Most of the day today will be hot and dry with widespread upper 90s to near 100 degree highs. Late in the afternoon, a slow-moving “cold” front will move from Oklahoma panhandle southward toward Clinton, Enid, and Alva by 5pm. An isolated thunderstorm along the front is possible, but rain chances before 7pm are around 10%. Any storm that manages to form could become strong or even severe with wind gusts up to 65mph, large hail, heavy downpours, and frequent lightning.
The main time frame for rain will be tonight through Tuesday morning as thunderstorms spread southward toward I-40, especially east of I-35. Rain chances are 40% for Oklahoma City and 70% for Stillwater and Ponca City. Otherwise, expect lows in the low to mid 70s with a southerly breeze at 10-15mph.
The rest of your Tuesday looks very warm and breezy at times with highs in the low to mid 90s and a southerly breeze at 10-20mph. There’s a 20% chance of afternoon and evening thunderstorms, mainly east of I-35.
The rest of the week will be hot and dry with highs in the mid 90s under mostly sunny skies. Rain chances return to most of Oklahoma by Friday night with a strong cold front arriving over the weekend.
