Area Forecast Discussion National Weather Service Lubbock TX 417 PM CDT Mon Aug 21 2017 .DISCUSSION... Small disturbance, best seen on visible imagery this afternoon southwest of Lubbock, helping to focus scattered showers and storms across the central South Plains into the Permian Basin. This area is expected to lift northeast this evening so have carried chance POPs into much of the Rolling Plains. Plume of high precipitable water air continues to stream north across west Texas into western Oklahoma. This will likely support some renewed growth overnight associated with a strengthening low level jet and more shortwave energy streaming out of northern New Mexico. Upper level flow quickly transitions to northwest on Tuesday as ridge axis begins to amplify across the desert southwest. This pattern will be favorable for upscale growth of convection across the southern Rockies into a forward propagating MCS overnight. Have increased pops to likely category across the northwest South Plains and southwest Panhandle as a result but these could easily be extended further east for the remainder of the area as a frontal boundary also gets into the mix. Greater uncertainty in the rain forecast begins on Wednesday with the potential for the frontal forcing to be driven further south by convective outflow than model projections indicate. The upper flow also weakens during this time and veers to the north/northeast as the midlevel ridge axis briefly builds across the area. Have therefore backed off on POPs north and east late Wednesday into Thursday. Continued easterly upslope flow though should limit daytime heating with a good mix of clouds and sun. With the typically high quantity of low level moisture still in place late in the week and another shortwave trough lifting across the High Plains chose to accept the blended chance POPs Friday into Saturday. We will have to also keep a close eye on any influence the remnants of tropical storm Harvey will have over the weekend as it moves north into central Texas. && .LUB WATCHES/WARNINGS/ADVISORIES...
