Large hail, damaging winds and tornadoes will all be possible in the Ozarks Friday afternoon and evening.
The National Weather Service says how bad things get will depend on how much instability develops.
With enough instability, supercell thunderstorms capable or producing all modes of severe weather will be possible.
If the instability stays weaker, severe storms will still be possible, but the overall threat will be lower.
Forecasters say the greatest risk for severe thunderstorms will be along and west of an Osceola to Marshfield to Gainesville line.
The weather will turn cold once again, with another freeze possible Saturday night and again Sunday night.
