A slow, cut-off low will drift northeast through Thursday. This will create a divided state with sunshine and 80s west and clouds, rain and 70s east. OKC will have isolated showers and storms today, tonight and Thursday. Skies clear Thursday night giving way to sunshine Friday. Highs will climb to the mid 80s this weekend. An upper level ridge will build next week, blocking storm development and increasing highs to the 90s!
