High pressure remains anchored to the south of central New York and will continue to keep our weather quiet into Friday. However, later Friday a cold front will approach from the north and that front will spread in a few extra clouds. That front will move through tomorrow night and, although most will stay dry, there may be a few sprinkles or flurries across the region.
Behind the front will be a slightly cooler air mass for Saturday. Even though temperatures are likely to be in the upper 30s to near 40 that is actually close to normal for the middle of December.
Meanwhile, along the far west end of Friday night’s front, low pressure is forecast to form in the central Plain States. This storm will move east and northeast to a position somewhere in the lower Great Lakes region by Sunday. This will result in an increase in cloud cover Saturday night with rain or perhaps wet snow possible on Sunday into Monday. Since low pressure is weakening as it approaches, we think the precipitation for us will be generally light in nature.
A second, stronger area of low pressure will track across the Gulf Coast Monday then take a turn to the north along the East Coast Tuesday into Wednesday. The new computer models today show a trend of tacking this storm farther east with less of an impact for us here in central New York. There is still some uncertainty this far out in time so we’ll continue to monitor the trends over the next few days.
