The episode as NWS CRP wrote it up.
A weak upper level disturbance interacted with deep moisture along the coast to produce scattered thunderstorms during the morning of June 1st. The storms trained across the downtown area of Corpus Christi. Roads became impassable with numerous cars stranded in high water.
The local office's own words before the first event, 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 the first event at Jun 1, 5:34 AM CST, 4 hours 3 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Corpus Christi TX 634 AM CDT Thu Jun 1 2017 .DISCUSSION...See Aviation section for 12Z TAFs. && .AVIATION...Satellite imagery shows a band of MVFR ceilings from the inland portions of the Coastal Bend into the Brush Country with a band of LIFR ceilings and MVFR-IFR vsbys in fog near Cotulla. Expect MVFR ceilings will remain over this region and move into portions of the coastal plains through 15-16Z. Scattered showers continue to develop in convergence zone along the coast early this morning. The showers will move to the north. This activity will move slowly inland with the low level convergence zone through the morning hours into early afternoon. Thunderstorms may become embedded in this shower activity later this morning into the afternoon. MVFR ceilings and vsbys will be possible with the scattered convection. Drier air will move into the region by this evening. VFR conditions are expected from mid to late afternoon through the evening. MVFR ceilings could move back into the coastal areas by 08Z Friday. && .PREVIOUS DISCUSSION... /Issued 407 AM CDT Thu Jun 1 2017/ SHORT TERM (Today through Friday)... Satellite imagery shows the mid level short wave trough from northwest Texas to the Mid-Coast region with drier air in the mid levels over much of South Texas. But adequate moisture remains in the lower levels. MSAS analysis shows coastal convergence zone and isolated convection has formed in this area in the past couple of hours. This axis of higher low level moisture and region of convergence will slowly move inland through the day. Will show highest PoPs/likely over the Victoria Crossroads with chance PoPs elsewhere except only slight chance far west. Weak mid level ridge along with area of drier air will move into the area tonight. Expect a dry evening, then isolated showers that form over the Gulf could move into the coastal counties overnight. NAM and GFS indicate a weak mid level short wave trough could move out of Mexico into the Brush Country on Friday. Moisture levels will be marginally adequate for isolated to possibly scattered convection to develop by late morning and continue into the afternoon. LONG TERM (Friday Night through Wednesday)... Friday Night should generally be dry over land as significant deep layer moisture should be lacking. An isolated shower may occur by late in the night across the offshore Gulf waters where deeper moisture is prog to be lurking to the east of a weak coastal trough. Moisture depth is then prog to slightly increase areawide during the day Saturday as the coastal trough nudges inland and as a seabreeze pushes inland in the afternoon. Result should be isolated to perhaps scattered diurnally driven convection across the inland Coastal Plains in the afternoon...with slightly better areal coverage being confined to the Victoria area. Forecast confidence then quickly declines for the rest of the forecast period. EPAC Tropical Depression 2...currently located off the coast of southern MX is prog to move inland over southern/southeastern MX and dissipate late this week. The GFS and ECMWF both want to bring the mid level vort max of TD2 over the Gulf of Mexico along with deep tropical moisture. Both guidance suites...and associated ensemble means...vary regarding where potential surface troughs and/or broad areas of low pressure may then develop across the W/SW Gulf as well as where the best tropical moisture will be advected. GFS wants to keep the deepest moisture E/SE of the region until late Mon while the ECMWF sets up a nice ESE fetch of deep moisture into S TX beginning late Saturday. Result is ECMWF being significantly wetter than the GFS for Sunday through Monday morning. For now...the forecast for Sunday indicates there should diurnally driven isolated convection across portions of the area as a seabreeze tries to push inland and as outer effects of a strong s/w trough/quasi-closed low over SW TX affects the area. This mid level trough/low is then prog to slowly dig south across the region bringing enhanced chances of convection through the first half of next work week. QPF amounts and how high/low precip chances ultimately end up being next week will be dependent upon amount of moisture depth/magnitude that materializes. Have continued with seasonably warm/humid conditions through the forecast period...though have undercut MEX guidance by a couple of degrees for max temps for early next week given currently expected chances of precip. && .PRELIMINARY POINT TEMPS/POPS...
