Winter Storm Update

Last night the Euro and GFS weakened the low pressure that is expected
to bring us winter precipitation on Sunday/Monday. It was discouraging
for some folks. But at this point, the NAM and GFS are the computer
models to be watching, and we're just now entering the NAM's sweet
area for forecasting.

So with that...
This morning, the NAM and new GFS runs have actually strengthened the
low to the point to where those of us in North Georgia are in a
bullseye of snow. Take a look at this snow accumulation loop from the
NAM this morning and watch the last two frames. The times are UTC
times but the last frame is approximately 1 pm on Monday.

Folks, according to this model run (and this is no prediction yet)
we're looking at possibly 10"+ of snow here in Gwinnett County. That's
some serious snow.

Right now what we're focused on is the timing and strength of the low
and exactly where the freezing line will fall. What we do know is that
many people in the south will have a considerable amount of frozen
precipitation no matter what happens. This mornings forecast
discussion from the National Weather Service here in Atlanta alludes
to Watches/Warnings being posted, possibly as early as this evening.

We'll keep you posted.
