ATLANTA, Ga. (CBS46) - It will be a mild start on Thursday in north Georgia. The low temperature will range from the mid 60s in the normally cool spots to the low 70s in Atlanta. Look for sunshine through midday as the temperature rises into the mid 80s at noon and low 90s in many cities by 2-3 pm.

A cold front will swing through north Georgia in the afternoon and early-evening. There’s a low 20% chance of a passing shower or thunderstorm as the front moves through. Most will stay dry. The breeze will kick in out of the north-northwest between 10-25 mph in the afternoon and evening. The temperature and humidity will fall quickly Thursday night. It’s fitting as autumn begins at 9:02 p.m. EDT.

The temperature falls all the way to the mid 50s to low 60s by dawn on Friday. Look for a lot of sunshine and 10-20 mph breeze on Friday. The temperature will be in the 70s around midday and may briefly reach 80° in Atlanta in the afternoon.

The wind diminishes Friday night and the temperature dips into the 50s by dawn on Saturday. After the cool start, it will be a gorgeous day with sunshine and highs in the low to mid 80s. Sunday’s forecast is trickier as a front moves in from the west. Scattered showers and thunderstorms are possible sometime between midday and late-afternoon. The timing of the rain will determine the high temperature. If the rain arrives by midday, the high will be in the low 80s. If it holds off until later, it may reach the mid to upper 80s before any rain.

Cooler weather returns early next week. Look for lows in the 50s and highs in the 70s through midweek.

Latest on the tropics

We continue to watch a disturbance in the Southern Caribbean that may eventually reach the Gulf of Mexico and threaten the United States. There is a high likelihood that the system will become a tropical storm in the next 2-5 days. The long-range forecast is uncertain, but if it were to reach the Gulf of Mexico it would not be until early next week - at the earliest.

Hurricane Fiona is a category beast with 130 mph winds as it moves towards Bermuda. Thankfully, the storm will pass far enough west of the island to spare it from the worst it has to offer. Part of Nova Scotia and Newfoundland will not be so lucky as the storm slams into Canada early this weekend with 100+ mph winds possible.

Tropical Storm Gaston is a non-factor in the Atlantic Ocean. There’s a disturbance near Africa with a good chance of becoming a tropical storm, but it’s not much of a threat to anyone.
