An updated wind advisory, which warns of gusts up to 40 mph, is in effect through midnight for most of north and central Georgia, including Cartersville and Bartow County. A tornado watch also is in effect until 4 p.m.
A strong upper-level trough and its associated surface cold front will push through the state today," NWS' hazardous weather outlook says. "The squall line is expected to produce strong, damaging winds, isolated tornadoes and frequent cloud-to-ground lightning. Any tornadoes will likely be brief with little notice."
The line of storms is expected to push into northwest Georgia in the morning, track through metro Atlanta by mid-afternoon and along an Athens-to-Macon-to-Americus line by early evening. Thunderstorms will produce heavy rain resulting in a widespread 1.5 to 2 inches or more across portions of north and central Georgia.
A flood watch is in effect for Bartow through this evening.
Strong winds are expected to develop as a storm system and cold front move into the Cartersville area Tuesday night and Wednesday.
In effect 5 a.m. to 7 p.m. Wednesday, a wind advisory for north and central Georgia, including Bartow County, warns of 15 to 25 mph winds with gusts up to 35 mph, which make driving difficult.
"Showers and a few thunderstorms will accompany these winds, but it should be noted that very strong winds will be possible outside of any shower or thunderstorm activity as well," the advisory says. "Recent rains and the additional heavy rainfall anticipated from this system will allow for trees to be uprooted with greater ease."
A squall line capable of producing widespread damaging winds and isolated tornadoes is expected to cross the area Wednesday night, according to NWS' hazardous weather outlook. Frequent cloud-to-ground lightning and heavy rainfall also can be expected with thunderstorms.
Cartersville has on tap for Wednesday a 100 percent chance of showers and thunderstorms, some of which could be severe, according to the NWS forecast. The high should reach 65 and gusts of wind could be up to 40 mph before the low Wednesday night dips to around 33 and the windy weather tapers off.
