288 FXUS64 KCRP 311036 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 536 AM CDT Fri May 31 2024 ...New SHORT TERM, LONG TERM, MARINE... .SHORT TERM... (Today through Saturday) Issued at 534 AM CDT Fri May 31 2024 Key Messages: -Low to medium chance for strong to severe thunderstorms today and Saturday -Heat Advisory in effect from 1 PM through 7 PM for portions of the Coastal Bend and Brush Country are expected A cluster of thunderstorms are currently moving through Central Texas and are tracking southeast towards the coast. These storms have the potential to be severe in nature with large hail, damaging winds, and localized heavy rains being the main threats. An isolated tornado or two cannot be completely ruled out. This will be expected mainly in the Victoria Crossroads and portions of the Coastal Plains. Skies will be partly cloudy which could allow for the atmosphere to recharge this afternoon which could lead to another round of thunderstorms. This was represented with low to medium POPs over the area. Models have been all over the place with timing so confidence will be low in that regard. SPC has the northern portions of the Coastal Plains and Victoria Crossroads in a Slight Risk (level 2 of 5) and the areas just to the south of that in a Marginal Risk (level 1 of 5). Portions of the Victoria Crossroads will be in a Marginal Risk for Excessive Rainfall (at least 5% of flash flooding). Guidance is trending in a similar setup for Saturday as well with strong to severe storms though it should be isolated over the Victoria Crossroads. This will need to be closely monitored in future forecast cycles. Temperatures will remain on the warmer side with highs around 90-100 degrees across the area. Along the Coastal Bend and Brush Country with the combination of low to upper 70s dew points will lead to heat indices up to 114 possible. && .LONG TERM... (Saturday night through next Thursday) Issued at 534 AM CDT Fri May 31 2024 Key Messages: - Moderate to Extreme heat related impacts continue this weekend through the middle of next week. Low end rain chances (<20%) will continue into Saturday night as yet another mid-level shortwave trough tracks near the region. Most of the energy in association to this next passing disturbance is likely to stay north of the area, therefore the low end PoPs. Aside from this, expect drier conditions as we head into the latter part of the weekend into next week as a mid to upper level ridge over Mexico takes a stronger hold. The next longwave trough is progged to dig into the Northern Plains around mid to late week pushing a surface cold front across the state late in the week, but not much of an impact is anticipated for our area as the front is likely to stall before reaching the CWA. Increasingly hotter temperatures are in store Sunday through Wednesday next week with highs climbing to 105 or higher over portions of the Rio Grande Plains and Brush Country. The combination of very high temperatures and humid conditions will lead to heat index values in the 110-115 degrees range along with a Moderate to Extreme HeatRisk levels. Periods of Heat Advisory or even Warning are possible, especially Monday through Wednesday. Please use caution if you are planning outdoor activities. Remember to protect yourself by wearing light colored clothing, take frequent breaks and drink plenty of water. And don`t forget your pets! && .AVIATION... (06Z TAFS) Issued at 1046 PM CDT Thu May 30 2024 Clouds can be seen spreading across S TX this evening via satellite imagery. Currently CIGs are a mix of VFR and MVFR, but are expected to become predominantly MVFR between 06-09Z. Could briefly have MVFR VSBYs at ALI and VCT early Friday morning due to a mix of patchy fog and haze. VFR conditions are expected to resume by mid morning Friday across S TX. Gusts up to 25KT are expected to decrease through the night. There is a 30-40% chance of thunderstorms late tonight into early Friday morning across the VCT area. Have added VCTS to account for this possibility. Can not rule it out across COT, however, the chances are lower (10-20%). && .MARINE... Issued at 534 AM CDT Fri May 31 2024 Moderate to strong onshore flow will prevail through this afternoon before becoming generally moderate. This is expected to persist tonight through early next week, with occasional winds to strong levels over the southern bays and nearshore waters. There is a low to medium chance for showers and thunderstorms through Saturday night. && .PRELIMINARY POINT TEMPS/POPS...
