Metro Atlanta's 42-day, record-breaking streak without rain is about to end.

After days of rain chances that failed to produce any showers, the metro area could get heavy downpours early Tuesday, Channel 2 Action News reported.

There is a 20 percent chance of rain Monday, a 90 percent chance Tuesday and a 100 percent chance Wednesday, the television station reported.

The rain was about 245 miles west of Atlanta just before 7:40 a.m. That system could dump up to 2 inches of rain in parts of metro Atlanta by noon Tuesday and up to 4 inches of rain by Wednesday.

Parts of northwest Georgia will get the first round of heavy showers by 10 p.m. Then, they will move eastward.

By 3 a.m. Tuesday, a diagonal line of heavy downpours will stretch from LaGrange to Atlanta and Blairsville.

“I am concerned about the possibility of downed trees and power outages,” Channel 2 meteorologist Brian Monahan said.

That won’t be a concern Monday, which is expected to be dry. Temperatures were 47 degrees in Atlanta, 46 in Blairsville and 46 in Griffin just before 7:40 a.m. Temps will reach the 60s and wind gusts will reach 25 mph by 2 p.m. in metro areas, Monahan said.

A high wind warning went into effect just after 3:30 a.m. Monday for Dade, Walker and Lumpkin counties. That means those areas could get sustained winds of at least 35 mph and gusts of at least 50 mph. The warning, which does not extend to metro Atlanta, is set to expire at 7 a.m. Tuesday.
