Marine Weather and Tide Forecast for Giddings, TX

SHORT TERM
(Tonight through Wednesday night)
Issued at 1229 PM CDT Tue Apr 14 2026

Current visible satellite imagery shows quite an extensive cloud deck over the area that's just now finally starting to erode from south to north. We even had some areas of drizzle form which isnt surprising as the atmosphere remains extremely moist across the area. Most should remain dry through late this afternoon as we continue to mix up the atmosphere remaining capped. Our attention then turns to the west where an approaching dryline and attendant mid-level shortwave approach the area helping to ignite convection along and ahead of this boundary. Most Hi-Res model guidance is in fairly good agreement that initiation of convection should commence over northern Mexico and push across the border into Val Verde county by later this afternoon.

SPC currently has a level 2 of 5 risk for severe thunderstorms across Val Verde, Kinney, parts of Maverick and most of Edwards counties. The main risk being for large to very large (potentially 3+ inches) hail and sporadic damaging gusts. Additionally, an isolated tornado cannot be ruled out. A level 1 of 5 risk is places along and west of the I-35 Corridor. Agree with this as the most recent sounding at DRT shows the presence of steep mid- level lapse rates atop very moist low- level moisture just along and east of the dryline. Likewise models continue to hint at MUCAPE values of 1500 to 2500 J/kg along with 50-65kt of effective bulk wind shear and steep mid level lapse rates of 7-7.5 C/km building by this afternoon. All these factors continue to support and increase ones confidence that should convection form along this boundary we could see some very large hail late this afternoon and into this evening.

Convection should then begin to spread east northeastward into parts of the Southern Edwards Plateau before weakening and perhaps reaching the western Hill Country by late this evening. Most activity is expected to wane significantly after midnight as we lose mixing potential and storms begin to encounter more stable air to the east. Additionally, any convection that forms will have rich moisture to work with and will be capable of producing torrential rainfall with a quick 1-3 inches an hour not out of the question. As a result, WPC has an area along and west of a Llano to Kerrville to Carrizo Springs in a level 1 of 4 risk for excessive rainfall.

Depending on tonights convective evolution and how far east these storms make it will greatly impact our next shot for active weather tomorrow. Less storms tonight generally means more active weather for tomorrow with the opposite being true if we end up seeing storms progress further east as the atmosphere will need time to recover and reload. As such, SPC continues to keep us in a level 1 of 5 risk for the same areas as today with main risks being damaging wind gusts and large hail. Most Hi-Res models continue to struggle on the exact placement convection will occur and this is likely due to the uncertainty surrounding the evolution of the convection tonight. Regardless, with the upper level trough nearing our area Wednesday the more likely scenario would be convection forming over the Edwards Plateau and Hill Country and pushing off to the northeast.

Most activity should be well off to the north and east by overnight Wednesday as upper-level ridging starts to build in allowing many to finally dry out and warm up. Regarding high temperatures Wednesday, most should expect to find themselves in the mid 80s with areas that see more sun possibly nearing 90 degrees. Lows tonight and tomorrow night will remain abnormally warm with many not dropping below 70 degrees.

LONG TERM
(Thursday through next Tuesday)
Issued at 1229 PM CDT Tue Apr 14 2026

As alluded to briefly in the short term, upper-level ridging builds across the area by early Thursday and continues into Friday before a deep trough is forecast to bring an attendant cold front through most of North Central and South Central TX. As this happens expect convection to blossom out and ahead of this front as southerly low-level flow along with southwesterly flow aloft should help funnel in rich moisture from the Gulf. Expect convection to take advantage of this setup with WPC once again highlighting a level 1 of 4 risk in an area along and north of a Fredericksburg to Buda to La Grange line.

Once this front passes we should see much colder air spill in behind it with highs Thursday and Friday near 90 dropping into the 70s by Sunday. Additionally, expect some off and on showers Sunday into Monday as mid-level southwesterly flow remains. By Monday we should see the peak of this CAA with areas perhaps not making it out of the 60s especially across the Hill Country with a gradual warmup expected as southerly low-level flow finally returns by Tuesday.



AVIATION
(18Z TAFS)
Issued at 1225 PM CDT Tue Apr 14 2026

MVFR ceilings may linger for another hour over KSAT/KAUS and into the mid-afternoon for KDRT, though VFR conditions will be short- lived with redevelopment of MVFR to IFR ceilings again tonight into Wednesday morning. South to southeast wind may gust from 20-25 knots across the area through the evening. Models have been consistent in initiating storms near KDRT near 00Z today and have opted to include a TEMPO group for this possibility. Storm development may hinder the timing of low ceilings in the west tonight.
