Area Forecast Discussion National Weather Service Corpus Christi TX 623 AM CDT Mon Jun 1 2020 .DISCUSSION... Updated for 12Z Aviation discussion. && .AVIATION... Convection has begun to increase this morning. CRP, ALI, and COT are are expected to have predominately MVFR ceilings and IFR expected as showers and storms move inland and across the terminal sites. LRD and VCT still remain VFR,though conditions will deteriorate to MVFR through the morning and IFR with any storms. Timing of MVFR to IFR transitions will be challenging, so have introduced TEMPO groups for time periods when storms are expected. Rain and thunderstorms will continue through the evening tonight, before beginning to wane by the end of the forecast period. && .PREV DISCUSSION... /Issued 355 AM CDT Mon Jun 1 2020/ SHORT TERM (Today through Tuesday)... Convection is expected to redevelop this morning along a coastal trough in place along the coast. Models indicate this may move a bit more inland today, which will increase the chances for heavier precipitation over the Coastal Bend. Convection will move inland through the day, increasing chances for showers and thunderstorms across the Brush Country. Localized flash flooding may be possible today in some of the heavier showers, but widespread flash flooding continues to be unlikely. Convection will begin to decrease tonight and into Tuesday. Temperatures today will be several degrees below normal with rainfall and thick cloud cover expected, with highs in the low to mid 80s. Tuesday will see slightly warmer temperatures, with highs in the mid to upper 90s as rain chances diminish and clouds begin to clear. LONG TERM (Tuesday Night through Monday)... The upper level low that has been influencing the region will slide east as the upper level ridge builds in. Meanwhile, onshore flow in the lower levels will continue to usher moisture inland. Models have backed off from keeping PWATs around 2" through the week and are now generally around 1" which is still above average for early June. Kept POPs higher on Wednesday as the subtropical jet will linger around and provide sufficient lift for additional showers and storms. With relatively high moisture but no significant forcing to close out the work week, would expect any convection to be mainly diurnally/sea breeze driven. Temperatures will warm up throughout the week with highs in the upper 80s along the immediate coast to the upper 90s out west. Lows will be seasonal with temps dropping in the low to mid 70s across the Brush Country to around 80 along the coast. The forecast heading into the weekend remains uncertain. The National Hurricane Center continues to monitor the remnants of Tropical Storm Amanda which are currently located near the Guatemala- Yucatan border. The system is forecast to move into the Bay of Campeche over the next several days. The NHC currently has a 70% chance of formation over the next 5 days as the system may redevelop in a favorable environment. The last item of concern is the potential for coastal flooding by mid week. The combination of a low pressure system developing to our south and a high pressure well to our east will provide an easterly fetch across the Gulf which may result in water piling up along Gulf- facing beaches, especially during high tide. Recent P-ETSS and E-TSS output show tidal levels exceeding 2 ft MSL on Wednesday and Thursday. MARINE... Showers and thunderstorms will continue today across the area. Light to moderate easterly winds are expected but gusty winds are possible in and around thunderstorms. Weak to moderate easterly to southeasterly flow is expected through the period. Isolated to scattered showers and thunderstorms are possible through Wednesday evening. Showers and storms will become more isolated to close out the work week. There remains a bit of uncertainty with the forecast over the weekend with regards to the formation of a potential tropical system in the Bay of Campeche. The National Hurricane Center currently has a 70% chance of formation over the next 5 days. && .PRELIMINARY POINT TEMPS/POPS...
