GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 255 Pm Cdt Sun Apr 20 2025

Synopsis for high island to the matagorda ship channel out 60 nm including galveston and matagorda bays
southeast winds have managed to increase somewhat more than originally projected, placing galveston bay and the nearshore gulf back into small craft advisory criteria. Gusts up to 25 knots are expected through the rest of the afternoon and could continue into the evening and part of the overnight. Chance of showers and Thunderstorms increases by this evening and tonight. We think there will be a daily risk of showers and Thunderstorms through much of the upcoming week. Onshore winds and seas are expected to increase by the middle of the week.

SHORT TERM
(This evening through Monday Night)
Issued at 343 PM CDT Sun Apr 20 2025

The immediate term remains a fairly active period, with the potential some localized heavy downpours and/or strong thunderstorms. Latest analysis indicates the presence of a slow- moving frontal boundary pushing into the Brazos Valley with a broken line of showers/storms positioned ahead of it. The most recent suite of high resolution model guidance indicates the development of some stronger convection as the line pushes into the northern portions of the Houston Metro/the Piney Woods over the course of the late afternoon and evening. Environmental parameters support the development of a few stronger storms in these areas, with SB instability values in excess of 2000 J/kg and 0-1km SRH values in some locations in excess of 100 m^2/s^2.
Moisture remains plentiful with surface dew points in the upper 60s/near 70 and total PW near 1.5 in.

The consensus of HiRes guidance supports earlier forecasts showing the front stalling out along the immediate coast late this evening/overnight. As this occurs, we could see some localized pockets of heavy rain, which could presumably lead to a few instances of urban/poor drainage flooding depending on the location of the heaviest rainfall. Working in our favor, however, is a recent lack of measured rainfall and thereby drier soils/higher flash flood guidance values. Still, with the potential for a line of training storms so set up along the coast overnight and into tomorrow, this will be something to watch fairly closely. Overnight lows will have a fairly sharp gradient that will ultimately depend on the positioning of the front- with values in the 50s across the far northern zones and the low 70s south of I-10.

Rain may linger into Monday afternoon before activity dissipates by the early evening. Widespread cloud cover should inhibit heating somewhat tomorrow afternoon, with highs generally in the lower 80s. With a persistent southerly flow quickly returning tomorrow, look for lows mainly in the upper 60s to near 70.

LONG TERM
(Tuesday through next Saturday)
Issued at 343 PM CDT Sun Apr 20 2025

Guidance continues to show a fairly active period through the end of the upcoming week. A series of shortwave troughs embedded within a generally quasi-zonal midlevel flow will invigorate the development of showers and thunderstorms each day through Friday.
Rainfall chances will be aided by a persistent and steady onshore flow regime that will keep total PW values generally in the 1.5 to 1.75 inch range. Daily rainfall chances will sit anywhere from 30-70%, with the pattern generally favoring higher rainfall chances/amounts across the northern portions of the forecast area. Given the warm/unstable pattern, a few stronger storms can't fully be ruled out.

This week will certainly be characteristic of the march towards summer, with high humidity and temperatures in the 80s. Overnight lows will generally sit in the upper 60s to lower 70s.

AVIATION
(00Z TAF Issuance)
Issued at 555 PM CDT Sun Apr 20 2025

The forecast is unfortunately quite uncertain this evening, particularly for IAH, SGR, and HOU. A boundary slowly approaches from the west. Associated shra/tsra activity along the boundary will continue as this boundary pushes westward. The boundary is expected to stall. The exact location and timing of the stalling is one uncertain factor. The other uncertain factor is how long after we lose day time heating will tsra activity last. It is possible that tsra activity remains just west and north of IAH, keeping most of the heavy weather in CXO's and UTS's space. But it is also possible that we will have to contend with these storms in the heart of the Houston metro. Loss of day time could bring tsra to its demise as early as 03-04Z. But some high resolution guidance suggest TSRA could linger well after 06Z. Therefore, TAFs will need to be monitored for amendments this evening. Cigs are expected to trend MVFR overnight across the southern half of the region, mostly from CXO points south to the coast. Winds in the vicinity of the boundary will become light and variable, while remaining from the SE to the south of the boundary.

Forecast for tomorrow appears tricky as well, with another chance of scattered shra/tsra near wherever the boundary ends up.

MARINE
Issued at 343 PM CDT Sun Apr 20 2025

Strong southeast winds and hazardous seas will continue into this evening. Winds should ease somewhat overnight. However, seas may take longer to drop, potentially resulting in an extension in the Small Craft Advisory over the Gulf. While winds and seas decrease, there will be an increasing chance of showers and thunderstorms.
This is the beginning of an active pattern that will set the stage for daily shower and thunderstorm chances through much of the upcoming week. Onshore winds and seas are expected to increase again by the middle of the week.
