WATCH NOW: Breaking down Friday's storm threat for Metro Atlanta
Thunderstorms are in the forecast for Friday. Let's break down the timing of these storms and discuss the potential for wind damage.Posted by Christina Edwards on Thursday, March 2, 2023
The Storm Prediction Center has outlined a “Slight Risk” for scattered severe storms on Friday, which means they will be short-lived and isolated, but potentially intense with damaging winds the main impact.
Warm and humid air will be in place over North Georgia, which is favorable for thunderstorms to develop. A cold front will push into Georgia Friday afternoon, sparking up thunderstorms along the edge of the front.
Enough strong winds aloft, or high above the ground, will be present to generate potentially damaging wind gusts within these storms. Outside of the rain, non-thunderstorm wind gusts may be as high as 30- 40 mph. This is strong enough to knock down trees and powerlines. As a result, a Wind Advisory will be in effect throughout the day on Friday.
Low level wind shear -- change of wind speed and wind direction from the surface of the ground to one mile above -- will be present, and there may be enough to produce a tornado or two.
However, the low pressure system responsible for the thunderstorms will be moving away from Georgia, potentially limiting the amount of energy available for the storms to tap into.
As a result, storm development may be limited, as illustrated in the two model forecast animations below.
For Metro Atlanta, a few showers may be present in the morning but the potential storm window mainly includes 12pm through 4pm Friday.
Even with a conditional threat for severe storms, remain weather aware for gusty winds that may knock down trees and power lines.
