You may be pushing things... but I'd probably give it a shot...
Although... I'd probably wait a bit if I could.
Around here, established plants die when temps drop into the teens...
And you aren't quite that cold... And seeds? I doubt they would mind... It's not going to keep getting that cold, is it?
