NWS Lubbock, TX wrote its last area forecast discussion before the first event at Aug 5, 3:20 PM CST, 2 hours earlier.
Area Forecast Discussion National Weather Service Lubbock TX 420 PM CDT Sat Aug 5 2017 .AVIATION... Updated TAF for KCDS to add mention of thunderstorms through 00Z following current convective trends. Short term models also indicated area of enhanced cumulus field currently in the western South Plains along an axis from Hart to Littlefield to Plains may continue to develop into showers and Thunderstorms. If this does happen in the next hour or two, will be adding mention of thunder and gusty winds to TAFs at KPVW and KLBB. Lipe. && .PREV DISCUSSION... /issued 345 PM CDT Sat Aug 5 2017/ DISCUSSION... After the recent cool stretch to conclude July and start August temperatures were now heating back up toward more typical values. 20Z temperatures were mostly in the 90s with even a couple of triple digits noted off the Caprock. This heat along with weak convergence and a residual mid-level cloud deck have proved enough to generate isolated convection across the Rolling Plains. This activity should shift east of the CWA by 00Z, but additional storms developing over the higher terrain of New Mexico into the northwest Texas Panhandle within a surface trough will also move eastward into and across at least the northern and western zones, and potentially much of the CWA tonight. A MCS may even try and form, though the best prospects for this will be across the Panhandle into western Oklahoma, perhaps clipping our northeast corner. A weak cold front is still on schedule to drop into the South Plains during the day Sunday. Ahead of the front temperatures should soar well into the 90s, with a few triple digits again possible in the Rolling Plains, while highs likely top out in the 80s over the northwest zones where the front moves through earlier in the day. This front will also provide a focus for storm development by mid- late afternoon, with locations along and east of the edge of the Caprock initially favored. Instability levels should be up somewhat from recent days and could support a few strong to marginally severe storms. We will then have to watch and see if additional convection can develop locally (further westward) as a moist 30+ knot southerly LLJ cranks up and impinges on the frontal zone. Lastly, storms originating over northeast New Mexico may slowly edge toward the region. Given slow storm motions, well above average PWATs and the potential for training cells, locally heavy rainfall will be a concern. Given this we have inserted a locally heavy rainfall mention in the grids Sunday night into Monday. The lingering frontal zone, deep moisture and weak westerly to northwesterly flow aloft will keep storm chances going through the first part of next week, though details remain elusive and will likely be driven by mesoscale influences. Some guidance suggests there may be a relative lull in precipitation locally by Monday night into Tuesday, though signals are mixed enough to keep slight chance to low chance PoPs going. A southwestern ridge may then attempt to build eastward into Texas by the middle of the week and this could tend to warm things back up (after highs only in the 70s and 80s Monday and Tuesday) as well as shift the more favorable storm chances to our north. That said, the fringe of west-northwesterly flow aloft may still be close enough to keep a risk of thunderstorms occasionally skirting the northern/northeastern zones. Eventually a deeper trough/low digging into the Midwest may propel another cold front southward into the region while buckling the flow to northwesterly again by next weekend. If this happens cooler temperatures and increasing thunderstorm chances would again visit the region. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && 05/05/04

Wind gusts to 60 mph will be the main severe weather threat, mainly to the north of a Dimmitt to Paducah line. .DAYS TWO THROUGH SEVEN...Sunday through Friday Thunderstorms are expected to become more numerous Sunday afternoon and evening, with good storm chances continuing into early next week. The greatest threat with this activity will be locally heavy rainfall though a few strong storms will also be possible. .SPOTTER INFORMATION STATEMENT... Spotter activation is unlikely to be needed this afternoon and tonight.
