Um, it has? From this afternoons LWX AFD:
Broad, highly anomalous ridging will build into the Arctic, sending
a deep upper low south into the northern Plains, Great Lakes and
Ohio River Valley by Thursday. The collision of this cold upper low
with warmer temperatures near the Gulf Stream will likely generate a
strong area of low pressure in the vicinity of the East Coast.
Details in track, strength, and timing remain uncertain, and overall
confidence remains low; however, it should be noted that most long
range guidance has been unusually consistent in hinting at a
potential wintry precipitation scenario late next week.
