| Light Rain began at 1720Z and lasted until 1830Z (11:20a-12:30p). Then after a lull and brief rain at 2030Z (2:30p), light rain began at 2130Z and became heavy by 2215Z. The rain began switching to snow at 23Z and at that time I removed the inner measuring tube from my gauge (3:30p-5p). At that time the gauge had .37” from the days rain. Snow began sticking to my board at 2330Z (5:30p) and was coming down heavy at times. More snow overnight to get to the total. Since the snow beginning at 23Z, the gauge collected .59”. |

| Wonderful moisture in this spring snow! The past 7 days have totaled 1.76" of water to measure! 29 degrees and 90% humidity, continuing to snow. The aspen branches are bent over but look to be fine. Streets did not need to be plowed since the daytime highs have been in the 50's and 60's leading up to this storm. But the grassy areas have a nice layer of snow. |

| Rain turning to snow about 5:00pm. The inner gauge was in place and received 0.25 inches of rain. The snow was stacked about 4.5 inches above top of the funnel and that melted value was 0.74 niches for a total reported value of 0.99 inches. The measured total snowpack value was less because the mixed layer of ice and frozen mud under the snow could not be recovered. |

| Reported gauge catch is highly uncertain due to snow "crowning" of the gauge on the fence rail. I simply pushed in snow that appeared to be on top of the gauge but not part of fence rail accumulation. It was hard to make that distinction.
24 hr snowfall is from the fence rail - snowpack is from the ground - an average of several measurements |

| Temperature range: 32-42 Rain and light snow before dawn. Wet snow during the mourning changing to off and on snow during the day. Heavier snow began at 4:45 pm and through the night, Snow stopped about 4:00 am. Some maple tree branches were down in my yard and along our road. Snow started again at 6:00 am. depth of snow on the snow board was 3.3 inches (9 inches in the field). The snow overflowed the rain gauge so reading is less than accurate. Driveways and roads were wet but not covered with snow. |

| Currently still snowing, although lightly and it’s 32°F. Yesterday, rain turned to snow very close to observation time, and continued to snow throughout the day and night. Trees are heavy with snow and the deciduous trees are bent dramatically with the weight of the snow, likely badly damaged with many broken limbs, just difficult to tell at this point since they’re completely covered with snow.. Seems to snow every year around Mother’s Day! |
