From FFC AFD:
Both the
GFS and Euro agree on the highest chances of
precip coming during the day on Tuesday, with precip falling behind
the cold
front. The Euro hints at some
snow flurries behind the line
of storms where the
GFS is much more bullish with light snow
coverage with chances all the way down to central Georgia. Both then
clear out with high pressure settling in with a weak
shortwave
moving through Wednesday night. the Euro keeps this wave dry while
the
GFS hints at light
snow flurries possible for far North Georgia.
The
GFS-FV3 on the other hand, elongates the cold
front, pushing it
through slowly on Wednesday. It`s much drier than the Euro and
GFS,
but still has a strong signal that we could see so mixed/frozen
precip through the area on Wednesday instead, even into central
Georgia. The current forecast blends these 3 scenarios with each
having some consistency to their claims from the previous night.
Guidance has been putting a signal for some winter precip around
this time for the last several days with no clear indication on
which way Mother Nature will go. Seemed appropriate to include at
least a
slight chance of each possibility. Although if you hold my
feet to the fire, I`
d lean towards the Euro (
front Tuesday, little
chance of frozen precip with higher temps and dry the next several
days afterwards).
