JOESTRADAMUS: SNOW POSSIBILITIES LOOM AHEAD (DECEMBER 4, 2017)

Snow Possibilities Winter Pattern Developing

When it became evident that we were seeing the upper pattern evolving into a wintry one, it has been my contention that with a pattern like this, it would be likely that an early snowfall for somebody in our area was going to happen. Today's weather models leave me unchanged in this view. The colder air pattern begins to establish itself beginning on Wednesday after the cold front to our west passes through. The first possibility would come on Friday as a wave develops on the front to our south but I'm actually less concerned with that and more concerned with the second arm of energy that swings in on Saturday. Weather models show that the wave for Friday will be flat and weak. This could keep us in clouds but the bulk of the precipitation will likely be offshore. However a weak less developed first wave leaves room for a second low to develop on Saturday and both the European and the GFS model are going down this particular road.

What is happening is that energy from the Great Lakes is swinging eastward from the Ohio Valley. The first wave goes out to the northeast but by staying weak, it leaves behind a lot of moisture just to our south and east which then becomes available as the upper trough swings east..READ MORE AT http://www.meteorologistjoecioffi.com/index.php/2017/12/04/snow-possibilities-winter-pattern-developing/
