Drizzle persisted through the morning commute, but lunchtime skies were partly sunny across metro Atlanta, and the afternoon drive home should be a dry one, forecasters said.

While skies were clearing in north Georgia, the extreme southern part of the state was experiencing strong storms Monday afternoon.

The National Weather Service said a possible tornado touched down about 11:30 a.m. just south of Valdosta. The Lowndes County Emergency Management Agency reported structures damaged at a forest products company, with one building collapsed and railroad cars overturned, according to the Weather Service.

Numerous wrecks were reported across metro Atlanta on the morning’s wet roads, including one involving a jackknifed tractor-trailer that had the Spaghetti Junction ramp from I-85 southbound to I-285 westbound shut down before daybreak. The ramp was reopened just before 8 a.m., but another truck wreck blocked several lanes of I-85 northbound at I-285 later in the morning.

Rainfall totals since the first round of weekend rain moved in Saturday night ranged from 1.11 inches in Alpharetta, 1.30 inches in Dunwoody and 1.38 inches in Chamblee to 1.63 inches in Marietta, 1.84 inches in Dallas and 2.17 inches at Hartsfield-Jackson International Airport.

A flood warning that had been set to expire at 7 a.m. Monday was canceled earlier in the morning as the rain diminished.

Channel 2 meteorologist Brian Monahan is forecasting mostly sunny skies Tuesday through Thursday before rain moves in again on Friday and into the first weekend of the new year.

Highs will be in the low 60s Monday, mid-50s Tuesday and low 50s Wednesday and Thursday, with morning lows in the mid-40s Tuesday, mid-30s Wednesday and low 30s Thursday.

There’s a 60 percent chance of rain Friday, along with lows in the mid-30s and highs in the mid-50s.
