Wednesday morning

Fell asleep while reading last night, please forgive this late and very bleak forecast. Cold today, obviously. High of 13, low of 13. Possibility of snow tonight, but more on that later. The thing to know now is that tomorrow will be very very cold. The temperatures will drop into the single digits, the wind will pick up speed, and tomorrow night will bring death weather with wind chill values as low as -20. I suggest that you avoid drunken outdoor activities. The temperatures will begin to rise very slowly on Christmas Eve, but I don't think we will see 30 until at least Monday.
As for this snow it depends entirely on whether this system that just passed over us is moving slow enough, and has enough strength, for its winds to wrap around and cross the lake again from the northeast. Two forecast models say that it will, and one says that it won't. I am inclined to believe that it won't, but if it does we can expect about two inches of snow around midnight tonight.
