Most of North Georgia has been blessed with fantastic weather this weekend. Low dewpoints and a consistent breeze has kept North Georgia comfortable, even though temperatures are in the upper 80s and low 90s. Unfortunately this will be changing as we head into tonight. Already, we are seeing extreme north west Georgia have dewpoints climbing into the 70s, while the rest of us sit in the low 60s. In terms of temperature, it might be a bit cooler up there because of increasing cloud cover, it most certainly does not feel like it due to the high humidity. This trend of "humidifying" will sweep across Georgia going through the night with dewpoints in the high 60s and low 70s for most of the state.
Rolling into the evening hours, moisture will invade the rest of north Georgia which will bring chances for precipitation. The timing and the severe modes of this system is still under consideration, as short range models (the best for showing thunderstorms) have been rapidly changing for Northwest Georgia in the past couple hours. But pop up showers and thunderstorms are likely to start at around midnight tonight, mostly scattered in nature. Based on forecast models, most thunderstorms should be making their way out of north Georgia (south of metro Atlanta) by 6am Monday morning, with scattered light rain showers lingering an hour or two after for some of us.
All in all, most of North Georgia seems to be in the clear as we get closer to the event. New model runs show Northwest Georgia dodging mostly all thunderstorms as they dissipate going into the night. But later on tonight, the newer model runs are showing new storm cells developing from Birmingham all the way northeast of Atlanta moving to the southeast. These new cells are likely to not be severe, but some strong winds and scattered downpours can not be ruled out. Possible severe thunderstorms will be short-lived and isolated in nature. Precipitation totals tops out at a quarter of an inch for north Georgia.
