Overnight, under clear skies, look for temperatures to fall to their coldest readings since last January. Some of us will experience single digit overnight lows. Any wind at all will result in wind chill values easily as low as 5 degrees.
We wrap up the work and school week with southerly winds returning at lots of sunshine. This can often mean a big jump in the temperature between the morning low and afternoon high. So tomorrow, highs will race into the upper 30s to around 40-degrees for some of us.
Southerly winds continue for much of Saturday. At the same time, clouds will increase Saturday and by Sunday morning a weak storm will pass to the north of Tulsa. This storm will draw warmer air into the region, so on Sunday its possible southern parts of Green Country could hit 60 for a high.
Already looking at another round of cold air that is scheduled to arrive in the middle of next week.
Tonight: Clear and cold. Morning Low: 15° colder north Wind: Light NNE
