Short term /Monday through Tuesday/...
chilly start to the period this morning with some of coolest temperatures
still expected...many areas looking to dip into the low 40s. Some
locations may get lower with optimal conditions for radiational
cooling lacking any cloud coverage...even the cirrus from before.
Could not rule out a few spotty areas of frost in some of the higher
elevations of north Georgia.

Models in decent consensus with timing of next shortwave trough
pushing into the north by 00z this evening and weak surface front
trailing behind. System continues to be moisture starved and lacking
good lift so have kept area dry but increase some cloud coverage in
the far this afternoon into evening. Next surface high builds in from
the north and enhances the gradient winds for Tuesday. Ridging and
dry conditions should linger as the upper trough energy cuts off
northeast of the area. Temperatures should moderate back to near
normal values today through Tuesday.

Long term /Tuesday night through Sunday/...

Long term period begins with closed upper low moving offshore the
middle Atlantic coast while at the surface an area of high pressure
bridges across the Great Lakes with influence all the way south
through our area and the Gulf Coast. As strong upper high builds
over the middle section of the country...local area will remain in a
dry northwest flow aloft and generally weak high pressure at the
surface. Will continue to monitor for potential tropical/hybrid
systems late in the period but for now will remain with a dry
forecast for the next seven days.

12z update...
VFR conditions expected through period with a few sites possibly
having brief initial MVFR visibilities this morning. Possible cumulus field
this afternoon but thinking just few coverage then middle level
moisture with next disturbance looks to bring scattered coverage in 8-12
kft range tonight. Winds generally calm or light southeast
initially then swinging SW after about 16z. Expect light west to
calm overnight then increasing during the day Tuesday out of the
northwest near 7-10 kts.

//Atl confidence...12z update...
medium on initial visibilities.
High all else.
