Area forecast discussion, Jun 23, 11:58 AM CST, 1 hour 52 minutes before
Area Forecast Discussion National Weather Service Norman OK 1258 PM CDT THU JUN 23 2016 .DISCUSSION... The 23/18Z TAF discussion is below. && .AVIATION... VFR conditions are expected to continue through the TAF period. Isolated showers and storms may impact KGAG/KWWR/KPNC this afternoon, but the probability of storms is too low to include in TAFS. A windshift and/or outflow boundary will be in the vicinity of KGAG and KWWR through this afternoon, which will result in variable wind direction. Elsewhere, expect south-southwest winds to weaken and back to the south-southeast overnight. There is an outside possibility for storms to approach KGAG and KWWR from the northwest overnight; however, confidence is low. Mahale && .PREV DISCUSSION... /issued 1030 AM CDT THU JUN 23 2016/ DISCUSSION... Precipitation continues to struggle to move into our forecast area from the Panhandles. The mid/upper-level disturbance over southwest Kansas is, however, producing strong storms near Dodge City. This type of convection may spread back south into northern Oklahoma by mid-afternoon, and persist into the early evening, as suggested by the HRRR/HRRRX. This is handled well by the current forecast, so no changes are planned for this morning. PREV DISCUSSION... /issued 455 AM CDT THU JUN 23 2016/ DISCUSSION... Convection over the Texas panhandle has been on a decreasing trend recently, so despite earlier HRRR runs forecasting it to move into northwest Oklahoma, that is looking less likely. Still there is a chance of redevelopment this afternoon in northern Oklahoma near the surface boundary. Low storm chances will be confined to the north tonight and Friday as well. We have a fighting chance for storms over a broader area this weekend and into next week. Otherwise, very warm conditions will continue. && .PRELIMINARY POINT TEMPS/POPS...
