Area Forecast Discussion
National Weather Service Jacksonville FL
855 AM EST Tue Jan 2 2018
.UPDATE...Will allow different advisories in effect until 10 am-
Noon to expire. Expecting mostly cloudy skies S of I-10 corridor
with some partial insolation north. Latest consensus temperature
guidance support current high temp forecast for Today. Will
maintain wind advisory coastal ne FL counties where seeing
30-35 mph gusts.
Did not adjust current Winter Storm Watch...although considered
addding Duval...Union, Bradford given threat to western portion
of those counties. To prevent risk of flip flop...decided to
defer to afternoon when warning/ advisory decisions will be made
based on latest guidance. Will be a very difficult decision given
a climatologically rare threat with potentially significant impact
for our area, and a shallow cold air pattern our model guidance
tends to do poorly with.

Anticipating generally VFR cigs Today...with worsening conditions
later Tonight.
