930 AM Nowcast for Oklahoma City/Dryline Update 1

This morning a broad and deep upper level trough was moving eastward…dragging a dryline through Oklahoma and North Texas. At 9 am…the dryline extended from Medford to Weatherford and Frederick Oklahoma…to Benjamin Texas. Ahead of the dryline…a few stray rain showers will develop at times…but they will produce very little rain. The main weather story will be strong and gusty winds developing later this morning. It was already breezy…with winds of 15 to 25 mph throughout the region. High clouds may temporarily delay the onset of stronger winds…but by early afternoon…the clouds will begin to move out…and deep vertical mixing will bring strong wind speeds from aloft…to the ground. By 1pm…the dryline will reach Stillwater to Norman to Henrietta Texas. West to southwest winds will increase to sustained 25 to 30 mph…with gusts over 45 mph. In northwest Oklahoma…winds are forecast to reach sustained speeds over 35 mph with gusts over 50 mph. With temperatures ranging from the mid 70s to mid 80s this afternoon…and humidity of 10 to 20 percent…people need to be extremely careful to prevent fires from starting. The gusty winds will also create areas of blowing dust…and make travel or outdoor activities difficult.
