Snow Storm #5: Preview

The short-wave progged to affect the forecast area Saturday appears well south of the Aleutian Islands on GOES-W this evening. It/s heading for shore in the PAC NW THU afternoon. GooFuS phases / amplifies this feature on Friday over the Great Lakes with remnants of a weakening upper LOW currently atop AK.

Saturday is still aways away; however...this storm...as currently depicted...has good upper air support (PVA; left exit-region of lifting jet max) for dynamic cooling and strong warm-air advection at 85H. The omega equation couldn/t be happier.
