Extremely light rain showers throughout the AM on the 3rd, with a brief mixture of wet snow mixed with the rain at about 10:45 AM. In the early PM, rain showers transitioned to light, scattered snow flurries. Heavier snow flurries were noted at 11:00 PM on the 3rd, accompanied by heavy winds. A light dusting of snow on grassy areas at time of observation. The 0.2-inches of new snow was measured on top of a car that was parked in the driveway overnight.

Light, wind-driven snow flurries in the AM on the 4th resulted in the accumulation of about 0.1 inches of new snow by about 10:30 AM, but all had disappeared by nightfall. For the first time this fall/winter, rime ice was visible along the shallow edges of Crescent Lake.
12/6/2009 7:00 AM T T T 0.0 0.00 Temperature and relative humidity at 7:00 AM: 18 degrees F. and 67 percent; dew point temperature: 6 degrees F. A brief, light snow flurry beginning about 8:30 AM on the 5th produced a light dusting but no measurable accumulation. The surface of Crescent Lake was at least 75 percent ice-covered this morning.

Light snowfall began sometime in the predawn hours on the 7th, with a few flakes of snow evident as early as 5:00 AM. For the first time this winter, Crescent Lake is 100 percent ice- and snow-covered.
12/8/2009 7:00 AM 0.01 0.4 0.01 T T Temperature and relative humidity at 7:00 AM: 25 degrees F. and 76 percent; dew point temperature: 16 degrees F. Light snowfall produced an accumulation of 0.4 inches by about 10:30 AM on the 7th, which then proceeded to melt by late afternoon. Extremely light flurries in mid-afternoon on the 7th yielded very find snow pellets but no additional accumulation. A few scattered flakes of snow were noted at the time of observation this morning.
12/9/2009 7:00 AM 0.65 1.3 0.24 0.5 0.10 Temperature at 7:00 AM: 34 degrees F. This station experienced the proverbial "wintry mix" over the past 24-hours. Of the 0.65-inches of precipitation recorded, 0.21-inches was in the form of rain and 0.24-inches in the form of melted snow or sleet. Of the 1.3-inches of new snowfall, 0.3 inches occurred between 9:00 AM and Noon on the 8th, followed by warming temperatures and extensive melting. Sleet that started falling about 5:30 PM on the 8th had changed over to snow by 6:30 PM. Total snowfall by 10:00 PM (by which time it had stopped snowing) was 1.0 inches. The 0.21-inches of rain fell sometime after 10:00 PM on the 8th (it was raining moderately hard at 4:30 AM on the 9th). The estimate of 0.5-inches of snow on the ground is generous, as the pattern of snow cover was mottled, with patches of green grass showing through from overnight melting.
12/10/2009 7:00 AM 0.42 5.5 0.42 5.5 0.42 Temperature and relative humidity at 7:00 AM: 1°F and 63%; dew point temperature: -12°F. Light snow began falling at about 10 AM on the 9th, with a combination of increasing snowfall and high winds creating blizzard-like conditions by mid-afternoon. Heavy, wind-driven snow continued falling until at least 9 PM on the 9th, when I went to bed. Winds in excess of 40 mph created drifting conditions that made precipitation measurements difficult. I measured 3.2 inches of snow on one side of the snowboard and 4.8 inches on the other side. Ten snow-depth measurements ranged from 0.5 to 15.0 inches, with an average of about 5.5 inches. A 4.8-inch core from the snowboard yielded 0.27 inches of water, while a 5.5-inch core from the front yard yielded 0.42 inches. Given that (1) virtually all snow had melted in the yard yesterday morning, and (2) the snowboard was subject to strong winds, I have used the values of 5.5 inches and 0.42 inches for both New Snowfall and Total Snow on Ground. A mere 0.03 inches of melted snow was captured in the rain gauge.
12/11/2009 7:00 AM T 0.1 T 4.0 0.39 Temperature and relative humidity at 7:00 AM: 8°F and 56%; dew point temperature: -6°F. NEW SNOWFALL: Extremely light snowfall was noted in the AM and early afternoon on the 10th, with little accumulation noted. I had 1 inch of snow on the snowboard this morning (0.10-in melted value), but suspect that all or most of that was due to drifting. Based on the minimal accumulation of new snow in the driveway, I estimated new snowfall at not more than about 0.1 inches. SNOW DEPTH: Extremely variable due to extreme drifting. Five points in the front yard had a median depth of 4.5 inches (range 4.0-4.5). In the wind-scoured one-half of the back yard, snow depth was about 0.5 inches (i.e., the tips of the grass blades were just visible). In the other half of the back yard, snow depths at five points ranged from 2.5-7.0 inches with a median of 4.5 inches. The deepest drift in the yard was 12.0 inches. Factoring in the wind-blown area, I estimated an "average" snow depth of approximately 4.0 inches. MELTED VALUE FROM CORE: A 4-inch core sample yielded 0.39 inches of water.
12/12/2009 7:00 AM T T T 3.5 0.40 Temperature and relative humidity at 7:30 AM: 16 degrees F. and 64 percent; dew point temperature: 3 degrees F.

PRECIPITATION was in the form of light rain in the early AM on the 13th. SNOW COVER: 50 percent. SNOW DEPTH: Depths at 11 random points ranged from 1.5 to 7.0 inches, with a median of 2.0 inches. Average snow depth calculated at 2.0 inches times 0.50 = 1.0 inches. MELTED VALUE FROM CORE: A 2-inch core yielded 0.44 inches times 0.50 = 0.22 inches.
12/15/2009 7:00 AM 0.03 0.1 0.01 T 0.01 Temperature and relative humidity at 7:00 AM: 30 degrees F. and 73 percent; dew point temperature: 20 degrees F. Light snow at time of observation. A very light mist prevailed throughout much of the AM and early PM on the 14th. I awoke to a light coating of new snow on the ground at 6:00 AM on the 15th. Precipitation was a mixture of rain (0.02 inches) and snow (0.01 inches). SNOW COVER from old snow had been reduced to 10 percent or less by 5:00 PM on the 14th.

The very light dusting of fresh snow on the ground this morning is not enough to measure. SNOW Cover: 10 percent. SNOW DEPTHS on snow-covered areas ranged from 0.5 to 4.0 inches, with a median of 1.0 inches, for an overall average of 0.1 inches or a Trace.

All precipitation was in the form of sleet or freezing rain. Sleet began falling late in the afternoon on the 23rd, followed by light, freezing rain later in the evening. There was a 0.1-inch layer of ice on top of the snow. Likewise, local roads were covered in a thin sheet of glare ice, making travel difficult, if not impossible. Strangely, there was no ice coating on tree branches.

A brief, very light snow flurry between 10:00 and 10:30 AM on the 1st produced no measurable snowfall. Light snow that began in the after-dark PM hours of the 1st or early in the pre-dawn hours on the 2nd was still falling at the time of observation.
2/3/2010 7:00 AM 0.06 1.5 0.06 4.0 0.44 Temperature and relative humidity at 7:00 AM: 21 degrees F. and 77 percent; dew point temperature: 13 degrees F. Light, extremely fine snow fell throughout the AM on the 2nd. In the early afternoon of the 2nd, snowfall became heavier, with large, fluffy flakes. Heavy snow continued throughout much of the afternoon before diminishing by about 4:00 PM. Temperatures had warmed to just above freezing at noon on the 2nd, with the result that snow falling on the snowboard melted as fast as it fell, making measurement of new snowfall difficult. My estimate of 1.5 inches was confirmed by the accumulation of new snow on top of the old. Snow cover: 100 percent.

Light mist at time of observation, with frozen droplets on outside of rain gauge; measurable precipitation was from snowfall. The freezing mist was enough to cause icing conditions on local roads. Light snow throughout the AM on the 16th. Heavy snowfall in the early afternoon on the 16th, but snow was melting about as fast as it fell due to temperatures just above freezing. There was a light coating of ice on the snowboard indicative of snow that had melted and then froze overnight; as a result, reported precipitation is probably an underestimate.
2/18/2010 7:00 AM T T T 10.0 1.55 Temperature and relative humidity at 7:00 AM: 32 degrees F. and 79 percent; dew point temperature: 24 degrees F.

A light mist that began falling about mid-afternoon on the 21st had changed over to heavy snow by 7:00 PM. Heavy snow continued throughout the evening hours, but with little accumulation because of temperatures at or just slightly above freezing. This morning was one of the few times I've measured less liquid precipitation on the snowboard than in the rain gauge (0.56 inches vs 0.71 inches). A heavy, wet, slushy snow, causing slippery driving conditions on local roads.
2/23/2010 7:00 AM 0.05 0.5 0.05 8.5 2.01 Temperature and relative humidity at 7:00 AM: 28 degrees F. and 78 percent; dew point temperature: 20 degrees F. Heavy snow flurries between 7:00 and 8:00 AM on the 22nd produced about 0.5 inches of snow that quickly melted as temperatures rose above freezing. Light snow flurries between 4:00 and 6:00 AM on the 23rd produced a mere dusting of snow on the ground.

Extremely light snow flurries at time of observation. Light snow began falling about 3:00 PM on the 23rd and continued until about 7:00 PM. There may have been additional light flurries overnight. Snow on ground is becoming icy and granular from repeated daytime thawing and nighttime freezing.
2/25/2010 7:00 AM T T T 7.5 1.94 Temperature and relative humidity at 7:00 AM: 20 degrees F. and 69 percent; dew point temperature: 9 degrees F. Light snow flurries between 7:00 and 8:00 AM on the 24th and again between 6:00 and 7:00 AM on the 25th produced no measurable snowfall. Snow on the ground is now quite solid and compact to the point that a 250 lb person can walk on top of it and barely sink in.
2/26/2010 7:00 AM T T T 7.5 1.96 Temperature and relative humidity at 7:00 AM: 25 degrees F. and 74 percent; dew point temperature: 16 degrees F. Light snow flurries much of the afternoon and evening hours on the 25th failed to produced measurable snowfall. Heavy winds overnight caused some drifting, which was ameliorated by the hard-packed snow.

6/6/2010 7:00 AM 0.56 M M M M Temperature and relative humidity at 7:00 AM: 60 degrees F. and 78 percent; dew point temperature; 52 degrees F. Three distinct episodes of precipitation in the last 24 hours: (1) a light but persistent rain that began falling at about 11:00 AM on the 5th prevailed until about 2:00 PM; (3) about a half-hour shower between about 6:00 and 7:00 PM on the 5th; and (3) a heavy downpour between about 11:30 PM on the 5th and 12:30 AM on the 6th. The first two rainfalls produced about 0.24 inches combined, the remainder of today's total occurring during the latter storm, which was accompanied by extremely strong winds, which tended to drive the rain in horizontal sheets. It's anyone's guess as to how much of the actual rainfall from this storm was actually collected in the gauge. The occurrence of a tornado was documented about 10 miles north of this station.
