What forecasters said that day
The local office's own words before this flash flood watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Corpus Christi, TX wrote its last area forecast discussion before this flash flood watch went out at May 17, 11:49 PM CDT, 3 hours 31 minutes earlier.
Area forecast discussion, May 17, 11:49 PM CDT, 3 hours 31 minutes before
Area Forecast Discussion National Weather Service Corpus Christi TX 1149 PM CDT Mon May 17 2021 .AVIATION... Conditions are running the gambit across South Texas, with IFR to VFR conditions. Low ceilings across the Coastal Plains are leading to periods of IFR conditions, the Victoria Crossroads will have ceilings bounce between MVFR and VFR, and the Brush Country will continue with periods of IFR to VFR conditions. These conditions are expected to continue through the period. Ongoing convection across the Brush Country will continue to push east across the CWA, hopefully weakening as it does so. Regardless, thunder is mentioned in all TAFs, with earliest arrival times across the west and latest end times across the east. Precipitationwill be quite heavy in these storms, with frequent lightning, gusty winds, and the potential for hail. && .PREV DISCUSSION... /Issued 931 PM CDT Mon May 17 2021/ DISCUSSION... Quick update to raise pops out west where convection looks to persist into the overnight hours. PREV DISCUSSION... /Issued 749 PM CDT Mon May 17 2021/ DISCUSSION... Severe Thunderstorm Watch 184 has been issued for an area that includes Webb and LaSalle counties until 04z. Isolated slow-moving thunderstorms are possible, and some may produce large hail. AVIATION... MVFR and low VFR conditions will become all MVFR overnight with convection possible this evening at KCOT. Otherwise expect conditions to improve Tuesday morning. Southeast surface winds will pick up again by Tuesday afternoon and become gusty. PREV DISCUSSION... /Issued 438 PM CDT Mon May 17 2021/ SHORT TERM (Tonight through Tuesday Night)... Very difficult forecast continues through the short term period. Models are all over the place, and you can probably find one run of one model for every different scenario you could imagine. So the challenge is figuring out the most likely scenario given all the inconsistencies. For tonight, the most likely scenario seems to be convection our of Mexico staying north of...or just into our northern counties. 850-300mb thickness lines are oriented pretty well E-W, and with MCS movement generally along or just to the right of that, would expect the majority of the convection to stay north (and south) of our area given current radar picture and anticipated development locations. Do have slight chance to chance PoPs in northern counties to account for the uncertainty here. If storms do make it, there would be a marginal threat for strong winds and large hail given the favorable environment to the northwest. Given the amount of rain we had over the weekend, there is also a concern for localized flash flooding if these storms move over the same areas that received the heavy rains. Will not issue a flash flood watch at this time given the high uncertainty in tonight's rains. By tomorrow, the deep 500mb closed low will be pushing eastward bringing with it some intense energy and beginning a very active period that will extend into the long term forecast discussion below. For Tuesday have increased PoPs a bit inland with chance PoPs extending through the middle of the forecast area. The key that makes tomorrow different from the rest of the week is that PWATs should be around 1.5 inches across the area, which is only around normal, so expect the rain rates of showers and storms tomorrow to be lower than what we saw over the weekend and what we will see later this week. PWATs will begin sneaking up Tuesday night and could begin seeing hints at the heavy rains to come by that point. High temperatures will be near normal tomorrow, with warm/humid nights. There is still a potential for minor coastal flooding tomorrow around mid-day with high tide, but given today's levels did not make it to 2ft MSL, will hold off on issuing an advy for this. LONG TERM (Wednesday through Monday)... A very wet week is in store for South Texas as the synoptic setup continues to favor a significant rainfall event Wednesday into Thursday. An upper-level trough will shift east into Texas from the Four Corners region during the day Wednesday and bring strong upper level winds along with it. At the 500mb level, a closed low will open into a wave, allowing energy to dive into South Texas during this Wed/Thu time frame. This 500mb trough, along with high pressure to the east will help draw an ample amount of moisture into the region. Southeasterly winds in the lower levels (850 mb to surface) will do the same, creating a deep profile of moist air as this energy at the 500mb digs south into our area. PWAT values will be near 2.0 inches as a deep moisture axis sets up over South Texas. Have maintained 70-80% PoPs for Wednesday morning, increasing to 80- 90% Wednesday afternoon into Thursday. With all of this in place, high rainfall rates as well as high rainfall totals are possible. Rainfall totals through Thursday may reach 6-8 inches for the Victoria Crossroads area with 3-6 inches of rain expected over most of South Texas. Locally higher amounts are possible. A flash flood watch will likely be issued tomorrow for the Wednesday into Thursday period. Latest model guidance for the weekend time frame continues to show a narrow trough over the area that becomes trapped between ridging to the west and to the east. PWAT values increase to 2.0 inches and above through Sunday for much of the area in response to the influx of moisture from this system. Will need to continue to monitor over the coming days to see if the location of this trough/moisture axis shifts, but the Coastal Plains should expect a chance of rainfall for this weekend. Minor coastal flooding is possible at times of high tide through Thursday as tidal levels reach to near 2 feet MSL at Bob Hall Pier and Aransas Pass. MARINE... Generally moderate onshore flow will continue tonight and Tuesday. Conditions may briefly approach small craft advisory levels, but overall should remain at exercise caution. Chances for showers and thunderstorms will return Tuesday and persist through the week as a series of upper level disturbances pass through the area. A few storms could be strong to potentially severe. Moderate to strong onshore flow will lead to periods of Small Craft Exercise Caution and Small Craft Advisory conditions through the week and into the weekend. HYDROLOGY... This past weekends rainfall has primed the area for the potential for significant river flooding going into the latter half of this week. With current rainfall forecasts over South Texas and north over the upstream rivers, we could be looking at widespread river flooding, with some rivers to moderate or major flood stage. This will make for a potential very long duration event as it takes days for water to work its way down some of our rivers...the Nueces in particular. && .PRELIMINARY POINT TEMPS/POPS...
