Area Forecast Discussion National Weather Service Fort Worth TX 315 PM CDT Sun Jul 23 2017 .DISCUSSION... Abundant moisture and moderate instability will remain in place across the region tonight through Monday and continue to be the key ingredients for scattered showers and thunderstorms. Convection late this afternoon into the evening hours will remain most likely on either side of a weak shear axis (as seen on current water vapor images) which roughly bisects the region from northeast to southwest. Any outflow from these storms will likely initiate new convection which could linger through the evening hours. These storms will have the potential to briefly become strong/severe with downburst winds the primary hazard. Slow movement and high precipitable water values will also yield locally heavy rainfall in those areas fortunate enough to see storms. The focus for convection this evening into the overnight hours will be along a very weak cold front currently moving across Central Oklahoma. Models have been fairly consistent developing at least some convection across southern Oklahoma along this front with some weak organization expected through the night. Although we don't anticipate a strong MCS moving south of the Red River overnight/Monday morning, there should be at least scattered showers and storms with the best chances across the north and northeast zones. The activity that develops Monday afternoon will be largely dependent on what happens during the morning hours. The most likely scenario, and the one we will base this forecast on, is that morning convection across the northern zones will send out multiple outflows which will become the focus for afternoon and early evening convection with the best storm chances across the southeast quarter of the forecast area. Storms should dissipate late Monday evening with the loss of surface heating and increasing large scale subsidence. Monday should be slightly cooler than today due to increasing cloudiness and slightly higher storm coverage. Although it will still be hot with high temperatures in the 90s, heat index values will be below heat advisory criteria. Therefore, we will let the current heat advisory expire at 7 PM tonight. By Tuesday the upper ridge will build back over the Central and Southern Plains and result in an increase in temperatures and a decrease in rain chances. This pattern will continue on Wednesday and Thursday with triple digit heat and heat index values in excess of 105 returning to many locations. The good news is that the upper ridge is progged to shift back to the west by the weekend which will result in a weak frontal passage Saturday, increasing rain/storm chances and slightly cooler temperatures. 79 && .AVIATION... /Issued 1245 PM CDT Sun Jul 23 2017/ The upper ridge currently anchored out west is being weakened on its eastern flank by an upper low over Southern Louisiana, and a shortwave trough dropping southeast through the Southern Plains. This vulnerability will last through Monday, leading to multiple opportunities for convection over the next 24 to 36 hours. The 1.73 inch PWAT value on the morning sounding indicate that the atmosphere has moistened considerably over the past 24 hours. With isolated storms still ongoing around the region, the feeling is that coverage will increase considerably after a few more hours of surface heating and temperatures approach upper 90s. Due to the expected scattered nature of the convection, VCTS will have to suffice in area TAFs for the time being. If it becomes apparent that storms will affect a particular airport, an amendment for TEMPO TS will be done asap. Activity should decrease in coverage this evening as surface heating wanes. There is some indication that a loosely organized MCS will develop over the Southern Plains in association with the shortwave trough, and approach from the north during the overnight hours. Storms would likely weaken as they approached, so have stuck with VCSH tor the Monday morning hours. VCTS has been added to the extended DFW TAF for anticipation of another round of scattered convection Monday afternoon. 30 && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
