R.W.S Special Weather Statement
Potential Winter Storm to effect the area.
Low pressure developing over the Southeast USA early this afternon will continue to move East Northeast.This low pressure has tapped into a supply of moisture from the GOM. This area of low pressure will move thru the Mississippi Valley as it heads towards the Ohio Valley.
With a Greenland Block in place and a strong -NAO ..this primary will hit a brick wall of confluence and be forced to hand off its energy to a secondary area of low pressure. The development of this secondary low pressure is still not agreed upon by models. However, the area for development should be the Delmarva to just south of LI. WAA will spread out ahead of the primary low and will run over the top of lower level cold air. CAD will be firmly entrenched across the areas N & W of I-95.
The potential exists for a couple inches of snow followed by a long duration of ice. The potential exists in the above regions for .25-.50 The potential exists for a dangerous ice storm.
Please stay tuned for future statements about this potentially dangerous storm from R.W.S.
