Small snow pellets observed for a few minutes yesterday afternoon. First hard frost of the year this morning (-2 C) although no actual frost was seen on the ground probably due to windy conditions?
Dividing my 40 years of precipitation and of "first hard frost" observations into 4 decades, I can conclude that in the 80's, the first hard frost occurred on the average on Oct. 8th, on Oct 11th in the 90's, then on the 12th the following decade. The average hard frost date in the last 10 years has increased dramatically to about Oct 18th, which is also the date of this year's first frost. However, the portion of this increase over the 40 years due to actual climate hange and that due to the increased urbanization (from essentially a rural area to a more densely populated suburban area) is unknown.

First significant snowfall of the season. Light snow still falling at observation time. New snow depth of the order of 5" and quite moist, but both the melted snow in the gauge and the core sample taken over the ground yielded a melted value of only 0.17". New snow depth varies by as much as an inch from place to place. It would seem inappropriate to report its depth to an accuracy better than half an inch. |

The melted value from core of new snow was difficult to obtain, but the melted new snow collected by the gauge is an accurate indicator of water content under these conditions of calm winds. Depth of old snow is fairly even at about 4.5" over my backyard grass, resulting into 0.59" of water equivalent collected with the 4" gauge. |

A small amount, < 0.1" of hardened snow inside the gauge yields about 0.01" of equivalent water (but the input software would not allow me to enter "T" for the new snow depth in combination with the weighed 0.01" amount). Snow cover on the ground is "crusty" and varied; about one inch in shaded areas and no snow in locations exposed to the sun. The water equivalent of 0.15" has been obtained by taking a core where snow depth is 1" (yielding 0.30") and then dividing by 2 to account for an estimation of about 1/2" average snow cover. |

Core measurement over the board yields less weight of snow. Not sure why. Has some rain run off the board? It shouldn't have.
I made sure of removing all the freezing rain on the outside of the gauge, so I consider its measurement of 0.41" to be the proper amount of total precipitation. |

+0.5 C and light rain at observation time. Yesterday's snow has been greatly compacted by the subsequent freezing rain and rain down to about 3 inches. I would estimate yesterday's snow to at least twice that amount. Little branches have about 8 mm of ice around them. Did not take core sample over the board because it would not have been representative of the 24-h precipitation. |

Estimates of total snow and ice on the ground are uncertain as no two sptots on my backyard seem to have the same snow depth, varying from 7 to as much as 14 inches. The amount entered is thus subject to a high degree of uncertainty, considering in addition that there is a layer of ice right above the ground that cannot be sampled.

Its snow water equivalent of 1.14 was slightly less than the amount of 1.18 measured from the 10.5 inches of snow over the board so I took the latter as the amount of precipitation in the last 24 hours. The total snow depth on the ground of about 19 inches is an approximation.
Correction at 12 noon after little or no extra precip: Measurements taken at other locations around my house would indicate a higher snow depth of about 13.0 inches and a melted water equivalent of the order of 1.48 inches. I will thus correct my amounts to the average of my initial and current measurements, that is, 11.8 and 1.33 inches. |

Snow depth above the ground is variable as usual. The previous reading of its water content of 2.23" was probably in error, likely as a result of not having sampled the entire column of snow due to a hard layer just above it. Today's reading of 3.17" should be more accurate. |

In view of the latest measurement of 5.16" being higher than the previously reported amount, previous measurements probably sampled the snow only above the highest layer of ice. The lowest layer of ice just above ground is impossible to be sampled. Conditions this year makes this particular measurement very doubtful. |
