Once promising storm for Monday fizzling
Friday, February 13, 2015
After another couple of spectacular days today and Saturday, the once promising storm traveling through the dominant west coast ridge is expected to be considerably weakened as it approaches our area. There was hope in the last forecast that some phasing would occur between a loitering cutoff low near Baja, Pacific energy impacting the west coast and waves of cold air circulating around the Hudson Bay vortex. However, the west coast ridge will not only weaken the storm entering the west coast on Saturday, but will keep the Baja low to our south and the coldest air to our north and east.
By Sunday, likely early in the day, the weakened Pacific storm will bring some light showers to our area with only and inch or two of accumulations expected on the hill. Quickly following this wave will be a surge of moderately cold air from the north, bringing more persistent snows for Monday along with significantly colder temperatures. There is uncertainty with regards to the western extent of this cold air, but currently I expect 3-6” of snow during the day Monday.
Even though the threat of snow looks to end later Monday, we will be seasonably cool but mostly dry next week as waves of cold air rotating around the Hudson bay vortex graze our area.
There is another storm forecast for around next weekend or the end of the workweek, but this also might be weakened by the west coast ridge, so the forecast for then is uncertain.
