Freeze Watches are up for all of central Oklahoma Monday Night and Tuesday Night. Freeze Warnings for areas north and east of OKC for the same time period! I think the best chance for a light freeze / frost in OKC is Wednesday AM! Prepare to protect the plants!  The reason…a secondary surge of colder, dry air is heading south into Oklahoma next couple of days from Canada!  However, it won’t last long!  Expect a very quick warm up with temps rising into the 70s and 80s by the end of this week!
