This part of Georgia is not as temperate as the coastal sections where warm currents in the Atlantic (while they do bring storms) tend to moderate temperature fluctuations. Mid-Georgia can be cold in winter and very hot in summer and in recent years they have had summer water shortages due to reduced rainfall.
Winter in McDonough has some snow and ice (and everyone panics and closes schools) but not enough of either to cause major problems generally. The drivers in Georgia could be aided by some lessons on how to drive on snow and ice because they do have some doozy of pile ups on the interstates here when things get slick. We northerners have the winter cautions ingrained in us so are able to handle the iciness a lot better than our southern brethern.

Springtime in this area is great because not only do you get the profusion of bulb plants that we New Yorkers are accustomed to but you get beautiful flowering of azaleas which we generally don't see until mid-summer.

Early summer in McDonough is okay but it tends to get sweltering by July and it stays too hot right through into September. This is the time of year I try to avoid visiting the area because of the darn heat.

Fall is nice here but not as colorful as we have up north where the trees change early and stay bright red, orange and yellow for a month or more. By Halloween, the evenings have cooled off enough to make for comfortable sleeping.
