The National Weather Service in Peachtree City says that the formation of widespread fog is a possibility tonight for most of North and Central Georgia, including Coweta County.

Fog conditions will be dependent on the amount of wind in the area. Presently, calm winds are forecast overnight in Coweta County which could result in dense fog.

NWS is also warning of a strong storm system approaching Georgia late Christmas Day (Tuesday). A cold front is moving west to east into Georgia and the instability and vertical wind shear will be enough for isolated severe thunderstorms to develop.

Those severe storms will be mainly across the western edge of Georgia between 3 a.m. late Tuesday and 7 a.m. Wednesday.

The main concerns will be isolated tornadoes as well as strong, damaging winds in excess of 60 mph.

The present NWS forecast for Newnan and Coweta County on Christmas Day calls for occasional rain, with thunderstorms possible after 1 p.m. Expect a high of around 61 with calm winds becoming Southeast at 5 mph. The rain chance is 100 percent with amounts between 1/2 to 3/4 of an inch.

On Christmas night, again a 100 percent chance of rain – some severe – with a low of 48. Southeast winds at 10-15 mph, gusting to 25. 

And on Wednesday, a 50 percent chance of rain before 1 p.m. Mostly cloudy with a high near 51. Southwest winds 10-15 mph, then increasing to 15-20 mph in the afternoon.
