11/10/2010 8:50 AM 0.29 T M M M This was our first snow of the season. It has been very warm. Well more than trace snowed, but ??? Ground was so warm it melted. Just a bit (maybe 0.2") on grass (small area), but whole rest of yard had no snow. TV had said we could get as much as 5" in some places near Denver, but I don't think we got that much.
11/11/2010 8:50 AM 0.06 0.3 M M M Since most of the snow was melted on the grass, I wonder if the snow depth was accurate on the board (on the grass), or if some melted.

I can't get my leaves from a cottonwood (bad for smothering plants) cleaned up because of all this light precipitation. It does nothing for the plants, but wet leaves cannot really be vacuumed up from the gardens (can't rake gardens).

11/17/2010 8:50 AM 0.17 T M M M The snow board was covered with ice. Maybe some snow had melted off earlier. It rained here in the afternoon of the 16th before it turned to slush and then snow, so I really don't know what was what.

The garden is suffering, so I thoroughly watered 2 weeks ago when it was warm. This takes 2 afternoons between 1 (has to be warm) and 4. Hand-watering the areas not covered by oscillating sprinklers is the worst. I have only gardens and trees, only a patch of grass. Winter watering really pays off in spring and summer survival, though. Gotta keep those root hairs alive, as well as the foliage.

7/14/2011 8:00 AM 0.77 0.0 M 0.0 M Hail yesterday about 6:20-6:30 p.m.. I was 1 mile away with quarter-sized hail (in Cherry Creek), but not home. When I got home, I saw torn leaves consistent with less or smaller hail or both. No hail on ground.
7/15/2011 8:00 AM 0.66 0.0 M 0.0 M 9th day in a row of rain, with frequent very intense rain cells and hail (I only had hail once, 2 days ago). Much flooding in vulnerable areas, with cars floating, even yesterday (don't they learn?!). 40 airplanes at DIA were damaged by hail yesterday. Flooding and mud/rocks slides in Boulder 4-mile canyon fire (2010) area has closed roads and forced evacuations. DIA readings of precipitation are half, at most, of what central Denver has been receiving.

6/19/2011 8:05 PM No hail pad. Recovering from surgery, so all observed out the window. Garden plants prevented estimation of distance (hail pooled on mulch, but was not 100% confluent where pooled). I am used to seeing hail from window before I measure it, so am confident about size. The larger ones were rare. 3/8" 1/4" Pea Size 1/4" Pea Size White Ice 3 2min minor leaf damage Continuous True After rain vertical
7/13/2011 6:18 PM I was in a restaurant in Cherry Creek, at 3rd & Detroit (Denver), about 1 mile SW of my usual location. Hail was oval and flattened--I listed larger diameter. A few had a clear center. The restaurant had a courtyard and I saw it bouncing on umbrellas, so angle is approximate (sheltered from wind). It lasted 12 min. 1" Quarter Size 7/8" Nickel Size 1/4" Pea Size Hard|White Ice 3min shredded leaves Continuous True Same time as rain Before smaller hail vertical
7/13/2011 6:30 PM I was 1 mile away when hail occurred at 6:18-6:30 p.m. (see separate report). When I got home an hour later, there was evidence of significantly less hail damage in my garden, and no hail left. Based on prior hail damage that I witnessed, I would guess pea-sized for not very long. NA NA NA 10min minor leaf damage True
