Nowcast for Oklahoma/A Freeze for Some Parts of Northern Oklahoma

Early this evening…deep low pressure was centered over Missouri…moving slowly east. Around the low…a large area of exceptionally strong winds blanketed Kansas…Oklahoma…and parts of Texas. Until sunset…winds in western Oklahoma and western North Texas…will average 30 to 40 mph…with gusts of 50 to 60 mph. Winds in central and southern Oklahoma will average 25 to 35 mph…with gusts up to 50 mph. Southeast Oklahoma will see winds of 20…gusting to 35 mph. Sunset occurs around 8 PM today. The vertical mixing of the atmosphere will weaken substantially at that time…and the severe gust speeds will disappear. Still…strong winds gusting over 40 mph…will continue for at least 2 or 3 hours after sunset… especially northeast of a line from Woodward to Lawton to Marietta. A small ridge of high pressure will attempt to build into the region from west to east overnight. Decreasing wind speeds combined with cool and dry air…will lead to a light freeze late tonight. People with need to protect sensitive vegetation…especially west of a line from Stillwater to Oklahoma City…Duncan…and Wichita Falls.
