Most guidance seems to have two shortwaves coming down near mid-month that we can sort of follow now....but that can obviously change at this lead time. The second one looks better to me....which would prob be in the 1/15-1/17 time range (timing varies by model guidance and cycle)....the first one looks like it's struggling with wave spacing and also antecedent airmass is poorer. So if we happen to grab anything out of the 1/13-1/14 period, it's pure gravy IMHO.
