The coldest temperatures of the season are predicted throughout Oklahoma early this week.
The National Weather Service has issued a hard freeze warning beginning 8 p.m. Tuesday until 10 a.m. Wednesday for nearly all of Oklahoma. A strong cold front is moving across the state Monday, making a few thunderstorms possible. Much colder temperatures are expected after the front leaves the state.
No severe weather is expected Monday, but forecasters say freezing drizzle is a possibility in the Oklahoma Panhandle.
On Tuesday, high temperatures are expected to remain in the 40s. Forecasters say low temperatures of 20 degrees to 25 degrees are expected early Wednesday.
