From News9 Meteorologist Stephanie Malone...
Temperatures outside this afternoon will feel pleasant compared to the colder temperatures this morning, with highs expected in the mid 40s today under sunny skies. Lows tonight will dip down into the mid 20s before rebounding once again tomorrow afternoon into the mid 50s.
Wednesday night is when the arctic air makes its entrance into Oklahoma. Lows Wednesday night will plummet down into the teens, and only get up to the mid 20s throughout Thursday. Thursday evening will be another teeth chattering night with lows getting into the low teens, and then highs in the upper 30s on Friday.
