  1. HAS ANYONE NOTICED PEOPLE AROUND THE ARTIC CIRCLE ARE SEEING RED AURAROS AT UNPRECEDENTED LEVELS. THEY CAN’T EXPLAIN IT, RIGHT? HOW ABOUT OUR MAGNETIC FIELD IS WEAKER AND THE SOLAR WIND IS PENETRATING FURTHER CAUSING THEM. IS THIS THE BEGINNING OF A MAGNETIC FLIP? MAYBE BECAUSE OF THE EXTREMELY LOW SUN SPOTS?

  2. Must be same storm system. Calling for near freezing temps in Arizon down to 3000-3500′. Hopefully er get the .5-1.5″ of precipitation they are predicting. We’ll take it anyway we can get it right now.

  3. Major cold blast to Texas, with snow in Texas, unbelieveably, this weekend. This used to be early for Minneapolis to have snow. Minneapolis already had record snow last week for the date. 8 inches at the airport.

    …BLIZZARD WARNING IN EFFECT UNTIL 9 PM MDT SATURDAY…

    * WHAT…Blizzard conditions expected. Total snow accumulations of
    8 to 16 inches, with isolated amounts approaching 20 inches in
    the mountains.. Winds gusting as high as 40 mph.

    * WHERE…Northern Rocky Mountain Front, Eastern Glacier,
    Eastern Pondera, Southern Rocky Mountain Front and Eastern
    Teton.

    * WHEN…Until 9 PM MDT Saturday.

    * IMPACTS…Travel could be very difficult to impossible,
    especially from midnight tonight through early Saturday
    afternoon. Widespread blowing snow could significantly reduce
    visibility. The cold wind chills as low as 25 below zero could
    cause frostbite on exposed skin in as little as 30 minutes.

  5. Once that wet snow freezes its should provide a solid base for the snow mass which will follow untill late spring next year.
    The Snow mass stats will go though the roof this winter.
