WebDec 6, 2024 · Drybar The Double Shot Blow-Dryer Brush. Drybar’s hair-dryer brush is phenomenal because it is delicate on all hair types, making it perfect for fine or damaged hair. This hair-dryer brush has three heat settings, and its highest temperature is a bit lower than most (167 degrees, to be exact). WebThese “pop-up” type storms will move from southeast to northwest, reverse of what we’re used to. Highs will be in the 70s Friday. The scattered storm chance will die down Friday night as temperatures only drop into the mid to upper 50s by Saturday morning. Saturday’s forecast continues to trend drier as our weekend rainmaker slows down.
