    Snow to Hit Thursday Night/Friday Morning...Christmas Snow Small

    12/21/2011, 5:57:32 AM


    1. The first problem will be the snow coming Thursday night into Friday morning as shown on the map below. The second storm that is currently over Baja will move northeast, pick up Gulf of Mexico moisture and head into position over Long Island by Friday morning. Cold air will filter south behind today's storm and just catch the rain area coming northeast to produce a swath of 1-4 inches of snow. The high country in that area will see up to 6-8 inches of snow and even Boston has the chance of getting 3 inches of snow. Once that storm is gone, we are on to the Christmas storm.

    2. One thing before the Christmas storm, Denver and the front range will receive another 2-6 inches of snow today into tonight as cold air presses down the High Plains. Even New Mexico will see another 2-6 inches of snow with this system Thursday. Places like Albuquerque could have its biggest snow of the season with 4-8 inches Thursday into Thursday night.

    3. The only way I see snow from the third system is for the rain area to catch the cold air and produce a swath of wet snow on Christmas Day across Maryland, southern Pennsylvania into New Jersey. A sneaky cold air mass will come south from Ontario and it will be much colder despite what the computer models are predicting. That cold air may just catch the rain with the third system to produce a swath of wet snow. I still do not believe a major storm is coming due the positive NAO. Even the week prior to New Year's, we still have the same problem with storms shown on the models and a positive NAO.
