The potential for record-breaking temperatures will end on Saturday.
Strong north winds are expected behind a cold front on Sunday producing sustained wind speeds at 20-30 mph with gusts at 30-40 mph across most of our area. Southwest Oklahoma could see gusts as high as 50 mph. Windy conditions will persist through much of the daylight hours into the evening then weakening a bit during the overnight hours.
There is a 20% chance for precipitation on Sunday in association with a strong cold front passage. Most of the precipitation across our area would be rain but some of that across northwest Oklahoma could transition to a few flurries late Sunday afternoon and evening. Southeast Oklahoma could also see a few weak thunderstorms by late afternoon.
Dry cold air will be surging in behind a strong cold front on Sunday with gusty north winds producing strong wind chill values felt by sundown with overnight wind chill values in the teens. Cold air will persist into Monday.
At least elevated fire weather conditions are expected behind a cold front on Sunday and Monday due to gusty north winds and incoming dry air/lower humidity.
Unseasonably warm through Saturday then cooler & windy on Sunday behind a strong cold front passage. Low chances for mostly rain across on area on Sunday although rain to transition to a snow mix across northwest Oklahoma ending with flurries during the evening. Cooler starting early next week with a warming trend and more seasonably normal temperatures going mid-week into New Years Day.

Local Weather History For December 27th...
A small but intense band of snow spread accumulating snows up and
down the Interstate-44 corridor on this date in 2014. The snow band
was nearly stationary for much of the morning, resulting in localized
4 to 6 inch snow totals from Chickasha and Lawton down to Seymour,
TX. Once the snow ended, Oklahoma City measured 3.5 inches of
storm-total snow, a new record for December 27th. The old record of
1.3 inches from 1968 was smashed! In addition, snow had never fallen
on December 27th in Wichita Falls, so the 2 inches of snow that fell
became the new daily snowfall record.
