CTP being rightful caution in their afternoon update
KEY MESSAGE 2: Medium-range guidance remains consistent in
depicting a large-scale winter storm this weekend, tracking from
the mid-South across the Mid-Atlantic states.
The devil, however, will be in the details, with a tight
northern edge snowfall gradient expected to be at play. Where
exactly this gradient zone sets up is highly uncertain, with the
potential for it lie somewhere across PA.
In all probability, the highest winter storm impacts will be
south of the Mason-Dixon line, but again with a tight snowfall
gradient and the anticipation of heavy snowfall where jet
dynamics are maximized, this situation bears watching. Please
stay tuned for the latest forecast updates.
