melted hail was 2.73 inches. An additional 0.53 inches of rain fell during the evening and night. All the hail probably was not collected in the rain gauge, as the funnel was in place and some hail probably bounced out; from some pails on the ground, the total rain+hail precip was probably at least 3 to 3.25 inches. The hail deposit remaining on the ground, 2 hours later, is reported as "snow" in my report; seemed to average about 2 inches depth on undisturbed grassy area, and a melted "core" of this hail layer contained 1.18 inches of water; so, total precip during the main storm appears to have been about 1.25-1.5 inches of water as hail, 1.5-1.75 inches as rain. Most garden plants destroyed by the hail and many leaves shredded off trees.
