Good morning!

Today marks the change in the weather. The next three days (including today) will see showers and thunderstorms returning to the north Georgia area. Here are the latest thoughts from the Atlanta NWS:


Current radar loop shows showers moving into South and Central GA
ahead of developing system in the gulf. The persistent upper level
ridge centered over the east coast of Florida and continued
southwesterly flow aloft will push deep Gulf moisture into north and
central Georgia Today and Wednesday.
This moisture, combined with a
series of shortwaves along the old frontal boundary embedded within
the upper level flow and isentropic upglide, will support the
development of showers Today. Increased clouds this morning across
the entire state with rain chances increasing from South to North
through Tonight. Likely to categorical PoPs are expected across the
entire area through Wednesday
. Instability in fairly weak today but
things increase a bit especially across central GA Wednesday. Have
introduced a slight chance of thunder Wed afternoon across the area.

This moisture will remain over the area ahead of a strengthening low
pressure system that will approach and then move through the area
Wednesday and Thursday.

At this time, Wednesday into Thursday appears to have low severe
threat, with the more active weather expected Thursday afternoon
into the evening hours - prime trick-or-treating time.
continue to be in good agreement with the timing of the cold front
through the area. There is some uncertainty whether the front and
associated stronger convection will be through the metro-Atlanta
area by 00z, and expect this timing to be better pinned down over
the next 24-36 hours.

Although the better dynamics remain north of the area, there is
still enough low level shear and instability to produce isolated
strong to severe storms. At this time, damaging winds will be the
primary threat.

Total QPF through Thursday is expected to run 2 to 3 inches over
far north Georgia, and under 2 inches elsewhere. Isolated pockets
of up to 3.5 inches or more are possible, particularly in the
higher elevations of north Georgia.


The official NWS rainfall forecast looks like this through 8 AM Friday morning.


Friday and Saturday mornings may bring freezing weather for many in the mountainous areas, and most likely frost for the rest of us. These are the GFS lows for Friday morning. 



This mornings bigger picture shows the deep trough that is diving across the Rockies this morning with single digit temperatures over much of Montana and Wyoming. Moisture is gathering ahead of the cold front and that will be combining with deeper Gulf moisture to enhance the chances for precipitation today through Thursday. 



Clouds are already starting to stream over the north Georgia area, and those will lower and thicken as the day progresses. Here's a look at the current radar image. 



As soon as I can get a good visible satellite image I'll post it here. 

Down here in Sarasota it's sunny and almost 80 degrees, and I'd trade this for what you are going to have in a heartbeat. I'm over hot and sunny just like everyone else was over it up there, so I hope everyone appreciates the clouds, the rain, and the cooler temperatures today! 

Have a wonderful day! 🙂
