Here is one of those weird discrepancies in Internet Weather forecasting: Right at the moment, Weather Underground is stating my temperature here in Park Rapids, Minnesota is -13 degrees, my thermometer outside my picture window is showing -20 degrees and because it is close to the window, it is likely a few more degrees even colder! The temperatures shown at the banks in town would likely agree with the Weather Undergrounds temps. I am a ways North of town and surrounded by swamp land, which means I am in low country and cold air does seek lower elevations. This discrepancy will grow larger as the temperature descends and decrease if there is wind. I have seen temperatures as low a 55 below and at that temperature Liquid Petroleum gas starts to solidify and I've had to go out and throw warm water on my LP Tank to get the gas to flow again. Once the sun comes out the problem ceases and we don't get real cold temperatures, unless it is clear out.
You might ask why I live where it can get this cold? I just love it and it does keep the population down. It is also very beautiful here, the pines have snow "flocking" on them right now. I get deer and birds and all kinds of critters passing though my property and a Red Fox lives in the culvert at the end of my driveway.
At these temperatures; however, it is too cold to go out an bank the house. So, it is extra cold in the basement where my layout is, so may not spend much time working on the layout.
