A low pressure system is expected to produce a squall line that will pose a significant severe weather risk over much of the Gulf Coast this afternoon and evening. This line will cross Georgia tomorrow morning and afternoon, and even if it should weaken overnight before moving in, there is always a possibility for generally severe weather south of the I-85 corridor tomorrow. The Storm Prediction Center has placed all of southern and much of central Georgia under a slight risk (level 2 out of 5) of severe weather tomorrow.
Rain is expected to start moving into northern and central Georgia after midnight tonight and continue well into the wee hours of the morning. The main line of showers and stronger thunderstorms will begin to move west of the Atlanta metro area, west-central Georgia and southwest Georgia near sunrise tomorrow. The line will move fairly quickly from west to east, and any location should only be impacted by the main line for a few hours at most. The line is expected to begin to slowly weaken as it moves eastward from Georgia later in the afternoon, but may remain strong, and as the sun sets tomorrow, the line is expected to move to the off the Georgian coast.
The main danger with these strong/severe thunderstorms will be damaging winds, but a few tornadoes are also possible, especially in southwest Georgia. Gusty winds will also be possible outside of thunderstorms tomorrow as well, and a wind advisory has been issued for all counties in the NWS Peachtree City and Tallahassee areas. Non-thundery wind gusts of 35-40 mph are expected tomorrow, with locally higher gusts possible.
Cooler and drier weather will move behind the cold front tomorrow afternoon and evening, and continue through Thursday, Friday and Saturday. Chances of rain will return on Sunday early next week.
