Clear skies, dry air, and light winds have brought very cold weather to northern Oklahoma early Friday morning.
This will be the coldest morning of the late fall and early winter season for many locations, with temperatures in the upper teens and lower 20s.
A surface high-pressure system is located to the north and east, allowing for a light north wind Friday morning. Later, as the ridge moves, a light south wind will develop at 10 mph.
This will result in mostly sunshine and afternoon highs reaching the upper 40s and lower 50s.
Most of the weekend will be pleasant yet with some increasing cloud cover with temperatures in the upper 50s and lower 60s. There will be a chance for a few showers across southern Oklahoma and North Texas.
A low-pressure system has been cut off from the upper airflow for the last several days, positioned across the desert southwest. It is slowly moving eastward and will eject over the central and southern Plains on Sunday.
"Another lobe of energy will arrive at the base of this trough later Friday night," producing showers and storms across Texas that will extend into the Red River Valley Saturday morning and then again late Saturday night and Sunday morning."
There will be a low-end probability for a few showers along and south of the I-40 corridor, but higher chances will be along the Red River Valley.
"Early Sunday morning, as the cutoff low begins to eject to the east-northeast," additional showers and storms are likely to occur across northeast Texas, extending into far southern Oklahoma."
A few showers will be possible along and east of Highway 69 across east-central sections of the state, but higher probabilities will remain to the south and east of most of our area.
"As the low ejects away from state on Monday," a cold front is expected to move across by midday bringing falling temperatures from 50s into 40s by afternoon."
- Tuesday: Morning starts in upper 20s/lower 30s; afternoon highs mid/upper 40s
