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 Mar 10, 5:54 AM CST, 4 hours 31 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Corpus Christi TX 554 AM CST Fri Mar 10 2017 .DISCUSSION... Updated for the 12Z Aviation Discussion. && .AVIATION... CIGs/VSBYs fluctuating between IFR/MVFR/VFR this morning. Should transition to MVFR mid morning with a bit of heating, in addition to an increase in convection coverage. May see some lifting to VFR although BKN CIGs around 3500 FT will be possible. Increasing instability should also lead to isolated to scattered thunder activity through the day. Winds should generally be out of the east-southeast 10-15 KTs. With loss of heating, activity is expected to wane in the evening roughly after 03Z, with a later timing at LRD. CIGs will again lower overnight but fluctuate yet again between IFR/MVFR/VFR through the night. && .PREVIOUS DISCUSSION... /Issued 430 AM CST Fri Mar 10 2017/ SHORT TERM (Today through Saturday)... Persistent onshore flow at the surface and mid level shortwave moving east overhead today will create scattered to numerous showers and thunderstorms today as PWATs increase to 1.5 to 1.8 inches. Convergence and weak instability will lead to best chances across the south and across the coastal plains today. Rain chances trend lower heading into tonight as the main wave pushes east. Moisture will be slightly less for Saturday however high chance pops to even likely pops will redevelop as another shortwave begins to enter the region. Best chances again across the coastal plains shifting east through the afternoon. Did cool temperatures today with expected cloud coverage and rain cooled atmosphere, especially across the coastal plains into the mid/upper 70s. May not have cooled enough. Temperatures to remain in the 70s for Saturday, especially across eastern zones. LONG TERM (Saturday night through Friday)... Most of the energy from the upper system will be over the eastern areas early (or east of the area), then cold front comes down late Saturday night/early Sunday morning. Still enough moisture around and forcing with the front (along with any remnant upper level support) for at least a slight chance for showers and possible thunder. Some fog also ahead of the front overnight Saturday night/early Sunday morning, but will not mention fog after 12Z Sunday for now. Will have likely POPs over the eastern areas Saturday night and chance POPs west. Rain chances diminish behind the front Sunday morning, with just low chance POPs in the afternoon over the extreme southern portions of the CWA (kept a slight chance showers extreme southern areas and gulfmex). After that, it should be dry next few days and overall not too bad of weather for spring breakers (a few cool mornings early in the week). Upper ridge builds in Monday and amplifies Tuesday. Models start to diverge after that, with ECMWF taking longer to break up the ridge and keeping any weak upper support (s/w in NW flow) to the north while GFS is showing potential for some rain and upper support by Thursday. Not sure which solution will prevail, but enough moisture may be around by Thursday to mention at least a slight chance for daytime showers and thunderstorms (GFS showing good moisture increase). Thus, have rain back in the forecast Thursday and Friday, but just a low chance for now. Could have another front late Friday night. For temperatures, generally went with a cooler guidance for Saturday night and Sunday, then a blend of guidance Sunday night. Day 4 through Day 8 forecast was a blend of WPC guidance (both regular and bias-corrected) along with Superblend, which seemed reasonable given the 2 meter temperatures and return flow timing. && .PRELIMINARY POINT TEMPS/POPS...
