Clouds and moisture will continue to move in Friday evening along with a light south breeze. With the increasing moisture, we can't rule out drizzle or a couple showers by late evening. Overnight some more showers will likely develop especially south of Oklahoma City with lows only falling into the upper 50's to low 60's south of the front. North of the front across northwestern Oklahoma, lows will fall into the 30's and 40's.
As our storm system arrives on Saturday, rain chances increase through the morning and will eventually slide to the east through the afternoon. Rain chances will be lowest across western and northwestern parts of the state compared to rain likely for southern and eastern parts. Temperatures will remain mild despite plenty of clouds through the day with highs in the 50's and 60's to the south.
By Saturday afternoon, rain chances start to slide off to the east as western and central parts of the state dry out, but stay mild.
On Sunday, the actual cold front will sweep in from the northwest with gusty north winds. Temperatures will remain comfortable in the 50's and 60's under partly cloudy skies.
Temperatures cool down a little early next week into the 50's, but no arctic air will be behind this storm system.
