NWS Corpus Christi, TX wrote its last area forecast discussion before the first event at Apr 30, 11:14 PM CST, 46 minutes earlier.
Area Forecast Discussion National Weather Service Corpus Christi TX 1214 AM CDT Fri May 1 2020 .DISCUSSION... See aviation discussion below for the 06Z TAFs. && .AVIATION... VFR conditions are expected through the TAF period, although MVFR visibility may develop briefly across the VCT TAF site early Fri morning. FEW/SCT clouds will develop through Fri afternoon and evening. Light winds through Fri morning will become southeasterly and gusty by Fri afternoon. Gust to around 25kt will be possible. Winds then diminish through Friday evening. && .PREV DISCUSSION... /Issued 627 PM CDT Thu Apr 30 2020/ DISCUSSION... Updated for the 00Z Aviation Discussion. AVIATION... With the exception of a brief period of MVFR VSBYs toward VCT between 11Z-13Z FRI, expect VFR conditions through the period. Few low level clouds to develop FRI as moisture gradually increases. General E-SE wind this evening to become light and variable overnight. SE winds to strengthen FRI late morning/afternoon with gusts of 20-25 KTs possible. PREV DISCUSSION... /Issued 400 PM CDT Thu Apr 30 2020/ SHORT TERM (Tonight through Friday night)... An approximately zonal upper pattern is expected during the period (per deterministic output), and result in deepening surface low pressure over the Lee of Rockies/SRN Plains Friday/Friday night. As a result, increasing onshore flow is expected Friday/Friday night. The NAM/GFS predict PWAT values below normal tonight, followed by a gradual increase with magnitudes approaching normal Friday night. The NAM deterministic predicts a thermodynamic profile conducive to brief radiation fog over portions of the Victoria Crossroads around 12z Friday. Decided to place patchy fog in the grids for the NERN CWA 10-12z Friday period. Most recent surface dew points/general dry conditions/clear skies suggest temperatures tonight well below the NBM. However, will only fcst slightly below the NBM. LONG TERM (Saturday through Thursday)... Medium range models are consistent in building a broad ridge over northern Mexico, with warm subsident flow over South Texas. Rain chances are minimal through the extended period. Temperatures will gradually warm through the period, with air temperatures well into triple digits expected on the Rio Grande Plains by early next week. Heat indicies are expected to be near 105 for Monday and Tuesday. Models are not so consistent on the potential for a weak boundary to move through the region toward the end of the extended period. For now will go closer to NBM guidance, which shows cooler temperatures Wednesday and Thursday. If the front doesn't make it this far south, high temperatures for Wednesday and Thursday may end up closer to Tuesday's readings. MARINE... In response to deepening low pressure over the SRN Plains, expected onshore flow to increase Friday. The Small Craft Exercise Caution condition may occur Friday afternoon/night over the Coastal Waters. A moderate onshore flow will continue into early next week. Normal fluctuations may periodically raise flow enough for small craft to execise additional caution. && .PRELIMINARY POINT TEMPS/POPS...
