Synopsis for high island to the matagorda ship channel out 60 nm including galveston and matagorda bays
a tightening pressure gradient between high pressure to our east and lower pressure to our west will lead to moderate onshore winds, building seas and above normal tides through midweek. Chances for showers and storms return near the middle of the week as the next weather system approaches the region.

New AVIATION

SHORT TERM
(This afternoon through Wednesday Night)
Issued at 719 AM CDT Tue Apr 29 2025

Ridging across the Southern Plains/SE/E CONUS continues to shift eastward today as closed low approaches from the Desert Southwest.
Subsidence and dry mid-lower levels should work to suppress rainfall today, though modest PWs and weak impulses preceding the low will keep rain chances from being zero. This especially during the afternoon hours as daytime heating destabilizes the environment.
Warm conditions are still on the tap for today with highs in the 80s and lows in the upper 60s/70s. The tightening pressure gradient from the approaching disturbance should keep breezy southeasterly winds in place through mid week. Paired with the partly to mostly cloudy skies, this should make for fairly comfortable weather.

Wednesday should start to see more active weather as the aforementioned low/upper level trough pushes into the Southern Plains/Texas. A 25-30 knot LLJ sets up over SE Texas, with the jet axis positioned north/northeast of our area. Parameter space for this environment shows overall lower CIN than the day prior with greater instability. HRRR has ML CAPE ranging from 1300-2200 J/KG with SFC CAPE around 1500-2700 J/KG. 0-6KM Shear climbs above 35 knots, though cloud-layer shear remains rather low. Midlevel lapse rates range from 7.0-7.5 DegC/km, though the freezing level and WBZ level are rather high. HRRR model updraft helicity paint balls greater than 25m2/s2 largely keep north of our CWA, with only a few individual models showing clusters near the Brazos Valley/Piney Wood area. Besides shortwaves impulses, a weak cold front will also be approaching SE Texas late Wednesday night.
Interestingly enough, the 06z HRRR places this boundary further south than currently depicted in the current NBM/HRRR. Broader models trends suggest that it'll slow/stall, with convection petering out through the early morning hours of Thursday, though it's exact positioning is less certain for the moment.

The Storm Prediction Center has areas north of I-10/US-59 under a Marginal (level 1/5) Risk of Severe Weather. These areas are also under a Slight (level 2/4) to Marginal (level 1/4) risk for Excessive rainfall on Wednesday. These storms could produce damaging wind gusts and locally heavy rainfall, as well as large hail to a slightly lesser degree. Still, the severe risk is overall not very large given the lack of forcing available, so it's likely that we may only see scattered showers/storms with only a few stronger storms pulsing up. The heavy rainfall threat now looks more credible given the potential for the weak cold front to stall out over our northern counties.

LONG TERM
(Thursday through next Monday)
Issued at 1152 PM CDT Mon Apr 28 2025

With mid-upper trof making further eastward progress away from the area, the upper pattern will transition to a more quasi-zonal flow - but still allowing for scattered diurnally driven precip Thursday. Shower/tstm chances increase Friday and Friday night as a weak, slow moving frontal boundary moves closer and eventually into SE TX and serve as a focusing mechanism for precip. This boundary should make it close to the coast by Saturday morning then eventually put on the brakes as it loses support (unless mesoscale driven) for a further southward push. Slightly cooler/drier airmass is anticipated for a short while north of the front, but with pooling deeper moisture to its south returning back inland, southern and swrn parts of the CWA can probably expect some continued rain chances on Sat. As the next upper trof taking shape to our west, a building ridge should suppress, but not completely eliminate, chances of shra/tstms somewhat Sunday & Monday. 47

AVIATION
(18Z TAF Issuance)
Issued at 1222 PM CDT Tue Apr 29 2025

VFR conditions will generally prevail over the course of the afternoon and into the evening, with southeast winds at times producing gusts in the 20-25 knot range. Winds will relax somewhat overnight, but should remain elevated enough to inhibit the development of widespread fog. MVFR cigs should return to the area after sunset, and remain in place into tomorrow morning. Elevated south to southeast winds develop once again by late morning.
Looking slightly beyond the TAF period, thunderstorm potential returns to the forecast tomorrow evening as a frontal boundary approaches the area.

MARINE
Issued at 1152 PM CDT Mon Apr 28 2025

A tightening pressure gradient between high pressure to the east and lower pressure to the west will maintain moderate onshore winds and somewhat elevated seas. Have issued a small craft advsy for current winds being observed in Galveston Bay and adjacent nearshore waters...and caution flags elsewhere. We'll likely need a continuation of either SCEC/SCA flags for the next couple days as speeds/seas flirt with criteria. Chances for rip currents along area beaches will be on the moderate/high side and water levels will run above normal. The gradient loosens during the second half of the week with gradually subsiding winds/seas...although shower/storm chances gradually rise - especially Fri-Sat as a weak front sags closer toward the coast. 47
