Snowfall- picked up 1.3″ with the morning snow, with it mostly from the 8:30 squall line with the artic front. New depth on top the hard pack 4.0″, hard pack depth 5″-6″. Avg SD is 9″. Much higher than other locations. Partly due to almost no melt in the very warm day last week, and no settling in the fluff of blow off like elsewhere over the past day

Light snow predawn hours, with some better snows during the morning and a few nice pockets of snow, after noon, evening, and after dark. Falling Temps. A big temp difference overnight from Mchenry to Bittinger 2nw Valley again. Mchenry went to 36° overnight, Bittinger 2nw Valley held 20s. Snow, even mixed with rain and struggling to stick up until 6am Mchenry.. Not the case just east.

Snowfall-picked 6am boardsweep I had picked up .3″ at Bittinger 2nw Valley, through the day up until the 6pm sweep I recorded an additional 2.4″ for a evebt tally of 2.7″ with that pushing the season to date to 50.3″. Snow depth in the valley at 6pm, 7-8.5″.. (at 4 p.m I had 1.9″ on the day, a burst from 4pm to 6pm put down a quick 1/2″ of fluff)

Mainly clear beginning to end. Cold valley start. I did not have a logger on the Glades, but with reasonable certainty it likely fell under 0 last night. Colder east, milder west setup today, and a look

The forecast fail. A repeated, documented over and over and they are so stuck in their ways, I suppose it matters not that it fails, but they don’t budge from their airport grid procedure.
First last night, forecast min for Oakland 16°. 16 was only seen at some of the highest locations(like the airport) Mchenry, Oakland, areas where lots live,,well below 16°.. Today, they set up a temp map with very little variance across the county. The 3km Nam, was very good as always. Reality was, Savage Mt held 20s, not mid 30, I held low 30s not mid 30s, Mchenry ran upper 30s,,not mid 30s But using that grid,,blending it out, they fail to see the difference and that’s why in freezing rain events their forecast adjust as the event unfolds and is nowcast, not a forecast.. It’s ever changing. The airport grid SUCKS and it’s used and fails and has failed for years.
Periods of light snow through the morning, windy, minor accumulations. Breaks of sun as well through the afternoon.

Wild temps today- colder valleys, protected areas. Snow cover refrigeration effect. Strong winds afternoon, late day in Mchenry, just east, calm. Very mild through the day in Mchenry, just east cooler and sheltered valleys even cooler yet. The HRRR model did a fantastic job at hinting at this.. see videos below
6pm calm 32.9, snow didn’t even melt off trees any at Bittinger 2nw Valley today….while all afternoon and evening winds going strong at Mchenry.
