.UPDATE...
Issued at 1107 AM EST Tue Jan 21 2025
This morning the main question has been where will the dry air win
out. We are doing an 18z sounding to get a better picture of
this line and will have more of an update as that comes in.
Currently there is a deep layer of dry air at 850mb but our
dendritic growth zone is almost saturated at this point. We have
been receiving reports of flurries despite this and are seeing a
potential moisture surge coming in from Alabama. This along with
the 12z models coming in gives us a little more confidence that
the 850mb layer will moisten up but we will know more with this
sounding. Have just slightly upped snowfall totals to account for
this trend but only by a couple tenths of an inch. Will keep an
eye on that though.
