A broad area of upper level low pressure continues to move across central Texas, bringing widespread shower activity to much of Texas and parts of Oklahoma. Light to moderate rain showers will continue over the next several hours across parts of Oklahoma, generally from just north of Interstate 40 southward.
Heavier showers and embedded thunder will continue from far southern Oklahoma into western North Texas. This large mass of shower activity will slowly move eastward through tonight and into the day tomorrow, with rain slowly tapering off from northwest to southeast. Rainfall accumulations will generally range from a tenth to a quarter inch, but some areas across western North Texas and into southern Oklahoma may pick up an additional half inch to inch of rain before showers cease.
Locally dense fog is expected to develop this evening and overnight. This combined with continued showers will make for hazardous driving conditions as visibilities may be reduced to a half mile or less at times. Exercise caution if traveling this evening or tonight and prepare for possible ponding of water on roadways and areas of dense fog.
