Friday’s rain should clear out in time for this weekend’s full slate of spring festivals — and give road crews dry conditions for several construction projects around town.

Channel 2 Action News meteorologist Karen Minton is forecasting sunny skies for Saturday and Sunday, along with unseasonably cool temperatures.

Saturday will begin very chilly, Minton said, with morning lows ranging from the mid-30s in the suburbs to around 40 degrees inside the Perimeter. Normal low for the date is 52 degrees.

The normal high for April 20 is 73, but Minton said Saturday’s high will fall about 8 degrees short of that mark. Sunday’s high should again be in the mid-60s after an overnight low in the mid-40s.

Those dry conditions will be welcomed by those headed to such outdoor events as the Atlanta Dogwood Festival at Piedmont Park, the Sweetwater 420 Fest in Candler Park, the Big Shanty Festival in downtown Kennesaw, the Sandy Springs Artsapalooza along Lake Forrest Drive and Dunwoody’s Lemonade Days at Brook Run Park.

The dry weather will also be conducive for road construction, and the state Department of Transportation has several projects going on this weekend that will shut down interstate lanes.

In the Cobb Cloverleaf area, up to three lanes of I-285 in each direction will be closed between Paces and Powers Ferry roads, while the ramp from I-75 southbound to I-285 westbound will be closed all weekend.

Also on the top-end Perimeter, the two left lanes of I-285 eastbound will be closed from Roswell Road to Ashford Dunwoody Road, while two westbound lanes will be shut down from east of Ashford Dunwoody to Riverside Drive.

North of Marietta, police will be pacing traffic, or at times shutting down all lanes, on I-75 in both directions between Ga. 5 and North Marietta Parkway from 7 to 8 a.m. on Saturday.

In Atlanta, up to two lanes of Ga. 400 north and southbound will be closed near Lenox Road.
