What forecasters said that day

The local office's own words before this freeze warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Atlanta, GA wrote its last area forecast discussion before this freeze warning went out at Mar 12, 2:48 PM EDT, 13 minutes earlier.

Area forecast discussion, Mar 12, 2:48 PM EDT, 13 minutes before
Area Forecast Discussion
National Weather Service Peachtree City GA
248 PM EDT Mon Mar 12 2018

.SHORT TERM /Tonight through Tuesday Night/...
Clouds continue to quickly erode this afternoon as the upper low
that kept lingering showers across portions of the area this morning
exits into the Carolinas. A strong pressure gradient has led to
gusty northwest winds today which will continue into this evening. A
Wind Advisory will remain in effect for the majority of the CWA
through 7 PM EDT this evening to account for sustained winds of 20-
25 mph and gusts as high as 35 to 40 mph. The northeast Georgia
mountain counties will remain in the Wind Advisory through 2 AM
where higher gusts will linger into the overnight hours.

Despite breezy conditions, overnight temperatures should drop into
the 30s area wide with upper 20s in the higher elevations of
northeast Georgia. While temperatures may not drop below freezing
for more than two to three hours outside of northeast Georgia, opted
to issue a Freeze Warning from 6 AM through 10 AM Tuesday morning
for portions of north Georgia where the frost/freeze program has
already begun.

Northwest winds on Tuesday will remain breezy, though below Wind
Advisory levels. After below-normal highs in the 50s under sunny
skies on Tuesday, low temperatures by Wednesday morning will be
colder than Tuesday morning with a higher degree of confidence for
widespread freezing temperatures across north and portions of
central Georgia. A Freeze Watch has been issued to highlight this
potential.

RW

.LONG TERM /Wednesday through Monday/...
No major changes made to the extended forecast. The middle of the
week is still expected to be dry with rain moving in Fri and into
the weekend. Strong high pressure will begin to build eastward
over the state Wednesday, but begin to shift southeastward over
Florida for Thursday into Friday. The high center should move
completely offshore the Florida peninsula by early Saturday.
Meanwhile, an old frontal boundary will begin to slowly shift
southward out of the Northern and Central plains and into NW GA by
Friday afternoon. At the same time a second high center builds
southward from the Great Lakes. This front is expected to meander
southward over much of the state for the weekend, until another
cold front which develops out of the southern plains moves in
early next week. There is very little instability with theses
systems so have only showers in the forecast for now...No thunder.

Colder than normal temperatures are expected during the middle
part of the week. With overnight min temps around 10 degrees below
normal for Wednesday and Thursday morning, freeze/frost headlines
will be needed. Temperatures will warm up quickly for the end of
the week as the flow turns more SW with next two frontal systems.

.FIRE WEATHER...
Very low dewpoints/humidities expected Wednesday and Thursday.
Currently, Thursday looks like the driest day with RH values at
or below 30 percent for the entire outlook area. Wednesday, RH
values are just slightly higher will the southern two thirds of
the outlook area at or below 30 percent. However, models typically
forecast dewpoints a bit too high in NW flow. So, would not be
surprised to see the dewpoint values a bit lower for both days as
we get nearer to the middle of the week. Breezier conditions will
linger into Wednesday, with sustained surface wind speeds 10 to
15mph across the outlook area. Winds should diminish a bit on
Thursday, with sustained values currently expected to be around
10mph.

&&

.AVIATION...
18Z Update...
Any lingering MVFR ceilings will continue to rapidly clear by
around 18-20z at all TAF sites with mostly clear skies expected
thereafter. Gusty NW winds will continue this afternoon with the
highest winds of 15-25kts with gusts 25-35kts expected through
around 23z. Overnight wind speeds will settle into the 8-12kt
range. Gusts in the 18-22kt range will return by Tuesday
afternoon.

//ATL Confidence...18Z Update...
High confidence on all elements.
