North Georgia weather: Weakening storm line brings midnight downpours

ATLANTA - It looks like the severe storm threat for Monday evening is over, ushering some changes to the forecast, including a warm-up into the weekend.

All watches and warnings from earlier severe weather have been allowed to expire.

Storm threat levels

What we know:

A weakening line of showers and storms is continuing its trek across the state lines into north Georgia tonight. While the atmospheric setup is stabilizing, plenty of ambient moisture remains to trigger localized heavy downpours. No active watches or warnings are currently in effect for the metro area.

Showers linger overnight

What they're saying:

"I'm still tracking a couple complexes that are stretching across East and Middle Tennessee and then even some into north and central Alabama," said FOX 5 Storm Team Meteorologist Jonathan Stacey. "The general trend is for all of that action to really kind of converge on north Georgia as it moves farther to the east." 

Forecasters emphasize that while severe weather risks are over for the night, a few loud rumbles of thunder and gusty winds could pop up.

Overnight storm tracks

Timeline:

• Midnight to 2 a.m.: The leading edge of the storm line closes in on the Alabama-Georgia border, pushing heavy downpours from Lake Lanier down through Gwinnett, DeKalb, Coweta, and Fayette counties.
• Pre-dawn to Sunrise: The line continues tracking eastward, steadily losing its intensity and breaking apart.
• Tuesday Morning: Lingering cloud cover will slowly clear out, giving way to bright sunshine by midday.

Behind the weather

Big picture view:

A passing frontal boundary is helping to clear out the stormy weather while temporarily knocking down the summer humidity. This setup will pull down temperatures slightly below normal for this time of year, offering a brief break from typical late-June swelter.

Regional weather impacts

Local perspective:

Rainfall impacts will be highly sporadic and scattered across metro communities. While structural damage is not expected, isolated locations that sit under heavier downpours could experience brief ponding on roads.

Why you should care:

Even though severe threats have diminished, sporadic storms can still produce sudden gusty winds. Drivers during the early morning hours should watch out for wet roads and sudden drops in visibility during heavy downpours.
