LAWTON, Okla. (KSWO) - Good morning! We start off the morning with mostly sunny skies, though cloud coverage is expected to build throughout the day, becoming partly-to-mostly cloudy. Despite the cloud coverage, it will be another hot day with most of Texoma getting into the low 100s this afternoon. Heat advisories are in effect for counties east of I-44 until later today. The reason for this heat is: 1) it is still summer, 2) southwesterly winds at 10-15 mph, and 3) pre-frontal warming ahead of a descending cold front. This front will be moving across Northern Oklahoma today, bringing with it showers and storms along and behind it. The front will only make its way as far south at I-40 by the end of the day, and that is where the best chances for rain will be, with northern counties seeing isolated showers and storms in the late afternoon and early evening.
