10/3/2009 7:00 AM 0.12 M M M M Last night at 9:30, I went out to the front yard with my dog - it wasn't raining, but then I saw a car go down the cross street, just one house south of mine - it was pouring. Then I saw a car proceed from south of that street, and it was pouring, and once he crossed the street, and headed north, the rain let up - we were a mere 40 feet from the rain/no rain line. It was cool!

10/11/2009 7:00 AM 0.00 0.0 M M M The volunteer pumpkin plant (that was actually growing a pumpkin, about the size of a large eggplant now) was scorched by the cold. The spider plants I use in my pots around were not affected by the dip below freezing. The color here is still anecdotal - a lot of smaller trees with some spectacular color, but many of the larger trees just showing a fading of the summer green, and not a lot of color yet.

12/9/2009 6:00 AM 0.81 M M 0.5 M There was a bit of slush in the gauge, but it wasn't much - most of it was water. The walks are slushy, and sure to be a hazard as they freeze with the dropping temperatures. Last evening, it was a rain and sleet mixture coming down.

12/15/2009 6:15 AM 0.01 0.0 M T M Today there is hardly any snow cover. From 75-95% of the ground is bare.

12/20/2009 8:30 AM 0.07 T M 0.5 M It snowed lightly much of the day, but it was also above freezing for while, so it was melting/slushy. Now it's icy, with a dusting on top of the frozen slush.
12/21/2009 6:00 AM T T M 0.5 M Still just a dusting. There was some snow in the gauge, but too little to amount to anything.
