The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Midland/Odessa, TX wrote its last area forecast discussion before this special weather statement went out at May 29, 6:34 PM CDT, 48 minutes earlier.
Area forecast discussion, May 29, 6:34 PM CDT, 48 minutes before
Area Forecast Discussion National Weather Service Midland/Odessa TX 634 PM CDT Mon May 29 2017 .DISCUSSION... && .AVIATION... A low chance of storms tonight south of the Pecos river... have not included them in FST or PEQ TAFs but may have to add. Otherwise gusty E wind should decrease after sunset. Could see some morning stratus with MVFR cigs at MAF and to a lesser extent FST. && .PREV DISCUSSION... /issued 209 PM CDT Mon May 29 2017/ DISCUSSION... A few strong to severe thunderstorms this afternoon, tonight and Tuesday will transition to more of a heavy rainfall threat Tuesday into Wednesday, as a weak shortwave trough tonight/Tuesday is followed by a stronger shortwave trough, and the actual upper trough, Tuesday night/Wednesday. After near normal high temperatures today, it appears highs will decrease the next couple of days, and bottom out Wednesday when rain chances will likely be best. Heating of the higher terrain should be sufficient for widely scattered thunderstorms this afternoon, mainly along and south of Interstate 10 where the best instability resides. A couple of storms could produce hail, strong winds and brief heavy rainfall due to SBCape rising to at least 1500-2000 J/Kg, and mid level shear and lapse rates increasing/steepening to 35kt/7.5C/Km respectively. A weak shortwave trough could aid convection developing off the higher terrain over Chihuahua, which will then spread eastward perhaps into western portions of the forecast area late tonight. Just how much convection makes it into the forecast area will determine how everything unfolds during the day Tuesday, as the mentioned shortwave trough gradually traverses the area. Will continue to carry the chance of thunderstorms already going in the forecast tonight and Tuesday, with maybe slight adjustments. As briefly mentioned initially in this discussion above, a more significant shortwave trough/ua trough is expected to impinge upon the region Tuesday night and Wednesday. The threat of severe storms will likely decrease due to less instability from less heating from precipitation and cloud cover, and weaker shear. But, the threat for heavy rainfall and flash flooding will increase due to PWats increasing to 1-2 S.D. above normal and weak flow contributing to slow thunderstorm movement, possible training. Although temperatures will be 5-10 degrees below normal Wednesday afternoon, there will be plenty of instability to fuel heavy rainfall producing thunderstorms. The timing of all this will be dicey though since widespread convection late Tuesday night/ Wednesday morning would definitely alter when, where, and if heavy rainfall would occur Wednesday afternoon/night. Despite this uncertainty, will still carry hefty Pops for these periods. Will not issue a Flash Flood Watch at this time, but one could be forthcoming within the next 24 hours, especially concerning Wednesday, although a Watch could easily end up being in effect for Tuesday too. Model differences accumulate Thursday and after, so we could see a drying and warming trend under an expanding upper ridge, or a continuation of wet and near to below temps. Will tend between the two different scenarios, although moist ground and warm to hot temperatures could yield more convection, especially Thursday. && .PRELIMINARY POINT TEMPS/POPS...
