LAWTON, Oklahoma (KSWO) –

For tonight, increasing clouds and slow cooling with night lows falling in the low 60s. The wind blows at a speed of 10-15 miles per hour from the south with gusts of up to 20 miles per hour.

Mostly sunny and hot on Saturday with highs in the mid to mid 90s, which is 15-20 degrees above the average for this time of year. Considering low relative humidity of only 15% and winds from the south of 15-20 mph with higher gusts of wind, this will lead to increased fire weather conditions on Texoma. Fires that develop could spread quickly and be difficult to contain.

An approaching storm system on the upper level on Sunday will increase the likelihood of showers and storms in the early evening hours. There are currently signs that the storm system may slow down, which will increase the risk of severe weather further west, which will encompass more of Texoma. A QLCS (Quasi-Linear Convective System) will develop along and in front of the cold front and a dry line. As storms develop, they are expected to gradually intensify as they move east and toward I-44 and I-35. In this gust line, one or two embedded weak tornadoes cannot be ruled out and can form very quickly with little to no warning. The main threats in Texoma east of the Mangum-Seymour Line will be noxious gusts of wind up to 70 miles per hour and hail the size of golf balls and local flooding.

The front will be far east of Texoma at sunrise on Monday morning and plenty of sunshine will return. On Tuesday morning, due to the isentropic upwelling, especially in areas along and south of the Red River, some showers and storms could develop. This will be ahead of the # 2 storm system that poses the threat to all types of severe weather. The timing is currently uncertain as storms could break out at any time between Tuesday evening and early Wednesday morning. With this system, more energy will be available, which brings a good chance of scattered to numerous strong and severe thunderstorms. During this period there will also be more wind shear, which means a slightly higher chance of tornadoes for Texoma. We’ll have more details on Storm System # 2 in the next few days.
