NWS Corpus Christi, TX wrote its last area forecast discussion before the first event at Mar 15, 11:45 PM CST, 15 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Corpus Christi TX 1245 AM CDT Fri Mar 16 2018 .DISCUSSION... See .AVIATION discussion for 06Z TAFs. && .AVIATION... As low level jet kicks up, should see an improvement in CIGs with MVFR conditions expected at the terminals by 12Z. Surface trough will move into South Texas today, resulting in more of a southwest wind and diminishing moisture. As a result, will see improved CIGS with VFR conditions by 18Z all but KVCT (by 20Z there). With near surface winds veering, we should not see much if anything in rainfall (perhaps a weak shower early at KCRP or later at KVCT but confidence too low for even a VCSH). Sea-breeze will back winds back to the SE at KCRP and KALI late in the afternoon with more easterly winds at KLRD after 17/00Z. CIGS MVFR or IFR return by the end of the terminal forecast all but KLRD with some BR likely at KVCT as well. && .PREVIOUS DISCUSSION... /Issued 936 PM CDT Thu Mar 15 2018/ DISCUSSION... Made updates to temps and POPs to reflect current trends. Did cool overnight lows for a few locations, but lowest temps should be experienced early in the night, especially across the eastern zones as an increase in moisture through the night should allow temps to warm slightly. Removed 20 POPs but continued wording of light rain as isentropic flow continues to produce light rain/drizzle this evening. Little accumulation, mainly traces if anything, is being reported. PREVIOUS DISCUSSION... /Issued 710 PM CDT Thu Mar 15 2018/ DISCUSSION... Updated for the 00Z Aviation Discussion. AVIATION... Patchy light drizzle across S TX this evening is expected to diminish through the night. MVFR CIGs expected to continue overnight (late tonight for LRD) with possible IFR at times. Weakening SE winds this evening will take on a more S-SW direction overnight. A dry line is expected to approach western areas, mainly affecting LRD, with N-ly winds with CIGs lifting and clearing to VFR. Should see CIGs lift farther east but may continue with BKN around 3500 FT, with further scattering at ALI. With the passage of the sea breeze at ALI-CRP, winds should turn back out of the SE around 21Z. Winds should remain rather S-ly at VCT. With the dry line moving in from the west and the sea breeze from the east, there may be enough convergence for isolated convective activity along the boundaries in the afternoon, although capping may be strong still which would hinder development. At this time, will not include in TAFs as confidence in development and location of development is low. PREVIOUS DISCUSSION... /Issued 313 PM CDT Thu Mar 15 2018/ SHORT TERM (Tonight through Friday Night)... Very weak echoes showing up on radar this afternoon across eastern portions of the CWA. This trend is expected to continue this evening with very light precip shifting more over the NE CWA through the night as the upper level jet swings east across the region. Precip forecast for Fri is a bit tricky. Moisture/PWAT values should be sufficient for precip, especially as the environment destabilizes and the cap weakens. In addition, a dryline will shift east across the CWA, providing low level convergence. Very warm temps are expected across the western CWA as a result of a west to northwest flow and much drier airmass. This should help the sea breeze to develop and push inland, running into the dryline and producing mod to strong convergence. Am expecting these combined features to be enough for iso shra/tsras Fri, but did not go any higher than a 20 pop due to the cap and limited upper support. Models show some drying Fri night in the mid/upper levels resulting in a good environment for fog late fri night. Winds across the waters are expected to strengthen tonight to moderate levels in response to a strengthening low level jet. Winds across the offshore waters may briefly approach advisory levels and will need to be monitored. LONG TERM (Saturday through Thursday)... There will be limited rain chances mainly over the coastal plains into the coastal waters over the weekend. As the upper low moves across the northwest United States this weekend with the upper trough extending southward drifting across the Great Basin into the southern Rockies, a couple of short wave troughs will move out of Mexico into Texas. The first short wave trough will be north of the area as it moves across southwest Texas into north Texas on Saturday. Adequate moisture over the coastal plains could lead to isolated convection. The next short wave trough will kick out into the southern plains more to the south. Could see coverage of convection a little better over the Victoria Crossroads Sunday and will go with low end chance PoPs in this area. The short wave trough moving out of the Rockies Sunday night expected to form into a low over Kansas/Oklahoma Monday morning. This upper low will move to the east while a cold front is expected to slowly push through the area during the day Monday. Will be cooler and drier Tuesday as high pressure builds into the area. Onshore flow will develop by Wednesday as the ridge moves to the east with slow warming trend through Thursday. && .PRELIMINARY POINT TEMPS/POPS...
