Short Term Forecast Discussion Atlanta NWS FFC

SHORT TERM /Today through Wednesday/...  Primary concern is onset and
magnitude of light snow beginning this afternoon. Near term hires models in
good agreement with primary model guidance that band of light snow should
move into far NW GA around noon to 1p today and slowly moving south toward
the rest of north and west GA during the afternoon. Since this system is
more of a post-frontal overrunning rather than an eastward-moving low
pressure system to our south, it`s going to be difficult to see much
precipitation, especially considering the strong push of cold/dry air
behind the front. That said, with sfc temps eventually going well below
freezing, it won`t take much precip to cause impacts on roads. Based on
latest QPF and temperature guidance, our snow amounts went up just a touch,
but still mostly remain below 1.0 inch. Another change we saw in recent
guidance was the development of a secondary band of light snow over
southern AL into westcentral GA during the evening hours. This band could
produce up to 1 inch just by itself as it pushes from the LaGrange and
surrounding areas into the south ATL metro.  By Wed morning, temps should
have bottomed out while wind speeds peak. At this time, WCI values are in
the single digits to around zero over much of north and west GA and well
below zero in the mountains. Wind chill warning criteria may be met in a
few spots in the higher elevations but have kept this area as a separate
segment in the advisory for now.  Black ice may be an isolated problem
Wednesday where snow amounts are an inch or higher, but with such light
amounts of liquid- equivalent precip, strong winds, abundant sunshine and
dry air, do not believe there will be much to refreeze.  SNELSON  && ECMFW Chart for Atlanta Forecast Chart

East Cobb Weather - Atlanta Conditions, Forecast, Advisories

This station is located in northwest Georgia outside Atlanta. We are near Marietta and Roswell in Cobb County, often coined "East Cobb". We have a somewhat continental type climate, with cool winters and hot summers, but also with abundant precipitation, averaging over 50 inches per year, and well distributed through the seasons. Most of this moisture comes from the Gulf of Mexico.

Winter morning low temperatures average just below freezing, with highs around 50 F, but wide ranges are possible, with some winter highs near 70, and lows occasionally falling to near zero F in extreme arctic outbreaks. Snow falls at some point in almost every winter, but is not very frequent. Summers in Marietta are hot and humid, with morning lows about 64-70 F and highs about 85-91, with 100 possible. Thunderstorms occur many summer afternoons and can be severe in spring.
