11:15 AM Nowcast for Oklahoma City/Dryline Update 2


This morning a dryline…accompanied by a Pacific cold front…continued to sweep eastward through Oklahoma and North Texas. Temperatures will not be as warm as the record breaking readings of the past two days. But highs in the 70s and 80s…along with very low humidity behind the front…will create a dangerous fire weather situation this afternoon. At 11 am…the dryline or frontal boundary were seen on radar and in surface observations…extending from just east of Ponca City…to Guthrie…Bethany…and Duncan Oklahoma…and on toward Wichita Falls Texas. By 1 PM…the boundary will move to near Chandler and Pauls Valley…and will pass through the remainder of western North Texas. Behind the boundary…winds will temporarily turn to the northwest before backing around to westerly. Wind speeds will average 15 to 25 mph with gusts to 35 mph…over a large area. Stronger winds will occur in northwest Oklahoma…with sustained speeds around 30…and gusts over 40 mph. Humidity drops very sharply along the boundary…and the entire area west of the boundary will see humidity of 12 to 20 percent through early afternoon. After an upper level disturbance moves through…high clouds will decrease…and wind speeds will increase further this afternoon. The gusty winds will also create areas of blowing dust…and make travel or outdoor activities difficult.
